Images have emerged of a two-truck crash that blocked all northbound lanes on State Highway 1 at Pokeno on Auckland's Southern Motorway for a time this afternoon.
The Auckland Rescue Helicopter Trust says the driver of the truck and trailer that rolled suffered multiple injuries and was in a critical condition.
It was decided to take him to Middlemore Hospital by road as this was the faster option, a spokesperson said.
According to NTZA, one northbound lane is now open to traffic.
However, the Pokeno off-ramp is closed due to a separate crash.
NZTA are warning motorists to expect delays in the area.
