Traffic was backed up after a crash on the Bombay Hills.

A crash on State Highway 1 on the Bombay Hill has caused traffic delays.

The crash initially blocked all lanes heading north near Beaver Rd but the car had now been moved to the side.

Emergency services are the scene where the car has overturned. No one was seriously injured.

The New Zealand Transport Agency had warned all lanes north-bound were blocked, causing traffic to build up.

They advised drivers to delay travel north.
