The police have warned that there will be long delays on State Highway 1 between Orewa and Wellsford due to heavy holiday traffic.
Inspector David Mongomery said police were asking that travellers avoid the area.
He said people should use State Highway 16 as an alternative route or not travel there at all.
There have not been any major accidents on the road, but the queues are caused by sheer volume of traffic.
