A crash involving two trucks on the Pacific Highway north of Bulahdelah has claimed the life of one of the drivers.

Police say two B-Doubles were travelling one behind the other in the northbound lanes about 4 kilometres south of Nabiac at about 11.50pm on Thursday, when the front truck left the road and tipped over.

The rig travelling behind crashed into the wreckage.

The driver of the front truck, which was carrying garbage, died at the scene.

The other driver was freed by NSW Fire & Rescue and the VRA and airlifted to the John Hunter Hospital in a serious but stable condition with head, pelvic and leg injuries.

A contra flow is now in place as crews continue cleaning up rubbish and the wreckage of both trucks which has been strewn across all four lanes of the highway.
