Police are hunting for a ute and its driver they believe witnessed a hit and run last month that left a man fighting for his life.
Police were called to State Highway 2 between North St and Ahikōuka Rd in Greytown around 7am on June 24.
Mystery previously surrounded how the victim, William Newton, came to be injured, and police put out a public plea for help to understand his movements before he was found.
They have since determined Newton was walking next to the northbound lane on SH2 when he was struck by the vehicle, which quickly left the scene.
Police are now searching for the driver of a 2016-2020 Mitsubishi Triton utility fitted with a flat deck and front bullbar with side protection.
