Where the year to June 1871 was one of consolidation after Imperial withdrawal, the financial year 1871–72 was one of settling routine. The Store Department now had a full year of independent colonial operation behind it. Its small body of storekeepers, clerks, armourers, arms cleaners and magazine keepers continued to support the Armed Constabulary, Militia and Volunteers, while the Inspector of Stores maintained the wider system of inspection and accountability.
The surviving accounts show that this activity was conducted on a more modest financial footing than the earlier draft suggested. The Store Department spent £2,607 2s. during the year, while the separate Inspector’s Department spent £1,244 7s. 6d. The distinction matters: inspection and departmental storekeeping were related functions, but Parliament accounted for them under separate votes.
Legislative and Financial Setting
The financial framework for 1871–72 continued under the Defence and Other Purposes Loan Act 1870. Its schedule authorised up to £160,000 for colonial defence costs, charges, expenses and liabilities for the year ending 30 June 1872, approximately NZ$28.8 million using the article’s working conversion of £1 = NZ$180 in 2026 values.[1]
The Appropriation Act 1871 applied funds to the service of the year ending 30 June 1872. The detailed outturn was subsequently published in the Public Accounts for 1871–72 and summarised in the Colonial Treasurer’s Financial Statement of 20 August 1872.[2]
The conversion to 2026 New Zealand dollars is indicative only. It is used to convey scale rather than to imply a precise modern purchasing-power equivalence.
Confirmed Store Department Expenditure
Vote 62, Store Department, recorded the following expenditure for the twelve months from 1 July 1871 to 30 June 1872:
Category
Actual expenditure
Approx. 2026 NZD
Storekeepers and clerks
£995 16s. 8d.
$179,250
Armourers and arms cleaners
£1,321 1s. 6d.
$237,794
Magazine keepers
£147 11s. 0d.
$26,559
Rent, advertising and contingencies
£142 12s. 10d.
$25,675
Total actual expenditure
£2,607 2s. 0d.
$469,278
The account is significant because it shows where the department’s effort was concentrated. Armourers and arms cleaners accounted for just over half of Vote 62, reflecting the labour required to inspect, clean and repair weapons distributed throughout the colony. Storekeepers and clerks formed the next-largest component, while magazine keeping and general operating expenses were comparatively small.[3]

The department therefore finished the year £49 19s. 8d. below its total spending authority. This was a small saving of about 1.9 per cent, suggesting close alignment between the provision approved by Parliament and the expenditure actually incurred.
The Separate Inspector’s Department
The Inspector of Stores was not charged to Vote 62. The inspection function appeared under Vote 61, the Militia and Volunteers Inspector’s Department. The Public Accounts recorded:

Approx. 2026 NZD

The £284 7s. 6d. spent on travelling and contingencies is firmer evidence of an active inspection function than the provisional £100 allowance used in the earlier draft. The accounts do not, however, identify the individual journeys made during the year, so any detailed itinerary must be supported from correspondence, Gazette notices or newspaper reports rather than inferred from the expenditure alone.[4]
Personnel and the Limits of the Accounts
The Public Accounts group salaries by occupational category and do not identify the individual recipients. It is therefore safer to present the names below as personnel associated with the Defence Stores during the period, rather than as a salary establishment reconstructed from Vote 62.

This nominal roll should not be read as proof that every person served for the full twelve months or that each salary came from Vote 62. In particular, the Inspector’s establishment was separately accounted for, and Armed Constabulary appointments could be charged elsewhere. The named roll is useful for institutional history, while the aggregate Public Accounts provide the reliable financial totals.
Armourer succession at Auckland: David Evitt, a former British Military Stores Armourer and long-serving government gunsmith, remained responsible for Auckland’s arms until his death on 23 February 1872. Although seriously ill, he reportedly completed the repair of one final rifle shortly before his death. His son, George Evitt, succeeded him as Government Armourer and held the appointment until 1888.
Arms, Carbines and the Technical Workload
The 1872 Annual Report of the Inspector of Militia and Volunteers provides direct evidence of the condition of the weapons that the Store Department’s armourers and arms cleaners had to support. The Inspector reported that the breech-loading cavalry carbines were generally in a very bad state. Five hundred Snider carbines had been ordered from England, but had not arrived by the date of the report.
The Enfield rifles issued to infantry corps were, with few exceptions, in indifferent condition after prolonged use. Their barrel grooves were becoming worn and would deteriorate further until the weapons became unserviceable. The Inspector warned that British manufacture of Enfield rifles and ammunition was declining and that failure to replace the existing stock progressively could result in a very large future rearmament cost.
Targets were another supply problem. Imported targets had been ordered but had not arrived, while targets manufactured locally for immediate use had proved far inferior to those made in England. These observations show that the Defence Stores were supporting not merely an accounting system but also an ageing weapons inventory, delayed overseas procurement, and the uneven quality of colonial substitutes.[5]
Auckland Defence Store and Magazine Arrangements
The Auckland establishment continued under Major William St Clair Tisdall with John Blomfield and John Price as clerks, George Evitt as armourer, Thomas Gibbins, John Penligen, Charles Philips and William Cook Rockley as arms cleaners, and John Broughton as magazine keeper.
The movement away from the magazine arrangements at Albert Barracks and the development of the Mount Eden site were part of a broader effort to place powder storage on a safer, more controlled footing. The Regulations for Gunpowder Magazines issued in 1872 established formal rules for the custody, storage and handling of gunpowder. The uploaded financial and militia reports do not, by themselves, establish the precise completion date of the Mount Eden works, so the physical development of the site should continue to be sourced from the Gazette, tenders, and contemporary newspaper reports.
Wellington Defence Stores, Mount Cook
At Wellington, the Mount Cook Depot on Buckle Street remained the principal southern store. Existing research identifies Henry Elmhirst Reader as Storekeeper, Alexander Crowe as clerk, Edward Metcalf Smith and Edwin Henry Bradford as armourers, William Warren, John Shaw, James Smith and Walter Christie as arms cleaners, and William Corliss as magazine keeper. Anderson’s Armed Constabulary storekeeping duties were closely connected with this establishment, although the accounts do not demonstrate that his salary formed part of Vote 62.
The large aggregate expenditure on armourers and arms cleaners in 1871–72 confirms that technical weapon maintenance was not a peripheral activity, but the highest single cost within the Store Department vote.
Volunteers, Cadets and Continuing Demand
The 1872 report recorded 6,042 enrolled adult Volunteers at 31 March 1872, of whom 5,101 were classed as efficient. The North Island accounted for 4,038 enrolled and 3,584 efficient Volunteers, while the South Island had 2,004 enrolled and 1,517 efficient. A further 1,443 Cadets were enrolled, of whom 1,222 were efficient.

The adult Volunteer total was lower than the 6,568 enrolled in the previous year, but it still represented a large and geographically dispersed body requiring rifles, carbines, ammunition, targets, accoutrements, repairs and accounting support. The Store Department had to sustain this demand with a central vote of only £2,607 2s. and a small network of permanent and part-time store personnel.[6]
Conclusion
The financial year from 1 July 1871 to 30 June 1872 was not a year of dramatic institutional change. It was a year in which colonial defence storekeeping became routine. The accounts show a compact Store Department that spent £2,607 2s., slightly below its authorised provision, while the separate Inspector’s Department spent £1,244 7s. 6d. and required supplementary authority for an £84 7s. 6d. excess.
The operational context was demanding. Cavalry carbines were in poor condition, Enfield rifles were wearing out, replacement Snider carbines and imported targets had not arrived, and locally made targets were unsatisfactory. At the same time, more than 6,000 adult Volunteers and 1,400 Cadets formed a dispersed customer base for arms, ammunition and equipment.
The department’s achievement lay in sustaining this system with limited resources. Storekeepers and clerks maintained custody and accounts; magazine keepers safeguarded ammunition; armourers and arms cleaners absorbed the largest share of departmental expenditure as they kept an ageing inventory serviceable. Rather than the provisional salary establishment of more than £3,400 suggested in the earlier draft, the confirmed record reveals a leaner organisation whose value rested in the technical and administrative work it performed across the colony.

Today, 12 July, would have been Corps Day for the Royal New Zealand Army Ordnance Corps. It also marks thirty years since the formation of the Royal New Zealand Army Logistic Regiment and, with it, the disestablishment of the RNZAOC. It is a fitting moment to look back, not with sentimentality but with appreciation for what the Corps actually was and what it left behind.
The RNZAOC was not lost so much as it moved into its next form. From the days of Henry Tucker onwards, the work of the Ordnance soldier was defined by one constant: continual adaptation. Its history is best understood not as that of a fixed institution that came to an end, but as one long process of change that continues today, under a different name.
Formed in war, tested by peace
The role of the Ordnance soldier expanded and contracted as the Army’s needs shifted around it. During the First World War, New Zealand Ordnance personnel served both at home and overseas, in Egypt, Gallipoli, Palestine, France, Belgium and the United Kingdom.
The interwar years brought progress alongside considerable uncertainty, including a period when the New Zealand Army Ordnance Corps came close to ceasing to exist altogether.
Mechanisation and a widening trade
The Second World War forced rapid adaptation once more. Ordnance soldiers served in every theatre in which New Zealand forces took part, adjusting to the demands of increasingly mechanised warfare. Bath and laundry services, ammunition support and specialist technical functions all became central to the Corps’ work during this period.
The later transfer of the Technical Trades to the New Zealand Electrical and Mechanical Engineers fits the same pattern rather than breaking from it. As military technology and technical specialisation advanced, responsibilities moved to where they made most sense — a recurring feature of the Corps’ story, not an exception to it.
A peacetime Corps that kept changing
Adaptation did not stop when the wars ended. Territorial Force personnel became an integral part of the RNZAOC, and the increasingly specialised management of technical stores gave rise to the Auto Parts trade. The Ammunition Technician trade evolved alongside the operational environment and, by the 1970s, had become the Army’s centre of expertise in explosive ordnance disposal.
Further change followed: the integration of women from the Women’s Royal New Zealand Army Corps, and then the transfer of the RNZASC supply trades into the RNZAOC in 1979. Less visibly, Ordnance personnel also adapted to the gradual introduction of electronic stores-management systems, progressing from early mainframe systems to the networked logistics systems in use by 1996.
The Corps at its height
By the mid-1980s, the RNZAOC had reached its peak. 1 Base Supply Battalion was, at the time, regarded as one of the most complex warehouse operations in New Zealand. Supply Companies were located at Hopuhopu, Waiouru, Linton and Burnham. Separately, stores sections were integrated within each RNZEME workshop, while an Advance Ordnance Depot maintained a New Zealand presence in Singapore. It was a Corps operating at scale, both at home and abroad.
That scale did not last. With the end of the Cold War came a peace dividend, and with it a gradual reduction in the size and reach of the Corps through the late 1980s and into the 1990s. This, too, was adaptation rather than decline for its own sake, the Corps reshaping itself to match a changed strategic environment, as it always had.
Towards Formed Deployments
RNZAOC soldiers had already deployed on operations in Korea, Malaya, Malaysia and South Vietnam, and others had served individually on peacekeeping missions. The 1990s added a further dimension, as Ordnance soldiers began deploying on operations as formed contingents, beginning with a Supply Detachment to Somalia, followed by two platoons, a shift that reflected both New Zealand’s changing military commitments and the increasingly integrated role of logistics support.
A Corps Spanning Generations
When the RNZAOC was disestablished in 1996, its youngest member was 17 years old and its oldest was 55. That span was more than a statistic. It represented a Corps that connected multiple generations of officers and soldiers, from those trained in long-established manual systems to those entering an increasingly digital and integrated logistics environment, within a single institution, at a single moment.
Continuity, Not Loss
The formation of the RNZALR did not erase the RNZAOC’s history; it became the next stage in a much longer process of adaptation. Titles, structures and trades changed, but the essential purpose held: to provide the Army with the equipment, ammunition, technical support and supply services needed to train, deploy and operate.
Thirty years on, the most fitting way to remember the RNZAOC is not to mourn its passing, but to recognise its enduring legacy, carried forward today within the RNZALR, particularly through its Supply trade. Adaptation was never evidence of weakness or decline. It was, and remains, one of the Corps’ defining strengths.
New Zealand Army Ammunition Technical Investigation from Shelly Bay to the Ammunition Technician Trade
Training with ammunition has always carried risk. Whether on a rifle range, during grenade training, in artillery practice, during demolition work, or while handling explosives in a depot or field environment, ammunition must function as designed, and soldiers must use it as directed. When either of those things goes wrong, the consequences can be serious and, in the worst cases, fatal.
For the New Zealand Army, the investigation of ammunition-related incidents is one of the important roles performed by Ammunition Technical Officers and Ammunition Technicians. Their purpose is not to assign blame. It is to conduct a technical appraisal of the ammunition, explosives, weapons, stores, and procedures involved, and to determine, as far as the evidence allows, what happened and why.
That distinction matters.
This is a historical and institutional narrative, not a technical investigation report. It draws on inquest records, commission findings and newspaper accounts to trace how the investigative function evolved. It does not attempt to reconstruct failure mechanisms to modern forensic standards, and readers with an Ammunition Technical trade background should read the technical detail in each case as illustrative of the investigative principle at work, not as a substitute for the original findings.
In the aftermath of an ammunition incident, particularly one involving injury or death, there is a natural desire to find an immediate cause. Was the ammunition faulty? Did the weapon fail? Did the operator make a mistake? Was supervision inadequate? Was the drill wrong? These are necessary questions, but they must be answered carefully. The role of the ammunition specialist is to establish the technical facts before drawing conclusions.
A sound ammunition investigation seeks to determine whether the ammunition was serviceable, whether it was being used within its design limitations, whether storage or handling may have affected its condition, whether a batch or lot may require restriction, and whether procedures, training, or equipment need to be amended. It is an evidence-based process, not an exercise in blame.
This article follows two connected stories. The first is the history of selected incidents involving the New Zealand Army and New Zealand military ammunition. The second is the evolution of the specialist technical structure needed to investigate them. Before New Zealand had Ammunition Technical Officers and Ammunition Technicians, accident investigation relied on commissions, coroners, artillery officers, submarine mining specialists, Defence Department officials, police and expert witnesses. Over time, those ad hoc arrangements gave way to formal inspection, proof (test-firing to confirm a batch is safe to use), surveillance (ongoing monitoring of the condition of stored ammunition), and technical control of ammunition.
Where the names of those killed are known, they are included. This is not to sensationalise the incidents, but to ensure that the technical lessons are anchored in the lives of the people who were lost. Ammunition accidents are often discussed in terms of natures (in ammunition terminology, a “nature” is a specific type or mark of munition, tracked separately from other types), batches or lots (ammunition manufactured together and tracked as a group, so a defect found in one can be traced to the rest), fuzes (mechanical or electronic devices that initiate a munition, as distinct from a burning safety fuse), guns, drills and procedures. Those details matter, but they should not obscure the human cost that gave urgency to each investigation.
Before the Ammunition Trade
The early New Zealand ammunition and explosives accidents of the 1890s and early 1900s occurred before the Army had a dedicated technical ammunition trade. These incidents were not investigated by Ammunition Technical Officers or Ammunition Technicians in the modern sense, because that professional structure did not yet exist.
Instead, investigations were conducted through the mechanisms then available: formal commissions, coroners’ inquests, police representation, Defence Department oversight, and the evidence of officers and men with practical experience in artillery, submarine mining, torpedo work, engineering and explosives.
This does not mean that the investigations lacked technical content. On the contrary, the evidence from Shelly Bay, Mahanga Bay and Fort Ballance shows that the inquiries were often highly technical. They examined explosive preparation, initiation, storage, testing, drill, gun mechanisms, breech closure, cartridge case behaviour, detonators, guncotton sensitivity, and the transmission of regulations. What was missing was not technical curiosity, but a permanent New Zealand military organisation whose standing function was to own ammunition inspection, investigation, records, testing and technical assurance.
The significance of the 1891, 1899 and 1904 inquiries is therefore not that they were conducted by ammunition specialists. They were not. Their significance lies in showing why ammunition specialists became necessary.
Shelly Bay, 1891: A Technical Inquiry Before a Technical Trade
On 5 March 1891, a guncotton explosion (guncotton being a nitrocellulose-based high explosive then used in mines and demolition charges) occurred at Shelly Bay during submarine mining work, killing Torpedomen William Densem, aged 22, and William Horrocks Heighton, known as William Ross, aged 35. Torpedoman Cornwall was also seriously injured in the blast.[1] The subsequent inquiry was conducted by two Royal Navy officers, appointed by the Governor through the Admiral commanding the Australian Squadron, who acted as Royal Commissioners tasked with determining the cause of the explosion.[2] The Commissioners found that the accident was caused by the overheating of a loaded primer tin (a sealed container holding percussion primers — small explosive charges used to initiate a larger charge) while its lid was being soldered on. Their report reconstructed the sequence of events in technical detail, identifying the location of the primer tins, the use and reheating of the soldering iron, the presence of dry guncotton, and the way heated gases and flame caused successive detonations.[3]
The Commissioners did not simply ask who was at fault. They examined the process, the workplace, the explosive stores, the instructions in force, and whether War Office memoranda had been properly circulated. Their findings were direct. They stated that solder should not be applied to cases containing guncotton, whether wet or dry, and that live charges fitted with detonators should not be stored in the mine store. They also observed that cases containing guncotton were not properly covered, that periodical testing had not been consistently recorded, and that there was a need for a “permanent responsible head” who could account for torpedo stores and other warlike material in the colony.[4]
That recommendation is especially important. Decades before New Zealand developed the Ammunition Technical Officer and Ammunition Technician structure, the Shelly Bay inquiry had identified the need for centralised technical responsibility for explosives, testing, records, and regulatory compliance.

The Commission’s report also demonstrates the value of investigation beyond blame. Captain Falconer, the officer responsible for the submarine mining operations at Shelly Bay, had his practice criticised, but the report also acknowledged his experience and familiarity with submarine mining.[5] The issue was not simply one man’s conduct. It was the wider system: how instructions were issued, how stores were controlled, how testing was recorded, and how dangerous processes were supervised.
In that sense, Shelly Bay stands as an early example of technical investigation into ammunition before there was an ammunition technical branch.
The following year’s Defence report confirms that two separate inquiries ran in parallel: the naval Royal Commission and a distinct civil court process, with the findings of both forwarded to the Government.[6] That dual-track approach, with military and civil investigations running side by side, is itself an early precursor to the layered, multi-source technical investigation later formalised under the Ammunition Technical Officer structure.
Mahanga Bay, 1899: When Experience Was Not Enough
On 7 August 1899, a fatal guncotton explosion occurred at Mahanga Bay during the demolition of an old electric searchlight pedestal at Point Gordon. The inquest into the deaths of Sergeant Octavius Olive, aged 38, Corporal Henry Blick, aged 53, and Sapper William Teague, aged 25, was opened at Mahanga Bay.[7] A fourth man, Sapper John James Head, was also injured in the explosion. Inspector Pender represented the police, Commissioner Tunbridge, Colonel Penton, Commandant of the New Zealand Defence Forces, and other military officers were present, and legal representatives appeared for the relatives of Corporal Blick and Sergeant Olive.[8]
Captain Falconer gave evidence that he had ordered the destruction of the old pedestal and that a guncotton mine had prematurely exploded while the work was being carried out. Sergeant Olive was tamping (packing the explosive firmly into place) the guncotton into a hole in the concrete, Blick was holding the box containing broken guncotton, and Teague was taking guncotton from the box and placing it into the hole. The main wires were reportedly not connected, and the detonators were later found intact, suggesting that the charge had not been fired electrically.[9]
The evidence was technically complex. Captain Falconer stated that he had no theory to explain the explosion and that similar methods had been used many times before without mishap. Torpedo Gunner Broderick of HMS Mildura, who had experience with naval explosives, examined the guncotton and found it satisfactory. Witnesses considered whether the explosion could have been caused by ignition, confinement, friction, percussion, a spark, faulty guncotton, or heating from the sun. Colonel Penton, while unable at that stage to attribute blame, stated that after the accident he would issue instructions that guncotton should be used in a damp state wherever available.[10]
The coronial inquest ultimately absolved the officer in charge of blame. The case was also referred to the Home Office in London for an independent scientific opinion, which upheld the jury’s finding. Following the accident, Penton ordered that all future demolitions be carried out only under “service” conditions and with “service” stores.[11] That sequence- inquest, independent expert review, and a resulting change to procedure- is the technical investigation cycle the modern Ammunition Technical Officer trade was later built to carry out as a matter of course.
Mahanga Bay is valuable because it shows the limits of experience and routine practice. Those involved were trained, experienced, and working according to methods they believed were accepted. Yet an unexplained premature explosion still occurred. The lesson for ammunition specialists is clear: repeated safe use does not prove that a practice is safe in all conditions. Technical investigation must consider not only whether the people were competent, but whether the explosive system, environment, method of preparation, and method of initiation provided adequate safety margins.
Mahanga Bay also reinforces a theme that runs through the history of ammunition incidents: when the technical cause is uncertain, the investigation must resist the temptation to settle too quickly on blame. Colonel Penton’s evidence, that he could not attribute blame at that stage, is precisely the approach later embodied in formal ammunition technical investigation.
Fort Ballance, 1904: Weapon, Ammunition and Drill
On 2 November 1904, Gunner John Amos Palmer of the Royal New Zealand Artillery was killed during firing practice at Fort Ballance when the breech-block of a 12-pounder quick-firer blew out. Several other members of the detachment were injured. The adjourned inquest was resumed at the hospital, with Inspector Ellison appearing for the police, Mr Levi for Palmer’s widow, and Mr Myers watching the case for the Defence Department.[12]

The inquest evidence concentrated on the weapon mechanism, the breech, the firing drill, the cartridge case, gas escape, heating, the number of rounds fired, and whether the gun could have fired unless the breech was properly closed. Members of the gun detachment repeatedly stated that the gun appeared to be in proper order, that the breech was properly closed, and that the correct firing drill had been followed. Bombardier Petersen, Gunner Slines, Gunner Sweeney and Gunner O’Neill each gave evidence from within the gun detachment.[13]
This was not an ammunition-branch technical inquiry. It was a coronial inquiry that relied heavily on practical artillery evidence. In a breech-loading gun of this kind, the cartridge case, expanding under firing pressure, seals the rear of the barrel; if that seal fails, hot gas can escape backwards toward the gun crew, which is why the questions below focus so heavily on the case and the breech. Yet the questions it asked were recognisably ammunition-technical questions. Did the cartridge case expand correctly to seal the breech? Was gas able to escape to the rear? Did electric or percussion firing have any bearing? Was the breech properly closed? Could drill or mechanism have allowed a dangerous condition to develop?
A later report on the inquest into the suicide of Gunner John Hay in 1906 is relevant to the theme of blame. Hay had apparently believed that others blamed him for Palmer’s death, but witnesses stated that they had not heard such blame and that Palmer’s death had been purely accidental.[14]That sad aftermath reinforces why technical investigation must be careful, evidence-based and clearly communicated. When the causes of an ammunition or weapon accident are uncertain, rumour and blame can fill the gap. That is why establishing what happened is only half the task; the other half is preventing unsupported assumptions from hardening into accepted truth.
From Magazine Keepers to Ammunition Technical Specialists
The early inquiries at Shelly Bay, Mahanga Bay, and Fort Ballance show why New Zealand eventually needed a dedicated technical ammunition function. In the nineteenth century, responsibility for ammunition and explosives sat largely with those who managed powder magazines, artillery stores, submarine mining stores and Defence Stores Department holdings.
Ammunition and explosives were imported from Britain and Australia, with powder magazines established at Mount Cook in Wellington and Mount Albert in Auckland. Responsibility for handling and storing these stocks sat with qualified individuals from the British Military Stores Department, Royal Artillery and Royal Engineers. After the withdrawal of Imperial forces in 1870, responsibility for New Zealand’s magazines and ammunition transferred to the Defence Stores Department, with later facilities established at Mount Eden in Auckland and Kaiwharawhara in Wellington.[15]
This early system provided practical control of magazines and ammunition, but it was not yet a specialist ammunition technical branch in the modern sense. When something went wrong, expertise had to be assembled from artillery officers, submarine mining personnel, naval torpedo specialists, police, coroners, commissions and Defence Department representatives.
By the late nineteenth century, New Zealand had also developed local ammunition manufacture. Major John Whitney’s ammunition interests evolved into the Colonial Ammunition Company in 1888, which produced small-arms ammunition for the New Zealand Government. Under the government contract, the state supplied powder while the company manufactured the cartridges. Each batch then underwent government inspection and testing before acceptance.[16]
That inspection process is significant. It shows that the principles later associated with ammunition technical work, inspection, proof, surveillance, testing and acceptance were already present before the formal trade structure existed. However, they were dispersed across different responsibilities rather than held by a single dedicated ammunition technical organisation.
The First World War and its aftermath accelerated the need for specialist technical control. The organisational titles below changed more than once over the following decades, but the underlying job, technical control of ammunition, stayed essentially the same throughout; readers mainly need the end point, that the modern Ammunition Technical Officer and Ammunition Technician titles arrived in 1961. Administrative control of the New Zealand Army Ordnance Section of the Royal New Zealand Artillery passed to the New Zealand Army Ordnance Corps (NZAOC) on its formation in 1917. Concurrently, technical control of ammunition passed to the Inspection Ordnance Officer of the NZAOC.
During the interwar period, the Inspecting Ordnance Officers Branch consisted of only a small number of staff officers. These included Major William Ivory, RNZA, who served from 2 January 1921 to 6 April 1933, and Captain I. R. Withell, B.Sc., RNZA, who served from 1933. The branch expanded rapidly during the Second World War as ammunition depots were established at locations including Ngaruawahia, Waiouru, Makomako, Kuku Valley, Belmont, Mount Somers, Alexandra, Glentunnel and Fairlie. Post-war, the ordnance ammunition trades comprised Inspecting Ordnance Officers and Ammunition Examiners.
In 1961, following United Kingdom practice, the titles changed. The Chief Inspecting Ordnance Officer became the Chief Ammunition Technical Officer; the Senior Inspecting Ordnance Officer became the Senior Ammunition Technical Officer; District Inspecting Ordnance Officers became District Ammunition Technical Officers; Inspecting Ordnance Officers became Ammunition Technical Officers; and Ammunition Examiners became Ammunition Technicians.

The modern Ammunition Technical Officer and Ammunition Technician structure, therefore, did not appear out of nowhere. It grew out of decades of experience in magazine management, ordnance inspection and proof, ammunition manufacture, explosive accidents, unexploded ordnance, and the need for independent technical advice. The Flaming “A” badge, adopted in 1971, symbolises the hazardous and highly skilled trade, but the professional roots of the role reach much further back to the early colonial handling of powder, guncotton, shells, and small-arms ammunition.
The 1932 Marton bus bombing also illustrates the development of the technical role beyond conventional ammunition.[17] Long before modern Explosive Ordnance Disposal existed as a military speciality, the Inspecting Ordnance Officer was called upon to examine a suspicious explosive device and later give expert evidence in court. The case has been described as a proto-EOD moment because it shows the State turning to a recognised military explosives authority to identify, reconstruct, control and report on an improvised explosive incident.[18]
Brocton Camp, 1918: When the Ammunition Works as Designed
Not every ammunition accident is caused by faulty ammunition.
On 19 April 1918, Lieutenant Randolph Gordon Ridling, New Zealand Rifle Brigade, was instructing reinforcement troops in the use of the Mills bomb at Brocton Camp, Staffordshire. A nervous trainee fumbled a live grenade after removing the pin, panicked, and dived into the corner of the bombing bay. Ridling pulled the man to shelter and was wounded when the grenade exploded. He was later awarded the Albert Medal for his actions.[19]
Public accounts of the incident point to panic and drill breakdown rather than a munition defect. That is exactly why the case is instructive. Even where an initial account suggests operator error, an ammunition technical investigation must still exclude ammunition failure.
Was the grenade correctly issued? Was it serviceable? Was the fuze operating within expected timing? Was the correct type of grenade being used for the training activity? Did the layout of the throwing bay allow an error to become fatal? Were the instructor and trainee positioned so that a failed throw or hesitation could be managed safely?
The ammunition may have functioned exactly as designed, but the incident still required technical understanding. Ammunition investigation is not limited to proving that a round, grenade, shell or fuze failed. It also helps establish when the ammunition did not fail, and when the true lesson lies in training design, supervision, safety margins or drills.
Trentham, 1942: Variability, Realism and Fatal Consequence
The best New Zealand example of the complexity of ammunition investigation is the grenade fatality at Trentham Military Camp on 7 February 1942.
During grenade instruction at the Army School of Instruction, an “emergency grenade” prematurely detonated. The incident resulted in the deaths of Major Richard James Dunlop Davis, New Zealand Staff Corps; Sergeant Robert Andrew Peters; Acting-Sergeant Roland Stephens Thomson; Corporal Richard Mark Geard; and Acting-Sergeant Herbert Henry Wood. Davis, Peters, Thomson and Geard died on 7 February. Wood died of his injuries on 8 February.[20]

