A scrub fire along the Northern Motorway is causing traffic delays in Auckland.
Police said smoke from the fire was slowing traffic at the Puhoi tunnel in Waitemata.
Fire Communications shift manager Megan Ruru said two fire engines were at the scene of the blaze.
The fire started about 11.20am and was along the motorway just north of the tunnel and over an area of about 900 metres.
The motorway was still open to traffic. Motorists were advised to take extra care and avoid the area if possible.
