Fire and Emergency New Zealand crews continued work on the Black Jack Road vegetation fire on the Coromandel peninsula today with three helicopters and four ground crews.

Black Jack Road has been closed all day today with stop/go traffic management supporting access for residents.

“There will be periods of total road closure to allow our firefighters to work safely. We will let everyone know when the road reopens,” Incident Controller Shane Bromley said.

Bromley said this morning that while the fire is under control, it was not yet contained.

“It is hoped the fire will be contained by the end of today.

"While flames aren’t visible to the public, the fire is still smouldering,” Bromley said.

“The western side of the fire is inaccessible to ground crews, so we still have three helicopters working on that side of the fire."

Crews this afternoon have been focusing on dampening down hotspots and the left-hand flank of the fire.

Black Jack Road is still closed with limited access under traffic management.

There have been no evacuations due to the fire which is estimated to be approximately 600m x 600m. A strong southerly wind is blowing smoke from the fire out to sea.

Bromley would like to thank the public for allowing firefighters to work safely through following the traffic restrictions.

At this stage it is not known how the fire started. Fire and Emergency NZ said an investigation will take place to determine the cause.
