Jacinda Ardern and her Australian counterpart Scott Morrison are meeting in Queenstown for their first face-to-face meetings since early 2020.
The meetings come as relations between the two nations have been strained due to differing polices towards China.
There have also been public spats over Australia deporting New Zealand citizens under its immigration policy.
On Sunday Jacinda Ardern acknowledged the two nations' different approaches, but said Australia was family.
Ardern spoke to Corin Dann.
