One person is in a critical condition after the vehicle they were driving collided with a motorway barrier and rolled into a residential property near Ōtara in Auckland.
The crash happened just before 4am as the vehicle was heading north on the Southern Motorway.
Two people in the vehicle were taken to hospital.
One lane has been closed north of the Te Irirangi Drive on-ramp while the crash scene is examined and cleared.
NZTA says there are long delays heading north between Drury and Papatoetoe, and advises motorists to consider alternative routes.
