The NZ Transport Agency says one lane only is now closed northbound on Auckland’s Southern Motorway (State Highway 1) due to an earlier crash at Takanini.
Emergency services are on the scene of the incident between Papakura and Takanini.
One lane has now reopened to traffic, however the second lane will remain closed while Police investigate.
Traffic is heavy in the area, with congestion back to Drury.
Motorists are advised to delay their travel or take alternative routes via Great South Road at Papakura.
