Another matter of importance, and perhaps one which enabled Labour to survive public dissatisfaction, was the nuclear issue. In the previous parliamentary term, New Zealand had adopted legislation which prevented nuclear weapons or nuclear-powered ships entering New Zealand, a move which provoked an angry reaction from New Zealand's allies in the ANZUS treaty. The National Party intended to revoke the ban, but the New Zealand public were supportive of it. Labour's support for the ban is often considered to be an important factor in the party's re-election.
