Police want to speak a driver involved in a four car crash, which has left one person with serious injuries.

Witnesses to the collision at 11.30pm on Friday on State Highway 1, at Karapiro, are also being sought.

Constable Casey Gies says two people were injured, one seriously, and police are yet to speak to one of the drivers following the Friday the 13th crash.

'The outstanding driver is in a white or pearl-coloured late model Honda Integra.

'The vehicle may have its casing missing off one of the wing mirrors as a result of this incident.”

The driver, who is not understood to be at fault at this time, is described as possibly Indian, in his early 30s and was clean cut with a beard, says Casey.

Police believe he may be able to assist with the Serious Crash Unit's investigation.

The driver, or anyone with information which may assist, is asked to contact Constable Casey Gies at Cambridge Police on 07 827 5531.