The grenade was not a standard factory-produced munition. It was an expedient design based on components of the Mills grenade, adapted for local manufacture. Instead of an integrated, mechanically controlled fuze system, it used a short length of commercial safety fuse, approximately 3 inches long.
The training sequence followed accepted practice at the time. After trainees threw live grenades, the instructor assembled and demonstrated the emergency grenade in front of the class. The fuse was ignited and began to burn. Witnesses observed irregular behaviour, with the fuse appearing to falter or extinguish momentarily. The instructor intervened, flicking the fuse, after which it resumed burning from a lower point. Seconds later, the grenade detonated while still in his hand.
The technical evidence, as reported at the time, did not point neatly to a single simple cause. Lieutenant Colonel I. R. Withell, Chief Inspector of Munitions, gave evidence that the design was not considered inherently unsafe. The nominal burn time was approximately seven seconds, inspection procedures were in place, and instructors were trained to check components before use. Post-incident testing suggested that even damaged or kinked fuses generally burned within expected tolerances.
Yet the system still failed.
The danger lay not necessarily in a single defective item, but in the interaction of several factors: a short, manually prepared length of commercial fuse, variability in fuse burn behaviour, a close-proximity demonstration, and human intervention after ignition. Each factor could be understood in isolation. Together, they eliminated the margin for error.
Cases like this are why technical investigation of ammunition is essential. The question is not simply, “Who made a mistake?” It is, “What combination of design, material, preparation, drill, environment and human intervention allowed a fatal outcome?”
The Trentham case also demonstrates the danger of judging earlier practice only by modern standards. During the Second World War, training placed a premium on realism. Soldiers were expected to handle live munitions and to understand their weight, timing and effect. Modern simulation systems and high-fidelity inert training aids did not exist. In that environment, live and expedient training systems could be considered necessary and reasonable.
The lesson, however, was clear. Realism without adequate control can become unacceptable risk. Modern explosive ordnance training seeks to eliminate unnecessary variability, separate training from explosive hazard wherever possible, use inert or simulated systems when appropriate, and ensure that live ammunition is used only under tightly controlled conditions.
Wartime Unexploded Ammunition: Foxton, Hastings and Napier
Ammunition danger does not end when a range practice or training activity finishes. In January 1945, public warnings were issued after serious accidents involving old ammunition, including a fatal accident to one child and injuries to others at Foxton, and a serious accident to a schoolboy at Napier. The Minister of Defence warned the public, particularly children, not to handle shells, bombs or ammunition of any kind, and to notify the police or nearest army authority instead.[21]
A related Hastings report identified the shell involved in an accident as a six-pounder manufactured in 1902. Although it was described as a “dud”, an Army official pointed out that the projectile still contained a charge and could not be treated as harmless simply because it was old or had apparently failed to function when fired.[22]
These reports are important because they show another side of ammunition technical work: public safety and the management of unexploded ordnance. The Minister noted that live ammunition was being found in former live-firing areas, bombing ranges, sea beaches and other locations. He also acknowledged that, despite stringent regulations and post-practice searches, some unexploded projectiles could remain unrecovered, especially in sandy country.
For Ammunition Technical Officers and Ammunition Technicians, such incidents underscore the enduring principle that ammunition must be treated as dangerous until it has been technically assessed. Age, corrosion, previous handling, or apparent failure do not make ammunition safe. A shell, bomb, grenade or cartridge may remain hazardous long after its original military use has been forgotten.
Waiouru, 1959: Freezing a Nature Pending Technical Findings
On 14 February 1959, two Territorial gunners, Gary Winston Churchill and Brian Roland Haskell, were killed during exercises at Waiouru when a shell apparently exploded in the breech of a 25-pounder gun. Three others were injured. The New Zealand Army withdrew that type of 25-pounder ammunition from use and kept it “frozen” pending receipt of the court of inquiry’s accident report from the United Kingdom, from where the ammunition had been supplied.[23]
The Army’s response shows ammunition control in action at its strongest. It did not simply treat the event as an isolated gun accident. It restricted the ammunition nature pending technical investigation. That decision reflects the core logic of ammunition safety: when there is a possibility of a technical defect, similar ammunition must be controlled until the risk is understood.
The 1959 Waiouru accident sits naturally beside the later FH-2000 accident of 1997. Both involved artillery ammunition, both required technical investigation, and both raised the possibility that the incident was connected to ammunition or fuze performance rather than solely to operator action. Together they show why ammunition investigations must look beyond the individual round and ask whether a wider batch, lot, nature or supply source may be affected.
Waiouru, 1974: The Human Factor in Grenade Training
On 13 February 1974, Sergeant Murray Ken Hudson, Royal New Zealand Infantry Regiment, was killed during grenade training at Waiouru Military Camp. Hudson was supervising a training exercise when Sergeant G. Ferguson accidentally armed a grenade and froze. Hudson ordered him to throw it, then attempted to force the throw by grasping Ferguson’s hand. The grenade exploded, killing both men. Hudson was posthumously awarded the George Cross.[24]
As with Brocton in 1918, the public record points to operator failure and drill breakdown rather than an ammunition defect. But again, this does not remove the need for technical investigation.
In any such incident, an ammunition specialist would still need to confirm the nature of the grenade, its serviceability, the condition and function of the fuze, the timing sequence, and whether any batch- or storage-related concerns existed. Only once those technical questions were answered could the Army properly conclude that the ammunition functioned as designed and that the lesson lay in training, procedure, supervision or range layout.
This distinction is important. A soldier’s hesitation or error may be the visible event, but the purpose of investigation is to identify the system conditions that allowed that error to become fatal. Was the training layout adequate? Was there enough physical separation? Were instructor intervention drills realistic? Were the commands clear? Were safety arcs, pits, bays and emergency actions designed to preserve life once a grenade was armed?
Establishing what failed is not the end of the job. The specialist also helps commanders understand whether the ammunition, the weapon system, the training design and the human factors combined safely, or whether the system relied too heavily on perfect human performance.
Waiouru, 1982: Blind Ammunition and the Continuing Hazard
On 26 June 1982, Army Regular Force cadet Bryce Gawler, aged seventeen, of Rotorua, was killed at a Waiouru training area in an accident involving “blind”, or unexploded, ammunition. Two other cadets were injured: Philip Koziel, aged seventeen, of Nuhaka, near Wairoa, seriously; and Paul Clarkin, aged seventeen, of Hamilton. The injured cadets were taken to Taumarunui Hospital, and the Army convened a court of inquiry to investigate the accident.[25]
This incident connects the wartime warnings about unexploded ammunition in 1945 to the modern training environment. Even on an established military training area, unexploded ammunition remains a serious hazard. The issue is not only whether ammunition functions correctly when fired, but what happens when it fails to function and remains in the field.
Blind ammunition creates a delayed risk. It may be encountered by later users of the range, by soldiers conducting unrelated training, or by personnel who do not recognise the item or understand its condition. The technical questions are therefore broader than the immediate accident: what nature of ammunition was involved, why had it failed to function, how had it remained undetected, what range clearance procedures were in place, and what controls were needed to prevent recurrence?
For ammunition specialists, the 1982 Waiouru incident reinforces the importance of range clearance, reporting of blinds, explosive ordnance recognition, and the principle that unexploded ammunition must be left to qualified personnel.
Waiouru, 1997: Faulty Fuze, Batch Risk and Technical Control
The 9 March 1997 FH-2000 artillery accident at Waiouru provides a modern example of the technical investigation function.
During a live-firing exercise conducted by the 23rd Battalion, Singapore Artillery, at Waiouru Army Camp, a 155 mm artillery round exploded in the barrel of an FH-2000-gun howitzer. Two Singaporean servicemen, Third Sergeant Ronnie Tan Han Chong and Lance Corporal Low Yin Tit, were killed. A further twelve servicemen were injured, including a New Zealand Defence Force staff sergeant who was present as a liaison officer and observer.
A Committee of Inquiry convened by Singapore’s Ministry of Defence found that the most probable cause of the accident was a defective fuze fitted to the 155 mm projectile, according to the published findings; this account does not go further into the specific fault mode than that Committee’s public report does. The defective fuze resulted in the premature explosion of the round. Following the incident, the lot of fuzes from which the defective fuze had come was X-rayed, with approximately 1.3 per cent found to be defective.[26]
The case shows clearly why ammunition technical investigation extends beyond the immediate accident scene. Once a faulty fuze was identified as the likely cause, the question became much wider than the damaged gun and the casualties. Were other fuzes from the same lot unsafe? Had the defect been introduced during manufacture? Was the fault visible through inspection? Had acceptance testing, supplier assurance or sub-contractor control failed? Should the lot be withdrawn, screened, restricted or destroyed?
The technical response had to connect the failed component, the batch, the weapon system and the method of loading. That is the heart of ammunition technical work. It is not enough to know that an explosion occurred. The specialist must determine whether the same conditions exist elsewhere in the stockpile and whether other personnel could be exposed to the same risk.
The Investigative Role of the Ammunition Specialist
Across these incidents, the recurring theme is not blame but understanding.
Ammunition Technical Officers and Ammunition Technicians bring a particular form of expertise to post-incident investigation. They understand ammunition design, fuzing systems, explosives, propellants, packaging, surveillance, storage, deterioration, compatibility, handling and disposal. They are trained to look at the technical system as a whole.
In a post-incident setting, their work may include:
preserving technical evidence before it is disturbed;
identifying the ammunition nature, lot, batch and condition;
examining fragments, fuzes, cartridge cases, propellant, packaging and weapons;
determining whether the ammunition functioned as designed;
assessing whether storage, transport, age, environmental exposure or handling may have affected performance;
considering whether similar ammunition should be quarantined, restricted, inspected, tested or withdrawn;
advising commanders on whether training may continue and under what controls; and
recommending changes to drills, range procedures, supervision, equipment or technical instructions.
In some cases, the finding may be that the ammunition failed. In others, the ammunition may have functioned correctly, and the cause may lie in procedure, handling, supervision or human performance. Frequently, the answer is a combination of factors.
That is why premature blame is dangerous. If investigators assume the operator was at fault, a defective batch may remain in service. If they assume the ammunition was defective, a dangerous training practice may continue unchanged. The technical investigation must remain open to both possibilities until the evidence is understood.
Inspection Before Incident
Technical ammunition work is also preventative.
Inspections can identify deterioration, incorrect packaging, damaged stores, environmental effects, suspect lots, or unsafe conditions before an incident occurs. Ammunition surveillance and technical inspection allow commanders to make informed decisions about what may be issued, what must be restricted, and what should be destroyed.
The 1959 Waiouru and 1997 FH-2000 accidents both show this principle in practice, the first at the level of a single ammunition nature, the second at the level of a fuze batch. In each case, the investigation did not stop with the failed item; it asked whether the same defect existed elsewhere in the stockpile.
The Trentham case shows a different but equally important lesson. Even if individual components appear to function within tolerances, the design of the training system may still be unsafe if it contains uncontrolled variability and depends on human intervention after initiation. Technical safety is not only about whether a component passes inspection. It is also about whether the complete system provides enough margin for error.
From Accident to Doctrine
The development of modern ammunition practice has been shaped by incidents such as these. Every serious occurrence forces the Army to:
Ask whether existing procedures are sufficient.
The lessons are consistent.
Live ammunition must be used only where the training value justifies the risk.
Realism must be subordinate to control.
Systems should not rely on human correction after initiation.
Training design must assume that people may hesitate, misread, freeze or make mistakes.
Unexploded ammunition must be treated as dangerous until technically assessed.
Ammunition defects must be investigated at the batch and stockpile levels, not only at the incident level.
Technical findings must be translated into practical changes.
These principles are now embedded in modern ammunition and explosive ordnance practice. They are the result of experience, investigation and institutional learning.
Conclusion
Ammunition incidents are rarely simple. A primer may explode because heat was applied during preparation. Guncotton may detonate during demolition work despite the presence of experienced personnel and apparently familiar procedures. A breech may fail even when the gun crew believes the weapon is correctly prepared. A grenade may function correctly and still kill because the drill failed. A fuze may be defective, but only reveal itself when combined with a particular loading force. A shell fired decades earlier may still kill or injure because it remains live as unexploded ordnance.
This is why New Zealand Army Ammunition Technical Officers and Ammunition Technicians remain essential.
Their role after an incident is not to ask, “Who is to blame?” Their task is to ask, “What happened, why did it happen, and what must be changed to prevent it happening again?”
That approach honours those who have been injured or killed in ammunition incidents far more effectively than blame ever could. It turns loss into evidence, evidence into lessons, and lessons into safer training for those who follow, just as it has done for more than a century of New Zealand ammunition history.
The history of ammunition accidents in New Zealand military service, from Shelly Bay, Mahanga Bay and Fort Ballance, through Trentham and Waiouru, shows that ammunition safety has always depended on technical knowledge, disciplined investigation, accurate reporting and the willingness to learn from failure. That is the lesson history keeps repeating: each generation encounters its own version of the same failure, sometimes at fatal cost, and each generation has had to relearn that understanding, not blame, is what actually prevents the next one.
For the Ammunition Technical Officer and Ammunition Technician, that remains one of the most important duties of all.
The Trentham 1942 grenade fatality currently provides the strongest New Zealand historical example for explaining the complexity of ammunition technical investigation. The Waiouru 1959 25-pounder accident and the Waiouru 1997 FH-2000 accident provide strong examples of technical control, suspect ammunition, and batch or nature-level risk.

New Zealand Army Logistics Preparation to 30 June 1941
This article examines the New Zealand Army’s logistics preparations in New Zealand up to 30 June 1941, immediately before the wider wartime expansion that followed the deterioration of the Pacific situation later that year. Its focus is not simply on weapons and ammunition, but on the home-base logistics system needed to make them usable: Ordnance establishments, ammunition reserves, workshops, transport, stores, infrastructure, civilian labour, inspection, and the administrative machinery required to turn equipment into capability.
Main Ordnance Depot Cricket team, 1930s, the men who were the foundation of the NZAOC’s wartime expansion
This distinction matters. From 1940, New Zealand was also building a deployed expeditionary logistics organisation in Egypt and the Middle East to support the 2nd New Zealand Expeditionary Force. That overseas system drew away many experienced Regular Force officers and soldiers who had served through the interwar years, including key logistics personnel whose expertise was urgently needed both abroad and at home. This article does not attempt to examine the full logistics system deployed by 2 NZEF. Instead, it concentrates on the logistics situation within New Zealand, where the Army still had to mobilise, equip, store, maintain, feed, fuel, transport, and administer a rapidly expanding force while also supporting overseas commitments.
By mid-1941, New Zealand had not reached logistical abundance. It had, however, moved beyond passive austerity. Rearmament was underway, urgent orders had been placed, ammunition deficiencies were being addressed, infrastructure requirements had been costed, and the limitations of the small pre-war New Zealand Army Ordnance Corps, New Zealand Army Service Corps, and Mechanical Transport systems were becoming increasingly clear.
New Zealand’s rearmament did not begin suddenly in 1939, nor did it begin only because Major-General P. J. Mackesy reported on the state of the Military Forces. By the late 1930s, the Army, the NZAOC, and the NZASC were already working within their limited means to prepare for a more demanding form of war. Requisitions were being placed for modern weapons, ammunition, signalling stores, coast-defence equipment, anti-gas equipment, tentage, camp equipment, and technical stores. At the same time, the supply and transport system was slowly shifting from a horse-based structure towards motorised transport. The process was real, but it was limited, uneven, and too slow to overcome two decades of interwar economy before the Second World War arrived.
Wider strategic assumptions also shaped the Army’s position. New Zealand relied heavily on the Royal Navy, imperial defence, and the Singapore Strategy for its ultimate security. When rearmament resumed in the mid-1930s, air power received the clearest political and financial priority, leaving the Army to rebuild from a weaker base.
The shift from a 1937 NZAOC establishment of 44 military personnel and 122 civilians to an April 1939 establishment that identified 10 officers and 38 WO1s and other ranks in the Armourer, Armament, and Ammunition sections should not be overstated as dramatic numerical growth. What it does show is that rearmament was beginning to expose the need for a more clearly defined specialist NZAOC structure. The Army was not merely acquiring weapons and equipment; it also had to create the trained military depth needed to inspect, maintain, store, account for, issue, and sustain them. When the position of the NZASC is added, the wider point becomes clearer still. New Zealand’s Army was not simply short of modern equipment. It was short of the trained logistics capacity required to move, feed, fuel, maintain, and sustain a modern force. Rearmament was therefore not only an equipment programme, it was also a logistics mobilisation.
Imperial Defence, Austerity, and Normalised Risk
The pre-war Army’s condition can be understood through the concept of normalisation of deviance.[1] In this context, it does not mean that officers, soldiers, public servants, or logisticians were careless. It means that the Army gradually became accustomed to operating under constrained, abnormal, and improvised conditions. Reduced establishments, limited training, obsolete equipment, small ammunition reserves, civilianised logistics staff, thin supply and transport arrangements, and inadequate mechanical depth became part of the accepted interwar operating environment.
This process was shaped by more than local economic measures. New Zealand’s defence policy in the 1920s and early 1930s operated within a wider British imperial framework, including the assumption, formalised in Britain’s “Ten Year Rule”, that no major war was likely within a ten-year planning horizon.[2] As a Dominion of the British Empire, New Zealand’s ultimate security was still expected to rest heavily on the Royal Navy and the wider imperial defence system, especially the Singapore Strategy.[3] This strategic setting reinforced pressure to limit defence expenditure and encouraged the view that the Army could remain small in peacetime, with expansion to follow if danger returned.
Of all the Dominions, New Zealand showed particularly strong loyalty to Britain between the wars, but this loyalty did not remove the strategic anxieties created by New Zealand’s Pacific location. By the 1920s and 1930s, New Zealand leaders were already concerned that British policy did not always account for the security needs of Australia and New Zealand. This was reflected in criticism of the British reluctance to proceed with the Singapore base and of actions that appeared to weaken the collective security system on which New Zealand believed it was especially dependent. In that setting, New Zealand’s reliance on imperial defence was not passive ignorance. It was a strategic choice made by a small Dominion whose defence planning, expenditure, and Army establishments were shaped by the assumption that the main shield would be imperial sea power rather than a large standing land force.[4]
The reductions of 1930 to 1931 were central to this process. Introduced as emergency economic measures during the Depression, they reshaped what the Army expected of itself. The suspension of compulsory military training, the contraction of the Territorial Force, and the civilianisation of much of the NZAOC’s clerical and stores workforce created a much smaller defence system. The NZASC was also affected by the same economic climate, reduced training base, and limited vehicle holdings. What began as austerity became the baseline from which later mobilisation had to proceed. The effect was not simply financial; it was organisational and cultural. The Army learned to survive on too little.[5]
When the international situation deteriorated in the mid-1930s, New Zealand began to rearm, but the emphasis was uneven. Air power appeared to offer a modern, technologically advanced, and comparatively efficient means of defending an isolated maritime country.[6] The Cochrane review of New Zealand’s air defence requirements in 1936 reinforced this direction, and the Air Force Act 1937 separated the air arm from the Army and established the Royal New Zealand Air Force as an independent service.[7] Major investment followed in air bases, equipment, and training infrastructure. Air power was increasingly seen as the modern way ahead.
The result was that the Army became, in practical terms, the “Cinderella service”. This phrase should not be read as meaning that no one cared about the Army, or that Army officers were inactive. Rather, it captures the period’s order of priorities. The Navy and imperial sea communications remained central to strategic thinking, the Air Force attracted the most visible modern investment, and the Army was left to manage with a small regular cadre, a weakened Territorial system, ageing equipment, limited motor transport, inadequate ammunition reserves, and a logistics structure still shaped by the interwar economy.
This does not mean New Zealand ignored preparedness. The evidence points in the opposite direction. During the interwar period, the Army continued to plan, train, revise mobilisation arrangements, conduct exercises, experiment with mechanisation, and order modern equipment where possible. New Zealand was not asleep. It was alert, but constrained.
[8]The problem was more subtle. The Army adapted to scarcity so successfully that scarcity itself became embedded in the system. Reduced manpower, limited ammunition, ageing equipment, inadequate transport, and civilianised stores support were no longer seen only as emergency conditions to be corrected at speed. They became the environment within which the Army learned to function.
The limits of that system were exposed publicly by the Four Colonels’ Revolt. Senior Territorial officers protested the condition and direction of the Territorial Force, challenging a system in which reduced strength, limited training, poor morale, and inadequate equipment had become accepted as normal. Their protest breached military regulations, and the officers were placed on the retired list rather than court-martialled.[9] Yet the significance of the episode lies less in the disciplinary outcome than in what it revealed. By the late 1930s, informed military opinion recognised that the Army’s constrained condition was not simply economical, it was dangerous.
Seen through the lens of normalisation of deviance, the revolt was a warning sign. It showed that some officers were no longer willing to accept reduced establishments, weak Territorial strength, limited equipment, and low morale as normal. This interpretation avoids two extremes. It avoids the simplistic claim that New Zealand ignored defence between the wars. It also avoids the opposite error, suggesting that because planning existed, the Army was adequately prepared. The reality sits between the two. Interwar austerity, imperial defence assumptions, reliance on Singapore, and the prioritisation of air power created a force that was professionally aware and adaptable but also conditioned to operate below the level that modern war would demand.
Rearmament Before War
It would be misleading to suggest that New Zealand’s military rearmament began only with the emergency orders placed after the outbreak of war. The NZAOC files from the late 1930s show that a limited, uneven, but genuine process of re-equipment had already begun.
The evidence is scattered through requisitions, stock returns, and NZAOC correspondence rather than presented as a single grand programme. That in itself is revealing. Rearmament before 1939 was not a dramatic national mobilisation, but a piecemeal process of ordering selected modern weapons, replenishing ammunition, improving coast defences, obtaining technical stores, and trying to keep existing equipment serviceable.
Some requisitions reached back into the mid-1930s. Outstanding High Commissioner requisitions included entries dated from 1935 onward for detonators, fuzes, guncotton, mortar cartridges, grenades, and related explosive stores. The same schedules also recorded requisitions for 1936, 1937, and 1938: directors, switchboards, wireless components, mortar fittings, rangefinders, survey equipment, smoke generators, and other technical stores. This shows that the Army was already attempting to rebuild elements of its technical and ammunition base before the immediate pre-war crisis.[10]
By 1938 and 1939, the pattern had become more clearly connected to modern fighting equipment. The NZAOC schedules record orders for Bren guns and equipment, 3-inch mortars, 3-inch mortar equipment for mortars already in store, and QF 2-pounder carriages and equipment. Other entries included Boys anti-tank rifles, anti-gas equipment, medical equipment, tentage, and camp equipment. These were not simply replacements for worn-out stock. They represented the first stages of a deliberate effort to align New Zealand’s forces with contemporary British practice.
New Zealand’s limited rearmament was more forward-looking than it might first appear. Where funds and British supply allowed, New Zealand sought access to modern British-pattern equipment before, or almost as soon as, those items were accepted into British service. Orders and requisitions in the late 1930s included Bren guns, Boys anti-tank rifles, 3-inch mortars, 2-pounder anti-tank equipment, modern rangefinding stores, defence electric lights, searchlights, signalling equipment, and associated technical stores. These were not obsolete leftovers or belated purchases of discarded equipment. In several cases, they represented equipment at the leading edge, and sometimes the bleeding edge, of contemporary military technology. They were the types then reshaping British and imperial forces.
This distinction matters. New Zealand was not indifferent to modernisation, nor unaware of the direction in which British military practice was moving. It was attempting to align itself with the newest available imperial standards, including weapons, instruments, communications equipment, and technical systems that were only just entering wider British service. The weakness lay elsewhere: finance, British production capacity, imperial priority, shipping, and the small scale of New Zealand’s requirements meant that modernisation could be recognised and even ordered well before it could be delivered in useful quantity.
The best summary is therefore not that New Zealand began rearming in 1939. Rather, by 1939, New Zealand’s rearmament was already underway, but it remained limited, fragmented, and too slow to meet the scale of the coming war.
The Logistics Baseline, 1937 to April 1939
The pre-war NZAOC establishment shows how small the support organisation still was. In 1937, the NZAOC military establishment numbered 44 personnel. This was supported by a civilian establishment of 122, giving a combined NZAOC establishment of 166. That establishment covered the Main Ordnance Depot, the Ordnance Workshop at Trentham, Northern and Southern Command elements, clerical staff, storemen, armourers, artificers, saddlers, tent repairers, tradesmen, caretakers, night-watchmen, and other support personnel.[11]
The Director of Ordnance Services had already recognised the danger of a small establishment. In March 1937, when commenting on proposed NZAOC military and civilian establishments, he noted that the figures assumed that the existing organisation and establishment of the Territorial Force would remain largely unchanged, and that no major increase beyond existing schemes for coast and air defence was contemplated. He warned that if any great development of mechanisation took place during the next five years, the establishment of the Ordnance Workshops would probably prove inadequate.
The April 1939 figures add an important intermediate point. They show that, immediately before the outbreak of war, the uniformed Ordnance specialist base remained extremely small. The return listed only 38 WO1s and other ranks across the Armourer, Armament, and Ammunition sections at the Main Ordnance Depot, Waikato Camp and Burnham Camp. This figure did not include the 10 NZAOC officers and should not be read as the entire Ordnance workforce. Ordnance stores were still substantially staffed by civilians, while military personnel were concentrated in specialist armourer, armament, and ammunition duties.[12]

Even with those qualifications, the figure is revealing. On the eve of war, the uniformed technical core available to support weapons, ammunition, and armament stores was still modest. The system relied on a combination of a small uniformed technical cadre and a civilian stores workforce. This arrangement could sustain a peacetime Army, but it was not designed for mass mobilisation, large-scale mechanisation, major ammunition expansion, or the rapid receipt of modern weapons and technical equipment from overseas.
This civilian staffing was not accidental. It was the result of an economic decision taken during the Depression. On 14 July 1930, all ranks of the Corps, except officers, armament artificers, and armourers, were transferred to the civil service. The clerical and stores sections of the Corps were demilitarised, placed on a civilian basis, graded by the Public Service Commissioner, and subjected to reduced pay rates. This helps explain why the April 1939 uniformed Ordnance figures appear so small. They do not show the whole NZAOC labour force, but the remaining uniformed technical cadre within a system where much of the stores and clerical work had been civilianised.[13]
The question of whether NZAOC staff should again wear uniform became a live issue during the war. A January 1940 letter to the Prime Minister argued that NZAOC men had once worn uniform, were serving in the war, and were “the backbone” of the system. A further letter complained that men at Trentham doing NZAOC work were not provided with a uniform or rank, despite working for King and country. By 30 June 1941, this question had not been fully resolved. It would take the increasing pressure of wartime expansion to force a final decision.[14]
The NZASC and the Interwar Logistics Base
The New Zealand Army Service Corps provides an important companion to the NZAOC story. If the NZAOC showed the difficulty of storing, maintaining, inspecting, and issuing equipment, the NZASC showed the parallel challenge of moving and sustaining the force. In the interwar period, the NZASC remained small, underfunded, and still partly shaped by horse transport, but it was not inactive. Its officers and soldiers continued to train, revise establishments, experiment with motor transport, and preserve a body of practical knowledge in supply and transport that would become vital after 1939.
At the centre of this continuity was Stanley Herbert Crump. His First World War experience had been directly relevant to the problems New Zealand would face again in the Second World War. He had served in Egypt and Palestine with the New Zealand Mounted Rifles Brigade and the Mounted ANZAC Divisional Train, gaining experience in supply, transport, movement, and sustainment in difficult country. Senior officers praised his resourcefulness, reliability, and ability to keep formations supplied despite heat, dust, mud, poor roads, and long marches. That experience mattered because the Middle East would again become the main theatre in which New Zealand’s Army Service Corps had to prove itself.[15]
After the war, Crump remained in the Regular Force and became closely associated with the Permanent Army Service Corps. By 1923 he was Officer Commanding the PASC, while also fulfilling duties connected with supplies, transport, and Quartermaster-General functions at General Headquarters. The establishment of a permanent ASC element had been considered carefully after the First World War. In 1919, Lieutenant Colonel William Avery argued that such a corps was needed to control mechanical transport equipment, provide supply and transport services in the military districts, instruct Territorial ASC units, provide trained officers for mobilisation, and ensure proper care of ASC vehicles and equipment.[16]
This was significant. It shows that the interwar ASC was not merely a dormant remnant of the First World War. Its permanent cadre existed to preserve knowledge, train the Territorial ASC, maintain equipment, and provide the nucleus for mobilisation. The problem was that this nucleus remained small and had to operate within the same financial and political constraints that affected the rest of the Army.

The ASC’s development also illustrates the uneven transition from horse to motor transport. As late as the mid-1930s, each military district still retained a section dedicated to horse transport and only one section for Motor Transport. The horse had not yet disappeared from New Zealand military logistics. Nevertheless, the direction of travel was clear. In 1937, Major-General J. E. Duigan reported that successful transportation in war had always depended on the efficient use of civil resources and that the modern Army was now dependent on the motor industry for its mobility. He also noted that using motor transport instead of horse-drawn vehicles for unit transport had been successfully tried and would be adopted in the future.[17]
The change was gradual rather than dramatic. New Zealand moved more slowly than Australia and Britain in mechanising its supply and transport services. Financial constraints limited the number of military vehicles that could be acquired in peacetime, and Territorial ASC units continued to train with limited equipment. Yet the evidence shows steady adaptation. By 1938, despite the small number of trucks and lorries physically owned by the New Zealand Military Forces, Territorial ASC units were conducting increasingly motorised convoys and drills. One South Island exercise in August 1938 was described as the largest motorised military convoy assembled in the South Island, although its total strength was still modest: six lorries, four vans, four cars, three motorcycles, and accompanying army kitchens and trailers.
This matters for understanding 1939. When the Second World War began, New Zealand did not have a fully motorised ASC ready to support a modern division. The official history of the Petrol Company later observed that in 1919 the Army Service Corps could muster only twenty motor trucks and cars, and that by 1939 New Zealand possessed only eighty-six military motor vehicles of all kinds. It also noted that after compulsory military training was abolished in 1930, the NZASC was reduced from 457 all ranks to 287, and by 1939 had dwindled to 168, mostly Territorials, divided among the three military commands. Each command had a composite ASC company that undertook all ASC duties and still used horse transport. The judgement was blunt: when the Second World War broke out, New Zealand had no unit specially formed or trained to supply a modern fighting force with petrol, oil, and lubricants, or to service its vehicles.[18]
That statement should not be read as meaning that there was no preparation. Rather, it captures the difference between a trained nucleus and a fully developed wartime capability. The interwar NZASC had preserved expertise, trained Territorial personnel, experimented with motorisation, and provided officers and soldiers with practical knowledge of supply and transport. What it lacked was scale. It did not possess enough vehicles, specialist units, trained manpower, or mechanical depth to support a modern division without rapid expansion.
The mobilisation of the ASC in 1939, therefore, paralleled the NZAOC problem. The Supply Company official history recorded that, although the unit’s operations were based on motor transport, there were only ten training vehicles in camp, two of them artillery tractors, and those few vehicles had to be shared with 4 Reserve Mechanical Transport Company. Petrol Company faced similar limitations, receiving a mixed collection of civilian-style vehicles, including butchers’ vans, brewery wagons, and a small number of heavier trucks, to provide at least some motor transport training before embarkation.[19]
The NZASC also contributed to the broader administrative and welfare dimensions of mobilisation. In October 1939, public concern over soldiers’ nutrition led to the creation of a committee to examine military food, with Crump serving in his role as Quartermaster-General. The committee considered the diet of troops in New Zealand camps and drew on advice from the Medical Research Council. This was another reminder that logistics was not confined to vehicles and supplies. It also included feeding, nutrition, camp administration, and soldiers’ health and morale.[20]
The interwar NZASC therefore reinforces the central argument of this article. New Zealand was not idle before 1939, but neither was it ready in the full sense required by modern war. Like the NZAOC, the ASC had preserved a small professional core and had begun adapting to mechanisation, but it remained constrained by limited money, reduced establishments, horse-era habits, and a shortage of vehicles. By 1939, it possessed experience and intent, but not the scale, equipment, or depth required to sustain a modern expeditionary force without urgent wartime expansion.
Weapons, Ammunition, and the 1939 Capability Gap
The same pattern was visible in weapons and ammunition. The 1939 figures reveal the practical limits of New Zealand’s defence position at the outbreak of war. In many areas, requirements were clear, but holdings were low, incomplete, or still represented by orders rather than equipment physically in hand. More importantly, weapons, ammunition, transport, and storage are inseparable. A gun without ammunition was not a capability. Ammunition without safe storage, transport, inspection, and trained personnel was not a capability either. Nor could equipment become operational capability unless the Army possessed the supply and transport system required to move it, feed it, fuel it, and keep it in use.
The most obvious example was anti-tank defence. The requirement for 2-pounder anti-tank guns was recorded as ninety weapons, but only sixteen were shown as on order. This left a balance of seventy-four still required. The shortage was not simply numerical. Anti-tank warfare had become one of the defining problems of modern land operations, and the 2-pounder represented New Zealand’s intended move towards a more credible anti-armour capability. Yet in 1939, the Army had only on order a fraction of what it believed it required.[21]
Anti-tank ammunition was even more fragile. The 2-pounder anti-tank gun had a war reserve requirement, but the 1939 schedule showed no stock in hand, and the reserve was dependent on future delivery. This meant that anti-tank capability was doubly constrained, by the limited number of guns and by the uncertain arrival of ammunition.
The position with light automatic weapons was similarly revealing. Against a requirement of 1,245 light machine guns, only forty Brens were available in 1939, with 312 on order. The Bren was central to modern infantry firepower. However, its limited availability meant that much of the force still depended on older Hotchkiss and Lewis light machine guns while awaiting more modern equipment.

