RNZN were involved in the mutinies. The resulting manpower shortage forced the RNZN to remove Black Prince, one of their most powerful warships, from service, and set the navy's development and expansion back by a decade. Despite this impact, the size and scope of the events have been downplayed over time. Korean War Six s were deployed during the Korean War; HMNZ Ships , , , , , and . RNZN crews in Korea went ashore in several "Nelsonian" night raids against coastal targets and took several prisoners for intelligence gathering. Vietnam War RNZN medical personnel were members of the 1st New Zealand Services Medical Team (NZSMT) in Vietnam, a 19-strong detachment of medical personnel from the Royal New Zealand Navy, Royal New Zealand Air Force, and Royal New Zealand Army Medical Corps deployed in April 1967.

In 1984, the relationship began to break down over the issue of nuclear-powered ship visits and nuclear weapons access to New Zealand. On several occasions, New Zealand dispatched RNZN vessels to monitor environmental damage caused by French nuclear testing in the Pacific. East Timor The RNZN supported INTERFET landings with the deployment of frigate and the tanker . Te Kaha was later replaced by the Leander-class frigate , which escorted the Australian landing ship to Suai, with elements of the New
