The development of Ngaruawahia Camp was now in its final stages. During the year the large Ordnance Store building had been completed, and the stores from the Ordnance Depot at Mount Eden were being transferred to it. Two additional short railway-sidings: one off the main siding, and one off the Ordnance Depot siding, to facilitate sorting of trucks and disposal of empties had also been completed. The Ordnance Office was in use, while the Ordnance workshop and small-arms-ammunition magazine areas were approaching completion. Four married quarters for Ordnance personnel were erected and completed during the year. Two high-explosive magazines were completed with an additional three high-explosive magazines and laboratory, and the provision of mains and equipment for fire-prevention nearing completion. 
At Trentham Camp, minor improvements had been undertaken, and the electrical change-over enabling the independent-power plant to be dispensed with was completed. Roads in the camp were receiving attention, while the numerous wooden buildings had been painted and otherwise maintained in good order.
Burnham Camp had been maintained, and the water-supply system completed.
