New Zealand is sending about 80 Defence Force personnel and three Royal New Zealand Air Force NH90 helicopters to support efforts to fight Australia's bushfires.

The New Zealand Defence Force support will travel in an Australian Defence Force C-17 and New Zealand Defence Force C-130 from Ohakea Airforce Base on a number of flights from Monday to Wednesday.

"This latest NZDF support is being provided in addition to the latest rotation of five NZDF Firefighters deployed to bolster numbers of emergency responders on the ground," Defence Minister Ron Mark said in a statement on Sunday.
