NZ Transport Agency said the crash was clear of lanes on the southbound off-ramp to Neilson St, but delays were occurring while emergency services were in attendance.
Motorists were advised to take care with queues and allow extra time.
An earlier truck breakdown on the Southern Motorway has also left traffic "a little heavier-than-usual citybound", NZTA said.
The breakdown between Papakura and Takanini was quickly pushed clear but commuters should allow extra time.
