An investigation is underway after a man was injured at a gathering of antisocial road users in Waikanae on Friday night

Police were called to Old State Highway One about 11.30pm.

While they were there - ambulance officers told them a man had been struck by a vehicle doing burnouts.

Police says frustratingly, the anti social road users obstructed emergency services from getting to the injured man - and the vehicle believed to be involved fled the scene.

The man was taken to hospital in a moderate condition.

Police say they're working to identify those responsible.
