and a half years taking part in the operations which led the United Nations forces back to and over the 38th Parallel, later recapturing Seoul in the process. The majority of Kayforce had returned to New Zealand by 1955, though it was not until 1957 that the last New Zealand soldiers had left Korea. In all, about 4700 men served with Kayforce. In 1957, the 9th Coast Regiment, Royal New Zealand Artillery, was reduced to a cadre along with the other coastal artillery regiments (10th and 11th). Personnel were gradually run down until there was only a single supervisory District Gunner.

A Special Air Service squadron was raised for this commitment, but most forces came from the New Zealand infantry battalion in the Malaysia–Singapore area. The battalion was committed to the Far East Strategic Reserve. The 1957 national government defence review directed the discontinuation of coastal defence training, and the approximately 1000 personnel of the 9th, 10th, and 11th coastal regiments Royal New Zealand Artillery had their compulsory military training obligation removed. A small cadre of regulars remained, but as Henderson, Green, and Cook say, 'the coastal artillery had quietly died.' All the fixed guns were dismantled and sold for scrap by the early 1960s. After 1945, the Valentine tanks in service were eventually replaced by about ten M41 Walker Bulldogs, supplemented by a small number of Centurion tanks. Eventually, both were superseded by FV101 Scorpion armoured reconnaissance vehicles. Vietnam War New Zealand sent troops to the Vietnam War in 1964 because of Cold War concerns and alliance considerations. Initial contributions were a New Zealand team of non-combat army engineers in 1964 followed by a battery from the Royal New Zealand Artillery in 1965 which served initially with the Americans until the formation of the 1st Australian Task Force in 1966. Thereafter, the battery served with the task force until 1971. Two Companies of New Zealand infantry, Whisky Company and Victor Company, served with the 1st Australian Task Force from 1967 until 1971. Some also served with the Australian and New Zealand Army Training teams until 1972. NZ SAS arrived in 1968 and served with the Australian SAS until the Australian and New Zealand troop withdrawal in 1971. Members from various branches of the NZ Army
