A multi-vehicle crash on a highway connecting to Auckland Airport has been causing major delays.
The NZ Transport Agency said the collision occurred about 6.50am and had blocked two out of the four southbound lanes on the Southwestern Motorway, SH20, on Māngere Bridge.
The lanes had since been cleared but there was congestion back to Waterview Tunnel.
Traffic heading along SH16, Northwestern Motorway, should consider using SH1 to get to Auckland Airport and to head south.
