The government last month tabled a bill that would commit New Zealand to carbon neutrality by 2050.
Speaking after a meeting with his counterpart Jacinda Ardern in Wellington on Wednesday, Charlot Salwai said addressing the climate crisis is of great importance to the Pacific.
"It is a very important issue and we are so happy and welcome that the New Zealand prime minister is very supportive to this concern that has been raised by the Pacific Island countries because we are really affected.
"Smaller islands like Tuvalu and others [particularly] but Vanuatu as well is also affected by this climate change."
Charlot Salwai side-stepped a question on whether the return of a pro-fossil fuel government in Australia was disappointing.
