Traffic is backed up on Auckland's busy Southern Motorway at Bombay after a fire broke out in a rubbish truck.
Waka Kotahi NZTA said a southbound lane between Bombay and Pokeno was blocked because of the vehicle fire which broke out before midday.
The agency is warning motorists they will face long delays getting through the area and asking motorists to delay heading south and avoid the area altogether.
In a tweet the agency asked motorists to expect a long trip south and consider getting off at Mill Rd, Bombay and rejoining the highway at Pokeno if they still planned to head south out of the city.
