One person is trapped after a crash between a car and a truck on an Auckland motorway today.

A Fire Service spokesman said emergency services were at the scene of the crash, which occurred just after 1.30pm, and were working to free one person from the wreckage.

He said a truck and car had crashed along the north-bound lanes of the Southern Motorway, near the port exit in Grafton.

It is unclear if any lanes have been closed as a result of the incident.
