State Highway 1 in Kaipara is now open for motorists, after an earlier crash blocked the highway just north of Auckland’s Te Hana.
The crash between two vehicles was reported at around 11.40am and initially blocked both lanes of SH1 at Topuni.
A police spokesperson said no one had appeared to have suffered any serious injuries.
Stop/go traffic management was put in place and the highway was fully reopened at 1.20pm.
The highway is the main road between Auckland and Whangārei.
