Firefighters continue to battle a scrub fire that cut off carloads of day trippers in two isolated Coromandel bays yesterday on Saturday afternoon.

Three helicopters and four ground crews continue work on the Black Jack Road, Kūaotunu, fire today, Incident Controller Shane Bromley said.

“Black Jack Road will be 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.”

Bromley said 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.

It is not known how the fire started at this stage. An investigation will take place to determine the cause.

Daytrippers feared getting trapped

Tarah Spyve said she could not drive back along Black Jack Rd because of the fire. She later said firefighters began allowing cars through five at a time about 8.30pm.

While Spyve was trapped, she said there was no shop to buy food from.

A local allowed the strandees into their home to fill up their water bottles, she said.
