Nuclear-free New Zealand

Page 4 – Nuclear-free legislation

It was election year in 1984, and Robert Muldoon decided to go to the polls early, on 14 July. This was due partly to a decision by Marilyn Waring, a National Party Member of Parliament, to withdraw her support for the National caucus on 14 June. She had been savagely attacked by Robert Muldoon for supporting the Labour opposition’s Nuclear Free New Zealand Bill the previous day.

Labour campaigned against nuclear propulsion and weapons, but not against ANZUS. The Americans’ ‘neither confirm nor deny’ policy would make it difficult for a Labour government to reconcile these two aims.

Labour swept to power in the election and immediately made clear its intention to pursue policies that would establish New Zealand as a nuclear-free country. This was a popular stand, and by the end of the year nearly 40 towns and boroughs had declared themselves nuclear-free. Labour announced its decision to ban ships that were either nuclear-powered or -armed. The United States maintained its position, and stalemate was quickly reached.

Five days after his defeat in the election, the outgoing prime minister, Robert Muldoon, met the United States secretary of state, George Shultz, who was in Wellington for an ANZUS council meeting. Lange labelled this ‘a calculated attempt to embarrass the new Labour Government’ and declared that the council communiqué was ‘intellectual dishonesty which allowed the representatives of a defeated government to put their country’s name to a document that all who signed it knew did not represent the views of the country’s future government’.

Lange sought to soften Labour Party policy on this issue but found little room to move; party activists were unwilling to draw distinctions between nuclear propulsion and nuclear weapons. The mood of the nation was also turning against such political manoeuvring. Lange had hinted to Shultz that a compromise could be reached, and Shultz believed that he had Lange’s assurance that Labour’s policy could be changed. He later claimed that he felt betrayed by the way things unfolded.

Following confidential discussions over the selection of an acceptable ship, in late 1984 the United States requested that the ageing guided-missile destroyer USS Buchanan visit New Zealand. The Americans hoped that a perception that it was not nuclear-armed would be enough for it to slip under the political radar, and believed they had Lange’s agreement. But on 4 February 1985 the government said no. ‘Near-uncertainty was not now enough for us,’ Lange later explained. ‘Whatever the truth of its armaments, its arrival in New Zealand would be seen as a surrender by the government.’ In response, Washington severed visible intelligence and military ties with New Zealand and downgraded political and diplomatic exchanges. George Shultz confirmed that the United States would no longer maintain its security guarantee to New Zealand, although the ANZUS treaty structure remained in place.

The Oxford Union debate

One of the concerns of the United States over the ships’ row was that other countries might follow New Zealand’s lead, thereby undermining the Western alliance. David Lange had effectively become the ‘pin-up boy for nuclear disarmament’, and this was demonstrated on 2 March 1985 during the widely televised Oxford Union debate. Lange debated with the right-wing evangelist Jerry Falwell, and his performance in arguing the proposition that ‘nuclear weapons are morally indefensible’ was masterful. The quick-witted David Lange drew thunderous applause with his now-famous – if not entirely original – reply to an American student: ‘hold your breath just for a moment. I can smell the uranium on it as you lean toward me!’ Briefly, New Zealand was at centre stage.

In 1987 Labour passed the New Zealand Nuclear Free Zone, Disarmament, and Arms Control Act. In a largely symbolic response, the United States Congress retaliated with the Broomfield Act, downgrading New Zealand’s status from ally to friend. David Lange stated that if the security alliance was the price New Zealand must pay to remain nuclear-free, ‘it is the price we are prepared to pay’. In 1989, 52% of New Zealanders indicated that they would rather break defence ties than admit nuclear-armed ships. By 1990 even National had signed up to anti-nuclearism.

NZ history is supposed to be politically neutral and accurate. This article is neither. It is clearly written by a supporter of the 1984 Labour Party government and the anti-nuclear laws. The references to "Robert Muldoon" - actually "Sir Robert Muldoon" by then, and the suggestion that Waring withdraw from the National Party caucus after having been "savaged" by Robert Muldoon is false and apparently deliberately malicious.
