Prime Minister John Key says New Zealand and the United States have an ongoing agreement that each other's ships do not berth in home ports because of anti-nuclear legislation.
For the first time in 28 years, New Zealand is taking part in the world's largest international maritime exercise, Rim of the Pacific.
The frigate [Te Kaha and tanker Endeavour have berthed at a local Honolulu port, rather than at Pearl Harbour.
However, Mr Key says this has had no impact on the New Zealand Defence Force's involvement in the exercise and they expected not to berth at the military port.
In May, the Prime Minister said he would like the US Coastguard to come to New Zealand shores as it would not breach the law.
