Motorists in Auckland faced heavy delays after an alarming crash on Monday afternoon.
Police were notified of a crash near the Khyber Pass Road off-ramp shortly after 1:30pm today.
Fire and Emergency NZ said they freed two people, one from each vehicle, who were trapped under a tanker truck.
One person has been taken to hospital with moderate injuries.
The New Zealand Transport Agency (NZTA) says all lanes are now open near the Khyber Pass off-ramp on the Southern Motorway.
They have warned this incident will cause additional delays for any traffic heading towards the North Shore via the Auckland Harbour Bridge.
"Expect delays as congestion eases through the area."
Aucklanders have been facing horrific traffic after two truck crashes on the Harbour Bridge on Friday reduced half its lanes.
There are currently only two lanes on the Harbour Bridge operating on each side.
NZTA will be shutting the southbound lanes of the bridge from 9pm Tuesday until 5am Wednesday as it works to open temporary extra lanes each way.
Brett Gliddon, NZTA general manager transport services, said on Saturday permanent repairs to the bridge could still be more than five weeks away.
