Traffic has built up on Auckland's southern motorway following a crash near the Khyber Pass off ramp.
Police and emergency services were called to the crash on the northbound lanes at about 1.30pm.
One person sustained moderate injuries.
Three of the northbound lanes were blocked for about an hour after the crash, causing heavy congestion, but have now been reopened.
Police and NZTA are advising motorists to avoid the area and expect delays while congestion eases.
Auckland traffic is already being impeded by the closure of Harbour Bridge lanes in both directions following last week's truck crash.
