Throughout the early 1860s, elements from the Militia and Volunteers supported the Imperial troops undertaking the bulk of the military operations in the early years of the New Zealand Wars. In 1861 as George Grey assumed the role of Governor for a second term, Grey undertook a policy of conciliation while also preparing for war. As General Cameron built up his Imperial forces, Gray reviewed and overhauled the citizen forces of New Zealand. In January 1862, new regulations for the volunteer force were issued, followed on 18 September by the Colonial Defence Act of 1862. This Act saw the formation of the Colonial Defence Force, the first regular Force in New Zealand. Under the Quartermaster General of the Colonial Defence Force, Captain Robert Collins, the Colonial Store Department and the Militia Store Department assumed the store’s responsibility for the Militia, Volunteer and Regular Forces of New Zealand.
In Auckland, the Colonial Store Department and the Militia Store Department initially operated out of offices on Princes Street. However, approval was granted in October 1863 for the erection of a store adjacent to the Imperial Armoury near the Symonds street entrance to the Albert Barracks. The two Store Departments essentially carried out the same functions, and in 1865 the post of Superintended of Militia Stores held by Mr E.D King was disestablished with the responsibility for colonial defence stores centralised under the Colonial Storekeeper, Captain John Mitchell.
A review of colonial defence with a reliance on local forces taking over from Imperial Forces saw the passing of the Armed Constabulary Act of 10 October 1867. This Act combined police and military functions into the regular Armed Constabulary (AC) Force. The AC Force was supported by Maori loyal to the crown, Militia and Volunteer units, with Defence Storekeepers in Auckland, Whanganui and Wellington providing the required logistic support.
In April 1869, Lieutenant Colonel Edward Gorton was appointed as the Inspector of Defence Stores, establishing his office at Molesworth Street in Wellington, bringing all New Zealand’s Defence storekeepers under his control. By January 1869, as the withdrawal of Imperial units became imminent, the dismantling of their central logistic hub at Auckland’s Fort Britomart and Albert Barracks had commenced, with military stores, including guns and ammunition that were not auctioned off to the public or purchased by the New Zealand Government, shipped to the United Kingdom. The departure of the British Military Storekeeper Joseph Osbertus Hamley in July 1870 marked the final withdrawal of Imperial Forces from New Zealand, with the Auckland Defence Store taking over ownership of the Armoury and Magazines located in Albert Barracks.
In May 1869, Captain John Mitchell was suspended as the Auckland Storekeeper due to unauthorised absences. Resigning in July, Major William St Clair Tisdall replaced Mitchell as acting Storekeeper. A small staff assisted Tisdall, some of whom had served in the stores since 1861, including
- John Blomfield, Clerk
- John Price, Clerk
- David Evitt, Armourer Sergeant
- Arms Cleaners
- Mr’s F Gibbons,
- J Penligan and
- C.C Rockley
Following the departure of Imperial units, the future of Albert Barracks came under debate. In addition to the Defence Stores, the only other military use of the former barracks was by the local Militia and Volunteers, who retained a drill hall and utilised the parade round. The Auckland Improvement (Albert Barrack Reserves) Act of 1872 repealed previous Acts relating to the status of Albert Barracks and placed responsibility for the management and disposal of the land under the Auckland Improvement Commissioners. The Auckland Improvement Commissioners drew up and oversaw plans to develop the bulk of the Barracks into a recreational reserve, with other areas subdivided into roads and plots of land for further development.
By 1871 the growth of Auckland now placed the ageing powder magazine in the centre of a built-up area, raising concerns about its safety. New powder magazines were constructed at Mount Eden, with the first stocks transferred from Albert Park to Mount Eden in September, following which the Albert Barracks magazines were demolished. With the Auckland district’s supply of ammunition now safely stored at Mount Eden under the care of the Defence Stores magazine keeper, Tisdall and the remaining staff of Storemen and Armourers remained at Albert Barracks. Initially located in the old Imperial Armoury building at the Symonds Street entrance of Albert Barracks, it was considered an obstruction to the Commissioner’s projected improvements. To allow the extension of Princes Street and subdivision of the land between Princes and Symonds Street, in July 1873, the Defence Stores had been moved into the well-constructed stone building that had previously been the Barracks hospital. The new building included ample accommodation for warlike stores, including small workshops and a forge. The only remnant of the site of the old Armoury were two Russian 18-pounder guns taken at the Crimea and presented by the Imperial Government to the colony of New Zealand in the late 1850s.
The Defence Stores building in Albert Park was described by the Auckland Star as the “hideous eyesore in Albert Park’ and considered a blight on the skyline as it obstructed the view from the park that had been established to replace the Barracks. By 1883 an agreement was reached between the Auckland Council and the Government, with a plot of land in O’Rourke Street provided to allow the relocation of the Defence Stores.
When the proposal was first mooted to relocate the Defence Store, plans were prepared in the Auckland Public Works office for a three-storied building equal in space to the present location. However, as it intended to centralise the operations of the Defence Stores in Wellington, the original design was countermanded with a design for a smaller building substituted. Tenders for the erection of the new Defence Stores building were published on 10 May 1883 for a building meeting the following specifications,
- to be constructed of brick, two storeys in height, with a concrete foundation,
- to have a frontage of 25 feet with a depth of 36 feet.
