The involvement of New Zealand in the Korean War began in 1950 as a response to the United Nations Security Council's call for combat assistance in the erupting Korean War. New Zealand was one of the first (of a total of sixteen) nations to respond with support.

On 29 June 1950, just four days after 135,000 North Korean troops crossed the 38th parallel in Korea, the New Zealand government ordered two Loch class frigates of the Royal New Zealand Navy – Tutira and Pukaki to prepare to make for Korean waters, and for the whole of the war, at least two NZ vessels would be on station in the theater.

On 3 July, these two first ships left Devonport Naval Base, Auckland and joined other Commonwealth forces at Sasebo, Japan, on 2 August. These vessels served under the command of a British flag officer (seemingly Flag Officer, Second-in-Command, Far East Fleet) and formed part of the US Navy screening force during the Battle of Inchon, performing shore raids and inland bombardment. Further RNZN Loch class frigates joined these later – Rotoiti, Hawea, Taupo and Kaniere, as well as a number of smaller craft. Only one RNZN sailor, Able Seaman R.E. Marchioni, was killed throughout the conflict; during a raid on Sogon-ni on 26 August 1951 with HMNZS Rotoiti.