Rifles presented a different type of problem. The requirement for .303 rifles was recorded at 22,470, while 73,481 were shown as available or on order. The rifle issue was therefore less about absolute absence and more about mobilisation, distribution, training, reinforcement, and the demands of an expanding force.
Field artillery was also a mixed picture. The older 18-pounder remained important, with fifty-four recorded. There were also eighteen 4.5-inch howitzers, four 60-pounders, twelve 6-inch howitzers, and smaller numbers of other field and coast-defence weapons. These provided a basis for training and mobilisation, but they also reflected the persistence of First World War-era equipment in New Zealand service. The modern 25-pounder appeared in planning, with a requirement for ninety guns, but remained an aspirational transformation for the Army’s field artillery holdings.
Ammunition holdings reveal the same unevenness. For the 18-pounder, the war reserve requirement was 56,700 rounds. The 1939 schedule showed 14,696 rounds in stock and 5,500 on order, for a total of 20,196 rounds in sight. This was well short of the desired reserve. A later memorandum of 22 September 1939 recorded urgent orders for a further 36,000 rounds, 15,000 from India and 21,000 from the United Kingdom.[22]
For the 4.5-inch howitzer, the requirement was 18,900 rounds. The same schedule showed 3,389 rounds in stock and 5,539 on order, for a total of 8,928 rounds in sight. The September 1939 memorandum then recorded urgent orders for a further 10,000 rounds, 7,000 from India and 3,000 from the United Kingdom.
The 25-pounder was different. It represented the desired future of field artillery, but in 1939, it was still more of a requirement than a practical holding for New Zealand. This is important because it highlights the gap between the intent to modernise and the physical delivery. The Army knew what it needed and was attempting to align with British developments. Still, global demand, British production priorities, shipping, and local infrastructure all slowed the conversion of requirement into capability.
Small arms ammunition was held in much larger quantities, but even here, the figures show an Army working towards readiness rather than resting on abundance. For .303 ammunition, the schedule recorded 22,629,121 rounds in stock, 19,000,000 on order, and a total in sight of 45,629,121 rounds, against a recommended war reserve of 48,000,000 rounds. It also noted an estimated annual training turnover of 5,000,000 rounds.

1939 Ammunition Readiness Snapshot
By 30 June 1941, the Army’s ammunition position had improved in some areas, but it remained uneven. The essential point is not that New Zealand had solved its ammunition problem by mid-1941. It had not. Rather, the Army had recognised the scale of the deficiency, placed urgent orders, and begun the difficult process of aligning ammunition reserves, storage, transport, inspection, and issue systems with the requirements of a modernising force.[23]
Urgent Orders and the Shift from Peace to War
The September 1939 memorandum is especially useful because it shows how quickly assumptions changed once war approached. It stated that earlier estimates had been prepared on a peacetime basis, but that urgent orders had since been placed for ammunition and field artillery tractor equipment.
The urgent ammunition orders were substantial. The United Kingdom orders were estimated at £79,000, equivalent to approximately NZ$10.5 million in 2026, while the orders placed in India were estimated at £80,641, approximately NZ$10.7 million in 2026. Orders were also placed for 100 Marmon-Herrington adapters fitted to vehicles at £74,000, approximately NZ$9.8 million in 2026.[24]
These figures matter because they show that New Zealand’s early mobilisation was not simply administrative. It involved real financial commitment, rapid overseas procurement, and the practical effort to turn older or impressed vehicles into artillery tractors.
The Marmon-Herrington adapter order is especially useful because it demonstrates the practical character of early wartime logistics. New Zealand was not merely buying guns and ammunition. It was also trying to create the transport and traction capacity needed to move artillery in a more mobile war.[25] This was a small but telling example of a wider problem. Weapons required ammunition, but they also required vehicles, tractors, spares, workshops, mechanics, drivers, and storage.
Old Weapons, New War
One of the most important themes in the 1937 to 30 June 1941 evidence is the coexistence of old and new. The 18-pounder, 4.5-inch howitzer, 60-pounder, 6-inch howitzer, Lewis guns, Hotchkiss guns and older coast-defence systems remained part of the Army’s practical inventory. At the same time, Bren guns, Boys anti-tank rifles, 3-inch mortars, 2-pounder equipment, wireless sets, modern range-finding gear, and searchlight equipment were being sought or introduced.
This should not be dismissed as mere backwardness. In 1939 and 1940, New Zealand had to train, mobilise, defend ports and key installations, support overseas commitments, and prepare for possible attack, all at once. Under those conditions, an older gun with ammunition, trained detachments, and an existing maintenance base was often more useful than a modern gun that had not yet arrived.
The NZAOC problem was therefore not simply one of obtaining new weapons. It was also one of keeping older weapons in service, sourcing ammunition for multiple calibres, accounting for mixed holdings, maintaining spares, and supporting training with equipment that was often already nearing obsolescence.
This was integrated logistics in practice. The issue was never just, “how many guns?” It was also, “what ammunition?”, “what sights?”, “what carriages?”, “what spares?”, “what trained maintainers?”, “what storage?”, and “what risk?”
Motorisation Before 30 June 1941
The same pattern was visible in motor transport. Modern war required not only guns, rifles, mortars, ammunition, and wireless equipment, but vehicles, trailers, tyres, tools, spare parts, workshops, mechanics, drivers, vehicle parks, recovery arrangements, fuel, and accounting systems. In 1939, the NZAOC remained largely shaped around clothing, camp equipment, ammunition, arms, and accessories, while the NZASC had only limited vehicle holdings and an uneven motorisation base.
Before the war, the Army possessed only a small motor vehicle fleet. One later account records that by September 1939, the Army owned 62 vehicles, while the MT Stores history records the pre-war Army vehicle holdings as 56 vehicles. Another ASC-focused account reported that the total number of military motor vehicles was 86 by 1939. The differences are not decisive for the argument. All point to the same conclusion: the pre-war Army was not yet organised for the motor transport demands of a rapidly expanding wartime force.
This exposed another limit in the pre-war support system. The Army was trying to align itself with British modern military practice, which by 1939 was increasingly motorised. Some of this thinking had already reached New Zealand through equipment such as Bren guns and Universal Carriers, as well as limited experiments in mechanisation. However, interwar defence policy, financial constraints, and the small size of the pre-war logistics organisations meant that New Zealand did not possess a support structure comparable to that of the Royal Army Ordnance Corps or the Royal Army Service Corps in Britain. The NZAOC had limited experience supporting Mechanical Transport at scale, while the NZASC had preserved knowledge of supply and transport but lacked the vehicles, manpower, and specialist units needed for a modern expeditionary division.
The response was organisational as much as material. Recognising that the Army’s motor fleet would expand beyond what the existing structures could easily absorb, the Quartermaster-General established a separate Mechanical Transport Branch. This allowed the NZAOC to concentrate on its core responsibilities, while the MT Branch managed and maintained the growing fleet of purchased and impressed vehicles. The branch drew heavily on the expertise of the New Zealand motor industry, with many staff recruited directly into the New Zealand Temporary Staff. In the early years of the war, the Army relied heavily on civilian vehicles impressed into service, and on existing stocks from motor manufacturers and dealerships, which were purchased to provide MT spares.[26]
For the period to 30 June 1941, the important point is not the later scale of the MT organisation, but the fact that motorisation had already exposed a structural weakness. The Army could not simply acquire vehicles and expect them to produce mobility. Each vehicle created a requirement for drivers, fitters, mechanics, tyres, tools, spares, workshops, recovery, fuel, records, and stores control. Motorisation, therefore, added another layer to the same problem faced by the NZAOC and the NZASC more broadly. New capability demanded a larger and more specialised support system.
Infrastructure, the Hidden Cost of Rearmament
The 1939 to 1940 Mackesy-related papers provide clear evidence that planners understood rearmament as both an infrastructure and an equipment problem. The follow-up work divided the programme into three parts: reserve ammunition for weapons already possessed or ordered, modern fighting and technical equipment for the Territorial Force, and the magazine, garage, and storage accommodation needed to house the equipment and ammunition covered by the first two parts. It also recommended that, if the proposals were approved in principle, an immediate start be made on local expenditure for accommodation.[27]
This is one of the most important points in the article. It shows that New Zealand’s early war preparation was not just a matter of ordering guns, rifles, mortars, vehicles, and ammunition. Those items had to be received, protected, stored, maintained, issued, moved, and accounted for.
Trentham Camp, November 1941. National Archives, AAOD,W3273, Box 19, Record WDO 9811, R18059582
The proposed infrastructure programme was substantial:
Infrastructure item
1939 estimate
Indicative 2026 NZD
Additional magazines for ammunition
£126,000
NZ$16.7 million
Garage accommodation, 440 vehicles at £160 each
£70,400
NZ$9.3 million
Storage accommodation
£100,000
NZ$13.2 million
Total accommodation
£296,400
NZ$39.2 million
The accommodation programme is significant because it demonstrates that rearmament created second-order demands. More ammunition requires more magazines. More vehicles require garage accommodation. More technical equipment requires storage. A larger Army needed not only weapons, but a larger physical logistics system.
By 30 June 1941, many of these requirements had been recognised, but the full expansion of depots, magazines, workshops, Mechanical Transport stores, supply systems, and inspection systems still lay ahead. The point is not that New Zealand had solved the logistics infrastructure problem by mid-1941, but that it had begun to define it.
Later wartime construction would reveal the full scale of the problem through a nationwide magazine construction programme. But for this article, the crucial point is that the requirement for magazines, garages, and storage had already been recognised before 30 June 1941. Ammunition did not merely appear in an inventory. It required land, roads, traverses, buildings, guard accommodation, repair workshops, water, electricity, camouflage, rail access, safety distances, and trained staff.[28]
Industry, Inspection, and the Home Logistics Base
New Zealand’s early wartime logistics system also had to prepare for the output of local industry. Large quantities of stores were still expected from overseas, but domestic production was becoming increasingly important. Local industry would go on to produce or assemble Universal Carriers, small-arms ammunition, mortars, mortar bombs, shell fuzes, gunnery instruments, Sten guns, wireless equipment, military clothing, boots, pumps, petrol tanks, grenades, road-construction equipment, water bottles, and other stores.
Article from Newzeaford News, November 1941
This industrial effort did not reduce NZAOC or NZASC work. It increased it. Every locally produced item had to be inspected, proved where necessary, received, stored, packaged, maintained, accounted for, issued, and, in many cases, transported to camps, depots, ports, or units. New Zealand industry became part of the Army logistics support system, but military logistics organisations remained the mechanism that turned industrial output into usable military stores.
By 30 June 1941, the later full system had not yet matured, but the requirement was already apparent. Rearmament was neither simply an industrial nor a military problem. It was a combined logistics problem linking government, industry, inspection, transport, storage, accounting, and issue.
The Capital Cost of Readiness
The overall 1939 programme was costed in three main parts:[29]
Programme component
1939 estimate
Indicative 2026 NZD
Part A, reserve ammunition for existing equipment
£276,971
NZ$36.7 million
Part B, modern fighting equipment
£1,898,753
NZ$251.4 million
Part C, magazine, garage, and storage accommodation
£296,400
NZ$39.2 million
Total programme
£2,472,124
NZ$327.3 million
The scale of these sums is important. The 1939 programme was not a minor tidy-up of existing stocks. It was a major capital proposal to modernise the Territorial Force, build ammunition reserves, and provide the physical infrastructure needed to sustain the new equipment.
The fact that Part C alone equates to roughly NZ$39 million in 2026 terms underlines how much of rearmament lies outside the weapons themselves. Magazines, garages, stores, workshops, handling arrangements, supply systems, transport arrangements, and accounting systems were not secondary details. They were the practical foundation of readiness.
When the manpower, industrial, NZAOC, NZASC, and MT evidence is added, the point becomes even stronger. A modern Army could not be built merely by approving equipment tables or placing orders overseas. The Army needed trained personnel to staff depots, workshops, ammunition sections, inspection organisations, mechanical transport branches, supply and transport branches, industrial inspection systems, catering arrangements, and administrative control systems. The cost of readiness was therefore financial, physical, organisational, industrial, and human.
Preparation Before Expansion
By 30 June 1941, New Zealand had not solved its logistics problem, but it had begun to define it. Rearmament was underway, urgent overseas orders had been placed, and selected holdings of rifles, Bren guns, mortars, grenades, ammunition, and coast-defence stores had improved. Yet readiness remained uneven. Modern anti-aircraft equipment was still limited; the 25-pounder had not yet fully replaced older field artillery, anti-tank equipment remained short, and ammunition reserves were still vulnerable to movement, training consumption, redistribution, and delayed overseas supply.
The central issue was balance. The Army was not simply acquiring stores; it was trying to build a force in which weapons, ammunition, transport, workshops, depots, trained personnel, inspection systems, and infrastructure developed together. The NZAOC, NZASC, Mechanical Transport organisation, and Quartermaster-General’s Branch each carried part of that burden. Together, they show that rearmament was never just a weapons programme. It was the beginning of a national logistics mobilisation.
By mid-1941, the foundations had been laid, but the system remained thin. The larger expansion still lay ahead, and it would test every part of the logistics structure that had been preserved, improvised, or rebuilt during the late 1930s.
Lessons for Contemporary New Zealand Military Logisticians
The 1937 to 30 June 1941 experience offers useful lessons for contemporary New Zealand military logisticians, but they should be handled with care. The purpose is not to judge the interwar Army with the benefit of hindsight. The officers, soldiers, public servants, and civilian workers of the period operated within severe financial, political, industrial, and imperial constraints. The value of the case study lies in demonstrating how a small logistics system behaves when it must expand rapidly under strategic pressure.
The first lesson is that preparedness cannot be measured by equipment holdings alone. Weapons, vehicles, radios, ammunition, fuel, rations, and technical stores only become military capability when the supporting system exists to receive, inspect, store, issue, maintain, repair, move, feed, fuel, and account for them. The pre-war Army had identified many of its equipment deficiencies, and orders for modern stores were already being placed. The limiting factor was often the depth of the logistics system beneath those orders.
The second lesson is that small peacetime compromises can become normalised. The interwar Army adapted to reduced establishments, civilianised stores support, limited transport, old weapons, small ammunition reserves, horse-era supply structures, and inadequate infrastructure. These arrangements were understandable in the circumstances, but over time, they became the accepted baseline. A workaround that keeps a system functioning in peacetime may conceal a weakness that becomes critical during mobilisation or crisis.
The third lesson is that logistics manpower is a capability. The small pre-war NZAOC cadre, the civilianised stores workforce, the tiny April 1939 uniformed technical establishment, and the reduced NZASC all show that trained logisticians cannot be created instantly. Storemen, supply personnel, cooks, petrol personnel, drivers, ammunition personnel, armourers, artificers, mechanics, clerks, inspectors, transport staff, and technical specialists all require experience and continuity. Modern systems may be more digital, but they still depend on trained people who understand both the process and the operational consequences.
The fourth lesson is that modernisation creates second-order demands. In the 1930s and 1940s, the expansion of motor transport created requirements for workshops, spares, tyres, tools, mechanics, vehicle depots, fuel arrangements, drivers, traffic control, convoy procedures, and MT stores. The same principle applies today. New platforms, digital systems, protected mobility, sensors, autonomous systems, or deployed networks all generate support burdens that may be larger and more complex than the original acquisition suggests.
The final lesson is that readiness is cumulative. The Army could expand after 1939 because some framework already existed, but that framework was thin. Depots, workshops, magazines, transport systems, supply arrangements, catering systems, inspection arrangements, and trained personnel all had to grow under pressure. The enduring lesson is that logistics readiness must be built before the crisis. Once mobilisation begins, the logistics system is no longer preparing for war. It is already part of the fight.
Conclusion
By 30 June 1941, New Zealand had not reached logistical abundance, but it had moved beyond passive austerity. Rearmament was underway, urgent orders had been placed, ammunition deficiencies were being addressed, infrastructure requirements had been costed, and the weaknesses of the small pre-war NZAOC, NZASC, and Mechanical Transport systems were increasingly visible.
The evidence from 1937 to mid-1941 changes the way New Zealand’s early wartime preparation should be understood. Rearmament did not begin suddenly in 1939, nor was the Army intellectually dormant before the war. Requisitions for ammunition, explosives, modern weapons, signalling stores, coast-defence equipment, anti-gas equipment, tentage, and technical stores show that modernisation was already underway. The NZASC story points in the same direction. Its interwar training, permanent cadre, Territorial structure, and gradual shift from horse to motor transport show that preparation existed but remained limited, uneven, and short of the scale required for modern war.
The deeper weakness was logistical. Weapons required ammunition, ammunition required magazines, vehicles required workshops and spares, local production required inspection, and all of it required trained personnel, records, transport, storage, supply, feeding, fuel, and administrative control. The growth from a 1937 NZAOC establishment of 44 military personnel and 122 civilians, through an April 1939 technical establishment of 10 officers and 38 WO1s and other ranks, together with the reduced and lightly motorised NZASC, shows that this was never only a weapons programme. It was a logistics mobilisation.
That mobilisation was still incomplete by mid-1941. The Army had preserved important professional knowledge, retained a small regular and Territorial logistics base, and begun to identify the infrastructure and manpower required for expansion. Yet it still lacked the depth needed for a fully modern force. The normalisation of interwar constraint had left New Zealand with a system that could begin mobilisation but not expand without strain.
The story of 1937 to 30 June 1941 is therefore not one of simple failure or effortless mobilisation. It is the story of an Army, and its Ordnance, Army Service Corps, Mechanical Transport, and Quartermaster-General’s services, attempting to turn limited interwar resources into wartime capability. By mid-1941, that transition was incomplete, but its direction was unmistakable: readiness depended as much on logistics, manpower, industry, motor transport, storage, inspection, supply, transport, fuel, feeding, and infrastructure as it did on guns and ammunition.

Modernisation, Mobilisation, and Early Integrated Logistics Thinking in the New Zealand Army
In May 1939, Major-General P. J. Mackesy, C.B., D.S.O., M.C., submitted his report on the Military Forces of New Zealand. Prepared after a short but intensive inspection, the report has not acquired the same place in New Zealand defence history as the earlier assessments associated with Scratchley, Jervois, Fox, Babington, or Kitchener. Those reports, and the reforms or controversies that followed them, are comparatively well recorded. Mackesy’s report, by contrast, remains less visible, despite being written only months before the outbreak of the Second World War and despite its clear relevance to New Zealand’s final pre-war military preparations.
Read in isolation, Mackesy’s report appears to belong to the pre-war world of Imperial defence planning, Territorial Force mobilisation, coast defence, ammunition reserves, mechanisation, and ordnance services. Yet when considered against the principles of modern capability management and Integrated Logistics Support (ILS), it reveals something more enduring. Mackesy did not create integrated logistics thinking in the New Zealand Army, nor did he use the terminology of modern ILS. Rather, his report provides an early and clear example of the same underlying logic, that equipment, ammunition, personnel, training, storage, mobilisation, reserves, finance, procurement lead times, accommodation, and technical support had to be treated as connected parts of one military capability system.
This distinction matters. Mackesy was not arriving to modernise an entirely dormant Army. By 1939, the New Zealand Army was already in the throes of modernisation. Modern equipment had been ordered, some had arrived, and the Army staff were attempting to keep pace with contemporary British doctrine, mechanisation, mobilisation planning, and the implications of modern weapons. The problem was not total inactivity, but incompleteness. Mackesy’s significance lay in reinforcing an existing direction of travel, exposing the remaining gaps, and turning modernisation from a matter of equipment acquisition into a whole-force capability problem.
The later expansion of the New Zealand Army Ordnance Corps (NZAOC) demonstrates why that distinction matters. By 1942, the Ordnance Depot and Ordnance Workshops establishments had both been expanded and treated as Dominion establishments. In other words, manpower was managed nationally across New Zealand rather than permanently assigned to a single depot or workshop. The depot system provided the national machinery for receipt, accounting, storage, issue, and distribution, while the workshop system provided the technical capacity for inspection, repair, modification, maintenance, and specialist support. This wartime growth shows that the support problem Mackesy identified was not theoretical. Once modern equipment, ammunition, vehicles, and technical stores entered service, the Army had to build the support organisation beneath them. In modern ILS terms, the Mission System forced the Support System to expand.
The modern NZDF ILS Capability Management Handbook describes ILS as critical to cost-effective planning, integration, optimisation of through-life support, and the sustainment of safe capability. It links ILS to affordability, Whole-of-Life Cost awareness, preparedness, availability, and Defence resilience. Mackesy was not applying that formal framework in 1939, but his method, and the Army’s subsequent treatment of Recommendations 42 and 43, anticipated many of its principles.
This article, therefore, does not argue that Mackesy invented modern ILS, nor that his report can be used as a direct measure against contemporary logistics practice. Rather, it argues that Mackesy’s report provides a historically useful example of integrated logistics thinking before the term existed. It also offers contemporary logisticians a professional reminder, not a judgment, that military capability is only credible when the support system beneath it is understood, resourced, tested, and sustained.
Put simply, Mackesy was asking whether the Army’s equipment, people, stores, transport, workshops, training and facilities could work together as a real wartime system.
For readers unfamiliar with modern logistics terminology, the central idea is simple. A military capability is more than the equipment listed on an inventory. It also depends on the people trained to use it, the ammunition and spares held for it, the facilities that store and maintain it, the transport that moves it, and the systems that account for and sustain it. Modern ILS gives that idea a formal structure. Mackesy’s report shows that the same logic was already evident in the New Zealand Army’s planning in 1939.
Major-General P. J. Mackesy and the circumstances of the report
Major-General Pierse Joseph “Pat” Mackesy, C.B., D.S.O., M.C., was a senior British Army officer of the Royal Engineers and a decorated veteran of the First World War. He was commissioned into the Royal Engineers in 1902, served in a range of operational and staff appointments, and by the late 1930s was an experienced Imperial officer with a professional background in command, training, mobilisation, and military organisation. His standing mattered because he was not a casual visitor or political commentator, but a senior officer able to assess New Zealand’s forces against contemporary British military practice.

