The USS Phoenix submarine is met by the Peace Squadron as it arrives in Waitemata harbour, Auckland on 9 November, 1983. The growing anti-nuclear movement in New Zealand was hostile to visits from US ships because the Americans refused to confirm or deny whether their ships carried nuclear weapons. Public opinion was increasingly in favour of banning these visits. Between 1978 and 1983 opposition to nuclear-armed ship visits rose from 32% to 72%. In 1985 the Government effectively banned nuclear ship visits. New Zealand was the first country to declare itself nuclear free when it passed legislation in 1987.
