Prime Minister Jacinda Ardern says that the New Zealand-Australian relationship remains important, despite tensions surfacing this week. 

It was revealed yesterday that the 26-year-old woman - who Turkish officials are calling a terrorist - held New Zealand and Australian citizenship, but Australia has revoked theirs.

She's now been caught trying to flee Syria with her two children, and will likely end up being sent to New Zealand. 

Talking to media yesterday, Ardern said Australia's abdicated its responsibilities and she's personally made that point to Morrison.

Asked by The Country's Jamie Mackay about her comments, Ardern says that on the basis of the facts, she'd expect others would be annoyed as well.

She says that while this was made public yesterday, this has been an ongoing trans-Tasman issue for several years. 

However, she says that the relationship is "really close", and counterparts know how she felt. 

"I speak to PM Morrison probably on a weekly if not fortnightly basis. So there are no surprises here in our relationship. They know exactly how we feel about this issue."
