The strength of the NZAOD/NZAOC on 30 June 1920 was 3391, consisting of;
- Officers, 14;
- Other ranks, 377
Despite pressure to reduce manning levels, it had not been possible to reduce the NZAOD/NZAOC to a greater extent owing to the large amount of work still required to be carried out in connection with the war. In addition to the ordinary ordnance work in connection with the Territorial Force, the NZAOD/NZAOC was required to;
- maintain extra personnel for the handling, storage and accounting of hospital equipment for the hospitals under the Defence Department,
- maintain extra personnel for the educational and vocational establishments,
- Handle the large quantity of military equipment arriving from overseas.
Until the hospitals were transferred to civil control, and the Vocational Training Branch took over by the Repatriation Department, and the military equipment for the Military Force distributed in accordance with future requirements, NZAOD/NZAOC personnel reductions were unable to be reduced to any great extent without serious risk of incurring inefficiency and loss of stores.

NZAOC appropriations year ending 31 March 1920
This period would see the NZAOC undergo a change of command and re-designation of appointments to bringing it into line with the current RAOC naming conventions. The Director of Equipment and Ordnance Stores (DEOS) would be renamed and Director of Ordnance Services (DOS) and the position of Chief Ordnance Officer (COO) created. The Division of duties between the DOS and COO was that the DOS would have executive command of the NZAOD/NZAOD with the COO would be the Commanding Officer of the NZAOC and would manage the day the day Administrative functions. 
Major T McCristell who had held the position of DEOS since 1916, would become the COO and the position of DOS filled by Lieutenant Colonel H. E. Pilkington, RNZA. Lt Col Pilkington had spent the war filling a variety of Ordnance Positions in the NZEF and Brutish Army including time as the ADOS of 19 Corps and ADOS of the NZEF. McCristell’s tenure as COO would be brief as he would be seconded to the Audi Department, relinquishing the position of COO to Captain T.J King in April 1920. 
The revenue generated by the NZAOC for the year ending 31st May 1920, was £49,013 17s, 4d., while approximately £90,000 was saved by the renovation of part-worn uniforms.
Review of the NZAOC Establishment
It was announced on the 4th of July 1920 that a board of officers was to assemble at General Headquarters for the purpose of inquiring into the establishment of the NZAOC, with a view to its reduction and the practicability of the substitution of a percentage of civilian staff or permanent staff. The board will be composed as follows:
- Lieutenant-Colonel H. E. Pilkington, CBE. (Director of Ordnance Services);
- Lieutenant Colonel C. E. Andrews, OBE
- Lieutenant Colonel H. E. Avery, G.M.G, DSO
The war revealed the requirement for maintaining an adequate supply of war material to ensure the equipping the Territorial Army on mobilisation. The deficiency of war material in the Dominion in 1914 necessitated the original Expeditionary Force being sent overseas incompletely equipped, while the shortage of military stores in New Zealand during the war became a serious handicap to the training of both the Territorial Force and the drafts for the Expeditionary Force.
The military equipment which was used by the NZEF abroad had been handed back to the Imperial authorities, and a supply of new or serviceable equipment to reequip the New Zealand Army issued in lieu, and gradually shipped to New Zealand as shipping became available. The need for storage accommodation for this equipment was very great, and although temporary arrangements were made to store it in wooden hutments at Trentham and Featherston Camps, these buildings were not suitable for storage of valuable equipment, nor were they conveniently situated for mobilization. Recommendations were made for district mobilization stores to be constructed, in order that this valuable equipment may not deteriorate and that each district may be self-contained.
Fiji Expeditionary Force
Early in 1920 New Zealand dispatched Force of Fifty-Six regular soldiers to Fiji on the NZ Government Steamer Tutanekai. This Small force was sent at the request of the Governor of Fiji to provided support to the limited Police resources at his disposal to manage a strike among Indian indentured labourers and sugar cane farmers. The first peacetime deployment of New Zealand Forces, it was mainly made up of members of the RNZA and served in Fiji between 3 February -28 April 1920 and was known as the Fiji Expeditionary Force. 
Included as part of Fiji Expeditionary Force was a small NZAOC Detachment, which included the following personnel;
- Staff Sergeant Joseph Warren.
Annual Christmas Leave
A definite arrangement was made by the Defence Department regarding the annual leave of members of the NZAOC. Annual leave would be taken by the NZAOC as follows;
- The first party would take leave on December 4 and return to duty on December 28.
- The second party would go on leave on December 3O and return to duty on January 22.
On 3 July 1919 Captain A. Duvall, of the NZAOC was found dead in the laboratory room at the Colonial Ammunition Company, the cause being a bullet wound. He was the Proof officer for the Defence Department at Auckland, it being his duty to test ammunition. He was aged fifty and left a widow, but no children. The coroner returned a verdict that death was the result of gunshot wound apparently self-inflicted while in a state of nervous depression.
Lance Corporal Duncan Macgregor of the NZAOC passed away at the comparatively early age of 54 years at Wellington on 25 July 1919. A well-known figure in local military circles, LCpl Macgregor had been a member of the Argyle and Sutherland Highlanders, gaining decorations for conspicuous bravery in India and South Africa.

Provisional Dress Regulations
Provisional dress regulations for the New Zealand Permanent Forces were issued in early 1920. The revised regulations detailed that the Director of Ordnance would wear the following dress distinctions; 
- Blue Gorget patches (tabs), and
- blue cap-bands
529 Private Samuel McShane, of the NZAOC was tried by District Court-martial on 23 September 1919 at Trentham Camp on charges of receiving public goods knowing them to have been stolen and was sentenced to 90 days’ imprisonment. His sentence remitted, Pte McShane was immediately demobilised with no demobilisation pay or privileges.
Serious charges were laid against 605 Conductor Walter Edward Cook, NZAOC (Temporary) of the Featherston Ordnance Detachment at the Magistrate’s Court on 18 June 1921. In outlining the case and explaining the charge; the theft of £2 11s 9d (approx. 2018 NZ$290), the property of the Government, Detective-Sergeant Lewis said that it had been a part of the accused’s duty to audit certain, accounts regarding the sale of blankets. It was alleged that Cook had altered a number of dockets, pocketed a part of the money, and then forwarded the altered dockets. The total sum involved was about £177 (approx. 2018 NZ$17000). Cook was later found guilty, reverted in rank to Private and demobilised with no demobilisation pay or privileges and sentenced to six months hard labour.
