Traffic is heavy on Auckland's motorways this morning, with surface flooding following an early morning dump of rain and at least three crashes around the city.
The NZ Transport Agency warned airport-bound drivers to allow extra time with two separate crashes on the Southwestern Motorway heading south.
A crash that happened about 6.45am blocked the right lane on Mangere Bridge, with drivers warned to merge carefully in the wet conditions.
Further south a crash just before 6.30am blocked the left lane southbound after Lambie Drive.
Both crashes have been cleared but traffic is heavy from Hillsborough to Onehunga Wharf.
