From four Stores Depots in the main centres of New Zealand at the beginning of the 20th century, the Royal New Zealand Army Ordnance Corps (RNZAOC) expanded and shrank to meet the operational needs of the NZ Army, Ordnance units have been deployed worldwide and across the breath and width of New Zealand.

In general terms Ordnance units can be described as:

• Main/Base Depots – A battalion-sized unit, commanded by a lieutenant colonel. Usually a major stock holding unit, responsible the distribution of stock to other ordnance installations.
• Central Ordnance Depots/Supply Company – Company-sized units, commanded by a major. depending on the role of the unit, the following sub units could be included in the organisation:
  • Provision, Control & Accounts
  • Stores sub-depot/platoon
    • Traffic Centre
    • Camp Equipment
    • Technical Stores
    • Expendables
    • Clothing
    • Returned Stores & Disposals
      • Textile Repair
      • Tailors
      • Boot Repair
  • Ammunition Sub-Depot/Platoon
  • Vehicles Sub-Depot/Platoon
  • Services Sub-Depot/Platoon
    • Bath and Shower
    • Laundry
  • Rations Sub-Depot/Platoon (after 1979)
    • Fresh Rations
    • Combat Rations
    • Butchers
  • Petroleum Platoon (after 1979)
• Workshops Stores Sections – In 1962, RNZAOC Stores Sections carrying specialised spares, assemblies and workshops materials to suit the particular requirement of its parent RNZEME workshops were approved and RNZEME Technical Stores personnel employed in these were transferred to the RNZAOC.^[1]
• Workshops Prior to 1947, Equipment repair workshops were part of the Ordnance organisation, types of workshop included:
  • Main Workshop
  • Field Workshop
  • Light Aid Detachments
  • Technical Stores

Naming of Ordnance units within New Zealand was generally based upon the unit locations or function or unit.

Supply Depots were initially named based on the district they belonged to:

• Upper North Island – Northern District Ordnance Depot
• Lower North Island – Central Districts Ordnance Depot
• South Island – Southern Districts Ordnance Depot

In 1968 a regional based numbering system was adopted

• 1 for Ngāruawāhia
• 2 for linton
• 3 for Burnahm
• 4 for Waiouru

Some exceptions were:

• 1 Base Depot and 1st Base Supply Battalion, unique battalion sized unit, name was based on role not location
• 1 Composite Ordnance Company, a unique company sized unit, name was based on role not location

When the Royal New Zealand Army Service Corps(RNZASC) became the Royal New Zealand Corps of Transport (RNZCT) in 1979, the supply functions were transferred to the RNZAOC with the 1st number signifying the location with the 2nd number been 4 for all Supply Platoons:

• 14 Supply Platoon, Papakura
• 24 Supply Platoon, Linton
• 34 Supply Platoon, Burnham
• 44 Supply platoon, Waiouru
• 54 Supply Platoon, Trentham

Exceptions were:

• 21 Supply Company – Retained its name as a historical link to the units long history in the RNZASC.
• 47 Petroleum Platoon, Originally 7 Petroleum Platoon RNZASC, when Transferred to the RNZAOC, as it was based in Waiouru it added the Waiouru unit designation 4 and became 47 Petroleum Platoon RNZAOC
