Police are seeking witnesses after a Mercedes Benz with the registration "SOBADD" crashed at "high speed" on an Auckland motorway off-ramp this weekend.

The white 2011 Mercedes Benz E63 drove west at high speed on the Northwestern Motorway between the Lincoln Rd on-ramp and Hobsonville Rd off-ramp on Saturday night.

Last night a white 2011 Mercedes Benz E63 was driving northwest at high speed on State Highway 16 between the Lincoln Rd on-ramp and Hobsonville Rd off-ramp.

It's understood the car was weaving in and out of traffic while driving at an "erratic high speed".

After taking the Hobsonville Rd off-ramp the Mercedes Benz crashed into the back of a white sedan before spinning 360 degrees and colliding with traffic.

A photo provided by police shows the rear wheel of the car came off.

The driver and passengers then allegedly ran from the scene, making their way down Hobsonville Rd towards Westgate Shopping Centre.

Police say the driver of the sedan is "extremely fortunate" they were not injured because of the speed of the collision.

However, damage to the car was extensive.

The driver wasn't found but police say they are following good lines of inquiry.
