Christopher Luxon is on the ground in Japan, but his business delegation won't be touching down for another day.
The Prime Minister's plane has broken down yet again, this time while refuelling in Papua New Guinea.
Luxon's been forced to fly commercial to Tokyo, while the business leaders, officials and others in his delegation are travelling to Brisbane and then on to Japan today.
ZB political editor Jason Walls says Luxon abruptly disappeared from the airport, leaving his delegation confused about what was happening.
"The Prime Minister leaving took everybody by surprise, I saw his face as he was leaving in the motorcade... he was not happy."
