Two people have been rushed to hospital with moderate injuries after a crash on Auckland's Southern Motorway.

Several cars were involved in the crash on the Lambie Drive onramp to the Southwestern Motorway in Manukau.

The crash blocked the left lane of the motorway, but lanes are now clear.

Motorists are being warned to expect delays.


Traffic was also being held up on the Northern Motorway after a truck lost its load on the Silverdale onramp.

The right lane is blocked.