His report on the Military Forces of New Zealand was prepared at the request of His Majesty’s Government in New Zealand after the Pacific Defence Conference. The United Kingdom authorities made his services available to the New Zealand Government for a few weeks, and he began his investigations in Auckland on Monday, 1 May 1939. By 22 May 1939, he had submitted his report to Army Headquarters, Wellington.[1]
Mackesy was careful to acknowledge the limits of his inquiry. He stated that it was impossible for one individual, in only three weeks, to investigate in detail all the activities and points of importance connected with the military forces of a country the size of New Zealand. Nevertheless, he had sought to obtain a fair and thorough general view of the problems involved. He also emphasised that his recommendations would require careful investigation before any action could be taken.[2]
He also made clear that the report was not an official British Government or War Office directive. The opinions, views, and recommendations were his own, and he alone was responsible for them. This gave the report a direct and candid tone. Mackesy told the Prime Minister that he understood plain and honest words were required, but he also stressed that where he criticised what he found, he did not intend criticism of individuals or groups. His purpose was to look at conditions as they existed and suggest how they could reasonably be improved.[3]
The timing was significant. The report was written only months before the outbreak of the Second World War, at a moment when the deteriorating international situation was testing New Zealand’s defence assumptions. Mackesy’s task was therefore not academic. He was examining whether the New Zealand Army, particularly its Territorial Force, mobilisation arrangements, equipment, ammunition reserves, training system, accommodation, and ordnance services, could meet the demands likely to be placed upon it in war.
Mackesy in the tradition of British defence inspection reports
Mackesy’s 1939 report also sits within a longer tradition of British officers inspecting, advising upon, and reporting on New Zealand’s defences. He was not the first senior Imperial or British officer to examine the country’s military arrangements, nor was his report an isolated event. From the late nineteenth century onward, New Zealand had repeatedly looked to British professional military expertise to assess its defence organisation, coastal protection, volunteer forces, mobilisation arrangements, and military efficiency.
Among the better-known examples were Major-General Sir Peter Henry Scratchley and Major-General Sir William Francis Drummond Jervois, whose work on colonial defence helped shape the port and coastal defence systems of Australia and New Zealand in the late nineteenth century.[4]
The pattern continued with Lieutenant-Colonel Francis John Fox, appointed Commandant of the New Zealand Permanent Militia in 1892. Fox inspected the Volunteer Force and produced a highly critical 1893 report, which caused a public and political stir for its uncompromising comments on the force’s condition and officers’ fitness for command.[5] Major-General Sir James Melville Babington, Commandant of the New Zealand Defence Forces from 1902, also produced formal reports on the Defence Forces of New Zealand.[6] Field Marshal Horatio Herbert Kitchener, 1st Earl Kitchener, later inspected New Zealand’s forces during his 1910 tour, contributing to the defence reform debate around compulsory military training and the wider reorganisation of Dominion defence.[7]
These earlier inspections and reports are reasonably well recorded in New Zealand defence history. Their recommendations, political reception, and subsequent reforms are traceable through parliamentary papers, newspapers, biographies, and later historical writing.
Mackesy’s report is different. Although it was prepared at a critical moment, only months before the outbreak of the Second World War, it appears to have attracted comparatively little sustained attention. The surviving archival record confirms that Mackesy submitted a formal report on the Military Forces of New Zealand on 22 May 1939, and that a later file addressed Recommendations 42 and 43, concerning modern equipment and ammunition reserves. Yet compared with Scratchley, Jervois, Fox, Babington, and Kitchener, there is a noticeable dearth of readily accessible secondary discussion on Mackesy’s findings and their subsequent influence. One possible reason is timing: war intervened almost immediately, shifting attention from broad reform to urgent mobilisation. Another may lie in Mackesy’s later wartime reputation. Within a year of advising New Zealand, Mackesy was associated with the controversial Norwegian campaign and was recalled after his handling of the Narvik operation enraged Prime Minister Winston Churchill. According to later accounts, Mackesy refused to commit his troops to what he considered “the sheer bloody murder” of an “arctic Gallipoli”, prompting Churchillian accusations of “feebleness and downright cowardice”. Although he avoided court-martial, Mackesy never again held field command.[8] While there is no clear evidence that New Zealand consciously suppressed or distanced itself from Mackesy’s report for that reason, his subsequent fall from favour may have made him a less convenient figure to acknowledge publicly.
That relative silence is significant. Mackesy’s report came at the hinge point between peacetime economy and wartime mobilisation. Unlike some earlier reports, it was not followed by a long period of public debate or gradual reform. The declaration of war rapidly overshadowed the broader recommendations, and attention appears to have narrowed to the most immediately actionable parts of the report, especially Recommendations 42 and 43 on modern equipment and ammunition reserves.[9] The follow-up papers show that these recommendations were implemented as a programme covering ammunition reserves, modern fighting and technical equipment, and the magazine, garage, and storage accommodation required to support them.[10]
For that reason, Mackesy’s report deserves to be recovered and re-examined. It belongs in the same broad tradition as Scratchley, Jervois, Fox, Babington, and Kitchener, but its significance lies in its timing. It was a final pre-war external assessment of the New Zealand Army before the demands of the Second World War forced theory into action. Its relative neglect has obscured the degree to which the Army’s wartime mobilisation priorities, especially modern equipment, ammunition reserves, mechanisation, and storage, were already being framed through a recognisably integrated logistics lens.
A report on the Army as a system
The structure of Mackesy’s report is revealing. Its table of contents moved beyond narrow questions of manpower or equipment and examined Regular Forces, the Territorial Force, the Special Reserve, Cadet Units, training, accommodation, mobilisation preparations, mechanisation, modern fighting equipment, ammunition, trained reserves, publicity, ordnance services, and financial administration.[11]
This breadth is important. In modern capability language, Mackesy was examining a range of inputs that would now be recognised across the PRICIE construct. The NZDF ILS Handbook describes PRICIE as the fundamental inputs to capability, covering Personnel, Research and development, Infrastructure and organisation, Concepts, doctrine and collective training, Information technology, and Equipment, logistics and resources.[12]
Mackesy did not use that vocabulary, but his report covered many of the same areas. He did not treat modern equipment as a stand-alone answer. He saw that equipment without trained personnel, ammunition, storage, transport, maintenance, and mobilisation arrangements did not constitute real military capability.
Mackesy’s central concern was that New Zealand’s military arrangements gave the appearance of a force without necessarily providing the substance of one. His analysis was rooted in a simple but enduring question:
Could the New Zealand Army actually perform the tasks expected of it in war?
He concluded that, under existing conditions, it could not do so with confidence.
Mission System and Support System
The modern NZDF ILS Handbook describes capability from an ILS perspective as the combination of a Mission System and a Support System. The Mission System is the part of the capability that directly performs the operational function, such as aircraft, ships, armour, communications, or, in Mackesy’s case, modern weapons and vehicles. The Support System is the totality of support infrastructure, resources, services, people, processes, and systems that enable the Mission System to be supported and operational objectives to be achieved.[13]
This distinction helps explain why Mackesy’s report remains relevant. His concern was not only that the New Zealand Army lacked sufficient modern Mission Systems, such as contemporary weapons, vehicles, and technical equipment, but also that the supporting system around them was incomplete. Ammunition reserves, trained personnel, mobilisation depth, magazines, garages, stores, training arrangements, and sources of supply all had to be provided if modernisation was to become a real capability.
In modern ILS terms, Mackesy was not simply asking, “What equipment does the Army need?” He was asking, “What system of support is required to make that equipment usable, sustainable, and available in war?”
The modern ILS view of capability as a Mission System supported by an integrated Support System. Although Mackesy did not use this terminology in 1939, his report considered many of the same elements, including personnel, training, equipment, ammunition, reserves, storage, transport, facilities, and supply.
Not modernisation from a standing start
It is important not to overstate Mackesy’s role as though he arrived in New Zealand to instruct an entirely dormant Army to modernise from scratch. By 1939, the New Zealand Army was already in the throes of modernisation. The process was slow, constrained by finance, dependent on British supply, and uneven in its results, but it was real. Since the mid-1930s, the Army had been placing orders for modern equipment, updating mobilisation planning, experimenting with mechanisation, and attempting to keep pace with contemporary British doctrine.
This is an important qualification to the common claim that New Zealand entered the Second World War wholly unprepared and equipped no better than it had been in 1918. The reality was more complex. Material deficiencies remained serious, but the Army was not intellectually or administratively stagnant. From 1934, the Director of Ordnance Services, Major Thomas Joseph King, worked to ensure that key ordnance positions were held by competent and experienced personnel. At the same time, New Zealand staff followed British doctrinal developments as closely as practicable, including changes in Field Service Regulations, mechanisation, training, mobilisation planning, and the implications of modern weapons.[14]
The same was true in the Army Service Corps. Although New Zealand’s transition from horse transport to motor transport was slow, it was already underway by the time Mackesy arrived. As late as the mid-1930s, each military district still retained one horse transport section and only one motor transport section, yet the direction of travel was clear. Major-General J. E. Duigan reported in 1937 that successful wartime transportation depended upon the efficient employment of civil resources and that the Army was now dependent on the motor industry for its mobility. Trials conducted in 1936 and 1937 had shown that motor transport could replace horse-drawn unit transport, and Duigan stated that this would be universally adopted in future. By 1938, despite the limited number of trucks and lorries held by the New Zealand Military Forces, Territorial Army Service Corps units were already conducting increasingly motorised convoy training.[15]
The archival record supports this more nuanced interpretation across both equipment and logistics. A 1938–39 Ordnance file shows a range of modern stores and equipment either on order, received, or being managed through requisition. These included Bren guns and components, Bren gun maintenance spares, 3-inch mortars, 2-pounder anti-tank guns and equipment, wireless sets No. 9 and No. 11, anti-gas equipment, Boys anti-tank rifles, portable cookers, tentage, medical equipment, signalling equipment, and large quantities of ammunition.[16]
The follow-up material to Mackesy’s report makes the same point. In relation to specialised vehicles, it noted that equipment requirements had to be considered as a whole and obtained from the most suitable source. It also recorded that the Army Department’s existing programme already provided for 39 Bren carriers, with six received and a further twelve on order, and eighteen six-wheeled field artillery tractors, with twelve previously ordered tractors already received.
Mackesy’s significance, therefore, was not that he invented the requirement for modernisation. Rather, he validated and sharpened it. He exposed the scale of the gap between partial modernisation and a force capable of mobilisation to the war establishment. The Army had begun to move beyond its First World War equipment base, and its staff were attempting to keep abreast of modern doctrine and equipment trends. Still, the process remained incomplete, under-resourced, and insufficient for the demands that war would impose.
A fair reading is that Mackesy reinforced an existing direction of travel and gave it strategic urgency. He turned modernisation from a series of equipment orders, doctrinal updates, and mobilisation preparations into a whole-force capability problem. The issue was no longer simply whether New Zealand had begun ordering modern equipment. It was a question of whether that equipment, together with trained personnel, ammunition reserves, storage, transport, maintenance, mobilisation depth, and supporting infrastructure, could be integrated into a force ready for war.
The iceberg effect
The modern ILS Handbook uses the “iceberg effect” to explain why ILS is necessary. It notes that capability planning and procurement have traditionally focused on equipment acquisition, while failing to account for Whole of Life Cost and Through Life Management. The visible acquisition cost is on the surface, while beneath it lie the larger, often less visible costs and requirements associated with operations, distribution, maintenance, training, technical data, supply support, test and support equipment, software, and disposal. The Handbook states that all these elements should now be considered early and planned across the life cycle, from policy and strategy to disposal.[17]
The ILS “iceberg effect”, showing how acquisition cost is only the visible portion of capability cost. Mackesy’s 1939 report anticipated this logic by linking modern weapons and vehicles to ammunition reserves, storage, magazines, garages, training, personnel, and procurement lead times.
Mackesy’s report and the follow-up work on Recommendations 42 and 43 show that the Army was already grappling with a similar problem in 1939. Modern weapons could not be considered in isolation. They required ammunition reserves, practice stocks, storage, magazines, garages, trained personnel, replacement depth, and a procurement plan that recognised lead times and sources of supply.
In other words, Mackesy saw beneath the surface of acquisition. He understood that the mere purchase of modern equipment would not solve the Army’s problem unless the less visible support system was also resourced.
The danger of paper capability
One of Mackesy’s most powerful themes was the difference between paper strength and usable strength. His examination of the Auckland defences showed this clearly. The 13th Heavy Battery required 338 all ranks for war manning of the fixed defences, but at the time of his visit, it had only a fraction of that number available. The Fortress Battalion had a war establishment of 773 all ranks, but a strength of only 320, of whom about sixty were considered physically unfit for war service.[18]
This was more than a manpower complaint. Mackesy was testing the force against its assigned task. A unit might exist on paper, but if it could not be manned, trained, equipped, and mobilised when required, it was not a real capability. This is directly comparable with modern capability assurance. Modern ILS and capability management similarly ask whether a capability is available, supportable, deployable, and sustainable, not merely whether it exists on an equipment register or establishment table.
Mackesy’s criticism was especially relevant because the Army’s mobilisation model relied heavily on the Territorial Force expanding rapidly in an emergency. He saw that this expansion would not be simple. Men might have little or no training. Units would need to be built up from inadequate peacetime strengths. Composite units would disintegrate on mobilisation into their component regiments. The gap between peacetime organisation and wartime effectiveness was therefore not administrative. It was operational.
Normalisation of deviance and the acceptance of military risk
A further way to read Mackesy’s report is as an early warning against what would now be called the normalisation of deviance.[19] The New Zealand Army had not suddenly become under-prepared in 1939. Rather, the condition Mackesy described had developed over time. Reduced establishments, obsolete equipment, inadequate reserves, limited training opportunities, insufficient accommodation, and reliance on rapid improvisation had gradually become accepted as normal peacetime conditions.
This was not necessarily the result of neglect by any one individual. Mackesy himself was careful not to criticise individuals or bodies of individuals, and he acknowledged that earlier decisions may have appeared necessary at the time. The problem was more systemic. Successive economies, assumptions, and deferrals had created a situation in which the Army’s deficiencies were visible but had not yet forced decisive correction.[20]
The extent to which these deficiencies had already become visible was demonstrated by the so-called “Four Colonels’ Revolt” of May 1938. Colonels Neil Lloyd Macky, C. R. Spragg, A. S. Wilder, and F. R. Gambrill publicly challenged official assurances about the state of the Territorial Force, arguing that New Zealand’s citizen army had been reduced below what was required for national defence, that recruiting and training were inadequate, and that morale had suffered. Their action breached military regulations and led to their posting to the retired list, but it also exposed the depth of professional unease within the senior Territorial leadership. Mackesy’s report should therefore be read against this background. He was not the first to identify the Army’s weaknesses.[21] Still, his external assessment gave formal shape to concerns that experienced New Zealand officers had already risked their careers to express.
In modern ILS terms, Mackesy was forcing decision-makers to confirm the impact of inaction. The ILS Handbook states that ILS principles include recognising constraints, focusing ILS effort where it will deliver the greatest benefit, and confirming the impact of any inaction.[22] Mackesy’s report did precisely that. He showed that what had become administratively familiar in peace would become dangerous on mobilisation.
The Army could still parade, train, administer, and maintain the outward form of a military system, but the underlying support structure was fragile. It lacked sufficient trained personnel, modern equipment, ammunition reserves, replacement weapons, accommodation, and mobilisation depth. Because those weaknesses had existed for some time without immediate disaster, they risked being accepted as the norm.
The declaration of war changed the calculation. What had been tolerable as a peacetime economy became a mobilisation risk. Mackesy’s report, therefore, demonstrates the danger of treating chronic under-resourcing as an acceptable condition. The absence of an immediate crisis had made shortages familiar, and that familiarity had made them appear manageable. Yet war removes the margin that peacetime under-resourcing depends upon.
Mackesy’s anti-improvisation principle
Mackesy’s report contains one of the clearest statements of the principle that underpins modern ILS. He warned that unless matters had been studied in peace, confusion and unnecessary loss of life and treasure would result when war forced unexpected action. He accepted that improvisation in war was possible but added that improvisation without previous thought and training was a costly expedient.[23]
This is, in essence, the logic of ILS. It exists to prevent an organisation from discovering too late that the ammunition reserve is inadequate, the spares are unavailable, the technical documentation is missing, the training pipeline is incomplete, the facilities are unsuitable, the supply chain lead time is too long, or the force cannot be sustained under operational conditions.
Mackesy’s language was that of 1939. The principle was timeless. A capability must be prepared before it is required. It cannot be wished into existence on mobilisation.
Recommendations 42 and 43, from report to action
The strongest evidence of ILS-like thinking appears in the follow-up work on Mackesy’s Recommendations 42 and 43, concerning the supply of modern equipment for the Army and the provision of ammunition reserves. The memorandum submitted by Major-General J. E. Duigan, Chief of the General Staff, in August 1939 divided the matter into three connected parts.
Part A dealt with the provision of reserve ammunition for weapons already in possession or already ordered. Part B dealt with the provision of modern fighting and technical equipment for the Territorial Force, together with the necessary ammunition reserves for new weapons. Part C addressed the magazine, garage, and storage accommodation required to house the equipment and ammunition covered by Parts A and B.
This structure is crucial. The Army was not simply proposing to buy modern weapons. It was linking weapons to ammunition, reserves, accommodation, garages, magazines, and storage. It also recommended that the projects be considered as a whole and that, if approved in principle, provision be made over a period of years, in line with the time required to obtain the various types of equipment and ammunition. Immediate local expenditure on accommodation was recommended, while enquiries were to be made into the most satisfactory sources of supply, taking account of both cost and delivery date.
This is ILS in all but name. Modern ILS would frame the same issue in terms of supportability, facilities, supply support, support equipment, training consumption, war reserves, procurement phasing, and whole-of-life cost. The 1939 language was different, but the logic was closely aligned.
The same logic is evident in the wartime expansion of the NZAOC. In 1937, the Ordnance establishment was still being framed around peacetime assumptions, limited mechanisation, and a relatively small depot and workshop structure. The Director of Ordnance Services had warned that if any great development of mechanisation occurred during the next five years, the Ordnance Workshop establishment would probably prove inadequate.
By 1942, that warning had become reality. The scale of mobilisation, equipment receipt, ammunition storage, inspection, accounting, repair, and issue had made the pre-war structure insufficient. War Cabinet approved an amended Ordnance Depot establishment of 30 officers and 1,019 other ranks, distributed across Trentham, Northern District, Central District, and Southern District. In parallel, it authorised a revised Ordnance Workshops establishment of 425 all ranks, comprising 15 officers and 410 other ranks, covering the workshops at Trentham, Devonport, and Burnham. Both the Ordnance Depot and Ordnance Workshops establishments were to be treated as Dominion establishments, rather than as separate fixed establishments for each depot or workshop.[24]
The scale of that support system is clearer when the pre-war and wartime establishments are placed side by side.

Pre-war establishment position, 1937–38
1942 wartime establishment
What changed

Small mixed military and civil establishment, framed around peacetime assumptions and the existing Territorial Force
30 officers and 1,019 other ranks, a total of 1,049, across Trentham, Northern District, Central District, and Southern District
Depot support became a national supply, storage, accounting, receipt, issue, and distribution system
Ordnance Workshops
The limited workshop structure was considered vulnerable if mechanisation expanded. The 1938 Armament Section proposal included 3 officers, 9 WO1 artificers, and 25 other ranks across Trentham, Devonport, and Burnham
15 officers and 410 other ranks, a total of 425, covering Trentham, Devonport, and Burnham
Technical repair, inspection, modification, and maintenance became a national sustainment function
Establishment principle
Localised peacetime structure
Both depot and workshop establishments are treated as Dominion establishments.
This was significant. It meant that NZAOC manpower was being managed as a national support capability, adaptable and transferable in response to the changing pressures of mobilisation, storage, repair, inspection, and distribution. The depots represented the system’s supply, accounting, storage, receipt, issue, and distribution functions. The workshops represented the technical sustainment arm, including armament artificers, instrument artificers, wireless artificers, carpenters and joiners, painters, plumbers and tinsmiths, blacksmiths and welders, electricians, clerks, storemen, and labourers.
Taken together, these two NZAOC establishments show that modernisation did not stop at acquisition. Modern equipment had to be received, inspected, accounted for, stored, issued, repaired, modified, maintained, and technically supported. In modern ILS terms, the Mission System had forced the expansion of the Support System beneath it.
Equipment, ammunition, reserves, and war wastage
The follow-up paper on Recommendations 42 and 43 showed that the Army was already thinking in terms of holdings, orders, war reserves, and annual practice expenditure. In Part A, the schedules showed ammunition held in the Dominion or on order, what was considered necessary as a war reserve, and what expenditure was required for annual practice.[25]
Part B extended this logic to modern weapons and technical equipment. It identified the nature and number of modern weapons and equipment required to replace or supplement obsolete or obsolescent equipment, to complete the Territorial Force war establishment, and to provide a 25 per cent reserve. It also calculated the ammunition required for those new weapons on a similar scale. [26]
This was not a narrow procurement. It was capability planning. It connected equipment to force structure, reserves, ammunition, training, and replacement needs. The inclusion of a 25 per cent reserve reflected an understanding that war consumes equipment as well as ammunition. Weapons break, vehicles wear out, losses occur, and reinforcements require training and equipping. The Army was therefore not planning merely for possession, but for endurance.
The scale of the problem is clearer when the weapon and ammunition returns are viewed across the period from 1939 to 1944. In August 1939, New Zealand’s modernisation remained uneven. Older weapons such as the 18-pounder, 4.5-inch howitzer, 60-pounder, and 6-inch howitzer still formed part of the artillery inventory, while modern weapons such as the 25-pounder, 2-pounder anti-tank gun, Bren gun, Bofors 40-mm anti-aircraft gun, and 3.7-inch anti-aircraft gun were either on order or still being discussed. By March 1944, the position had changed dramatically. Quartermaster General returns show 255 25-pounders, 219 2-pounder anti-tank guns, 226 6-pounder anti-tank guns, 10,991 Bren guns, and very large ammunition holdings, including 920,701 rounds for the 25-pounder, 423,259 rounds for the 2-pounder anti-tank gun, 428,023 rounds for the 3.7-inch anti-aircraft gun, and 608,984 rounds for the Bofors 40-mm. These figures show that Mackesy’s concern was not theoretical. Modernisation required not only weapons, but reserves, ammunition, storage, distribution, trained personnel, and a system capable of sustaining war consumption.

The problem of obsolete equipment
The need for this enlarged Ordnance support system was reinforced by the condition of the equipment itself. The follow-up material to Mackesy’s report made clear that the Territorial Force remained heavily dependent on old equipment. Apart from coastal defences and a few items of modern equipment already obtained or on order for the Field Force, much of the Territorial Force’s equipment remained of the pattern used in the previous war. Existing small arms were insufficient to equip the Territorial Force at war strength, and, except for rifles, there were no reserve weapons to replace war wastage or train reinforcements. [27]
This was a strikingly modern supportability problem. A force may possess equipment, but if that equipment is obsolete, insufficient, unsupported, or lacks reserves, the capability remains fragile. Mackesy and the Army Board understood that modernisation had to address both first-line equipment and depth. It was not enough to equip the first increment of a force. The system had to be capable of replacing losses, training reinforcements, and sustaining the force over time.
Lead time, source of supply, and industrial reality
The follow-up paper also recognised the hard limits imposed by procurement lead times and industrial capacity. It noted that new equipment could not be obtained from Great Britain until more than twelve months after the outbreak of war, and that even if ordered immediately under peace conditions, delivery would take place only over several years, depending on manufacturing time and the priority given to New Zealand’s orders. It also observed that ordering requirements in instalments were uneconomical and would not necessarily produce earlier or more uniform delivery.[28]
This is another point of strong alignment with modern ILS and capability management. Today, this would be described as supply chain risk, industrial capacity, source-of-supply analysis, procurement phasing, delivery risk assessment, and schedule dependency. In 1939, it was practical military administration. New Zealand could not assume that equipment would be available when war came. It had to consider where equipment could be sourced, how long it would take to arrive, what priority New Zealand would receive, and whether local expenditure could begin immediately on the supporting infrastructure.
Facilities as part of the capability
Part C of the follow-up paper addressed magazine, garage, and storage accommodation. It estimated the additional accommodation needed for ammunition already on order, ammunition under Part A, ammunition under Part B, vehicle garage accommodation, and general storage.
This is one of the clearest examples of the programme’s support logic. Modernisation was not treated as complete once weapons or vehicles had been ordered. The Army needed somewhere to store ammunition safely, somewhere to garage vehicles, and somewhere to hold equipment. The capability, therefore, depended on the estate as much as on the equipment itself.
This point is reinforced by the 1940 summary of estimated Army expenditure. Although prepared before Japan entered the war, the report is significant because it was already looking beyond immediate equipment purchases to the infrastructure required for mobilisation, home defence, training, storage, maintenance, and sustainment. In that sense, it anticipated many of the pressures that would later become urgent after the Pacific War began. Alongside weapons, ammunition, vehicles, and general equipment, the summary included provision for buildings, water supply, roads, hospital accommodation, officers’ quarters, ordnance stores, garages, and workshops.[29]
The range of facilities identified in the 1940 expenditure summary shows that infrastructure was being treated as a mobilisation requirement.

Evidence from the 1940 expenditure summary
Capability significance
Buildings and camp infrastructure
Buildings, water supply, roads, hospital accommodation, officers’ quarters, and other camp works were included
Shows that mobilisation required a physical estate able to house, train, administer, and sustain an expanded force
Ordnance stores
Provision was included for Ordnance stores
Equipment and ammunition required controlled storage, accounting, preservation, and issue facilities
Weapons, vehicles, instruments, and technical stores required repair, modification, maintenance, and inspection facilities
Magazine and ammunition accommodation
The wider Mackesy follow-up programme identified magazine, garage, and storage accommodation as part of the equipment and ammunition problem
Ammunition reserves were only useful if they could be safely stored, managed, protected, and issued
Roads and water supply
Roads and water supply were included as expenditure items
Camps, depots, magazines, and workshops required basic infrastructure before they could function as military facilities
The table illustrates that facilities were not an administrative afterthought. They were part of the support system that allowed weapons, ammunition, vehicles, stores, and personnel to become usable military capability. The timing sharpens the significance. In 1940, New Zealand was not yet at war with Japan, but the Army was already identifying the estate and infrastructure requirements that would underpin mobilisation and home defence. When the Pacific War later made the threat to New Zealand more immediate, many of these requirements were no longer theoretical.
Training and the human system
Mackesy also understood that trained people were central to capability. His report criticised the absence of regular units, the scattering of regular personnel across instructional and administrative duties, and the lack of a trained force available for mobilisation to protect while the Territorial Force prepared itself. He also noted that officers lacked opportunities to exercise tactical command in peace.[30]
Again, this reflects a whole-system view. Equipment required trained operators, trained commanders, trained instructors, and training areas. The Army’s problem was not merely material. It was institutional. Modern weapons, vehicles, ammunition, stores, workshops, garages, and magazines could not generate capability unless trained personnel existed to use, account for, maintain, repair, distribute, and command them.
The wartime expansion of the NZAOC reinforces this point. By 1942, the Ordnance Depot and Ordnance Workshops establishments had both become Dominion establishments, reflecting the need to manage trained manpower nationally rather than as a series of isolated local appointments. The depots required personnel able to handle receipt, accounting, storage, issue, and distribution, while the workshops required armament artificers, instrument artificers, wireless artificers, tradesmen, clerks, storemen, and labourers able to support increasingly technical equipment. The growth of the NZAOC was therefore not simply an increase in numbers. It was the creation of a trained human support system beneath modernisation.
The modern ILS Handbook identifies training support as one of the 10 ILS elements, involving the resources, skills, and competencies necessary to acquire, operate, support, and dispose of a capability system. It also identifies personnel as a separate ILS element, covering human resources and the prerequisite training, skills, and competencies required to acquire, install, test, train, operate, and support the capability system throughout its life cycle. Mackesy’s concern with Regular Forces, Territorial training, instructors, officers, cadets, and reserves fits closely with that logic.
Mapping Mackesy against the modern 10 ILS elements
The NZDF ILS Handbook lists 10 ILS elements: engineering support, maintenance support, supply support, packaging, handling, storage and transportation, training support, facilities, support and test equipment, personnel, technical data, and computer support.[31] Mackesy’s report and the follow-up work do not align with all these equally, but the comparison is revealing.

The Mackesy-era equivalent visible in the reports
Alignment
Engineering support
Modern equipment selection, mechanisation, suitability of weapons and vehicles
Partial
Maintenance support
Garages, stores, vehicle support implications, mechanisation
Partial
Supply support
Ammunition reserves, war reserve stocks, replacement weapons, source of supply
This mapping helps keep the argument balanced. Mackesy was not applying modern ILS in full. There is little visible evidence of what would now be called technical data management, configuration management, Reliability, Availability, and Maintainability analysis, Level of Repair Analysis, Failure Modes, Effects, and Criticality Analysis, or computer support. But the strongest areas of alignment, supply support, training support, facilities, personnel, storage, transportation, and supportability planning, are precisely the areas most central to whether a mobilisation force could be made real in 1939.
Whole-of-life awareness, not modern Whole of Life Costing
The ILS Handbook states that Whole of Life Cost incorporates all costs attributable to a capability throughout its life cycle, and that many of these costs are incurred during the In-Service phase, even though key cost decisions are made much earlier.[32] Mackesy’s work should not be described as Whole of Life Costing in that modern technical sense. It did not model all costs across acquisition, operation, support, upgrade, and disposal.
However, it did move well beyond simple purchase cost. The follow-up work considered capital costs, ammunition reserves, annual practice expenditure, magazines, garages, storage accommodation, delivery times, sources of supply, and phased expenditure over several years.[33] That was not modern Whole-of-Life Costing, but it was a clear form of whole-of-support awareness.
This distinction matters. It avoids anachronism while preserving the core argument. Mackesy was not using a modern costing model, but he was applying the broader principle that capability costs do not end with equipment acquisition.
Was Mackesy’s report parked?
It would be fair to say that Mackesy’s report was initially parked, but that phrase needs careful handling. It was not simply ignored. Mackesy himself stated that his suggestions would require careful investigation before action could be taken. That gave the Government and the Army Department room to treat the report as a major advisory document rather than to implement it in full immediately.
In May 1939, New Zealand was still technically at peace. Mackesy’s broader recommendations, covering the Regular Force, Territorial Force, training, pay, prestige, reserves, cadets, accommodation, mobilisation, equipment, ammunition, ordnance services, and financial administration, represented a substantial reform agenda. It was unlikely that such a programme would be adopted in its entirety within weeks.
Once war was imminent, however, the position changed. The report appears to have been used selectively, with attention narrowing to those parts that could be translated most directly into urgent military preparedness. Recommendations 42 and 43, dealing with modern equipment and ammunition reserves, received particular attention. A memorandum of 22 September 1939 confirms this shift, noting that the original estimates had been prepared on a peacetime basis and that urgent orders had since been placed for 18-pounder gun ammunition, 4.5-inch howitzer ammunition, and 100 Marmon-Herrington adapters fitted to vehicles.[34]
Mackesy’s report, therefore, became less a comprehensive reform blueprint and more a menu of urgent war-preparedness measures. The deeper structural issues, such as the creation of regular units, institutional training reform, and the broader status of the Army, did not receive the same immediate attention. What moved first were the recommendations most directly connected to mobilisation, equipment, ammunition, mechanisation, storage, and mobility.
ILS as formalised old-fashioned military planning
The comparison with modern ILS should not be overstated. Mackesy was not applying a formal ILS framework. His report does not show modern logistics support analysis records, reliability and maintainability modelling, configuration management databases, digital technical data, performance-based support contracts, or through-life governance structures.
The ILS Handbook describes modern ILS as structured, iterative, life cycle-based, and linked to Through Life Support, Systems Engineering, Logistics Support Analysis, Whole of Life Costing, supportability testing, configuration management, RAM, and other technical disciplines. Mackesy’s 1939 work was not that.
Yet the underlying method is unmistakably aligned. Mackesy and the subsequent Army Board work treated capability as an integrated system. They considered personnel, training, equipment, ammunition, reserves, accommodation, storage, mobilisation, source of supply, lead time, cost, and delivery. The later expansion of the NZAOC Depot and Workshops establishments as Dominion establishments, together with the 1940 expenditure planning for buildings, roads, water supply, ordnance stores, garages, and workshops, shows that this logic moved beyond paper analysis into practical mobilisation planning. The Army understood that a force could not be judged by its nominal existence, or by equipment on order, but by its ability to mobilise, train, store, issue, repair, move, reinforce, and sustain itself under wartime conditions.
This is the essential point. Modern ILS did not invent the idea that a military capability must be supportable. It formalised an older military truth.
Contemporary reflections for logisticians
Mackesy’s report should not be read as a simple checklist against which to judge contemporary logistics practice. The strategic setting, technology, force structure, governance, and scale of modern defence capability are vastly different from those of 1939. Nor should the report be used to imply that modern logisticians are repeating the failures of an earlier generation. Its value lies elsewhere. It provides a historical case study in how supportability, preparedness, and sustainment can determine whether military capability is real or merely assumed.
For contemporary logisticians, the first reflection is that capability must be understood as a system. Mackesy’s report did not treat weapons, vehicles, ammunition, personnel, training, storage, accommodation, and mobilisation as separate subjects. He examined them as interdependent parts of one military problem. The subsequent wartime expansion of NZAOC depots and workshops, and the inclusion of facilities such as stores, garages, workshops, roads, water supply, and accommodation in 1940 planning, reinforce the same point. A capability may be acquired through equipment, but it is delivered through the support system that allows it to be stored, issued, maintained, repaired, moved, supplied, trained, and sustained.
The second reflection is that gaps are easiest to tolerate when they have become familiar. Mackesy did not describe an Army that had suddenly become deficient. He described a force that had adapted over time to shortages, workarounds, obsolescence, limited reserves, inadequate establishments, and constrained training. In modern terms, this highlights the importance of identifying the impact of inaction. A shortage that has been managed for years may still be a real operational risk when circumstances change.
The third reflection is that mobilisation and sustainment cannot be improvised at the point of crisis. Mackesy’s warning about improvisation without previous thought and training remains relevant, not because the conditions of 1939 are directly comparable to today, but because the principle is enduring. Supply chains, storage, maintenance arrangements, trained personnel, technical data, contracts, transport, infrastructure, workshops, and reserves all require time, investment, facilities, and deliberate planning before they are needed.
The fourth reflection is that modernisation is not complete when equipment is ordered. New Zealand was already modernising before Mackesy arrived, with modern equipment received, further items on order, and staff attempting to remain current with British doctrine. Yet Mackesy’s report showed that partial modernisation was not enough. Equipment had to be connected to ammunition reserves, trained users, storage, transport, maintenance, repair, mobilisation depth, and supporting infrastructure. The 1942 Ordnance establishments and the 1940 facilities planning show the practical consequence of that principle: modernisation created a support burden that had to be manned, housed, equipped, and sustained.
Finally, Mackesy’s report demonstrates the value of honest external examination. His assessment was not perfect, nor was it a full implementation plan, but it forced attention onto the relationship between stated capability and actual readiness. For logisticians, that is perhaps the most useful enduring point. The purpose of logistics advice is not simply to support decisions already made, but to clarify what those decisions require if the capability is to be safe, available, supportable, repairable, and sustainable.
Read this way, Mackesy’s report is not a judgment on the present. It is a reminder that logistics has always been central to the credibility of military capability. The language has changed, and modern ILS has formalised the process, but the professional obligation remains familiar: to ensure that capability can be generated, supported, and sustained when required.
Conclusion
Major-General Mackesy’s 1939 report should be read not simply as a criticism of the New Zealand Army, but as a whole-force capability assessment. He arrived when the Army was already modernising, but that modernisation remained incomplete. His value lay in exposing the gap between equipment acquisition and usable military capability.
The follow-up work on Recommendations 42 and 43, together with the later expansion of Ordnance Depot and Ordnance Workshops establishments, demonstrates that this was not an abstract concern. Modern weapons, vehicles, ammunition, and technical stores required reserves, storage, magazines, garages, workshops, trained personnel, accounting systems, repair capacity, and distribution arrangements. The 1940 facilities planning reinforces the same point. Before the Pacific War made the threat to New Zealand more immediate, the Army was already identifying the estate and infrastructure needed to support mobilisation and home defence.
Measured against the modern NZDF ILS Handbook, Mackesy’s work was not ILS in the contemporary technical sense. It lacked the formal structures, terminology, analytical tools, and governance of modern capability management. Yet it clearly reflected the principles that ILS now formalises; early attention to supportability, recognition of whole-of-support requirements, integration of Mission System and Support System considerations, and the need to design capability that can actually be prepared, used, maintained, repaired, and sustained.
For contemporary logisticians, Mackesy’s report is best read as a historical reflection rather than a judgement. It reminds us that logistics is not a secondary activity performed after capability decisions have been made. It is part of the capability itself. Equipment without trained people, ammunition, spares, storage, transport, maintenance, infrastructure, workshops, repair capacity, and mobilisation depth is not a complete military capability.
The terminology has changed, the governance has become more formal, and the tools have become more sophisticated, but the underlying principle remains the same:
A capability is not real until it can be trained, equipped, supplied, stored, moved, maintained, repaired, reinforced, and sustained when required.

