New Zealand Force South East Asia (NZFORSEA) (1974–1989) comprised the elements of the Royal New Zealand Navy, New Zealand Army and Royal New Zealand Air Force. Much of the New Zealand military left Singapore as part of operation Kupe in 1989, leaving behind a residual Defence Support Unit (NZDSU).

ANZUK was a tripartite force formed by Australia, New Zealand, and the United Kingdom to defend the Asian Pacific region after the United Kingdom withdrew forces from the east of Suez in the early 1970s. The ANZUK force was formed in Singapore on 1 November 1971 under Rear Admiral David Wells and disbanded on 31 January 1974.
