Police investigating the death of 21-year-old farm worker Eion Gebert near Opotiki believe there are likely witnesses to the fatal crash who haven't yet come forward and they are urging them to do so.
They also want to trace the passenger of a vehicle involved in the crash who left
the scene before police arrived.
Mr Gebert was on his way to work on a motorbike at approximately 5am on Saturday, December 1, when he was struck by car travelling in the opposite direction.
A witness has reported that the car overtook a tow truck and three others cars immediately prior to the crash but only the truck driver stopped at the scene and spoke with police.
The driver of the car involved in the crash also spoke with police at the scene. However his passenger is reported to have left in a silver station wagon. Although police believe they know the identity of the passenger they have been unable to locate him.