Such kits typically involved the fitting of a driven front axle, transfer case, driveline modifications, and associated mounting components. Their inclusion alongside urgent ammunition orders shows that, by September 1939, New Zealand’s preparations were extending beyond stockpiling munitions to improving the field mobility of its vehicle fleet; “Trucks converted with Marmon-Herrington All-Wheel Drive Conversion Kits,” Marmon-Herrington military vehicles, 2002, 2026, https://www.mapleleafup.nl/marmonherrington/truck.html
NZAOD and New Zealand Army Bulk Refuelling in Malaysia, 1985–1989
The photographs accompanying this article show New Zealand Army Unit Bulk Refuelling Equipment (UBRE) in practical field use during exercises in Malaysia in the second half of the 1980s. The vehicles were operated by the New Zealand Advanced Ordnance Depot (NZAOD) in Singapore, supporting New Zealand forces training in the region during the final years of New Zealand Force Southeast Asia.
Evidence now places NZAOD’s truck-mounted bulk fuel support in Malaysia from at least Exercise Pemburu Rusa in 1985 through to Exercise Taiha Tombak XI in 1989, the final exercise for NZAOD. These images provide a rare visual record of how New Zealand’s tactical bulk refuelling capability appeared in service, not as a polished catalogue item or purpose-designed military refuelling module, but as a pragmatic, improvised system assembled from available tanks, pumps, hoses, fittings, and vehicle platforms.
The images are important because they show the reality behind later Army correspondence, which described the in-service New Zealand UBRE as an “ad hoc combination” of equipment. That description was not an exaggeration. By the late 1980s, the New Zealand UBRE was a field-engineered arrangement based around a 2000-litre rigid tank, a pallet-mounted dispensing pack, and an RL Bedford truck. The system worked, but it was never an ideal or fully purpose-designed solution. It was a practical answer to a practical problem, moving and issuing fuel forward in conditions where jerrycans alone were too slow, labour-intensive, and inefficient.
The ad hoc New Zealand UBRE
In its typical late-1980s form, the New Zealand UBRE consisted of a 2000-litre rigid fuel tank shackled or otherwise secured to the deck of an RL truck in NZAOD and a UNIMOG truck for NZ-based units. Nearby, a palletised dispensing pack was mounted, containing a pump, filter, meter, hoses, and fittings. Some pumps were self-contained, consisting of a pump, filter, and meter within a robust frame. Other pumps were made up of separate pump, filter, and meter components that were often grouped together on a pallet base and secured with steel banding tape.
The tank and dispensing pack were connected by two-inch hoses using camlock fittings. These fittings could be wired shut, but they required constant checking during movement, as vibration and road travel could work them loose. Fuel was dispensed to vehicles through a one-inch hose. In some cases, this could be fitted to a hose reel, but more often the hose was simply wound around the dispensing pack for stowage.
In New Zealand, a UBRE could be configured to dispense petrol, diesel, or Aviation Turbine Fuel. However, in Singapore, the NZAOD UBREs were configured specifically for petrol, then commonly referred to as MT Gas. Each issue was recorded on an MD638 Issue Sheet in litres, based on the meter reading. This detail is important. Although the equipment itself was improvised, the accounting and control of fuel remained formalised. The operator had to issue fuel, read the meter, record the quantity, and maintain a written record of consumption. In that sense, the UBRE was not merely a pump and tank on the back of a truck; it was part of a wider supply and accountability system.
The photographs show the dispensing pack either sitting exposed on the truck deck, with hoses visible around the tank and pump assembly or with the vehicle sideboards remaining fitted. The arrangement was functional, but it relied heavily on operator vigilance, routine checks, and practical experience.
Taiha Tombak X
Several photographs show the UBREs in convoy or road movement. These views make clear how exposed the equipment was. The dispensing pack, hose work, and tank fittings sat on the open deck, secured for movement but still vulnerable to vibration, weather, and rough roads. This was the kind of operating environment that made loose couplings, leaking fittings, and constant equipment checks an everyday concern.
Pemburu Rusa88
Other images give a clearer side view of the RL-mounted UBRE. The large rectangular tank dominates the deck, with the dispensing pack positioned at the rear. The visible placarding, external hose work, and “No Smoking within 13M” markings highlight its role as a fuel-carrying and fuel-dispensing vehicle rather than a general cargo truck. The images also illustrate one of the central compromises of the system. The RL provided mobility and load-carrying capacity, but the refuelling equipment was not integrated into the vehicle as it would be in a purpose-built tanker or modern fuel module. It was mounted onto the truck, rather than designed as part of it.
Taiha Tombak IX
One of the most useful photographs shows three UBRE-equipped vehicles together in Malaysia. Rather than isolated refuellers, the image captures a small mobile fuel element, with each RL carrying a 2000-litre rigid tank and associated dispensing equipment. This gives a better sense of how the ad hoc UBRE capability could be grouped to support exercises, providing a dispersed yet practical bulk refuelling capacity. It also highlights the variation within the system. Although each vehicle performed the same broad role, the equipment was not a fully standardised, purpose-designed refuelling module. It was a collection of workable configurations assembled from available tanks, pumps, hoses, fittings, and vehicle platforms. That flexibility was useful in the field, but it also created challenges for maintenance, training, and safety.
Lunch stop Taiha Tombak XI
A mobile field fuel point
The wider photographic set adds further detail to how these improvised UBREs were actually operated. They were not simply trucks carrying fuel tanks. In the field, they could be established as temporary fuel issue points, with warning signs, no-smoking controls, drums used to mark or control the area, and fuel dispensed by hose directly into vehicles or into containers.
Pemburu Rusa88
One image shows a controlled fuel point layout, with drums and signage forming a visible boundary around the dispensing area. Others show UBREs in harbour, in hides, on roads, and at exercise locations, demonstrating that the system was used as a mobile field fuel capability rather than as static depot equipment.
UBRE Hide Taiha Tombak XI
The photographs also show fuel being issued directly to vehicles and, in some cases, into jerrycans or other containers.
Taiha Tombak XI
This confirms that the UBREs were not limited to bulk vehicle refuelling alone. They could support vehicle replenishment, container filling, and local redistribution of MT Gas as required. The equipment was flexible, but that flexibility came from operator skill and improvisation rather than from a formally integrated design.
Kerbsiode convoy refuelling Taiha Tombak X
One photograph of field administration is particularly useful. It shows the paperwork side of the operation, reinforcing that the fuel issue remained formally controlled even when the equipment was improvised. Issues were measured with the meter and recorded in litres on the MD638 Issue and Receipt Sheet. At the end of each day, the MD638 issue and receipt sheets would be reconciled, and the balance would be entered on an AFNZ 28 Supplies and POL Ledger Card. This was then checked against the physical stock by dipping the tank. The result was a daily record of receipts, issues, book balance, and actual balance, with allowance made for normal tolerances, spillage, and calculated measurement variation. The UBRE may have been ad hoc in construction, but the discipline surrounding fuel accounting remained intact.
The activities shown in these photographs should be read as a snapshot rather than a complete record of NZAOD Petroleum Operator activity in Southeast Asia. They capture the principal known examples where UBREs were utilised in Malaysia between 1985 and 1989, but Petroleum Operators also supported New Zealand Transport Squadron activity and other exercises or depot requirements. They also supported helicopter refuelling for 141 Flight RNZAF. The UBREs were therefore only one visible part of a wider petroleum support function that linked vehicle movement, air support, depot supply, and field sustainment during New Zealand’s final years in Singapore and Malaysia.
Reconciling 638s Taiha Tombak X
The introduction of the UBRE idea
During this period, the term UBRE itself was not widely understood outside the Petroleum Operator community. It appears to have entered New Zealand Army usage through officers and soldiers who had been exposed to British petroleum doctrine and equipment, including Phil Green and H. J. Carson. Carson and Green were officers who had seen British UBRE mounted on Bedford or similar standard trucks during their time on the long petroleum course in the United Kingdom. They brought the concept back into New Zealand service, where it was discussed, adapted, and reinforced through Petroleum Operator courses.
British Army UBRE
British Army UBRE
In this sense, UBRE was not just a piece of equipment. It was a British idea filtered through New Zealand circumstances and given practical form by petroleum operators who understood that the Army needed something better than jerrycans alone, even if a fully engineered solution was not yet available.
Earlier New Zealand Petroleum Operators in Southeast Asia included Billy Vince, Stu McIntosh, Ian “Butch” Hay, Alan Barnes, Brian Calvey, John Weeds, and A. J. Weston. This list is not exclusive, and any omissions are regretted. Their service provides important continuity to the later NZAOD UBRE story. The ad hoc RL-mounted UBREs of the late 1980s did not appear in isolation. They developed from an established petroleum support presence in Southeast Asia, shaped by earlier operators, older equipment, field expedients, and the practical demands of supporting New Zealand forces in Malaysia and Singapore.
Earlier evidence, Exercise Pemburu Rusa, 1985
The use of NZAOD bulk fuel equipment in Malaysia can now be pushed back before the 1987–1989 photographic record. A contemporary recollection titled “Driving in Malaysia, An Experience” records that, after arriving in Singapore in late August 1985, Staff Sergeant Stu McKintosh recalls his first introduction to driving on the Malay Peninsula came during Exercise Pemburu Rusa, conducted between 2 and 31 October 1985. After initially driving the escort Land Rover for an RT-25 rough-terrain forklift, he soon found himself driving an RL fitted with a single 2000-litre tank on about four refuelling runs back to Singapore.[1]
Each trip took around two hours one way, despite the distance being only about sixty miles, with road conditions, traffic, and local driving habits contributing to the slow journey. This account is important because it confirms that NZAOD was operating truck-mounted bulk fuel arrangements in Malaysia before the later Taiha Tombak photographs. It does not prove that the exact UBRE configuration seen in the later images was already in routine use, but it does show that RL-mounted fuel carriage and refuelling support formed part of NZAOD’s exercise support system by late 1985.
It also reinforces a recurring theme in the photographic evidence, fuel support in Malaysia was never simply a technical matter. It required drivers and petroleum operators to move heavy, fuel-carrying vehicles over long distances and through demanding traffic conditions while maintaining the safety and accountability expected of military fuel operations.
The 1985 Pemburu Rusa experience helps explain the later Taiha Tombak arrangements. By the time larger exercises were being supported in the late 1980s, NZAOD already had practical experience moving fuel-carrying RLs between Singapore and Malaysian exercise areas. The later ad hoc UBREs therefore appear less as a sudden invention and more as the development of an existing pattern, using RL trucks, rigid tanks, pumps, filters, meters, hoses, local commercial support, and Petroleum Operator trade knowledge to create a mobile refuelling capability suited to New Zealand’s needs in Southeast Asia.
Exercise Taiha Tombak IX, 1987
The Taiha Tombak series provides a clearer sequence of NZAOD UBRE employment in the closing years of the New Zealand presence in Singapore. Two UBREs were sent on Exercise Taiha Tombak IX in 1987, conducted in Pahang State. Their use shows that, by 1987, the RL-mounted UBRE had moved beyond an occasional solution and had become part of the expected NZAOD support package for major exercises.
Taiha Tombak IX
With only a limited pool of NZAOD personnel available to support Exercise Taiha Tombak IX, soldiers were employed across multiple roles as required. At different stages of the exercise, Corporal Flo Tamehana and Lance Corporals Terry Read, Richard Tyler, and Rob McKie worked within the Petroleum Section. Their role was to operate the UBREs, handle fuel issues, maintain the dispensing equipment, and support kerbside or field refuelling as required by the exercise.
The exercise arrangement required repeated resupply runs to keep the UBREs filled. When operating in Johor State, this was normally achieved by returning to Singapore. However, when the exercises moved farther north up the Malay Peninsula, returning to Singapore was no longer practical. In those cases, fixed fuel sources were arranged through contracted commercial fuel companies, such as Mobil, using civilian service stations or commercial fuel points in or near the exercise area. In practical terms, the UBREs operated either as a shuttle-based bulk fuel link between Singapore and the deployed force, or as a mobile distribution system refilled from contracted civilian fuel infrastructure closer to the exercise.[2]
Exercise Pemburu Rusa, 1988
A further NZAOD detachment deployed on Exercise Pemburu Rusa in 1988 for approximately eight weeks, operating out of the Chaa Airfield area in Johor State. This confirms that UBRE use by NZAOD was not limited to the larger Taiha Tombak exercise series, but formed part of a wider pattern of field fuel support in Malaysia during the late 1980s.
The Petroleum Operators on Exercise Pemburu Rusa in 1988 were Lance Corporals Terry Read, Richard Tyler and Rob McKie. Their task was to keep the UBREs supplied and operational during the eight-week deployment, including repeated resupply runs from Chaa Airfield back to Singapore.
The exercise arrangement required repeated resupply runs from the exercise area back to Singapore to refill the UBREs. These were usually conducted as overnight trips. The fuel vehicles would leave the exercise area, complete the approximately two-hour road move back to Singapore, refuel overnight in barracks, and return to the exercise area the following morning. In practical terms, the UBREs were operating as a shuttle-based bulk fuel link between Singapore’s fixed support base and the deployed exercise area in Johor.
This routine again highlights the practical value of the RL-mounted UBRE, as well as the workload imposed on petroleum operators. They had to combine long-distance driving, refuelling, vehicle checks, field distribution, and ordinary detachment duties over an extended period. The UBRE was not just a piece of equipment, it was part of a daily sustainment rhythm connecting the depot base in Singapore with the deployed field force in Malaysia.
Exercise Taiha Tombak X, 1988
The operational value of these improvised UBREs is well illustrated by Exercise Taiha Tombak X, a brigade-size exercise conducted annually with the Malaysian Armed Forces in the states of Perak and Kedah. New Zealand involvement included 1 RNZIR, 141 Flight, the New Zealand Force Hospital, the New Zealand Military Police Unit, New Zealand Workshops, New Zealand Transport Squadron, and NZAOD. The NZAOD detachment was small, only fourteen personnel, but it carried a wide sustainment burden, including expendables, clothing, ammunition, water, POL, and rations.
The detachment’s Petroleum Section was central to the exercise. It consisted of Lance Corporals Terry Read, Rob McKie and “Monkey” Siemonek. Preparation began as early as March, with requirements being developed for the units to be supported during the exercise.
The move from Singapore to the exercise area took three days and covered approximately 800 kilometres. The Brigade Maintenance Area (BMA) moved first, followed by 1 RNZIR. At Tampin, the first overnight stop, the cooks established a kitchen while the petroleum operators refuelled the convoy. On that first night, two UBREs were emptied and then refuelled in the township of Tampin. The next day, as the BMA moved north towards Taiping, Terry Read and Monkey Siemonek remained behind to refuel 1 RNZIR, while Rob McKie left the convoy at Tapah and established a kerbside refuelling point just to top up vehicles so they could complete the move to Taiping.

This detail is important because it shows the UBREs doing exactly what they were intended to do: extending the force’s reach by allowing fuel to be staged, issued, replenished, and repositioned during a long road move. The vehicles were not simply carrying reserve fuel. They enabled movement over distance, supported a staggered convoy, and allowed different elements to be topped up at key points along the route.
Once the exercise began, based at an airfield in Taiping, the petroleum operators’ workload was relentless. The account records that the detachment worked up to twenty hours a day. A typical Petroleum Operator’s day began with stand-to half an hour before first light, followed by washing, breakfast, first parade of vehicles, and morning briefing from 0700 to 0900. From 0900 to 1900, the petroleum operators could be driving to Butterworth to refuel, conduct taskings, and carry out unit duties. From 1900 to 0300, they could be setting up distribution points deep in the exercise area.
The exercise also demonstrates that petroleum support was not limited to operating the pump. The Petroleum Section had to move with the force, establish distribution points, carry out long refuelling runs, maintain its own vehicles and equipment, and continue with ordinary unit duties such as camouflage, sentry duties, mess fatigues, rubbish duties, and defensive tasks. The UBRE was therefore part of a wider field routine, not a standalone technical asset.
The comparison with Malaysian refuelling practice is also revealing. The account describes Malaysian soldiers refuelling from a 3-ton Mercedes-Benz truck loaded with 44-gallon drums. A vehicle would pull alongside, fuel would be pumped from a rotary pump into a jerrycan, then emptied into the vehicle, with a soldier recording each 20-litre increment. Much of this was done by the light of a kerosene lamp.
This comparison highlights the relative efficiency of the New Zealand UBRE, improvised though it was. The New Zealand system was still crude by later standards, but its tank, pump, meter, filter, and hose arrangement allowed measured fuel to be issued directly from the vehicle.
The circumstances surrounding Exercise Taiha Tombak X also demonstrate the improvisational culture behind the system. For this large exercise, held in the vicinity of Taiping, three UBREs were to be provided by NZAOD. There were sufficient trucks and 2000-litre rigid tanks available, but only one serviceable pumpset in NZAOD. Replacement pumps sent from New Zealand arrived only the day before deployment.
With an open TY125 purchase order in place, the Petroleum team approached Fredie from Hong Teck Hin Hardware, a trusted local supplier used by the New Zealand Forces, and sourced suitable meters and filters.
One unit was assembled the night before deployment, while the other was built on the road at a refuelling rendezvous as the team waited for the battalion’s main body to arrive. Once mounted on the pumps, these modifications created compact dispensing units that were less prone to leaks or loose connections while driving.
That episode says much about the character of New Zealand Army logistics in Singapore during the late 1980s. The capability existed, but it relied on local initiative, trade knowledge, and the ability to solve practical problems quickly. The additional UBREs were not completed because the system was neither elegant nor well-resourced. It was completed because the soldiers involved understood what was needed, found the missing components, and made the equipment work in time for the exercise.
That improvisation was also a by-product of the early Petroleum Operator courses. With scarce equipment, much of it purchased in the late 1960s and by the late 1980s approaching twenty years of age, course time was often spent taking the equipment apart, reassembling it, understanding how the pumps, filters, meters, hoses, and fittings worked, and learning how to produce a workable dispensing pack from whatever was available. The term UBRE itself was not yet common Army language, but within the Petroleum Operator community, it became shorthand for a capability learned from British practice, adapted through coursework, and made practical with New Zealand equipment. This created operators who understood the equipment at a practical level, not just as users, but as soldiers capable of maintaining, adapting, and making it function on a shoestring.
Taiping Airfield Taiha Tombak X
In Singapore, that training culture proved decisive. When the exercise requirement exceeded the available complete sets, the solution was not to wait for a formal procurement process, but to identify the shortfall, source suitable commercial components locally, and integrate them into the third UBRE overnight. The photographs of local civilian fuel infrastructure and support activity reinforce the wider reality of NZAOD operations in Singapore. Military capability often depended on a close working knowledge of local suppliers, workshops, hardware stores, and commercial fuel facilities. In this environment, sustainment was not a neat separation between military and civilian systems. It was a practical blend of Army need, local knowledge, commercial availability, and the initiative of experienced ordnance soldiers.
It was a classic example of small-army improvisation, where formal requirements, limited holdings, ageing equipment, and operational deadlines met the practical ingenuity of the depot floor.
Kerbside refuelling and the return move
The return move from Taiping further demonstrates how the UBREs were used as a mobile refuelling chain. After the exercise ended, the detachment moved back to Taiping to join 1 RNZIR for the move back to Singapore. The Petroleum Operators again set up a kerbside. Once Terry Read and “Monkey” Siemonek’s trucks were empty, they refuelled and moved down the route to establish a kerbside at Tampins. Rob McKie completed refuelling at 2000 hours and then departed to set up another kerbside at Tapah.
The scale of the work was considerable. The first vehicles left Taiping at 0600 hours and were due at Tapah by 0800. At Tampins, Terry Read and “Monkey” Siemonek were busy from the arrival of the first vehicles and refuelled 120 vehicles. By the end of the exercise, the Petroleum Section had issued 55,000 litres of MT Gas. The same detachment also issued 48,000 litres of water, while general stores achieved 100 per cent demand satisfaction.
These figures convert the photographs from interesting images into a measurable logistics story. The UBREs were not incidental vehicles in the background of an exercise. They were central to moving the force, and their operators were responsible for tens of thousands of litres of fuel during long road moves, at field distribution points, and on return-route kerbsides.[3]
Exercise Taiha Tombak XI, 1989
In 1989, three UBREs again participated in Exercise Taiha Tombak XI. As in the previous year, Taiha Tombak X required long road moves, route replenishment, field fuel points, and repeated coordination between the deployed force and available fuel sources. This exercise was significant because it would be the final major exercise for NZAOD before the end of New Zealand’s permanent presence in Singapore.
By this stage, the RL-mounted UBRE was a proven, if imperfect, solution. Across several years of Malaysian deployments, it had supported long-distance movement, kerbside refuelling, field distribution points, route replenishment, and wider exercise sustainment. Although the equipment remained improvised, the method was by then well understood. Petroleum Operators knew how to assemble, check, move, refill, operate, account for fuel, and keep the system working under field conditions.
The Petroleum Operators supporting Taiha Tombak XI were Corporals Heather Thomas and Richard Tyler, and Lance Corporal Rob McKie. Their participation marked the endpoint of the visible NZAOD UBRE story in Malaysia. Its value lay not only in the equipment itself, but in the trade knowledge, local initiative, field routine, and hard-won experience built around it.
Topping up in Butterworth Taiha Tombak XI
Taiha Tombak XI was the last Malaysian exercise of this type for the NZAOD. By the end of 1989, New Zealand’s permanent force presence in South East Asia had drawn to a close, and the remaining New Zealand elements had redeployed from Singapore back to New Zealand. With that redeployment, a distinctive chapter in New Zealand’s post-war military logistics ended. For the NZAOD Petroleum Operators, the Malaysian UBRE deployments represented a small but important example of practical field logistics, where limited equipment, local adaptation, and experienced soldiers combined to sustain operations over distance.
Later Army Review and the Wider UBRE Problem
The NZAOD photographs and exercise accounts help explain why the Army became increasingly concerned about UBRE by the early 1990s. They show a capability that worked, but which depended heavily on adaptation, operator judgement, and equipment that had never become a fully purpose-designed military refuelling system.
Official correspondence from 1991 confirmed the problem. Army records described the existing UBRE as an ad hoc combination of equipment, much of it using items that had been in service since before 1975. The same review noted that the equipment was in poor repair, was unsafe, and failed to meet hazardous-substances transport requirements, although temporary waivers had been arranged.
By late 1991, UBRE had therefore become more than a practical refuelling asset. It had become a safety, capability-definition, and interoperability problem. Papers considered by the Army Capital Acquisition Management Committee noted that the existing UBRE had undergone an Army Maintenance Area Technical Services engineering review, which found “extremely serious safety hazards” in the equipment. The issue was not simply one of age or maintenance. The Army also lacked a clearly defined user requirement, with AST 57.2 identifying a nominal requirement for 20 UBRE sets but providing insufficient detail on the required characteristics or performance.[4]
Following the Army restructuring, this figure was questioned. Army Maintenance Area Technical Services estimated that ten to twelve refurbished sets might be sufficient, using the existing 2000-litre rigid tanks as the basis for a modified system. The preferred interim solution was pragmatic rather than ambitious. Instead of immediate replacement, which was expected to cost more than $60,000 per set, AMA Technical Services proposed refurbishing the existing tanks and replacing the hoses, connections, and associated equipment with safer and more suitable components at an estimated cost of $10,000 to $20,000 per set.[5]
The role UBRE was meant to fulfil remained significant. It was required for first-line resupply to units needing immediate bulk fuel replenishment when other methods were impractical or cost-ineffective. It was also required to provide kerbside refuelling facilities at second line, mobile bulk refuelling facilities for RNZAF helicopters supporting ground forces, and mobile bulk refuelling facilities for civil aid or emergency tasks in New Zealand and overseas.
At the same time, New Zealand was closely watching developments in Australia. The Australian Army was moving towards different UBRE systems for armoured and general-purpose wheeled requirements. For New Zealand, this raised a choice between adopting the Australian solution, including a separate RNZAC refuelling capability, or developing a modular New Zealand UBRE system while maintaining interoperability through standardised pumping and distribution equipment.
This context is important because the system’s shortcomings did not make it irrelevant. On the contrary, UBRE was essential because it filled a real operational need. It allowed petroleum operators to move beyond purely manual fuel distribution and gave commanders a more efficient means of sustaining vehicles, aircraft support, and mobile formations in the field.
Towards safer Unimog-mounted UBREs
By 1991, safety and legislative concerns had begun to force a more formal approach to UBRE mounting and carriage. The earlier RL-mounted arrangements had demonstrated their value in Malaysia. Still, they also exposed the weaknesses of carrying fuel tanks and dispensing equipment on open vehicle decks using improvised restraints. As transport and dangerous goods compliance became harder to ignore, the Army moved towards a more secure mounting system based on two 2000-litre rigid tanks carried on the deck of a Unimog.
To enable this, the original rigid tanks were modified from their earlier design. Reinforced forklift lifting channels were added, pressure relief valves were fitted, and the original gate valves were replaced with more modern ball valves. The mounting system allowed each 2000-litre tank to be tied down to the platform by screw-tightened rods, four per tank, providing a much more positive restraint than chains or straps. The whole platform was then secured to the Unimog with twistlocks, providing a safer, more controlled method of carriage.
.
Unimog UBRE, Ex Ivanhoe 1991
This represented an important step in the evolution of the New Zealand Army UBRE. The basic concept remained the same, a mobile bulk fuel system built around 2000-litre rigid tanks and a dispensing capability, but the method of securing the load had changed. The improvised logic of the RL-mounted UBRE was being replaced by a more engineered solution that better recognised the hazards of carrying flammable liquids over distance and across rough military routes.
This development did not immediately erase the earlier ad hoc systems. Instead, it marked the transition between the field expedients of the 1980s and the more regulated fuel-handling environment of the 1990s. The same small-army need remained, to move bulk fuel forward and issue it efficiently, but by 1991, the equipment was being reshaped by safety requirements, dangerous goods legislation, and the lessons learned from years of operating improvised UBREs in New Zealand, Singapore, and Malaysia.
The ad hoc UBRE would soldier on for another decade. Although safer mounting arrangements were introduced, the Army did not yet have a fully purpose-built replacement. As a result, the modified UBRE capability continued in service through the 1990s, bridging the gap between improvised field equipment and a formalised bulk refuelling system. That transition was finally completed in 2002, when the purpose-built Unit Bulk Refuelling Equipment Mk1 entered service, incorporating dedicated pumps, meters, and filters as part of a more deliberate and standardised capability.
For NZAOD in Singapore, this capability was particularly valuable. Exercises in Malaysia placed New Zealand vehicles and units into demanding tropical conditions, often operating away from fixed support facilities. Bulk fuel support had to be mobile, flexible, and responsive. The ad hoc UBREs shown in these photographs were therefore not curiosities. They were part of the everyday sustainment machinery that allowed New Zealand forces to train and operate in Southeast Asia during the final years of New Zealand’s long military presence in Singapore.
The images also speak to the professionalism of the Petroleum Operator trade. Operating this equipment was not simply a matter of turning on a pump. It required fuel-handling knowledge, an understanding of bonding and earthing, awareness of fire and environmental risks, pump operation, filter and meter management, hose discipline, vehicle-loading awareness, accounting discipline, and constant attention to leaks and loose fittings. In the absence of a purpose-designed system, safe operation depended heavily on the skill and judgement of the operators.
The options before the Army were therefore familiar small-army choices. Australian equipment offered a possible route to interoperability but raised questions about compatibility with New Zealand’s vehicle fleet and the need to support both A vehicles and B vehicles. Existing New Zealand equipment could be modified, but only at increasing cost and without fully resolving the underlying design limitations. The choice was whether to extend the life of an improvised but familiar capability, adopt an overseas design, or invest in a more suitable New Zealand solution.
These photographs capture the capability before that reassessment fully overtook it. They show UBRE in its late-1980s form, practical, rugged, improvised, and imperfect. They also show a period when New Zealand Army petroleum support was evolving from the older world of jerrycans, drums, and field expedients towards a more technical and regulated bulk fuel environment. In that sense, the ad hoc UBREs used by NZAOD in Singapore and Malaysia were transitional equipment. They belonged to an era when sustainment capability was often created through adaptation, local initiative, and trade knowledge.
Current NZ Army UBRE
Their importance lies in that very imperfection. They remind us that logistics history is not only about formal establishments, new equipment projects, or official doctrine. It is also about the equipment that soldiers actually used, the compromises they managed, and the practical systems that kept vehicles moving, exercises running, and commanders supported. Between 1985 and 1989, on Malaysian roads, in jungle hides, at temporary fuel points, and beside civilian fuel infrastructure, these ad hoc UBREs did exactly that. Their continued operation into the 1990s and eventual replacement by the Unit Bulk Refuelling Equipment Mk1 in 2002 confirm their place as an important bridge between improvisation and modern military fuel distribution.

Weapons, Ammunition, and the Limits of Capacity in New Zealand, 1941–1944
One of the clearest ways to understand the scale of New Zealand’s 1939-1944 wartime transformation is not through unit establishments or organisational charts, but through the arithmetic of weapons and ammunition.
In 1941, the Army was small, lightly equipped, and operating within clear limits. By 1944, it had become something very different, a force holding thousands of weapons and millions of rounds of ammunition, supported by a nationwide network of depots and storage sites built at speed and under pressure.
At first glance, this appears to be a straightforward story of expansion. More guns, more ammunition, more infrastructure, a system growing to meet the demands of war.
But the detail tells a more complex story.
The Quartermaster-General’s report of 1944 provides a rare snapshot of that transformation. Using mid-1941 as a baseline and March 1944 as an endpoint, it shows not just what New Zealand held, but how rapidly it had to build the system to support it. Weapons were introduced faster than they could be standardised. Ammunition accumulated faster than it could be comfortably stored. Infrastructure expanded, but rarely kept pace.
Running through all of this was a constraint that was less visible but more decisive.
Not space. Not supply. Risk.
Even at the height of expansion, the system was not defined by how much it could hold, but by how safely it could manage what it contained.
Understanding Hazard: The Historical Foundations
The classification of ammunition by hazard category and group behaviour did not emerge fully formed during the Second World War. It was the product of decades of experience across the British and wider imperial ammunition system.
From the late nineteenth century onwards, a series of catastrophic explosions in magazines, depots, and aboard ships forced armies to confront a simple reality: ammunition did not merely burn, it behaved differently depending on its composition, confinement, and quantity. In some cases, a local incident could escalate rapidly through sympathetic detonation, producing catastrophic effects.
By the First World War, this understanding had become embedded in British ordnance practice.
From Experience to Principle
By the interwar period, British ammunition doctrine, which New Zealand inherited directly, had already established a set of hard-learned principles shaped by decades of accidents, battlefield experience, and industrial mishaps.
These included:
Separation of explosives by type, particularly detonators, propellants, and filled shells
Limitation of quantities per magazine, based not on space but on explosive effect
Dispersal of stocks, to prevent a single incident destroying an entire reserve
Recognition of sympathetic detonation, where one explosion could trigger another
Central to these principles was what would later be formalised as Net Explosive Content (NEC).
NEC represents the actual weight of explosive material, not the number of rounds. In practical terms, it provided a way to measure risk. A simple comparison illustrates this:
A single 3.7-inch anti-aircraft round contained a significant high explosive charge, meaning that thousands of such rounds could reach the safe explosive limit of a magazine. By contrast, millions of small arms rounds could be stored without approaching the same threshold.
This distinction mattered. Storage was not governed by how much could be stacked, but by how much explosive effect could be safely contained.
Although the term itself was not always used explicitly in this period, the concept was clearly understood. Magazine limits, spacing distances, and storage policies were already being determined by the total explosive effect that could be safely contained, rather than by available space.
Taken together, these principles map directly to what would later become:
Hazard categories (local versus mass explosion effects)
Compatibility groups (what can safely be stored together)
Net Explosive Content (NEC) limits (how much explosive risk can be safely held in one place)
The Emergence of Category and Group Thinking
By the 1940s, these ideas had been codified in practical terms. CAT X, Y, and Z were the standard hazard classifications used to categorise ammunition hazards:[1]
CAT X (local hazard)
CAT Y (intermediate hazard)
CAT Z (mass explosion hazard)
These categories reflected a long-standing recognition that:
Some ammunition would burn locally
Some would produce blast and fragmentation
Some could detonate in its entirety
Alongside this, British and Dominion forces employed a formal classification system set out in the Classified List of Government Explosives, which defined ammunition by composition, sensitivity, and function.[2]
Government Explosives Groups (Full Classification)
Group 1: Explosives bearing a fire and explosion risk, relatively sensitive to spark or friction, or requiring lead-free conditions, not containing a means of ignition.
Group 2: Explosives liable to decomposition, bearing an explosion risk and capable of functioning by spark or friction, but not containing a means of ignition.
Group 3: Explosives liable to decomposition, presenting primarily a fire risk, and not containing their own means of ignition.
Group 4: Stable explosives presenting a fire or explosion risk, but not containing their own means of ignition.
Group 5: Unboxed shell filled with high explosive, gunpowder, or similar compositions, plugged or fuzed.
Group 6: Boxed ammunition containing high explosive, gunpowder, or propellant, with or without its own means of ignition.
Group 7: Mines, bombs, and underwater ammunition filled with high explosive, plugged, with or without components.
Group 7A: Mines, bombs, and underwater ammunition filled with high explosive and containing their own means of ignition.
Group 8: Mortar and projector ammunition, grenades, and rockets, filled with high explosive or gunpowder, with or without propellant and components.
Group 9: Pyrotechnics, including signalling, illumination, and similar stores.
Group 10: Detonators and initiatory compositions, representing the most sensitive class of explosives.
Group 11: Incendiary and smoke ammunition not containing phosphides, white phosphorus, or flammable liquids.
Group 12: Ammunition containing phosphide or white phosphorus, presenting increased fire and chemical hazard.
Group 13: Chemical ammunition, including toxic or reactive fillings.
Group 14: Special group applicable to naval (H.M. ships) stowage conditions.
Group 15: Incendiary ammunition containing flammable liquids or gels, but not phosphorus.
This system defined what the explosive was. The CAT X/Y/Z system defined what it did in bulk.
From Composition to Behaviour
The interaction between these systems was central to wartime storage:
Group 5 and 7 natures typically aligned with CAT Z, driving magazine limits
Group 6 and 8 natures aligned with CAT Y, forming the bulk of operational stocks
Group 9 and some Group 11 natures aligned with CAT X, presenting mainly fire hazards
Group 10 detonators required strict segregation regardless of quantity
What emerges is a layered system:
A System Understood, but Defined by Limits
By the time of the Second World War, British and Dominion forces, including New Zealand, were operating within this framework in practice, even if the terminology had not yet been fully standardised.
What mattered was not the labels, but the underlying logic: Ammunition storage was governed not by how much space was available, but by how much explosive risk could be safely contained.
This distinction, already understood before the war, would become critical as New Zealand’s ammunition holdings expanded dramatically after 1942.
A Force Built on Scarcity
In mid-1941, New Zealand’s position was defined by limitation. Equipment existed, but in constrained quantities, and often of obsolescent types.[3]
At the end of 1941, New Zealand possessed just 164 artillery pieces of all classes.
Ammunition holdings reflected the same reality. Total gun ammunition stocks stood at 108,299 rounds, sufficient for training and limited contingencies, but not for sustained operations.
This was not a failure; it was a priority. New Zealand sat low in the imperial allocation system, and much of what it required existed on paper rather than in depots.
Yet even at this early stage, the nature of the ammunition held imposed constraints that were not immediately visible in the headline numbers.

