One person is trapped after a "truck versus truck" accident in Auckland west of Manurewa.
Police confirmed one vehicle was a rubbish truck, but they weren't aware of injuries at this stage.
Auckland Transport said in a post to Twitter the crash had delayed traffic.
They reported southbound lanes were closed, and northbound lanes remain open on Roscommon Rd.
A fire communications spokeswoman confirmed the trapped person had been freed.
The person had lacerations, and they were treated by ambulance at the scene.
