David Seymour joined Mike Hosking as acting Prime Minister while Christopher Luxon is in Singapore.

They discussed the big topics coming into this week including the war in Iran and the USA's call for support, and ACT's new immigration policy. 

On the potential of NZ involvement in Iran Seymour told Hosking, "We're not going into a conflict zone, but if there was genuine, cross-partisan support for us to join a coalition of like-minded nations to ensure that trades on the seas can continue, that is in New Zealand's interest.

"We're a trading nation. We need freedom of navigation."
