Police in South Auckland want to hear from anyone who was at the scene of a crash in which a motorcyclist suffered fatal injuries.
A 47-year-old man suffered critical injuries when his bike collided with a blue vehicle pulling out of Tuakau Rd, in Pukekohe, on Monday, February 22.
He died in hospital four days later.
Counties Manukau road policing manager, Inspector Alison Brand, said police wanted to speak to the occupants of a white vehicle that was immediately behind the motorcyclist when the accident happened about 4pm.
"The motorcycle overtook a white vehicle near the intersection of Tuakau and Bucklands roads, immediately prior to the crash occurring," Ms Brand said.