- the ground floor was to have
- a passage seven feet wide,
- two 18×18 apartments,
- a staircase leading from the ground floor to the upper storey
- The upper floor subdivided into
- An 18×8 office, compartment with lift,
- a 14 x18 room
- an 11 x 18 room
- To the rear of the building
- a 14×25 shed with an asphalted floor for gun carriages
- a 6×14 coal shed,
- a 14×20 Armourer’s shop.
Due to the considerable amount of material accumulated in the old Defence Stores over its many years of operation, Captain Sam Anderson, the Chief Defence Storekeeper, assisted in a stocktake of the old store as it was decommissioned, ensuring only essential materials were transferred to the new building. Surplus stores were disposed of by tender or redistributed, including over 2000 obsolete muzzle-loading muskets relocated to the Defence Store in Wellington. The old Stores building was soon demolished with much of the material used in the construction of the new building, with the only reminder of the military’s residence of Albert Park being a small portion of the Barracks wall and a few old cannons on display in the new ornamental gardens.
The New Defence Store in O’Rourke Street was one of the earliest purpose-built Storehouses built for New Zealand’s Military. Up to this period, many of the buildings utilised by the Defence Stores were inherited from the Imperial Forces or requisitioned commercial premises.
By 1888, the cost of maintaining a peacetime military had reached the point where cutbacks and savings across the Defence budget had to be made. As part of several reductions across the Defence Department, the Auckland Defence Store was drastically downsized, resulting in the retirement or redundancy of most of the staff. The closure of the Auckland Defence Stores was met with dismay, with the press questioning it as an absurd decision, with the New Zealand Herald noting in an editorial that the closure of the Auckland Defence Store was” solely arising from the Wellington authorities having want of local knowledge and of the requirements of the place.” This pushback on the closure of the Auckland Defence Store resulted in a short reprieve for James Bloomfield, the Defence Storekeeper in Auckland, who had served since 1861, was granted a reprieve from redundancy and allowed to extend his tenure, retiring in December 1888, handing over the responsibilities of Defence Storekeeper for Auckland to Major John William Gascoyne of the New Zealand Permanent Militia. Following Gascoyne’s departure in 1891, the responsibilities of Auckland Defence Storekeeper were assumed by the Adjutant of the Auckland Brigade Office, who oversaw the duties of the Magazine Keeper at Mount Eden, Mr J Hawthorn.
Concurrent with the Adjutant taking over the Defence Storekeepers’ responsibilities, the Auckland Brigade Office was moved from its offices in the Auckland Supreme Court into the Defence Store O’Rourke Street building, from where the Adjutant conducted his duties related to the Auckland Volunteers and the Defence Stores. This shared arrangement remained in place into the early years of the twentieth century and even saw a telephone installed in 1902.
Routine activities conducted by the Auckland Defence Stores in O’Rourke Street included various tenders to provide uniforms and repair equipment. Following the bloodless Dog Tax War of 1898, the Defence Store in O’Rourke street took custody of the surrendered arms, including 
- one Winchester repeating rifle
- one Winchester carbine
- two Green’s American patent Snider breech-loading rifles
- one Snider rifle
- one muzzle-loading carbine
- one Lee Bolt shotgun, single barrel
- three breech-loading single-barrel guns.
- three double-barrel breech loaders (nearly new)
- ten double-barrel muzzle-loading guns
- two single-barrel guns
- four bundles of ammunition (various)
In 1903 the Police expressed an interest in taking over the building as accommodation for the Auckland Police Commissioner. Following an inspection by the Defence Storekeeper, Mr James O’Sullivan, arrangements were made to transfer the Defence Stores from the O’Rourke Street Property to Mount Eden and hand the building over to the Police. In 1904, the Defence Stores building handover to the Police was concluded, ending the sixty-year relationship between Auckland’s Albert Park and the Military.
The Police fully refurbished the former Defence Store Building into a residential villa. The building survived into the 1960s when it was demolished to allow the construction of Auckland University.
Despite the construction of new buildings for the Defence Stores in Wellington, Christchurch and Dunedin during the early 1900s, no new permanent buildings were constructed for the Auckland Defence Stores as the existing powder magazines at Mount Eden, constructed in 1871, were deemed sufficient to meet current and projected needs. Following the transition of the Defence Stores into the New Zealand Army Ordnance Corps in 1917, a new Ordnance Depot was constructed for the Northern Region to replace the infrastructure at Mount Eden in the late 1920s. However, it was not in Auckland but at Hopuhopu in the Waikato. Temporary Ordnance Stores were established in Auckland during World War Two, utilising rented commercial premises. In the post-war era, ordnance warehouses established at Syliva Park utilised buildings constructed for the United States Forces. Besides Explosive Store Houses at Ardmore, no permanent dedicated storage infrastructure was ever constructed for the RNZAOC in Auckland.
The significance of the Defence Store building in O’Rourke Street is that, excluding smaller unit storehouses and ammunition storehouses, it remains the only purpose-built military warehouse constructed for the New Zealand Army in Auckland.
