Two people have been seriously injured in a crash in Horowhenua this afternoon.
Motorists north of the capital are advised to expect delays after a crash closed State Highway 1 near the Ōhau River Bridge.
Police said the crash had involved a motorcycle and a truck, occurring just south of the Ohau Bridge about 12.45pm.
By 2pm the patients had been transported from the area via helicopter, and the Serious Crash Unit was on the way.
Waka Kotahi NZTA asked motorists to avoid the area or delay travel if possible, as the road would remain closed for a few hours as the SCU completed their investigation. There were no diversions in place.
