A man first on the scene of Northland's latest fatal car crash acted with "intelligence and urgency'' and police have praised his bravery.
Last Friday a southbound vehicle is believed to have crossed the centre line and collided with a vehicle, containing an off-duty police officer and partner, travelling in the opposite direction near the Towai Tavern on State Highway 1.
A third vehicle, also northbound, was involved too, and the couple in the car suffered moderate injuries.
The driver and a dog in the southbound Subaru Justy vehicle died at the scene. Police have not named her.
But it was the actions of an anonymous driver on the scene first that have impressed emergency service workers.
