All northbound lanes of Auckland's Southwestern Motorway are closed after four trucks collided leaving at least one person with moderate injuries.
Diversions are currently in place after the crash at the exit to Maioro St.
Motorists are instead getting off the motorway at Hillsborough.
Video of the crash shows a massive backlog of traffic, while police and St John Ambulance are at the scene.
A police spokesperson said police were called to the crash just before 8.30am.
"At this stage, police are aware that at least one person has sustained injuries and are awaiting an assessment of those."
Northbound traffic is currently being diverted off the motorway at the Maioro St off-ramp and back on via the on-ramp.
Police advise motorists to avoid the area if at all possible this morning.