At first glance, these figures reinforce the impression of scarcity, limited guns, modest ammunition stocks, and a force not yet configured for large-scale war. But read more closely, they reveal something more important.
The distribution of ammunition was uneven, and that unevenness mattered. Field artillery sat broadly within a band of 300 to 750 rounds per gun, reflecting a balance between capability and constraint. Coast artillery, while lower in rounds per gun, involved larger calibres and fixed locations, concentrating risk geographically. It is, however, the anti-aircraft line that stands apart with over 22,000 rounds held for just four guns. Taken together, these figures point to a subtle but important conclusion.
While the number of guns was small, the ammunition required to sustain them already imposed technical and safety constraints on the system. Storage was not simply a matter of space, but of how much explosive weight could be safely contained, how it was distributed, and how it could be managed.
In effect, even before the 1942 surge, the ammunition system was operating within the limits of explosive risk. This was not yet a crisis. But the conditions were already set, and the expansion that followed would not introduce complexity. It would multiply it.
The Shock of 1942: Demand Without Precedent
The entry of Japan into the war in December 1941 transformed the situation overnight.
Mobilisation surged. By mid-1942, New Zealand forces peaked at over 121,000 personnel, with roughly 200,000 troops in New Zealand when the Home Guard is included, all requiring equipment, weapons, and ammunition.[4]
The requirement was no longer incremental growth, it was exponential expansion, and the system responded.
Between July 1941 and March 1944, New Zealand received 2,507 artillery pieces. Modern field artillery supplemented rather than replaced obsolescent systems, resulting in a mixed and transitional inventory shaped as much by availability as by design.
At the outset in mid-1941, New Zealand’s field artillery reflected a largely First World War-era structure, including:
BL 60-pounder Mk I (6)
BL 60-pounder Mk I
BL 6-inch 26-cwt howitzer (14)
BL 6-inch 26-cwt howitzer
18-pounder QF Mk II field guns (60)
18-pounder QF Mk I field guns
3.7-inch howitzers (9)
3.7-inch howitzer
4.5-inch howitzers (19)
4.5-inch howitzer
Between 1941 and 1944, new equipment was introduced in significant numbers, most notably:
Ordnance QF 25-pounder Mk II (255 received), which became the core field artillery system
25-pounder (18/25-pdr conversions) (12)
155mm M1917A1 guns (26 received, 12 retained)
At the same time, older systems were not immediately withdrawn. Instead, they were retained and, in some cases, augmented:
18-pounders increased from 60 to 104
6-inch 26-cwt howitzers increased from 14 to 18
4.5-inch howitzers increased from 19 to 27
Additional equipment further complicated the inventory with Italian weapons captured in North Africa impressed into service for home defence:
Cannone da 77/28 Modello 05 (14 received, 10 held)
Cannone da 65/17 Modello 13 (17 received and retained)
Other systems, such as the 75mm pack howitzer (37 received), appear not to have been retained in New Zealand holdings, reflecting redistribution or operational allocation elsewhere.
This was not a clean transition from old to new. It was an accumulation driven by urgency, resulting in a heterogeneous mix of legacy, modern, and foreign-pattern equipment.
Alongside this, large numbers of anti-tank weapons were introduced, reflecting the growing importance of anti-armour defence across both home defence and expeditionary roles. This included the Ordnance QF 2-pounder and QF 6-pounder anti-tank guns, which formed the backbone of towed capability, supported by infantry-operated systems such as the Projector, Infantry, Anti-Tank (PIAT) and the Rifle, Anti-Tank, .55-inch Boys. These were further reinforced by a wide range of munitions, including rifle grenades and substantial stocks of anti-tank mines.
At the same time, there was a dramatic expansion in anti-aircraft capability, from just 4 guns in 1941 to 770 received within 12 months. This comprised a mix of heavy and light systems, including approximately 300 3.7-inch heavy anti-aircraft guns, forming the backbone of high-altitude defence, and around 470 40mm Bofors systems designed to counter low-level and fast-moving aircraft.
What makes this expansion particularly striking is not simply the increase in numbers, but the scale and diversity of the system that accompanied it. Anti-aircraft defence required not just guns, but:
Large quantities of high explosive, time-fuzed, and specialised ammunition
Fire control equipment, including predictors and, later, radar integration
Trained crews capable of sustained high-rate firing
Unlike field artillery, anti-aircraft weapons consumed ammunition at significantly higher rates. Even a single engagement could see a battery expend thousands of rounds. Scaled across hundreds of guns, this created an immediate and substantial demand on ammunition stocks, storage capacity, and distribution systems.
The increase from 4 to 770 guns was not simply numerical; it introduced one of the most ammunition-intensive and explosive-heavy systems within the New Zealand logistical structure.
By March 1944, holdings stood at 2,279 pieces of equipment, even after disposals and transfers. This was not simply growth. It was the rapid modernisation of an entire force.[5]
Ammunition: The True Weight of War
If weapons represent capability, ammunition represents sustainability.
From a baseline of 108,299 rounds, New Zealand received 4,614,189 rounds of artillery ammunition between July 1941 and March 1944. By March 1944, total artillery holdings had reached 4,722,488 rounds, spanning:
28 calibres
47 distinct types, including high explosive, armour-piercing, semi-armour piercing, smoke, chemical, and other specialised natures
This expansion was closely tied to the rapid growth in weapon systems, particularly anti-aircraft and anti-tank artillery.
The increase from just four anti-aircraft guns in 1941 to 770 within 12 months was matched by a corresponding surge in ammunition holdings. By March 1944, anti-aircraft ammunition alone had reached substantial levels, including:
428,023 rounds of 3.7-inch heavy anti-aircraft ammunition
608,984 rounds of 40 mm ammunition
22,639 rounds of 3-inch 20-cwt ammunition
26,400 rounds of 37 mm ammunition
Taken together, this represents more than 1 million rounds of anti-aircraft ammunition, a scale that far exceeded the holdings of many individual field artillery natures.
But anti-aircraft ammunition was only one part of the picture. New Zealand had also accumulated very substantial holdings of anti-tank ammunition. By March 1944, stocks included:
650,997 rounds of Ordnance QF 6-pounder ammunition
423,259 rounds of Ordnance QF 2-pounder ammunition
791,043 rounds of 37 mm anti-tank ammunition
Together, these amounted to 1,865,299 rounds of dedicated anti-tank gun ammunition. This was a remarkable figure, reflecting the central place anti-tank defence had assumed in modern war. Unlike older artillery systems, anti-tank weapons were expected to be held ready for sudden, intense action, often at short notice and in dispersed positions. Their ammunition, therefore, imposed not merely a storage burden, but a readiness burden across the whole logistics system.
Tank-related ammunition added a further layer of scale. Armoured fighting vehicles and associated weapons drew upon large quantities of machine-gun ammunition, particularly for Besa 7.92 mm guns, of which holdings reached:
215,500 rounds of Besa 7.92 mm Ball
3,690,000 rounds of Besa 7.92 mm Ball and Tracer
2,336,000 rounds of Besa 7.92 mm Ball, Tracer, and AP
This gave a combined total of 6,241,500 rounds of Besa ammunition alone. To this can be added 521,000 rounds of Boys .55-inch armour-piercing ammunition, showing that anti-armour defence still extended beyond gun systems into older infantry anti-tank weapons.
At the infantry level, anti-tank holdings were also substantial. Stocks included:
Significant holdings of anti-tank mines, including 55,000 Mark II, 39,000 Mark V, 19,000 Local Pattern, and 7,200 M1A1 mines
These figures show that anti-tank capability was not confined to specialist guns. It was distributed across the force, from artillery and armoured units to infantry and field defences. In practical terms, this meant that anti-tank ammunition had to be stored, handled, moved, and issued across a much wider range of locations and unit types than many conventional artillery natures.
What makes this particularly significant is not just the quantity, but the nature of the ammunition itself. Anti-aircraft and anti-tank rounds were predominantly high-explosive, armour-piercing, or fused, designed for rapid, sustained fire under combat conditions. Much of this ammunition possessed what would now be recognised as high-hazard or mass-explosion characteristics. Unlike field artillery, where expenditure could be episodic, anti-aircraft and anti-tank systems were designed for immediate response to fast-moving threats. Even limited operational activity could consume large quantities of ammunition. Scaled across hundreds of guns, armoured vehicles, and infantry anti-tank weapons, this created an immediate and sustained demand on:
ammunition production and supply
storage capacity and magazine limits
handling, transport, and distribution systems
The expansion of anti-aircraft, tank, and anti-tank capability did not simply add to the total volume of ammunition. It introduced some of the most explosive-intensive, logistically demanding, and operationally sensitive natures within the entire system.
This helps explain why, despite the overall scale of artillery ammunition holdings, the distribution and behaviour of specific natures, particularly anti-aircraft, anti-tank, and other high explosive stocks, mattered far more than the total number of rounds.
This was not passive stock. New Zealand actively sustained operations, issuing over 839,000 rounds to Pacific forces. The scale is striking. But even this does not fully capture the weight of the system.
Beyond Artillery: The Full Ammunition Burden
Artillery ammunition formed only one part of a much larger inventory. By 1944, New Zealand was holding:
Hundreds of millions of rounds of small arms ammunition, including .303, .300, 7.92 9mm, and .45
Millions of mortar bombs and grenades, across multiple calibres and natures
Large stocks of anti-tank mines and infantry munitions
Substantial quantities of bulk explosives, including gelignite, ammonal, and monobel
Hundreds of thousands of detonators, fuzes, and explosive accessories
Taken together, this represented not just an increase in scale, but a transformation in the structure of the ammunition system.
Quantity Versus Risk
At first glance, the system appears dominated by sheer volume, particularly small arms ammunition, which alone ran into the hundreds of millions of rounds. Yet this volume was deceptive.
Small arms ammunition, despite its quantity, sat largely within what would now be understood as low-hazard categories, contributing relatively little to overall explosive risk.
By contrast, a much smaller proportion of holdings, particularly:
Artillery high-explosive ammunition
Anti-aircraft ammunition
Mortar bombs and grenades
Bulk explosives and demolition stores
carried significantly greater explosive weight and hazard.
These natures, which broadly align with mass-explosion characteristics, were the true drivers of risk within the system. What emerges is a clear distinction between:
The largest part of the system by quantity was small arms ammunition
The most significant part of the system by risk, high explosive and sensitive stores
In practical terms, this meant:
Storage capacity was not defined by how much could be physically held
It was defined by how much explosive hazard could be safely contained
A relatively small proportion of ammunition types effectively dictated the limits of the entire system, shaping:
Magazine design and spacing
Storage allocation
Handling and transport procedures
By 1944, New Zealand’s ammunition system had expanded to a scale that would have been unimaginable in 1941. Yet it remained constrained, not by shortage, but by the characteristics of the ammunition itself.
The true weight of war was not measured in the number of rounds held, but in the explosive risk carried by a small proportion of them.
Ammunition Infrastructure: Building a System to Carry the Weight
The rapid expansion in ammunition holdings between 1941 and 1944 did not occur in isolation. It drove a parallel transformation of New Zealand’s ammunition infrastructure, shifting it from a small, centralised network into a dispersed, nationwide system designed to manage both scale and risk.
Before the war, ammunition storage in New Zealand was limited in capacity and geographically concentrated. Facilities at Fort Balance, Ōhakea, and Hopuhopu reflected peacetime requirements, designed to store, inspect, and maintain relatively modest stocks. They were not intended to support a rapidly expanding force preparing for sustained operations at home and overseas.
From 1939, and particularly after 1941, this system came under immediate and sustained pressure. As new weapons and ammunition arrived in increasing quantities, existing magazine capacity was quickly exceeded. At the same time, responsibility for ammunition shifted toward a more specialised ordnance system, requiring a corresponding expansion in personnel, facilities, and technical oversight.
This pressure was not only physical. It was organisational.
A minute by the Quartermaster General, dated 12 October 1941, provides a clear snapshot of the ammunition organisation at the point when expansion was beginning to accelerate. At that time, the entire ammunition system was supported by a remarkably small workforce.[6]
Military personnel consisted of:
1 Captain
1 Lieutenant
1 Staff Sergeant
2 Corporals
These were supported by 12 civilian staff, comprising:
10 civilians at Fort Ballance
2 civilians at the Waikato magazines
In total, the national ammunition organisation was being sustained by just 17 personnel.
This was, in effect, a peacetime structure attempting to absorb a wartime influx. The system’s operational level remained heavily dependent on civilian labour, while military oversight was limited to a small supervisory cadre.
The implications were immediate. Ammunition was arriving in increasing quantities, magazine construction was expanding, and responsibilities were growing to include inspection, repair, preservation, accounting, and safe custody across multiple locations. Yet the manpower to manage this system remained minimal.
The response, as reflected in the same documentation, was an urgent move to expand and militarise the ammunition organisation. Civilian staff were to be replaced, and a dedicated military establishment was to be created to operate within camps, fortress areas, and dispersed magazine sites.
This moment marks a critical transition. By late 1941, the constraint on New Zealand’s ammunition system was no longer simply one of supply or storage. It was organisational. The system had reached the limits of what a small, peacetime manpower structure could sustain.
A Distributed National System
By the height of the war, New Zealand’s ammunition system had evolved into a layered structure:
Primary depots holding bulk reserves
Sub-depots and forward storage sites supporting regional forces
Inspection and repair facilities ensuring serviceability
Transport systems linking depots to operational units
This network extended across both islands. In the north, Ardmore, Hopuhopu, and Kelm’s Road formed key nodes. In the central districts, Waiouru and Makomako supported training and mobilisation. Around Wellington, Trentham and Belmont provided access to major ports. In the south, Glentunnel, Mount Somers, Fairlie, and Alexandra formed a dispersed magazine system supporting both storage and distribution.
Alongside Army facilities, RNZAF and naval ammunition depots were significantly expanded, developing into large, specialised sites with multiple magazines and dedicated handling infrastructure.
What emerged was not simply a collection of storage locations, but an integrated national system designed for distribution, dispersal, and continuity under pressure.
From Storage to Risk Management
This expansion marked a fundamental shift in approach. Pre-war ammunition storage had relied on centralisation, limited magazine numbers, and relatively small holdings. Wartime conditions made that model untenable.
In its place, a new system was implemented based on established ordnance principles:
Dispersal of stocks across multiple locations
Separation of hazardous natures
Increased spacing between magazines
Strict limits on explosive quantities per site
These measures were not new in theory, but the scale at which they were applied in New Zealand during the war was unprecedented. Storage was no longer simply about capacity; it was about controlling the effects of failure. Distance, separation, and containment became the primary tools for managing the risk of fire and sympathetic detonation.
Built Under Pressure, Proven Under Load
The expansion of ammunition infrastructure from 1941 onward was the result of a deliberate construction programme directed by Army Headquarters following War Cabinet approval. It reflected both the scale of wartime demand and a clear understanding that ammunition posed a distinct and enduring hazard.[7]
New magazine areas were established in locations selected for their ability to balance access with safety, often remote, dispersed, and deliberately concealed. Sites such as Ardmore, Waiouru, Makomako, Belmont, and Glentunnel were developed with these principles in mind.
Construction was carried out under persistent constraints. Difficult terrain, poor weather, and manpower shortages slowed progress, and in some cases ammunition stocks accumulated faster than permanent facilities could be completed, requiring temporary storage in the open. Despite these pressures, the underlying design principles were consistently applied:
magazines separated by distance
explosive quantities strictly controlled
traverses constructed to contain blast
depots dispersed to prevent catastrophic loss
This was not a system designed to eliminate risk, that was never possible. It was a system designed to manage it, absorb it, and prevent local incidents from becoming national disasters.
Its effectiveness would ultimately be demonstrated under operational conditions on 26 February 1945.
Glentunnel Ammunition Area 1943
At Glentunnel, one of the South Island magazine areas constructed as part of this expansion, an accidental explosion destroyed Storehouse No. 10 and its contents. The detonation was complete, reducing the building to debris.[8]
Yet despite the scale of the explosion, there were no casualties, and, more importantly, no propagation beyond the single magazine.[9] Adjacent storehouses remained intact, and no sympathetic detonation occurred.[10]
As later recorded in official accounts, this was the only storehouse lost to an accidental explosion during the period, and it demonstrated the effectiveness of traversing.
This outcome was not incidental. It was the direct result of the system described above.
Glentunnel Depot 1956, arrow indicating ESH 10
Magazines at Glentunnel had been excavated into the hillsides, arranged in sequence, and separated by earth traverses designed to absorb and deflect blast effects. The loss of one storehouse, while total at the local level, was contained at the system level.
Set against the wider wartime experience, where ammunition accidents could destroy entire depots, the distinction is clear. Where other systems failed through sympathetic detonation, Glentunnel did not.
What this demonstrates is fundamental. The constraint governing ammunition storage was not space, but risk.
The infrastructure built between 1941 and 1944 was not simply an expansion of capacity. It was a system engineered to ensure that when failure occurred, it remained localised.
Glentunnel provides a rare and definitive example that this system worked.
A System Built for Scale, But Constrained by Hazard
Despite the rapid expansion of infrastructure, capacity never fully aligned with demand.
The planning behind this expansion was itself a significant ordnance achievement. The allocation of space, calculation of permissible explosive limits, and matching of ammunition types to suitable storage were all undertaken without the benefit of modern ERP systems, digital inventory tools, or automated hazard-management software. Instead, this work fell to the small Inspecting Ordnance Officer staff, operating under the Chief Inspector of Munitions and Chief Inspecting Ordnance Officer, Lieutenant Colonel I. R. Withell. Their calculations relied on manual returns, local storage data, and technical information drawn from the latest Ammunition Bulletins issued by the Chief Inspector of Armaments in the United Kingdom and dispatched to New Zealand. In practical terms, the wartime ammunition storage system was built not only with concrete, timber, earthworks, and labour, but also through painstaking clerical discipline, technical judgement, and professional ordnance expertise.
By 1944, the manpower required to sustain this system reflected the scale of the transformation that had taken place since 1941.
As at 31 March 1944, the Ammunition Section and associated repair elements comprised an establishment of 159 personnel, with an actual strength of 150. The organisation was now distributed across Army Headquarters and the Northern, Central, and Southern Districts, with a dedicated Ammunition Repair Section responsible for inspection and maintenance.
In total, the system was supported by 10 officers and 140 other ranks.
This stood in stark contrast to October 1941, when the entire ammunition system had been sustained by just a handful of military personnel supported by civilian labour. What had emerged by 1944 was a fully militarised and professionalised organisation capable of managing both the scale and the risk inherent in modern warfare.
At the outset of the war, New Zealand possessed just 13-gun ammunition magazines, largely concentrated in a small number of established sites.[11] These were sufficient for pre-war holdings, but wholly inadequate for the scale of expansion that followed.
By March 1944, this had grown to:
351 ammunition magazines distributed across the country
A total storage capacity of approximately 2¾ million cubic feet
This represents not just growth, but a transformation from a centralised, peacetime system into a dispersed, national network of ammunition storage and handling facilities.
Yet even this expansion did not resolve the underlying constraint.
As large volumes of ammunition, particularly high explosive and anti-aircraft stocks, entered the system:
Magazine capacity was limited by Net Explosive Content (NEC) thresholds, not physical space
Safety distances between magazines imposed hard limits on how much could be held at any one site
In practical terms, a depot could appear only partially full yet already be at its safe operating limit. At peak inflow, this tension was evident:
Ammunition was temporarily stored in the open and would remain a feature or many depots well into the post-war years
Stocks were frequently redistributed between sites
New magazine construction struggled to keep pace with arrivals
Even by the end of the war, the system remained under pressure. The return of ammunition from overseas, combined with retained reserves and the steady recovery of ammunition from disbanded and demobilising Home Defence units, quickly absorbed any remaining capacity.
The Quantitative Reality
The numbers tell the story clearly:
Yet the expansion in infrastructure did not translate into unlimited storage.
Because:
A relatively small proportion of ammunition, particularly CAT Z, Groups 5 and 7 high explosive natures, consumed a disproportionate share of allowable capacity
Lower-risk ammunition, such as small arms, occupied space but contributed little to the overall hazard
New Zealand built hundreds of magazines to store its wartime ammunition. In the end, it was not space that defined the system, but the limits imposed by explosive risk.
Lessons from Expansion
Looking back over the period from 1941 to 1944, what stands out is not just how much New Zealand built, but how the system actually behaved under pressure.
At the beginning, the problem appeared straightforward. There was not enough, not enough guns, not enough ammunition, not enough capacity. By 1944, that problem had been solved. New Zealand held more weapons, more ammunition, and more infrastructure than anyone in 1941 could reasonably have imagined. Yet the pressure never truly went away.
The reason lies in a constraint that was less visible, but more decisive. The system was never limited by how much it could hold. It was limited by explosive risk. More magazines could be built, depots expanded, and stocks redistributed, but the underlying characteristics of the ammunition could not be changed. That constraint remained constant, regardless of scale.
The expansion itself was not linear. New equipment arrived, but older systems were not immediately replaced. Instead, they remained in service, supplemented rather than withdrawn. The result was a heterogeneous force, combining First World War-era guns, modern British equipment, and whatever could be obtained under wartime conditions. The same pattern is evident in the ammunition, where diversity increased alongside volume.
On paper, the system appears enormous, particularly when small arms ammunition is included. Yet this volume is misleading. The majority of rounds sat within comparatively low-risk categories. The real constraint lay in a much smaller proportion of high-explosive and sensitive natures. These dictated how the entire system had to be organised, stored, and managed.
Before the war, ammunition could be held in a small number of centralised locations. By 1944, it had to be dispersed across the country. This was not simply a matter of efficiency or expansion. It was a matter of survivability. A failure at one site could not be allowed to compromise the entire reserve. Dispersion was therefore not optional, it was essential.
Even then, the system remained under constant pressure. Construction struggled to keep pace with inflow. Ammunition was stored in the open, stocks were redistributed between sites, and depots that appeared only partially full were already at their safe operating limits.
Use added a further layer of complexity. Some weapons remained largely static within the system. Others did not. Anti-aircraft weapons, in particular, transformed the problem. Their rate of expenditure turned stockpiles into flow systems, where sustainability depended not only on what was held, but on how quickly it could be replaced.
What is perhaps most revealing is that the pressure did not end with the war. As units demobilised and overseas stocks returned, the system was required to absorb them. What had once been a problem of shortage became a problem of accumulation. The infrastructure that had struggled to manage inflow now had to accommodate return and retention.
Seen in this light, the story is not one of shortage followed by surplus, but of balance.
New Zealand built a system capable of sustaining a modern force, supporting overseas operations, and managing vast quantities of ammunition. But it never escaped the limits imposed by the nature of what it held.
In the end, the system was not defined by how much it could store, but by how safely it could manage its contents.

Fred Kreegher and the 2 NZEF Ordnance Field Park, 1941–1944
Fred Kreegher served for forty-three months with the 2nd New Zealand Division Ordnance Field Park (OFP), from its formation in the Western Desert in 1941 through to the Italian campaign in 1944. Of that service, very little survives.
There are photographs, a scattering of names, and a sequence of locations that trace his movement across North Africa, the Middle East, and into Italy. But there is no personal diary, no letters that describe the experience, and no narrative in his own words that explains what those years meant or how they were lived. What remains instead is the record of the system he served within.
Lemon Squeezer as worn my members of the 2nd NZEF NZOC, 1939-44.
The war diaries of the Divisional OFP provide a continuous, if impersonal, account of daily activity, movements, shortages, recoveries, and adaptation under pressure. They do not describe Kreegher directly, but they describe, in detail, the work he was part of, the environment he operated in, and the conditions that shaped his service. This account draws on those records.
It presents a month-by-month reconstruction of events within the OFP, with gaps where no diary survives, and uses them to build an interpretative narrative of Kreegher’s service. It does not attempt to recreate his personal voice, which is lost, but instead situates him within the system that defined his war.
That system was central to the way the 2nd New Zealand Division fought. From Greece and Crete, through the desert war, El Alamein, the advance across North Africa, and into Italy, the Division operated as a highly mobile formation dependent on vehicles and equipment, and on continuous resupply. Its effectiveness relied not only on combat units but on the ability of its supporting elements to sustain movement, recover losses, and adapt across multiple theatres.
The OFP was part of that capability. Its role was not simply to hold stores, but to ensure that the Division’s workshops had the parts required to keep vehicles running, weapons functioning, and units operational. It operated forward, often close behind the fighting troops, and its work expanded or contracted with the tempo of operations.
For men like Kreegher, the war was experienced not through set-piece battles alone, but through the continuous demands of that system. Checking, loading, issuing, recovering, and accounting, carried out in camps, in convoys, at roadheads, and under fire.
This account reconstructs that experience as closely as the surviving record allows. It follows the movement of the system, and places Kreegher within it, not as an observer, but as one of the men who made it work.
Because while his individual voice is absent, the system he served in leaves a clear trace. And through it, his war can still be understood.
The photographs that accompany this account have been kindly provided by Fred’s family. Some are captioned, while others are not. Several appear to be personal photographs taken by Fred and his colleagues, while others are images that could be purchased by servicemen in theatre. Where possible, these images have been integrated into the narrative to support the account. Those that could not be confidently placed have been included in a gallery at the end.
Nothing Stays Still
Ferdinand Charles Kreegher was not, at first glance, the sort of man who seemed destined for war.
He was born on 21 October 1911 at Cunninghams, a small farming district in the Kiwitea country north of Feilding in the Manawatu, and by the late 1930s had settled into a life that was orderly, predictable, and rooted in routine. By 1938, he was working as a clerk with Dalgety & Company at their Kaikohe branch, part of a business that sat at the centre of rural New Zealand’s commercial life.
It was steady work, built on records, accuracy, and trust, the careful management of goods, accounts, and relationships.
Outside of work, he was part of the local community. A volunteer firefighter who was awarded the United Fire Brigades Association Long Service medal for five years of service.
He was also a keen golfer, with newspaper notices regularly placing him on the golf course, a familiar name in club competitions and results columns, and a photo of his collection showing one of his trophies.
It was a life that followed a rhythm: work, community, sport. A pattern that made sense and required no explanation, nothing in it suggested what was coming.
When war came, it did not immediately overturn that world, but it began to pull at it.
Kreegher enlisted in July 1940, his name appearing among those from Northland stepping forward for service. At that stage, the war still carried a sense of distance. There remained an unspoken hope that it might be contained or at least understood in familiar terms. But by the time he mobilised with the 5th Reinforcements and trained at Papakura, that distance had already begun to close. The war was no longer something observed; it was something entered.
Leaving New Zealand aboard the Mauretania on 1 April 1941, Kreegher moved from a known world into one already under strain.
By the time he disembarked in Egypt on 15 May 1941, he was not arriving at the beginning of a campaign, but into the aftermath of Greece and Crete, where the New Zealand Division was rebuilding itself after hard fighting and heavy losses. At first, he was absorbed into the rear of the system, posted to a Base Ordnance Depot.
There, the work would have looked familiar in structure, records, stock, and controlled issue, but on a scale that dwarfed anything he had known before. It was orderly, but distant, with his thoughts recorded in a letter home to his parents in Taihape.
In August, he moved forward and stepped into the New Zealand Divisional OFP, something very different.
The Divisional OFP had only just been formed in July 1941. It was a response to a changing kind of war, one that depended on vehicles, machinery, and constant movement.
Organised with a headquarters and three sections, its purpose was not simply to hold stores, but to keep the Division moving by supplying the spares its workshops needed, wherever they were operating. It was, in effect, a system designed for motion, and when Kreegher joined it, it was still learning how to work.
September 1941 – “Routine work.”
At Bagush, it appeared settled. Stores were checked, vehicles maintained, and inspections carried out. The diary records it all in the language of routine, a steady sequence of tasks completed as expected, but beneath that surface, it was still forming.
Loads were shifted and reshaped
Vehicles repacked and reorganised
Orders arrived, changed, and returned again in altered form
The unit had structure, but not yet experience. For Kreegher, the work would have felt familiar in principle, but different in practice.
There were still stores to manage and vehicles to load, still the same underlying problem of keeping track of goods within a system, but here, nothing remained in place for long. Items moved constantly, forward, back, and forward again and already, one difference would have been clear. In civilian life, delays were inconvenient. Here, they mattered.
November 1941 – “Warning order received… prepare to move.”
Then came Operation Crusader, and with it, the moment the system was tested for the first time.
The OFP ceased to be a rear organisation and became part of the operation itself. It moved forward in sections alongside workshops, supporting brigades as they advanced and manoeuvred across the desert.
The idea behind it, holding the right spares and getting them forward quickly, was now being applied under real conditions and it began, slowly, to work.
Late November 1941 – “Short notice to move… one hour.”
The pace changed completely. There was no longer time to prepare once an order was given. Everything had to be ready in advance, loads pre-configured, vehicles maintained to a standard that assumed immediate movement.
Convoys formed quickly and moved out across the desert, often at short notice. Vehicles broke down, were recovered, repaired, and sent forward again. Stores were issued in response to unpredictable demand.
For Kreegher, the work shifted from structured to immediate; it was no longer enough to know what was held, he had to know where it was, how quickly it could move, and what mattered most when everything was urgent.
December 1941 – “Sea water entered camp… stores damaged.”
December brought both confirmation and cost.
By now, the OFP had been fully committed to operations, functioning as intended, organised with its headquarters and three sections, moving with the Division and supporting it under pressure. Like any unit of the Division, it was not immune to loss.
Major William Knox, the OFP Officer Commanding, had been injured after his vehicle struck a landmine during operations. Evacuated through Tobruk, he was lost at sea when the vessel carrying him was sunk. The loss does not appear in the daily rhythm of the diary, but it sits behind it, shaping the experience of those who remained.
At the same time, a storm flooded the camp. Stores were damaged, and work halted while everything was shifted to higher ground. It was a different kind of disruption, but just as real.
The system was exposed to everything and had to continue regardless; by the end of the month, the Division withdrew to Egypt. The OFP went with it, no longer untested but already altered by its first experience of war.
January 1942 – “Routine work.”
The new year begins with the same phrase, but it carries a different meaning now. Routine no longer suggests stability. It means the system is still functioning.
Day after day, the diary repeats it: “Routine work and maintenance of vehicles and stocks.” But underneath that repetition, the strain is visible.
Personnel are constantly moving in and out. Men are detached to workshops, others to salvage work, others to Cairo. Vehicles and drivers are sent forward. Others are loaned out to keep other parts of the system running. Even in “routine”, the unit is being pulled in multiple directions. There is also uncertainty, and it sits just below the surface.
Movement orders are issued, then questioned, then delayed. Advance parties are warned off, then stood down. Plans are made, then cancelled with little notice. At one point, the unit is preparing to move, lifting stores and coordinating transport, only to be told the move will not proceed: “Movement cancelled.”
That matters because movement is not just relocation; it is disruption. It means breaking down a functioning system and reassembling it somewhere else, often under pressure. By the end of the month, the movement will finally happen.
Sections begin to disperse. Transport is allocated to support infantry movement. One section moves forward to Mersa Matruh. The rest follow in stages, moving from Bagush through Amiriya and Mena, finally arriving at Fayid.
It is not a single move. It is a staggered, uncertain progression, shaped as much by changing orders as by intent and when they arrive, the final entry says it plainly: “Routine and camp duties. Erection of camp.”
Back to routine, but now in a different place.
February 1942 – “Routine, under pressure”
If January is uncertainty, February is pressure. The month opens exactly as the last one ended: “Routine work.” But almost immediately, the cracks show. There is a warning order to move to Tel el Kebir. A liaison is sent forward. Then the move is cancelled.
This pattern repeats. Orders are issued. Adjusted. Withdrawn. The system never quite settles.
At the same time, leadership and personnel are shifting. Command changes hands. Officers are sent forward or to Cairo. Sections operate semi-independently. The OFP is not acting as a single, stable entity; it is being stretched across tasks and locations, with the cost becoming;
“Pte. Condon killed in Matruh.” “Sgt. Moore killed – result of motor accident.”
These are not battle casualties in the traditional sense. They are the cost of movement, of vehicles, of long distances, of a system operating under constant strain. At the same time, the work does not slow. Trucks are moving constantly, to Tel el Kebir, to Abbassia, collecting parts, building up scales, trying to complete holdings. Engines are already appearing as a recurring requirement, being brought back in loads to keep vehicles operational.
Training begins to reassert itself. Courses are planned, cancelled, and then replaced with structured syllabi. Rifle practice is carried out. Maintenance and interior economy are scheduled. This is important, even in instability, the Division is trying to impose structure.
But by the end of the month, the underlying reality returns. A warning order of movement is received.
March 1942 – “Move ordered.”
When the Division moves to Syria, the system is stretched again, this time by distance rather than tempo.
The convoy north is long and deliberate, moving through Palestine and Lebanon into Syria. It is not a quick repositioning, but a sustained movement across a wide theatre, and in that movement, the OFP changes again.
Sections are attached to brigades and workshops, operating independently while remaining linked. The unit is no longer defined by location, but by the flow of stores and support across distance; it becomes, in effect, a network.
April 1942 – “Routine, across distance”
By April, the word “routine” is still there, but it no longer describes a single place. It describes a system spread across the Middle East with the month opening with what looks familiar: “Routine – settling in new area.”
But almost immediately, the scale becomes apparent. Trucks are moving not just locally, but across the theatre:
To Aleppo.
To Beirut.
To Haifa.
To Damascus.
This is not one OFP in one location. It is a network.
Sections are operating forward and rearward at the same time. “A” Section is forward at Aleppo. “C” Section moves through Damascus. Other elements are tied into Base Ordnance Depots and Advanced Depots, collecting, returning, redistributing. The system is no longer just moving. It is stretched, and at the centre of it, the same pressure point is emerging, more clearly now: Engines.
Requests go to ADOS. Trucks are sent to Advanced Ordnance Depots. Engines are collected, allocated, and sent forward again. There are moments where the scale becomes visible.
Eighteen Ford engines collected.
Fourteen engines issued forward to units.
Even then, it is not enough with a constant flow because the demand is constant. Around that, everything else continues. Oxygen and acetylene are being sourced from Beirut to support workshop output. Electrolyte is sought, but unavailable. Tyres require authorisation. “Quick moving parts” are identified and prioritised.

