Ordnance Activities July 1921 – June 22
The handing-over of the military hospitals to the Health Department, the closing of the Ordnance Depot at Dunedin, the merging of the Palmerston North Depot with the Main Ordnance Depot at Trentham, and the disposal of large stocks of surplus and obsolete stores made a considerable reduction in the NZAOC, the financial situation necessitated a far larger reduction than was warranted by the above economies. In addition to the routine duties connected with the stores, equipment, and clothing for the Territorial Force and Senior Cadets and the management of mobilization equipment, the NZAOC was also dealing with;
- the examination of stores received from the United Kingdom,
- the marking and issuing of new guns, stores, and rifles,
- the disposal of surplus stores, and
- the pricing of all issues and receipts in accordance with the implementation of a new system of cost accounting.
It was recognised that once these extra duties had been completed, and when proper accommodation was provided at each command depot, it would be possible to make a further reduction in personnel, but it was considered at the time that any reduction would lead to neglect and a consequent depreciation of stores. Against the possibility of reduction, it was recognised that the present system of stores audit would almost certainly necessitate an increase in the clerical stall.
In 1919, the NZAOC 532, and by March 1922 had been reduced to 100. The civil staff of the NZAOC .which stood at 520 in 1919, had been reduced to 95.  On 4 May 1922, a further 25 N.C.O.’s and men of the NZAOC received notice of their dismissal.
With Ordnance Depots established at Burnham for the Southern Command, and at Trentham for the Central Command. The site for the Northern Command Depot at Ngaruawahia had been obtained with the exchange with the Railway Department for land at Frankton Junction. The mobilization stores for the Northern Command were held at Trentham and Featherston so it became a priority to incur some expenditure for the erection of buildings at Ngaruawahia. Plans were also on the table for the provision of suitable fireproof buildings to replace the present temporary accommodation at Trentham and Burnham. At Trentham all available buildings, including the gymnasium used by the School of Instruction, were utilised for storage; many of the older hutments were not suitable for storing the very valuable, equipment on charge, and the risk of fire is a very grave one.
The Ordnance Depot in each command was to hold the stores and equipment required by the Territorial units in that command; additionally, Trentham will hold, the general reserve of stores and equipment. All stores surplus to mobilization requirements were in the process of being disposed of. Disposal-depots were continued in the four centres, after which a series of country sales were held in various towns. Owing to reduced staff it was eventually found necessary to restrict activities to a central depot in Wellington, which commenced operation on February 1922. The Wellington Disposal Depot conducted over the counter sales which were restricted to one day weekly, with postal orders being dealt with on other days. The total sales of clothing and miscellaneous stores during the period 1st April 1921 to 31st March 1922, amounted to £177,346.
The Magistrates Court hear a case on 24 November 1921 resulting from the theft of items from Trentham Camp. Civilian labourer Phillip Frederick Deihert pleaded guilty to the theft of Military stores a portion of which included; two tents, an anvil, a forge and eight military overcoats. Deihert was committed to the Supreme Court for sentencing at a later date.
Corporal John Wilson Robertson, Head packer in the Receipt and Issue store, was also charged with the theft of one of the tents, but the case against him was dismissed, as the evidence that he was knowingly involved was not sufficient to warrant prosecution. Despite the dismissal of the case against Robertson, his character and suitability for further employment in the NZAOC was under question and he was demobilised as part of the compulsory reductions that the NZAOC was forced to carry out.
