Traffic is backed up in both directions at Maramarua, south of Auckland after a handful of cars crashed.

Debris is strewn across the road in front of the Pukeko's Nest Cafe and a white Toyota Prado SUV with a damaged front and a red sedan are blocking the southbound lane.

A woman in a high-visibility vest is directing traffic around the vehicles.

A silver Ford Territory with a damaged bumper is sitting on the other side of the road, facing the wrong way.
