Two cars have collided on the Northwestern Motorway in Auckland.
Two people have been taken to Waitakere Hospital in a moderate condition, a St John ambulance spokesman said.
The crash happened shortly after 1.30pm today on the westbound lanes near the Point Chevalier exit.
The cars involved were at one point blocking a motorway lane but both lanes were now clear, said an NZTA spokeswoman.
Police have cleared the lane but remained on site.
Traffic was only slightly disrupted.
"There is about a 200m tailback, but it's moving," said NZTA spokeswoman Sarah Azam.
