A man has been charged with dangerous driving causing death following a fatal crash in Ohingaiti.
The motorcyclist who died in the crash on State Highway 1 was James Gregory Nelson, 54, of Paraparaumu.
A police spokeswoman said although a man had been charged in relation to the collision, which happened on Sunday, November 12, they were continuing to seek witnesses.
"Police are particularly interested in any sightings of three motorcycles possibly travelling together southbound on SH1 around the time of the crash. They would have been on the highway between Taupo and Bulls area between 5pm and 6.30pm."
Anyone with information should contact Detective Karl Reyland at Whanganui Police.
"Our thoughts are with James' friends and family at this difficult time," the spokeswoman said.