This is a system trying to define what matters most. At the same time, administration is catching up. Lists of dead stock are compiled for return to depots. Personnel rotate through “tours of duty” at Base Ordnance Depots. Sections report, detach, and re-form.
It is no longer just about issuing it is about controlling the flow, and then there is another layer: The routine orders. On paper, they look like administrative detail, but they tell you something about the environment the system is operating in.
A vehicle left unattended is stripped almost completely before it can be recovered, radiator, carburettor, wiring, even seats and glass.
Anti-malarial discipline is being enforced because units are not taking it seriously enough.
Even ice cream is banned, not as a comfort issue, but as a disease risk.
These are not side notes. They are reminders that the system is operating in an environment where:
equipment disappears if not secured,
disease is a constant threat,
and small failures quickly become bigger ones.
Through it all, the diary still returns to the same word: “Routine.”

But by April, that word has changed again. It no longer means the system is simply functioning. It means it is functioning across distance, under constraint, and with no single point of control.
May 1942 – “Trucks away to Haifa… Beirut… Aleppo.”
By mid-1942, that network is fully established. Vehicles move constantly between depots and forward elements. Engines circulate through repair and reissue. Stores move forward, are consumed or damaged, and then re-enter the system through recovery and repair. The distances are greater, the coordination more complex. And at the centre of it all is the same constraint: engines.
The Division’s mobility depends entirely on them. Without engines, vehicles stop. Without vehicles, movement stops. And without movement, operations stall.
Yet even amid this relentless tempo of war, there were brief moments where time could be found to step beyond the immediate demands of operations. In those intervals, however rare, it was possible to take in the history of the region, to observe the landscape not just as ground to be traversed or fought over, but as a place shaped by those who had come before. These moments did not diminish the intensity of the campaign but rather provided a quiet counterpoint, a reminder of the broader world beyond the machinery of war.

June 1942 – “Engines short.”
By June, the pressure is constant. There are never enough engines. Deliveries arrive slowly, demands increase, and the system is forced to adapt.
For Kreegher, this marks another shift. The work is no longer simply about handling stores. It becomes about judgment. Deciding what moves first, what can wait, and how to keep the system functioning when it cannot meet every demand.
July–November 1942 – El Alamein
The Division returns to the desert, first at Mersa Matruh and then at El Alamein. By now, the OFP is no longer learning how to operate. It is operating. What had been a system still forming in early 1942 is now functioning under pressure, and at scale. The diaries begin to read differently. Less about arrangements, more about execution.
In July, there had still been signs of friction, reorganisation, and uncertainty. Convoys arrived, loads were redistributed, and the question of how stores should flow through the system was still being worked out.
By August, that friction was being resolved. Vehicle holdings increased, bin trucks were introduced, and coordination with workshops, Base Ordnance Depots, and transport units became routine rather than negotiated.
By November, at El Alamein and during the advance that followed, the difference is clear.
The system holds. Stocks are described as good, sustained by the regular arrival of convoys from the rear. Sections move forward, split, and rejoin without disrupting output. Stores are received, broken down, and issued forward almost as soon as they arrive. The OFP is no longer tied to a place. It moves with the Division, and the tempo reflects that.
Orders to move come with little notice. Positions change frequently. The unit advances forward through Sidi Haneish, toward Sidi Barrani, and beyond, at times halted by enemy movement, traffic congestion, or uncertainty ahead, then moving again as soon as routes open. Even in those moments, the work does not stop. Convoys are met. Stores are offloaded. Loads are prepared for issue. Units arrive to collect what they need, and are turned around quickly. The system continues, even while in transit.
There are small details that reveal the scale of what is happening. Engines arrive and are issued immediately. Oxygen and acetylene are collected to sustain workshop output. Tyres, springs, and vehicle components move continuously through the system. Controlled stores are tracked, returned, and reissued.
Nothing sits still, and the volume is increasing.
By late November, the unit had recorded over 2,000 issues in two weeks, compared with a previous peak of 1,565 during operations in Syria. The demand is higher, the flow faster, and the consequences of delay more immediate. There is also strain.
Routes are blocked. Movement is delayed. Units stage overnight waiting for orders or clearance forward. At Halfaya Pass, traffic and congestion slow movement to a crawl before the unit pushes through and rejoins the advance. But the system adapts.
Loads are rearranged. Trucks are redirected. Sections move independently and then reform. Indents are pushed back through Corps channels, and stores continue to flow forward. It does not break, and for Kreegher, this is the point where the nature of the work settles into something constant. There is no longer a distinction between routine and operation. This is both.
The work is the same, checking, loading, issuing, accounting, but now it is done:
on the move,
at short notice,
and with no margin for delay.
By the time the fighting at El Alamein gives way to pursuit, the OFP has reached a point of quiet competence. It is no longer reacting to the war. It is keeping pace with it.
December 1942 – “Packed up… moved… issues only.”
After the advance from El Alamein, the movement does not stop. If anything, it becomes more complicated.
The Marble Arch (Arch of the Philaeni) and its adjacent airfield in Libya, which the New Zeland Division captured on December 1942
December is defined by constant displacement. The unit moves repeatedly, sometimes by day, sometimes at night, often covering significant distances before halting, only to move again shortly after. Convoys stretch out, break, reform, and push on. Breakdowns occur. Vehicles are taken in tow. Routes are blocked and reopened.
There is no fixed position. Even when halted, the work continues. The diary captures it in fragments:
“Moved 70 miles…” “20 miles night move…” “Broke down and stayed put…” “Issues only…”
That last line matters.
“Issues only” does not mean less work. It means the system has no time for anything else.
Stores are coming forward from 30 Corps. Trucks are being sent back to Benghazi and Corps depots. Engines arrive in small numbers and are immediately allocated. Tyres, springs, and general stores move through as quickly as they can be handled.
There is also a noticeable shift as stocks begin to build again. Late in the month, the diary notes engines arriving in quantity, Bedford engines, Chevrolet engines, stores accumulating to a point where the unit is no longer operating hand-to-mouth but beginning to regain depth, but that does not reduce the pressure. It changes it.
Now the problem is not simply receiving stores but controlling them, allocating them, and pushing them forward quickly enough to meet demand. By the end of December, the OFP is busy, continuously issuing, receiving, and already preparing for the next move.
January 1943 – Movement Without Pause
January opens the same way December ends. Movement orders. Convoys. Repositioning. The OFP shifts repeatedly as part of Administrative Groups, moving tens of miles at a time along the Divisional axis, often delayed, sometimes held up for an entire day, then pushed forward again.
The diary reflects a system in motion, but not always smoothly: “Very poor run… held up most of day… only 17 miles.” Distance is no longer the only problem.
Congestion, coordination, and timing now shape movement just as much as terrain. At the same time, the work continues.
Trucks move constantly between Corps depots, vehicle parks, and the unit. Engines are collected, returned, reallocated. Vehicles are issued forward and recovered back. Sections split across groups, then rejoin. There is also a growing administrative load.
Courts of inquiry. Conferences with ADOS. Reorganisation discussions. Selection of personnel for return to Base or continuation of service. The system is no longer just moving stores.
It is managing itself and running through it all, unchanged, and the same constraint is Engines. They are collected from Corps and returned when unserviceable. Reissued when available. Allocated carefully, often in small numbers, always with demand exceeding supply.
For Kreegher, this is where the work becomes sharper. It is no longer about keeping up. It is about making decisions inside a system that cannot satisfy every requirement.
February 1943 – Pressure Becomes Routine
By February, the character of the work changes again, no because the pressure lifts, but because it settles.
The diary becomes repetitive in a different way:
“Engines issued…”
“Engines received…”
“Allocated to units…”
“Routine…”
But that “routine” is deceptive.
Engines are still arriving from Corps and Advanced Ordnance Depots and are being issued forward immediately. Repairable engines are returned. Indents continue. Demand remains constant. What has changed is the system’s ability to absorb it.
The opening of 557 Advanced Ordnance Depot for issue marks a shift. Indents are now directed through a more structured channel. Stock flow becomes more predictable, even if still insufficient. At the same time, the scale remains high. Vehicles and guns are collected and redistributed. Infantry sections are busy. Engine issues for the month are recorded as high, and there is another subtle development.The system is being adjusted.
Conferences are held on establishments. Changes are made to include Reserve Vehicle Park (RVP) functions within the OFP structure. Roles are refined, not in response to a crisis, but in anticipation of what is next.
By now, the OFP is no longer reacting to the campaign. It is sustaining it, and for the men inside it, the work has settled into something constant, not easier, but understood.
24 February 1943 – Promoted Lance Corporal
The promotion reflects what has already happened. Kreegher is no longer new to the system. He understands it.
5 March 1943 – “Engine situation still acute… not good.”
The strain continues into 1943. Supply struggles to keep up, and the system remains under pressure, but it holds, and by now, Kreegher is part of the reason it holds, and by March, he is no longer simply receiving instructions; he is inside the machinery of it. At the corporal level, and moving toward greater responsibility, his world is not the broader strategy of the campaign, but the immediate, relentless problem of making the system function when it is short of everything that matters, and nothing matters more than engines.
The war diary records the problem in blunt, almost repetitive language: “Supply very slow… not up to figures expected.” “Engine situation still acute… not too good.”
For Kreegher, this is not an abstract shortage. It is practical, daily friction, it is vehicles waiting in lines that cannot be issued forward. It is workshops demanding engines that have not arrived.It is checking manifests against reality and finding gaps that cannot be closed. It is loading trucks with what is available, knowing it is not enough.His work sits at the point where paper meets reality. Indents say one thing, stock on hand says another, and it is the NCOs who reconcile the difference.
Day after day, that means:
organising collection parties,
supervising loading and unloading,
tracking controlled stores,
and reallocating what little is available to the units that need it most.
There is no single moment of decision; there is only constant adjustment, and when engines do arrive, the pressure does not ease. It shifts.
“Received 40 engines, all allocated.”
For Kreegher, that means the work accelerates.
Forty engines do not sit in a yard.
They are immediately broken down into tasks:
identifying allocations,
matching engines to vehicle types,
organising transport forward,
and ensuring that nothing is lost, miscounted, or misdirected in the process.
Mistakes here do not stay local. An incorrectly issued engine can immobilise a unit miles ahead. So the work is careful, even when it is rushed. Especially when it is rushed. At the same time, the unit is moving, and movement multiplies the difficulty. Convoys form at short notice. Orders change. Sections are split and recombined. Some elements move forward while others remain back to rebuild stocks.
For Kreegher, that means doing the same work, but now:
in transit,
in new locations,
often in the dark,
and with incomplete information.
The diary notes: “Very slow moving… everything came through satisfactorily.”
That “satisfactorily” is earned, it reflects the work of men like him, ensuring that stores are accounted for, loads are secured, and nothing critical is left behind in a system that is constantly on the move. There is no space for failure. Only for recovery.
April 1943 – “Working at scale”
By April 1943, the word “routine” still appears, but now, it means something very different. The OFP is no longer struggling to function, it is working, and working at scale. The month opens with movement, but it is controlled movement.
The unit shifts with Workshops to a new location near Divisional Headquarters, immediately issuing engines and dispatching loaded trucks forward. There is no pause.
Engines arrive, are allocated, and disappear into the system almost as quickly as they come in.
Trucks are sent back to Tripoli for stores. Others return from Corps units loaded with engines, vehicles, and controlled stores. The flow is constant, and now, it is organised.
Even when the unit is not advancing, it is not static. Orders to move come, are acted on, and executed with little disruption.
The OFP packs, moves, and re-establishes itself as part of a larger formation movement, covering significant distances in a single day: “Moved at 0700 hrs… run for day 85 miles.” Then again:
Night moves.
Short bounds.
Repeated relocations along the Divisional axis.
But unlike 1942, the movement does not break the system; it is part of it. Stores continue to arrive from Tripoli. Engines continue to be collected from 10 Corps. Trucks continue to be loaded, unloaded, and turned around. The system moves and continues to function while moving. By now, the central constraint is unmistakable. Everything revolves around engines. They are:
Collected from 10 Corps depots
Returned when unserviceable
Allocated centrally through ADOS
Distributed immediately to units
At one point, the scale becomes explicit: “Total of 40 engines allocated and distribution made out.”
That is not incidental. That is the system operating at volume and yet, even here, supply is uneven. On some days engines arrive in quantity and are issued out immediately. On others: “No engines received.” The flow is constant but never assured.
What sets April 1943 apart is not just activity but control. The system is now managing itself.
Controlled stores are tracked and redistributed
Vehicles are collected from Corps parks and issued forward
Dead stock is identified and returned
Personnel are reassigned between sections to meet demand
Census of controlled stores is conducted under ADOS direction
Even the structure is being adjusted. Sections are reorganised. Personnel move between Reserve Vehicle Platoon (RVP), Holding, and operational sections. Additional tradesmen are brought in from NZEME. This is no longer a system reacting, it is a system refining itself.
By the end of the month, the scale of output is clear. Issues are running at: “approximately 200 per day.” That is sustained throughput. Not a surge. Not a peak. Routine.
Stocks are building gradually. Supply lines from Tripoli are functioning. Vehicles, carriers, and equipment are being pushed forward continuously, but the system is not yet comfortable. Tyres remain low, engines remain the constraint, future movement is still uncertain: “Unit still static with no information re moving.”
Even at this stage, there is no sense of permanence.
May 1943 – “Issues easing off as unit stocks improve.”
After Tunisia, the pressure begins to ease. Stocks improve, and the flow of stores becomes more predictable. For the first time in months, the system feels as though it is catching up with itself and for Kreegher, that changes the nature of the work.
The tempo drops, but the responsibility does not if anything, it becomes more visible.
The diary clearly reflects the shift: “Issues easing off as unit stocks improve.” “Things very quiet generally… issues slackening off.”
Where March had been defined by shortage and urgency, May is defined by consolidation.
But consolidation is not passive, it is detailed work.
For Kreegher, this is where his pre-war skills begin to reassert themselves more clearly.
Stocktaking
Sorting
Balancing holdings
Ensuring that what is on hand matches what is recorded
After months of operating at the edge of capacity, the system now has space to correct itself and that work falls heavily on NCOs. Stores are no longer just issued as they arrive. They are:
counted
inspected
repacked
and redistributed
Captured equipment is processed and handed over. Vehicles are returned, repaired, or reallocated. Summer clothing is issued, requiring organisation, sizing, and controlled distribution across units. None of it is dramatic but all of it is necessary.
The unit is described as “generally quiet,” transport “mainly static,” but that quiet reflects control, not inactivity, it means that work is being done properly, deliberately, with time to get it right and beyond the immediate tasks, there is a growing awareness of transition.
“North African campaign over. Warning order to move…”
For Kreegher, this is another shift from sustaining a campaign to closing it down. Stores are sorted for return.Salvage is processed. Loads are reconfigured for movement back to Egypt.
The same skills apply, but the purpose is different. Taken together, these months mark a turning point in his war. In March, he is working inside a system under strain, learning to operate under pressure, making decisions in the moment, and keeping things moving with limited resources.
By May, he is part of a system regaining control, applying discipline, restoring balance, and preparing for what comes next. The work has not become easier, It has become clearer and that is the quiet transformation not from chaos to order, but from survival to control.
And Kreegher is now firmly in the middle of it.
June 1943 – “Setting things straight”
By June, the movement has stopped not completely, but enough that something else can begin. The unit comes through from Amiriya and settles into a new position. Vehicles are in. Camp is established. Tents go up. For the first time in months, there is time to lay things out properly.
The diary captures it in a tone that feels almost unfamiliar: “Great day’s work… moved camp site and all tents erected.” That line says more than it appears to, this is not a convoy halt, this is a position, and with that comes a different kind of work.
Personnel changes begin immediately. Men move out to Base Ordnance Depot under exchange schemes. Others arrive. Leave programmes are worked through. Promotions are processed. The unit is being reset, not just physically, but administratively. There is also an effort to impose order.
Parades are held. Equipment is checked. Camp is “generally straightened out.” The language is telling and after months of movement, the priority is no longer speed, it is control. But even in this quieter phase, the underlying pressure does not disappear.
Stores are still being sorted. Tyres are still being accounted for. Issues may be fewer, but demand remains, and running through it, unchanged: Engines. The diary notes discussions with ADOS on engine requirements, anticipated collections, and ongoing shortages. By mid-month, the unit finally comes back together.
The Armoured Section rejoins from 4 NZ Armoured Brigade. For the first time since its formation in 1941, the OFP is concentrated in one place. That matters because it allows the system to function as a whole again. From there, the tempo begins to build, but in a different way.
Trips are made to Base Ordnance Depots, particularly Tel el Kebir, to collect engines, Ford engines, Bedford engines, whatever can be obtained. Trucks go out loaded with demands and return loaded with what can be secured. By the end of the month, a pattern is clear: “Trucks from Tel el Kebir with engines… issuing… stocks building up.” It is not abundance, but it is enough to start building depth. June is not a pause. It is a reset.
July 1943 – Work Resumes, Properly
If June is about getting ready, July is about getting back to work. The diary opens simply: “Collecting engines and stores from Tel el Kebir.” That is the month in a sentence.
Men return from leave. The unit is again at full strength, and the tone shifts immediately. There is no more settling in. The system is expected to function. Stores are now flowing steadily. Engines continue to arrive, still insufficient, still in demand. Requests go back to ADOS for more. Every arrival is allocated. Every allocation leaves a gap somewhere else but the key difference from earlier in the campaign is this: The system is no longer improvised it is organised.
Sections are issuing regularly. The Infantry Section takes over responsibility for issuing to divisional units. Workshops are engaged, welding, fitting, repairing. Vehicles are inspected, recovered, and redistributed. There is structure to the work now. There is also discipline.
Lectures are given. Parades held. Training introduced, even night exercises. Inspections take place. Conferences with ADOS shape how the system will operate going forward and still, through it all, the same constraint remains: Engines, tyres, springs. Collected from Tel el Kebir. From Abbassia. From wherever they can be obtained. Loaded onto trucks, brought forward, issued out.
Even the quieter entries reinforce it: “Routine only” by now, that phrase carries weight.
Routine means engines are still being chased.
Routine means vehicles are still short.
Routine means the system is still under pressure.
But it also means something else iIt means the system is working.
7 August 1943 – Promoted Corporal
The promotions come quickly now. They reflect both experience and necessity. The system is expanding, and it needs people who understand how it works.
August 1943 is not a dramatic month in the way the desert fighting had been, but it is no less important. The Division is no longer fighting for survival, it is reorganising for what comes next, and the OFP is right at the centre of that process. At first glance, the war diary reads almost casually: “Unit picnic at Barrage… skeleton staff left to picquet the lines.” There is rifle drill in the afternoons, inspections arranged, cricket matches played against rear units. It would be easy to read it as a period of rest, it isn’t.
Beneath that surface, the system is being adjusted, tightened, and reworked. Indents are reviewed, delivery systems questioned, and priorities argued through with Base Ordnance and ADOS. There is a constant thread of meetings, discussions, and quiet friction, not about whether stores exist, but about how fast they can move, and who gets them first. By mid-month, that work sharpens.
Conferences are held on the reorganisation of the OFP itself, including proposals to operate its own forward distribution, a recognition that the existing system is not fast enough for what lies ahead. Vehicles and personnel are reviewed, redistributed, and re-tasked.
“Conference… re-organisation of Ord. Fd. Pk… for more efficient service to Units.”
This is the moment when the OFP begins to shift from a supporting unit to something closer to a forward logistics node, integrated into the Division’s tempo rather than trailing behind it and running through it all is one very specific problem: engines.
Day after day, the diary returns to them. Chevrolet engines, Ford engines, Albion engines, controlled stores tied to them, allocations, collections, deliveries. Officers moving between depots, chasing availability, arguing allocations, arranging transport. “Collected engines and delivered as allocated… system now working.”
It is not just a supply issue.It is a readiness issue. Vehicles are the Division’s mobility, and mobility is its survival. Keeping engines flowing forward is not background work; it is an operational necessity.
By the end of August, the system is beginning to settle into a pattern. Stores’ positions are described as “good”, arrangements are in place, and the engine recovery and distribution system is functioning with some consistency. At the same time, there are clear signs of what is coming next.
Discussions about reinforcements, promotions, and the movement of sections begin to appear more frequently. The unit is not just sustaining the Division; it is preparing to move with it.
1 September 1943 – Promoted Sergeant
September 1943 brings that shift into focus as the tone changes immediately: “Stores coming through and issues heavy.” There is no longer any pretence of a lull. Volume increases, and with it, pressure. Engines continue to arrive from Base Ordnance Depots, now in larger numbers. Tank scaling for Sherman units is being issued. Ford scout car components, tyres, and controlled stores all begin to move through the system in parallel.
The problem is no longer a shortage alone. It is capacity. There is simply more to handle than the system was originally designed for. Even the diary notes it indirectly: “Impossible to carry same with present transport.”
Scaling, entitlement, and physical lift are misaligned. The system is being stretched, and adjustments have to be made in real time. At the same time, personnel turnover increases. Reinforcements arrive, postings change, and conferences focus as much on people as on stores. This is where Kreegher’s promotion to Sergeant on 1 September sits. It is not ceremonial, it is functional. The system needs NCOs who can run sections, interpret orders, manage priorities, and make decisions without waiting for direction. The flow of stores is now complex and continuous, and relies on the experienced men.
Mid-month, movement begins. Orders are issued. Sections are prepared to deploy. Vehicles are loaded, stores consolidated, accommodation equipment handed in, and the unit begins to break down its static footprint.
“Issued movement order… Armd Section packing up prior to move.” The move to Burg el Arab is deliberate, controlled, and tightly planned. Convoys are timed, routes specified, halts limited, spacing enforced. This is not just a relocation, it is a rehearsal. The OFP is learning to move as part of a larger operational system, not just as a unit changing camps.
Once in position, the work resumes immediately. The recovery and delivery sections are busy collecting and issuing vehicles. Controlled stores are distributed as units arrive. Base vehicles are received, processed, and pushed forward. The language of the diary becomes familiar again: issues, allocations, conferences, inspections. But the context has changed. By late September, there is a noticeable shift in tone: “Issues still high, although easing off slightly.”
The surge is stabilising, and stocks are building. Plans for the future begin to appear more frequently in discussions. Swimming parties start. Inoculations are carried out. Conferences are held to discuss what comes next, not just what is happening now. The system is no longer reacting, it is preparing. For Kreegher, this is the period where everything comes together.
By August, he understands the system, by September, he is helping run it. His promotions reflect that, but more importantly, they are a recognition that the war, at this stage, is being sustained not just by supply, but by organisation, adaptation, and control. The desert had demanded endurance. Italy would demand precision.
And the OFP is quietly reshaping itself to meet that demand.
October 1943 – “The system unwinds”
For Kreegher, October begins as it has for months: “Routine. Issues still heavy.”
Engines are still being issued. Stores are still moving. Vehicles still going back and forward to Base Ordnance Depots.
On the surface, it is familiar work, the same tasks, the same rhythm, but he would have recognised what was happening underneath.
The system was no longer building forward. It was being cleared.
Stocks pushed through.
Stores tidied and accounted for.
Supply lines are beginning to close down.
For someone who had spent the past year learning how to keep that system moving, this is something different, not sustainment, closure. Then the scale shifts: “27 truck loads of stores arrived…”
Kreegher is now part of the effort to concentrate what remains.
Sorting
Loading
Clearing
Not building a system, but dismantling it in an orderly way. Then, abruptly, the break.
Transit camps
Embarkation
Sailing
“Embarked… Sailed… At sea…”
For the first time since arriving in theatre, the work disappears. No engines to issue, no stores to account for, Just waiting, boat drill and routine at sea. A pause, but not a rest. More the absence of something that has become constant. Then: “Arrived TARANTO.” And whatever comes next, he will have to learn it again.
November 1943 – “Starting again, but not from nothing”
November does not begin with pressure, it begins with something quieter: “Routine. Foot drill. Rifle exercises.” For Kreegher, this is a shift. After months of continuous operational work, he is back on parade, back in training cycles, back in something that looks like structure. But it is not a return to the beginning. It is preparation. Movement returns, but it feels different now. More deliberate and less uncertain.
Advance elements move
The rest follow
Arrival near San Severo
Kreegher moves with the unit, but there is nothing familiar waiting for them. No established base system and no known flow of supply, just ground,l so the work begins again.
Kreegher is now part of a system that no longer sits in one place. It is spread out, attached, moving in parts rather than as a whole. That changes how the work feels.It is less central., more immediate and more dependent on what is happening around him, and almost immediately, the pressure returns.
“Innumerable enquiries for stores.” Units are asking, and the system is not ready. Kreegher is no longer just processing stores. He is part of a system that is trying to catch up. By the end of the month, it begins to take shape. Not stable, but functioning.
He knows the work now, but the system around him is still settling.
December 1943 – “Learning a different kind of difficulty”
By December, the work is fully back, but it feels different.Movement is no longer just movement it is difficult.
Rain turns roads into mud.
Vehicles struggle to get through.
Recovery becomes constant.
The Diary notes “Road in was in a bad state… recovery indispensable.” For Kreegher, this changes the day, what was once routine movement now takes time, effort, and coordination. Nothing is simple.
Supply tightens and Depots restrict what can be drawn with only priority demands are met with “Only VOR indents getting any action.” He is still issuing and still accounting, but now, not everything can be satisfied. Distance changes the work. “Trip to Foggia takes practically three days.”
For Kreegher, that means delay and what is needed now will not arrive today or tomorrow. The system is no longer immediate and stocks become uneven, some things arrive, some do not. Engines still dominate demand, fast-moving parts remain short.
The work becomes more deliberate with more decisions and more prioritisation, so the system adapts, and Kreegher adapts with it.
Unserviceable engines gathered at road junctions
Recovery vehicles kept in constant use
Trucks sent out for days to find what is needed
This is not the system he learned in North Africa, but the work is still recognisable and the scope widens.
Weapons
Ammunition
Blankets
Stretchers
Mule equipment
For Kreegher, the realisation is quiet but important, this is not just about vehicles, it never was. By the end of December, something settles. Not easy to understand; he knows the work, he understands the system, but the system itself has changed and is slower, more fragile, and more dependent on everything around it. By the end of 1943, Kreegher had learned how the system worked. What he was now learning was how easily it could be made to struggle.
January 1944 – “Heavy snow… roads impassable.”
The year does not begin with movement, it begins with weather, with the diary noting “Heavy fall of snow… tried to make the main road, but failed.” For Kreegher, this is something new. In the desert, distance had been the problem here, it is access. The system cannot move because the ground will not allow it.So it adapts.
A dump is established near the main road
Stores are offloaded and sorted forward
Loads are broken down where they can be reached, not where they were intended to go
Kreegher is no longer working in a flowing system, he is working in fragments as conditions worsen.
Mud
Snow
Sleet
“Sorting continues in the rain and sleet… a very sorry spectacle for valuable stores.” This is not inefficiency, it is a necessity.By the end of the month, the pattern is clear.
Forward dumps
Controlled movement
Short-haul distribution
The system is no longer pushing forward. It is feeding forward.
29 January 1944 – Promoted to Staff Sergeant
The promotion reflects more than experience.Kreegher has moved with the system through every stage:
From formation
to function
to maturity
Now, he is part of how it is controlled.
February 1944 – “Arranging supply… not sufficient”
February brings structure, but not relief. Trips to Naples, Salerno, and forward depots become routine. Contacts are established, and supply chains begin to take shape. For Kreegher, the system is becoming visible again. Not as movement, but as a network. But the limits are already clear.“Monthly allocation… will not suffice.” Supply exists but not in the quantities required. The work becomes one of arrangement with less physical effort and more coordination. Movement continues, but in smaller bounds.
Short displacements
Advance parties
Rear parties left behind
The system is no longer continuous. It is staged. For Kreegher, this changes the work. Not just issuing, but deciding what can be issued.
March 1944 – “Area cutting up badly… all transport in and out.”
By March, the problem is no longer a shortage; it is congestion with too many vehicles and too little ground. The diary noting : “AOD area cutting up badly… all transport coming in and out.” Kreegher is now working inside a system at capacity. Transport is not lacking.It is competing. Bulk breaking becomes constant. Stores arriving from multiple depots. Sorted, divided, and pushed forward again. The system is functioning. But only because everything is being managed closely and the structure continues to evolve.
Vehicles are split between Armoured and Infantry OFP Sections with new establishments adopted and roles refined. This is no longer an adaptation. It is optimisation under pressure.
April 1944 – “Engines going out slowly…”
April brings a different problem, not congestion but flow: “Engines going out slowly… ahead of arriving stores.” Demand is ahead of supply. For Kreegher, this means working with imbalance. Issuing what is available and managing what is not. Large quantities begin to move again.
Tyres in bulk
Major assemblies
RVP vehicles supporting distribution
The system has depth again, but not consistency. Movement resumes in a more deliberate form.
Packing
Loading
Relocation across rivers and choke points
This is controlled mobility and still, the same underlying constraint:
Manpower
Time
Flow
May 1944 – “Engine releases to hand…”
By May, the system begins to ease.Engine releases arrive and stocks begin to clear. For the first time in months, Kreegher is working with supply that is catching up. But the work does not slow.
Monthly returns
Policy discussions
Coordination with Corps and Brigade Ordnance elements
The system is now administrative as much as physical. New relationships form as South African Ordnance elements arrive with shared arrangements are agreed. The system is no longer purely New Zealand. It is part of a wider structure.
Shortages remain: “Oxygen in short supply.” Even as some constraints ease, others emerge. For Kreegher, the work is now balanced between:
Issuing
coordinating
and managing expectations
June 1944 – “Hostile shelling… vehicles dispersed.”
By June, the system moves forward again and with it, Kreegher. Movement to forward areas is rapid.
Convoys in
Stores offloaded
Sections pushed forward
But now, there is something new.Threat. “Hostile shelling… vehicles dispersed… camouflage precautions taken.”
The OFP is no longer behind the war It is inside it. This changes everything. Vehicles cannot concentrate, stores cannot be held in one place, movement must be controlled and concealed. At the same time, demand increases. The system is under pressure from both sides: Enemy action and operational demand.
For Kreegher, this is the most complex phase yet: movement, supply, and threat all at once.
July 1944 – “Move commenced 0200 hrs… 105 miles.”
By July, the system moves again, north. Convoys form and night movement begins with long distances covered. Kreegher is back in motion, but this is not the desert, movement now includes:
Forward supply
Rearward recovery
Return of stores
Redistribution of equipment
August 1944 – “Engines allocated and delivered… trucks to roadhead.”
The system is no longer one-directional; it is circular. The system is repositioning itself, but even in this, the work continues, Stores arriving from Naples. from Bari, from railheads. The flow never stops for Kreegher, this is now familiar, movement, pause, reorganisation, continuation. By mid-1944, Kreegher was no longer adapting to the system, he was part of how it adapted to everything placed against it.
By late 1944, the system was operating at full tempo. Engines were being allocated, issued, and moved forward continuously. Trucks ran to roadheads, often returning partially loaded, sometimes empty, but always moving. The work was constant, defined less by individual tasks than by the flow itself.
Even routine entries reveal the scale of effort, vehicles cycling through, stores arriving unevenly, and controlled items being tracked carefully across multiple nodes.
September 1944 – “Thirty-six trucks in… tyres and stores… issues slow.”
Volume became the defining challenge. Large numbers of vehicles arrived with stores, but distribution struggled to keep pace. Issues slowed, not due to shortage, but due to the difficulty of handling and moving what was already available.
Movement orders came and went, sections repositioned, and the system adjusted again.
October 1944 – “Heavy issues… winter clothing… vehicles delayed.”
Seasonal change brought its own demands. Winter clothing and equipment were issued in bulk, adding pressure to an already stretched system. Vehicles struggled to reach forward areas due to terrain and congestion, and the simple act of getting stores into position became increasingly difficult. Even so, the system held.
November 1944 – “Quiet day… stores loaded… vehicles returning.”
By November, a different rhythm begins to emerge. There are still movements, still issues, still recoveries, but the intensity begins to ease. More vehicles return than depart. Backloading increases. Controlled stores are redistributed rather than urgently demanded. It is not a pause.But it is a shift.
December 1944 – “Stores slow… little activity… conference on organisation.”
By December, the tempo drops noticeably. Stores arrive more slowly. Issues are lighter. Conferences begin to focus on organisation rather than immediate demand. Sections are reviewed, roles adjusted, and the structure refined. The system is no longer reacting. It is stabilising.
January 1945 – “Stores becoming available… sections quiet… snow heavy.”
The new year begins quietly. There is work, but it lacks the urgency of earlier periods. Stores are now available in greater quantity, and the system shifts from managing shortage to managing distribution and storage. Snow and weather restrict movement, reinforcing a slower tempo.
Conferences with senior ordnance officers become more frequent, focusing on policy, organisation, and future structure rather than immediate operational demands.
February 1945 – “Reorganisation going to plan… issues low… quiet day.”
By February, the change is clear. Reorganisation is underway. Sections are adjusted. Personnel are reviewed. Reinforcements arrive, though not always to immediate effect.
Issues are low. Activity is steady but subdued. The system is no longer under strain. It is being reshaped.
March 1945 – “Salvage still rolling… sections packing to move… general quiet.”
March brings a sense of transition. Salvage operations continue, clearing equipment, recovering stores, and closing out areas. Sections are being prepared to move, packing, reorganising, and shifting locations. There is still work, but it is different work.
Less forward movement, more consolidation, more preparation for what comes next. The diary speaks of routine, but it is a quieter routine now, punctuated by conferences, inspections, and the gradual winding down of activity.
March–May 1945 – “Returned, but not yet finished”
Kreegher left the theatre before the war formally ended. He returned to New Zealand aboard the Tongariro, departing in late March 1945 and disembarking at Wellington on 21 April.
But the return did not mark an immediate end to his service. He was not released on arrival. Instead, he remained under military care, undergoing rehabilitation and minor surgery for a hernia, a condition he had been unaware of during his time overseas.
Like much of his war, it passed without comment. There was no clear moment that marked the transition from soldier to civilian.
October 1945 – Discharge
His final discharge came in October 1945. By then, the war had ended, and the system he had spent four years inside had begun to unwind. The urgency, the movement, the constant demand, all of it was gone.
He returned to Northland. To the same world he had left in 1940.
In December 1949, he married Enid Jean Chatfield in Remuera, Auckland. Together, they began building a life that, on the surface, reflected the same order and structure that had defined his pre-war years.
Fred Kreegher died at his home in Mount Albert, Auckland, on 26 May 1956. He was forty-four.
Closing Reflection
Like many men of his generation, he did not speak much about the war. There are no detailed personal accounts, no reflections in his own words that explain what those years meant. What remains are fragments:
A few photographs
A handful of names
A sequence of places
He was not a prominent figure. He did not command units or shape strategy. But he was part of something larger. He was one of the men who kept the system working. One of the clerks, storemen, NCOs, and technicians who ensured that vehicles moved, that weapons functioned, and that the Division could continue to fight.
Work that rarely appears in history. But without which the war could not have been sustained. He left behind little in the way of personal record. But the system he served in, and helped keep moving, leaves a clear trace. And through it, his war can still be understood.
The period from 1946 to 1948 represents one of the least understood, yet most consequential phases in the history of the Royal New Zealand Army Ordnance Corps (RNZAOC), not because of what it achieved, but because of what it resolved.
What emerged was not a finished system, but an Army still taking shape. The post-war force was, in effect, an interim army, suspended between wartime structures and peacetime requirements, retaining elements of one while attempting to define the other.
Demobilisation had been rapid, but the future force remained undefined. Establishments were provisional, organisations were in flux, and there was no settled view of scale or role. For the RNZAOC, this meant operating a logistics system built for global war within a smaller, resource-constrained environment increasingly focused on efficiency and control.
At the same time, responsibility between corps and units remained unsettled. Wartime practice had pushed holdings and authority forward to units; post-war thinking sought to reassert centralised control. The balance between the two was neither clear nor stable, resulting in ongoing adjustment across supply, accounting, and distribution.
The outcome was a system in transition. Depot structures were reorganised, trade roles adapted, and establishments repeatedly revised, all reflecting deeper, unresolved questions about control, capability, and scale.
This article examines how the RNZAOC navigated this interim phase through organisation, depots, trades, and the evolving relationship between corps and unit responsibility, a period in which the foundations of the post-war Army were not inherited but worked out in practice.
Pre-war Decline and Wartime Rebuilding
Before the Second World War, the NZAOC had been significantly hollowed out. The economic pressures of the interwar period, particularly the effects of the Depression, saw the Corps reduced to a minimal military presence. Much of its traditional supply function was civilianised, with depot operations, accounting, and store management largely undertaken by civil staff. Uniformed personnel were limited to officers and a small number of technical specialists.[1]
This reflected a prevailing belief that large-scale military logistics systems were unnecessary in peacetime. The outbreak of war in 1939 completely overturned this assumption.
The demands of mobilisation, overseas deployment, and sustained operations required the rapid expansion of a military-controlled logistics system. The RNZAOC was rebuilt into a large, uniformed organisation responsible for supporting both expeditionary forces and home defence. Depots expanded, new facilities were established, and personnel increased significantly.[2]
By 1945, the Corps had regained both scale and operational relevance. The wartime experience demonstrated that military-controlled supply was essential, and there was little appetite to return to the pre-war model. The RNZAOC was not rebuilding from scratch; it was preserving the relevance it had regained during the war.

