According to Google Maps, traffic is backed for 4.5km approaching the airport, with the tail of traffic back to the Southwestern Motorway.
“Delay your journey or use SH20B (Puhinui Rd) to get to the airport until further notice,” the agency wrote.
A police spokesperson said the fire was reported at 5.53am.
It’s the second day in a row that flights in and out of Auckland Airport have been cancelled and delayed due to fog.
More than 100 flights were cancelled or delayed on Monday as thick fog hampered airport operations.
Fog restrictions were lifted after midnight, but just before 5 this morning the airport said restrictions had been put back in place.
It said passengers should check the Auckland Airport website or app for the latest flight arrival and departure information.
Auckland Transport said ferries, too, were affected by the fog. Downtown and Beach Haven/Hobsonville Point are delayed up to 15 minutes.
On Monday morning heavy fog delayed or cancelled 89 domestic flights in and out of the city, while a further 14 flights were cancelled last night. There were also widespread ferry cancellations and delays.
MetService forecaster Lewis Ferris said on Monday morning there was a mixing pot of bad ingredients that was causing the fog to hang around.
He said MetService expected visibility would increase during the morning as the sun began to heat up the ground ― a prediction that came to pass with fog restrictions lifted shortly after noon on Monday.
Ferris said the sun’s low angle due to the winter solstice, high clouds blocking the sun, and the lack of wind made for the perfect foggy conditions.
