The NZ Transport Agency says one northbound lane on the Southern Motorway at Takanini is closed due to a fatal crash.
The incident happened just before the Walter Strevens Bridge around 7.30am this morning.
Police requested all northbound motorway lanes close while they investigate.
Traffic is already 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.
