An inquiry into the death of a Tribesmen motorcycle gang member has been upgraded to a homicide investigation.
Police today said witness accounts and forensic examinations of the scene and motorcycle showed the crash that killed Don Henry Turei Junior was a deliberate act.
"We believe Mr Turei was purposefully hit by a white Honda Odyssey-type van, which immediately left the scene of the crash," Detective Inspector Lew Warner said.
"We are continuing to seek information and sightings of a white Honda Odyssey in the Raukokere area on 25-26 November.
"The burnt out vehicle was found near the banks of the Raukokore River not far from where Mr Turei died. We know someone out there will have information on who may have committed this crime."
