Motorway woes continue with a car fire on SH1 not far from where a container truck has rolled, spilling tonnes of carpet glue across a South Auckland highway on-ramp.

Waka Kotahi NZ Transport Agency confirmed at 11.20am a car fire near Redoubt Rd on-ramp has left two southbound lanes blocked on State Highway 1.

Traffic has come to a stop while vehicle burns fiercely at the side of the road and plumes of black smoke billow across the motorway.

The fire comes as emergency services are already busy attempting to block the drains at the motorway entrance to redirect a large glue spill.

Fire and Emergency New Zealand received a call at 7.56am about a truck rolling and spilling 22 tonnes of carpet glue across Cavendish Drive, near State Highway 20.

The container at the rear of the truck could be seen flipped on its side with its wheels in the air as glue oozed on to the road.

At least a dozen people were responding to the scene, including several road workers in high-vis and police.

Police confirmed there were no injuries.
