A motorcyclist killed when he was run off the road in the eastern Bay of Plenty last month may have been the victim of another gang, police believe.
Police are treating Don Henry Turei jnr's death as a homicide.
The 38-year-old was hit by a Honda Odyssey while riding his motorbike with his brother to a wedding reception on November 26.
The Odyssey then sped off and was found burned out near the banks of the Raukokore River near Te Kaha, a short distance away.
Detective Inspector Lew Warner said witness accounts and forensic examinations demonstrate the collision was deliberate. The Odyssey had been driven into the rear of Turei's motorcycle and pushed him off, he told RNZ.
