Smoke is billowing from a car on fire on Auckland's Northern Motorway, just after the Silverdale Interchange.
Fire and Emergency New Zealand told 1 NEWS they have one crew at the scene where the car is well-ablaze.
No one is injured, and the owner of the car was the one who called emergency services, they said.
NZTA advised motorists to take extra care in the area where there is reduced visibility. There are delays both directions.
