A driver is in a critical condition after their car crashed into a barrier and rolled into a residential property off Auckland's Southern Motorway near Otara this morning.
The passenger was also taken to hospital after crash at 4am.
It was one of two crashes earlier causing congestion on the city's motorways. One northbound lane north of the Te Irirangi Drive on-ramp was closed as the serious crash unit investigated.
No one was injured in the second crash, on southbound lanes of SH20.
Both lanes have now re-opened, with State Highway 1 back to normal by 9am.
