Firefighters are battling a scrub fire on Auckland's Southwestern Motorway.
Traffic is heavy near the Mahunga Drive southbound off-ramp, which is beside the blaze, and motorists have been asked to take extra care and expect delays.
The motorway is a main route to Auckland Airport.
The Fire Service said fire crews had requested a water tanker to help extinguish the remaining flames.
NZTA tweeted that the Mahunga Dr southbound off-ramp was closed as fire crews continued to fight the fire.
AA Roadwatch advised motorists to expect delays along the Southwestern Motorway with traffic travelling at a slow pace during rush hour.
Video of the fire near Mangere Bridge, which was shared on Twitter by the New Zealand Transport Agency shows thick plumes of smoke.
Five crews are still on site working to fully extinguish the fire.
