This undated plan of the Mount Eden Goal Reserve provides a view of the layout of the long-forgotten Auckland Defence Stores Mount Eden location. Located between the Goal and Auckland Grammar School, this plane was drawn up sometime between 1907 and 1917

The Defence Stores footprint at Mount Eden started in 1871 when two magazines were constructed to house Defence ammunition, then stored at Albert Barracks in the centre of Auckland.

In 1903 the Defence Stores Office in O’Rourke Street (now Auckland University) was relocated to Mount Eden. Initially, the existing magazines at Mount Eden were thought to be sufficient. However, it was soon found that additional buildings were required, and a Stores building and Armourer’s shop were constructed during 1903/04. Eventually, a house was also built for Captain W.T Beck, the District Storekeeper.

In 1917 the Defence Stores were reorganised into the New Zealand Army Ordnance Corps (NZAOC), with the Mount Eden Defence Stores becoming the Northern Districts Ordnance Depot.

By 1920, with little space available for expansion to allow the storage of the large number of mobilisation stores required by the Norther District, construction of an alternative site for the Mount Eden Ordnance Depot began at Hopuhopu in the Waikato.

While the Hopuhopu site was still under construction, Stores from the Mount Eden site began to be transferred to Hopuhopu in 1927. The new depot officially opened in 1929, with the Mount Eden Depot closing.

The Store constructed in 1903 was dismantled and re-erected at the Narrow neck Camp on Auckland’s North Shore. The fate of the original magazines is unknown, but they were likely taken over for a time by the nearby Colonial Ammunition Company (CAC).

The closure of the Mount Eden Depot did not totally sever to the connection between Mount Eden and the Ordnance Corps, with Ordnance Ammunition staff remaining attached to the CAC until 1967, testing the supply of Small Arms Ammunition provided by that factory.
