The crash occurred at the intersection of Te Puke Highway and Rangiruru Road. The Serious Crash Unit conducted a scene examination after the incident.
Detective Senior Sergeant Natalie Flowerdew-Brown said a homicide investigation has been launched and a 25-year-old man charged. Police are asking anyone with information, or who has CCTV or dashcam footage of a white 2005 Toyota Caldina travelling in the Brown Road area, to come forward.
"Any information, no matter how small, could be crucial for our enquiries," Flowerdew-Brown said.
The injured person remains in hospital in a critical condition.
