Thames bushfire fought from land and air

fire service

Fire crews working on a Coromandel bushfire have some tough terrain to battle as well as a forecast increase in wind.

The fire started on Moanataiari Creek Rd near Thames on Friday afternoon, and is now under control.

Department of Conservation operations manager for Coromandel and Whitianga Dale Tawa says two helicopters with monsoon buckets and three ground crews of five will be sent in on Saturday to continue the work.

A predicted northwest wind later today is a "concern" and will mean the teams will focus on the southern flank of the two-hectare fire to stop the spread.

But before the ground teams head in, they'll need to be ready for the job at hand, Mr Tawa says.

"It's really steep terrain with a few hidden mine shafts in the area, so the teams need to be fully briefed and prepared."

It is not clear what caused the fire.
