A diplomatic cable dated in 2004 reported that senior officials in Helen Clark’s former government viewed New Zealand’s anti-nuclear policy partly as a way to reduce defense obligations after the country’s effective exclusion from the ANZUS security framework. In 2005, U.S. Ambassador Charles Swindells urged Washington to develop strategies for reversing the policy, including examining a possible free-trade agreement. The 1987 law barred nuclear-armed or nuclear-powered vessels from New Zealand waters, and the dispute had curtailed intelligence ties with the United States.
The cables published by WikiLeaks in November 2010 said full intelligence collaboration between the two countries resumed in August 2009, despite both governments keeping the restoration secret. They also reported that New Zealand intelligence monitored the Fijian military before the December 2006 coup and passed information to the United States, although the published cable did not disclose the intelligence itself. New Zealand’s Sunday Star-Times characterized the ambassador’s warning that the country could be excluded from the Five Eyes arrangement as a threat, highlighting how alliance pressure and classified surveillance cooperation intersected with national sovereignty and public accountability.
