What was already a busy day for Christopher Luxon has just become busier. 

A fault with New Zealand’s Defence Force plane has forced the Prime Minister fly commercial to Melbourne for today's ASEAN summit. 

He has a tight schedule to keep to, meeting with eight South-East Asian leaders on the sidelines of the special ASEAN-Australia summit. 

Newstalk ZB Political Reporter Demelza Jackson told Mike Hosking that each meeting is only about ten minutes long, but its more about putting a face on the New Zealand name. 

Tomorrow, she said, is all business, with ANZ’s business breakfast in the morning and a trip to a Fonterra factory in the afternoon.
