Traffic is banked-up on Auckland’s Upper Harbour Motorway after lanes became blocked by a two-vehicle crash.

NZ Transport Agency Waka Kotahi (NZTA) is warning motorists travelling eastbound of delays on State Highway 18, which connects the North Shore to West Auckland, as a result of the collision.

Police were notified
of the crash near the Tauhinu Rd off-ramp in Greenhithe at around 6.10am. “There are no reports of injury,” a police spokesperson said.

Vehicle movement has been restricted during the morning commute, with traffic cameras near the scene showing heavy congestion on the eastbound lanes.
