Firefighters battle Northland scrub fire

Helicopters and fire crew are still battling a large scrub fire burning through a reserve in Northland.

The blaze broke out in a Titoki reserve on Thursday afternoon and firefighters, helicopters, a bulldozer and a digger were dispatched to the site.

Fire and Emergency says crews resumed fighting the blaze early on Friday morning, with six helicopters now tackling it from overhead and two water tankers brought in.

The fire has grown to cover 30 hectares.

No homes or other buildings were at risk from the blaze, but it had already claimed an extensive section of reserve land.

Crews were forced to abandon efforts at 10pm on Thursday and resumed at first light.

The cause of the blaze was still unknown.

There is currently a total fire ban across the entire Northland region.
