Traffic is now flowing at Oteha Valley following this morning's three-vehicle smash.

The crash, involving a concrete mixer and two cars, caused major disruption on Auckland's Northern Motorway this morning.

Traffic heading to the city was down to a crawl after two of three lanes were blocked by the multi-vehicle crash at around 6.30am.

Inspector Jason Greenhalgh said the nose-to-tail crash disrupted the morning commute while the damaged vehicles were being cleared.


No one was injured, he said.
