A short statement issued by the Prime Minister on Wednesday marked the end of an era in New Zealand's defence and foreign relations.
It read, "I am pleased to announce that the USS Sampson, an Arleigh Burke-class destroyer, will attend the Royal New Zealand Navy's international naval review in November. Under New Zealand's nuclear free legislation I am required to be satisfied that any foreign military ship entering New Zealand is not nuclear armed. I have granted this approval after careful consideration of the advice provided by the Ministry of Foreign Affairs and Trade."
That was the essence of it. Those three sentences, or similar ones, were all that New Zealand governments have ever asked the United States to accept as a condition of naval visits since the Labour Party's nuclear-free policy was put into affect in 1985.
Successive US governments have perfectly understood that a statement of that kind was all that would be made but they considered it to be in breach of their policy to "neither confirm nor deny" the presence of a nuclear weapon on particular vessel.
Even now, John Key's statement has been careful not to say simply, "I have been advised the USS Sampson is not nuclear armed." This contrasts with the rest of his announcement, regarding the ship's propulsion. "New Zealand's legislation also does not allow ships which are nuclear propelled into New Zealand," he said, "and the advice I received from officials is that the USS Sampson is not nuclear powered."
