Police are appealing to the public to help with a fatal motorbike crash early today.
A man, in his early 20s, died when he fell from his Husqvarna motorbike on State Highway 1 near Kauri, north of Whangarei.
Senior Constable Warren Bunn, also part of the serious crash investigation team, said it then appeared a motorbike rider on a Harley Davidson had struck the man while he was lying in the middle of the road shortly after 4am.
The Harley Davidson rider stopped a short distance away and rang for police help. Other motorists also stopped and parked with their hazard lights on. The state highway was blocked off and traffic diverted through Saleyards Rd and Vinegar Hill Rd until just after midday.
Police are unsure how long the man had been lying on the road or whether he had been struck by another vehicle causing him to fall from his bike.