From Wartime Expansion to Peacetime Reality
The transition to peace introduced a different set of challenges. The wartime logistics system was too large to sustain, yet too valuable to dismantle. The Army, therefore, faced a balancing act, reducing size while attempting to retain capability.
This was neither a clean nor a coordinated reform. It was a gradual process of adjustment in which wartime structures were reshaped rather than replaced.
New Zealand’s continued overseas commitments, including the occupation of Japan, ensured that ordnance services remained operationally relevant even in peacetime.[3] The system was therefore neither fully wartime nor fully peacetime, but something in between.

The Impact of RNZEME Formation
A major structural change occurred on 1 September 1946 with the formation of the New Zealand Electrical and Mechanical Engineers (NZEME).[4] This brought together mechanical transport, ordnance workshops, and technical repair functions under a single corps.
For the NZAOC, this marked a significant shift. Repair and maintenance functions began moving out of the Corps, but the transition was incomplete. Equipment, personnel, and responsibilities remained interdependent.
1946 establishment proposals note that Mechanical Transport holding units were under NZEME control, with the expectation of later transfer to Ordnance.[5] This highlights the reality that the separation between supply and repair was still evolving.
Reorganisation of the Ordnance System
At the same time, the RNZAOC underwent internal reorganisation. Wartime expansion had created parallel structures, which now required integration.
Regular and non-Regular personnel were brought together into a single Corps, and control of ordnance services was centralised under Army Headquarters.[6] The resulting structure included Headquarters New Zealand Ordnance Services, an Inspecting Ordnance Officer Group, the Main Ordnance Depot at Trentham, and a system of district sub-depots and ammunition sections.[7]
This represented a shift toward a more coordinated national system, although the reality remained more fluid than the structure suggested.
Identity and Recognition: Becoming “Royal”
In 1947, the Corps was granted the prefix “Royal,” becoming the RNZAOC.[8] This recognised its wartime service and reinforced its position within the Army. At a time of organisational change, this provided continuity and strengthened the Corps’ identity.

Depots, Distribution, and Control
The depot system remained the foundation of RNZAOC operations in the immediate post-war period, providing the physical and administrative framework through which the Army was sustained. However, this system did not operate in isolation. Rather, it formed part of a broader ordnance structure directed from Headquarters, New Zealand Ordnance Services, under the Director of Army Equipment. This was not simply a continuation of wartime arrangements, but a deliberate reorganisation into a coordinated national system designed to balance centralised control, technical oversight, and regional responsiveness. Within this framework, two principal functional groupings can be identified:
Main Ordnance Depot (MOD), Trentham. The Main Ordnance Depot (MOD) at Trentham formed the core of the national supply system. It held the Army’s primary reserve of ordnance stores, managed procurement and stock control policy, and acted as the principal interface with Army Headquarters. The MOD was responsible for bulk storage, cataloguing, and redistribution of stores to subordinate elements. It also retained accounting authority for much of the Army’s inventory, ensuring that financial and materiel control remained centralised even as physical distribution was decentralised.
Inspecting Ordnance Officer (IOO) Group. Alongside the supply system, the IOO Group provided technical oversight across the entire ordnance structure. Incorporating ammunition inspection and repair functions, it maintained a presence both centrally and within each military district, linking local activity to central technical authority. Its responsibilities included the inspection of ammunition, enforcement of technical standards, and assurance of safety and serviceability. This arrangement highlights that RNZAOC’s role extended beyond supply to include technical control, particularly in relation to ammunition condition and safety.
District-Controlled Supply and Ammunition System
Beneath this national framework, the system was implemented through district-controlled elements, in which general supply and ammunition were managed in parallel rather than as a single unified chain.
Sub-Depots (General Supply)
The sub-depots formed the primary regional distribution layer for general stores:
No. 1 Sub-Depot (Hopuhopu, Northern District) supported formations and units in the Auckland and Northern military districts. It received stores from Trentham, maintained regional holdings, and issued equipment to units, ensuring responsiveness to both routine requirements and operational contingencies.
No. 2 Sub-Depot (Linton, Central District, including Waiouru) occupied a particularly significant role, supporting the Army’s principal training area. Its responsibilities extended beyond routine supply to include provisioning for major exercises, maintenance of field stocks, and the rapid issue and recovery of equipment.
No. 3 Sub-Depot (Burnham, Southern District) supported forces across the lower North Island and South Island. Its role was shaped by distance and dispersion, requiring an emphasis on distribution efficiency and continuity of supply to smaller, geographically separated units.
District Ammunition Sections
Operating alongside, but not subordinate to, the sub-depots were the District Ammunition Sections. These existed as a distinct and tightly controlled system under district authority, reflecting the specialised and hazardous nature of ammunition management.
Each District Ammunition Section was responsible for:
the storage and accounting of ammunition stocks
inspection and maintenance in accordance with technical standards
issue to units and recovery of ammunition
enforcement of safety regulations and handling procedures
This arrangement reflects the fundamentally different nature of ammunition within the logistics system. Unlike general stores, ammunition required specialised handling, stricter accounting, and continuous technical oversight. As a result, it was managed through a parallel structure, linked to but not absorbed within the general depot network.
Together, these elements formed a layered and functionally divided national system. General stores flowed from central procurement and bulk storage at Trentham through the sub-depots to units. Ammunition followed a parallel pathway through District Ammunition Sections, governed by tighter technical and safety controls. Oversight, inspection, and policy direction remained centralised through Headquarters and the Inspecting Ordnance Officer.
Just as importantly, information flowed in the opposite direction. Demands, returns, inspection reports, and accounting data fed back into the central system, ensuring visibility and control across both supply and ammunition functions.
This structure reflects a conscious attempt to balance three competing imperatives:
Centralised authority, ensuring control over procurement, accounting, and technical standards
Technical assurance, maintaining oversight of equipment condition and ammunition safety
Regional responsiveness, allowing units to be supported quickly and efficiently
What emerged was neither a purely wartime expeditionary system nor a fully developed peacetime bureaucracy, but a hybrid. It retained the scale, discipline, and functional separation developed during the war while adapting to the realities of a smaller, permanent force.
In doing so, the RNZAOC avoided a return to the fragmented, partially civilianised structures of the pre-war period. Instead, it established a controlled, professional, and distinctly military system of national sustainment, one capable of supporting both routine operations and future mobilisation. This dual structure of centralised control, regional distribution, and parallel ammunition management did not disappear with post-war reform but remained a defining feature of New Zealand Army logistics as it evolved through the later twentieth century into the integrated systems of the RNZALR.
Personnel, Trades, and Overlapping Responsibility
The RNZAOC of the immediate post-war period was defined less by a clean, corps-based trade structure and more by a functional mix of personnel drawn from across the Army. Within ordnance units and depots, storemen, clerks, ammunition specialists, technical tradesmen, and general labour staff often worked alongside or in parallel with personnel from other corps.[9]
This reflected the legacy of wartime expansion, in which capability had been built rapidly and pragmatically rather than along strictly defined corps boundaries.
In formal terms, RNZAOC responsibilities centred on a recognisable, though not exclusive, group of trades. Based on Army Order 60 of 1947, these included:
Storeman (general and technical)
Clerk (including specialist and accounting clerks)
Ammunition Examiner
Munition Examiner (WAAC)
Tailor
Shoemaker (Class I)
Clothing Repairer / Textile Re-fitter
Saddler and Harness Maker
Barrack and general support roles (e.g. barrack orderly, store labour staff)
These trades broadly reflect the traditional functions of the Corps, supply, storage, accounting, inspection, and the maintenance of clothing and general equipment. However, this list reflects RNZAOC-associated trades rather than RNZAOC-exclusive trades.
In practice, roles such as storeman and clerk were distributed across multiple corps and at unit level, often performing similar functions under different organisational control.
The introduction of Army Order 60 of 1947 was a significant attempt to formalise this situation by creating a structured trade classification system. The order established a comprehensive framework of trade groups (A–D), star classifications, and promotion pathways, linking technical proficiency to advancement and standardising training across the Army.[10]
However, the detail of the order reveals the extent to which trades remained distributed rather than corps-specific. Trades such as fitters, electricians, clerks, storemen, and even ammunition-related roles were not confined to a single corps but were found across RNZAOC, RNZASC, RNZEME, RNZE, WAAC, and others.
For example:
“Storeman” appears in multiple contexts, including RNZASC (supplies) and RNZEME (technical stores)
Clerks remained an “All Arms” function rather than an ordnance-specific trade
Ammunition-related roles existed alongside both ordnance and technical organisations
Technical trades such as fitters, electricians, and instrument mechanics were shared across engineering and transport organisations
This distribution reflects a Commonwealth-wide approach, in which capability was grouped by function rather than by rigid corps ownership. In the New Zealand context, it also highlights a system still settling after wartime expansion, in which RNZAOC’s responsibility was defined more by what it did than by what it exclusively owned.
Crucially, while AO 60/47 imposed a formal structure, its implementation lagged behind in its intent. Training was conducted through district schools and correspondence systems, promotion required both academic and trade testing, and classification was tied to star grading. Yet this system was still bedding in and far from universally applied in practice.
At the unit level, older Quartermaster-based arrangements remained firmly in place. The persistence of roles such as “Storeman, Technical”, explicitly noted as being assessed at the unit level rather than centrally, is particularly revealing. These positions indicate that units retained direct responsibility for certain categories of stores, especially technical and operational equipment, outside the fully centralised ordnance system.
This created a layered system of responsibility:
RNZAOC depots and organisations held national stocks, managed accounting, and controlled distribution
Other corps, particularly RNZEME and RNZASC, held and managed specialist or functional stocks aligned to their roles
Units retained immediate control over equipment required for training and operations, often through Quartermaster systems.
The boundary between these layers was not clearly defined. Instead, it was negotiated in practice, shaped by availability, geography, and operational need.
The result was a system that was centralised in intent but decentralised in execution.
Rather than a clean division between Corps responsibility and unit responsibility, the post-war RNZAOC operated within a hybrid framework:
formal trade structures existed, but were not yet fully embedded
corps responsibilities were defined, but not exclusive
unit-level systems persisted alongside centralised control
This overlap was not simply inefficiency; it was a transitional phase. The Army was moving from a wartime model, built on rapid expansion and functional necessity, toward a peacetime system based on standardisation, professionalisation, and clearer institutional boundaries.
A System in Transition
The NZAOC had been hollowed out before the war, rapidly expanded to meet wartime demands, and was now adapting to the requirements of a smaller, permanent force.
At the same time, it was resisting a return to the pre-war model of civilianisation, retaining military control over supply functions that had previously been outsourced. This placed it at the centre of a broader institutional shift toward professionalised, uniformed logistics.
Complicating this transition was the emergence of new corps boundaries, particularly with the formation of RNZEME, which began to draw clear lines around technical responsibilities that had previously, at least in part, sat within ordnance structures.
Beneath this, however, the system remained far from fully integrated. Unit-level Quartermaster arrangements persisted, local equipment holdings continued, and roles such as “Storeman, Technical” demonstrated that responsibility for stores was still distributed across corps and units rather than cleanly centralised.
The introduction of formal trade classification under Army Order 60 of 1947 provided a framework for standardisation, but its implementation lagged behind intent. Trades remained dispersed across corps, training systems were still bedding in, and practical responsibility continued to be shaped by function rather than doctrine.
The result was a system that was centralised in design but decentralised in execution.
Rather than a stable, clearly bounded organisation, the RNZAOC of this period operated within a hybrid framework, part wartime legacy, part peacetime reform. Its structures, responsibilities, and professional identity were still being defined.
Comparative Context: British and Commonwealth Ordnance Systems
The experience of the RNZAOC during this period reflects a broader Commonwealth pattern. Other ordnance corps faced similar challenges in transitioning from wartime expansion to peacetime structure.
In the United Kingdom, the Royal Army Ordnance Corps (RAOC) underwent large-scale wartime expansion and subsequent post-war rationalisation. At the same time, the formation of the Royal Electrical and Mechanical Engineers (REME) in 1942 formalised the division between supply and repair earlier than in New Zealand. While the conceptual separation was clear, practical implementation still took time, particularly in overseas commands.[11]
In Australia, the Royal Australian Army Ordnance Corps (RAAOC) experienced a similar pattern of wartime growth followed by contraction. Like New Zealand, Australia faced the challenge of maintaining capability within a reduced peacetime force, resulting in continued overlap between unit Quartermaster systems and Corps-level supply structures.[12]
Canada’s Royal Canadian Ordnance Corps (RCOC) followed a comparable trajectory, integrating wartime expansion into a smaller peacetime establishment while redefining responsibilities between supply and maintenance.[13]
What distinguishes the New Zealand experience is not the nature of the challenges, but their scale. With limited resources and a smaller force, the RNZAOC had less capacity to maintain parallel systems, making the tensions between centralisation and decentralisation more pronounced.
Conclusion
The RNZAOC of 1946–1948 represents a critical transitional phase in New Zealand’s military logistics history. It was neither a simple contraction from wartime expansion nor a return to the pre-war, partially civilianised model. Instead, it was a deliberate and, at times, uneasy reconfiguration of a system that had proven its value in war and could not be allowed to regress.
What emerged was not a settled organisation, but a hybrid. Centralised structures were established at the national level, yet unit-level Quartermaster systems persisted. Formal trade frameworks were introduced, yet practical responsibility remained distributed. The separation between supply and maintenance was defined in principle, but evolving in practice.
These tensions were not signs of failure, but of transition. The Army was moving from a system built on wartime necessity toward one grounded in peacetime efficiency and professionalisation, without losing the capability that war had demanded.
In this sense, the RNZAOC was not simply adapting to peace; it was redefining its role within a modern Army. The structures, relationships, and compromises established during this period would endure, shaping the evolution of New Zealand’s military logistics system well beyond the immediate post-war years.

During the Second World War, the New Zealand Army underwent a remarkable transformation. From a force equipped with just 62 vehicles in 1939, it expanded to more than 22,000 by 1944. This rapid mechanisation did not simply increase mobility; it created an entirely new logistical problem: how to sustain, repair, and recover that fleet across dispersed and often austere operational environments.
The answer lay in the development of mobile technical vehicles, purpose-built workshop lorries that brought engineering and technical capability forward to the point of need. Initially managed under the Mechanical Transport (MT) Branch, this capability was formalised post-war with the establishment of the New Zealand Electrical and Mechanical Engineers (NZEME) in 1946, which became the Royal New Zealand Electrical and Mechanical Engineers (RNZEME) in 1947.
It is important to note that this discussion primarily reflects the development of the New Zealand Army within New Zealand itself. At the same time, the 2nd New Zealand Expeditionary Force (2NZEF) was undergoing a concurrent and equally significant transformation in the Middle East and, later, in Italy, developing its own workshop systems and technical capabilities in response to operational demands in those theatres.
These vehicles, and the system behind them, formed the backbone of field maintenance and technical support.
From Introduction to Deployment: A Compressed Timeline
The technical vehicles described in this article were largely received into New Zealand service between 1941 and 1942, as part of the broader influx of modern equipment from Britain, Canada, and the United States.[1]
What followed was a remarkable achievement as within a period of roughly 12 to 24 months, New Zealand:
Absorbed an entirely new class of specialised vehicles
Developed training systems for their operation and maintenance
Built the trade structure required to employ them effectively
Deployed them on active operations with the 3rd New Zealand Division by 1943
This stands in stark contrast to modern capability introduction timelines, where the fielding of new equipment, training, and integration can take many years.[2]
In wartime conditions, necessity compressed what would now be a decade-long capability development cycle into little more than a year.
A Modular System Built for War
New Zealand’s technical vehicle fleet was built on a simple but highly effective principle, common across the British Commonwealth: the machinery type defined the capability, while the chassis provided the mobility.[3]
Workshop bodies were standardised and coded (A, B, D, F, H, I, J, K, L, M, Z), while chassis varied depending on availability. Vehicles in New Zealand service included Ford, Chevrolet, GMC, Leyland, Crossley, Karrier, Austin, and later Bedford and Commer. This modular system allowed:
Rapid integration of Allied-supplied vehicles
Standardisation of workshop capability
Reuse of workshop bodies across multiple vehicle generations
Machinery Types
The Machinery Type system defined both the physical configuration and the technical role of each vehicle.
Role: Versatile repair and reconditioning across multiple echelons.
Type Z – Wireless and Electronics Workshop
Type Z (14 ft)
Body: Steel, house-type, interference-screened
Equipment: Generator, selenium charger, transformer, wavemeter, oscillograph, signal generators
Type Z Mk II (12 ft)
Equipment: Onan generator, oscilloscope, valve test sets, control panels, diagnostic tools
Type Z Light
Body: Heavy utility vehicle with screened windows
Equipment: Generator, transformer, test panels, megger, electrical bridges
Role (All Type Z): Testing, calibration, and repair of wireless and electronic equipment.
Evidence from the Field
Photographic evidence from the 3rd New Zealand Division in the Pacific confirms how these vehicles were used in practice.
A vehicle clearly marked “Machinery Lorry Type A” shows a fully deployed fitter’s workshop, complete with pedestal drill, bench tools, and fold-out work surfaces.
The adjacent vehicle, equipped with machinery, is likely a Type M or Type M, indicating layered repair capability.

These images demonstrate that the system was not static. It was designed to scale from mobile repair to fully developed workshop installations.
Confirmed New Zealand Fleet (1950)
A 1950 Return of Military Vehicles (Form MT 18A) confirms types A, F, H, I, K, M & Z in New Zealand service across a wide range of chassis, including Austin, GMC, Leyland (including Leyland NZ), Crossley, Karrier, Ford, and Chevrolet.[4]

This demonstrates that New Zealand operated a fully developed, multi-echelon technical support system, aligned with Commonwealth practice and sustained into the post-war period.
Post-War Evolution
With the establishment of RNZEME in 1947, this system became institutionalised.

1960s–1970s: Transfer of workshop bodies onto Bedford RL trucks, extending service life
1980s: Replacement by 13-foot containerised workshop shelters, marking the shift to modular, platform-independent systems
Conclusion
The technical vehicles of the New Zealand Army during the Second World War represent far more than a collection of specialised lorries. They formed part of a deliberately structured and rapidly developed system of battlefield sustainment, built around the Machinery Type concept and adapted to the realities of global war.
Within New Zealand, this system was introduced between 1941 and 1942, absorbed and operationalised in an exceptionally short period, and deployed with the 3rd New Zealand Division by 1943. At the same time, the 2nd New Zealand Expeditionary Force was undergoing a parallel transformation in the Middle East and Italy, developing its own workshop capabilities under different operational pressures. Together, these efforts reflect a wider national adaptation to mechanised warfare, achieved at a pace that remains striking by modern standards.
What emerged was not simply a fleet of workshop vehicles, but a layered, multi-trade capability integrating mechanical, electrical, fabrication, and electronic support. The system was inherently modular, separating function from platform, and scalable, able to transition from forward repair elements to fully developed semi-permanent workshop installations as operations evolved.
Its longevity reinforces its effectiveness. From wartime deployment through post-war refinement under RNZEME, to re-platforming on Commer and Bedford RL chassis, and ultimately to containerised workshop systems in the 1980s, the underlying principles endured even as the technology changed.
As demonstrated throughout this article, and supported by photographic and documentary evidence, these vehicles ensured that New Zealand’s mechanised force could not only move but also endure, adapt, and remain operational under demanding conditions.
At the same time, this study represents only an initial snapshot of New Zealand’s technical vehicle capability during the period. Much remains to be explored, particularly in linking specific Machinery Types to trades, units, and operational employment, and in tracing the full evolution of these systems across both theatres of war. Further research will continue to refine and expand this picture, contributing to a more complete understanding of how New Zealand sustained its forces in the field.
