Cold War abates
For much of the Cold War (the latent conflict between the Soviet Union and the US, which began after the Second World War) New Zealand was aligned with the US on security, economic and political fronts. However, by the mid-1970s it appeared as if this international conflict was coming to an end. In the Asia–Pacific region the Vietnam War was over and the anti-communist South-East Asia Treaty Organization had collapsed. The division of the world into Eastern and Western blocs seemed much diminished. Norman Kirk’s Labour government, elected in 1972, took advantage of this new mood by protesting against French nuclear-weapon tests in the Pacific, and by not inviting nuclear-propelled American vessels to visit.
The Soviet Union’s 1979 invasion of Afghanistan and the 1980 election of US President Ronald Reagan, who was determined to strengthen international opposition to communism, saw a reigniting of Cold War tensions. New Zealand peace groups strongly supported their European counterparts, who were campaigning against the stationing of American nuclear weapons on their territory. David Lange’s Labour government was elected in 1984 on a platform that included establishing New Zealand as a nuclear weapon-free zone.
Many, if not most, New Zealanders wanted to have a nuclear-free policy while remaining part of the ANZUS alliance. However, the US saw this as an unexpected hardening of New Zealand’s position, leading to a breakdown in US–New Zealand security ties. In 1985 the Labour government declined an American request for a visit to New Zealand by the USS Buchanan, on the basis that it might be capable of carrying nuclear weapons. The US, worried that some of its more important allies – especially the strongly non-nuclear Japan – might copy the New Zealand example, was unwilling to confirm or deny that this was the case.
The sniff test
Although David Lange often said that New Zealand’s nuclear policy was not for export to other countries, he did accept invitations to participate in the international disarmament debate. Lange took part in an Oxford Union debate in 1985, remarking at one point that he could smell the uranium on the breath of a member of the opposing team.
End of ANZUS
In 1987 New Zealand’s Parliament enacted legislation that denied access to New Zealand’s internal waters to vessels which were propelled by nuclear power or might be carrying nuclear weapons. By this time the US had suspended security cooperation with New Zealand under ANZUS. New Zealand would now be classified as a friend, not an ally. Any military cooperation between the two countries required a special waiver from the US government.
New Zealand debate
New Zealand opinion was divided on this foreign-policy turning point. Many celebrated the non-nuclear policy and the willingness to say no to the world’s leading power as a sign of an independent foreign policy. They saw New Zealand as gaining a unique profile on the international stage. Supporters of the non-nuclear position also suggested that by standing up to the US New Zealand would be able to shape new relationships in Asia, and have more freedom to decide whether or not to contribute to American military actions.
Others believed the breach in the relationship seriously harmed New Zealand’s interests. They suggested that the armed forces suffered by being denied regular opportunities to train with the US military, and pointed to the complications for New Zealand’s important relationship with Australia. They claimed that New Zealand had become a free rider on, rather than a contributor to, the security that the US and its allies brought to the Asia–Pacific region, and that the country had lost credibility in Asia. They also argued that even when part of an alliance, New Zealand sent forces abroad on the basis of its own national interests.
Trade and culture
Despite the conflict, trading and cultural relationships with the US were little affected. The proportion of imports from, and exports to, the US in 1990, the last year of the Labour government, was higher than in 1984, before the crisis erupted. In addition, Labour’s policy of selling state-owned assets attracted investment from the US, especially in Telecom and New Zealand Rail.
