The ANZUK force was formed in Singapore on 1 November 1971 under Rear Admiral David Wells and disbanded on 31 January 1974.

The Royal New Zealand Infantry Regiment is the parent administrative regiment and corps of regular and reserve infantry battalions in the New Zealand Army. It was originally formed in 1947 with a singular Regular regiment and multiple reserve regiments. Over time, the regiments were turned into battalions, the reserve units amalgamated and more regular units raised and disbanded. Currently, the Regiment currently consists of two regular and three reserve battalions. Throughout its existence, units raised in this regiment have served and deployed on operations in Malaya, Vietnam, Borneo and various United Nations peacekeeping operations.
