US Secretary of State Hillary Clinton will sign a broad policy agreement when she visits New Zealand next week.
However, Prime Minister John Key says he is not expecting any announcement from Mrs Clinton on military matters.
Mrs Clinton was due to visit in January, but had to postpone that trip after a devastating earthquake in Haiti and will now be in New Zealand from next Thursday to Saturday.
Radio New Zealand's political editor reports while there has been speculation Mrs Clinton might announce a resumption of joint military exercises, that appears unlikely.
In a briefing in Washington before her trip, assistant secretary of State for East Asia and the Pacific Kurt Campbell gave details of what he called the Wellington Declaration.
Mr Campbell said it would cover non-proliferation, politics, climate change and how the two countries could work more closely in the Pacific.
Military ties, however, have not been officially mentioned.
