Air New Zealand's Chair says the airline's done its best to help with the Defence Force plane's failure.  

The Prime Minister's business delegation flight broke down yesterday in Papua New Guinea, en route to Japan. 

Finance Minister Nicola Willis told Heather du Plessis-Allan “We’ve got a defence capability review under way – that includes being able to quickly get to the Pacific and around the world to help out after disasters.” 

Willis said “That’s likely to include a plane capability.”
