Fire and Emergency NZ is looking into cutting jobs in a bid to save $50 million a year.

It says it's in a tightening financial bind, and a significant restructure is on the cards - with consultation documents set to be sent to staff by next week.

NZ Firefighters Union national secretary Wattie Watson says Fire and Emergency has already cut a recruit course set to take place in January.

"We've got some real worries there - the recruit course that was being cancelled next year in January, that actually impacts on the normal recruiting."
