Shortly after the crash, police told the Herald Rapaea was "of no fixed abode",
Police used a drone to find anyone from the car in the nearby toetoe and maize bushes to make sure the driver had not crawled into bushes and died.
Sergeant Cory Ubels, officer in charge of the Serious Crash Unit in Hawke's Bay, hoped viewers of the Police Ten 7 segment will be able to offer information that would help identify the driver.
"This has been a long and complex investigation for which Mr Rapaea's grieving whanau need answers," he said.
"I'm hoping that with the passage of time, people who have information about the crash and the driver's identity, will be prompted to come forward and tell us what they know."
Ubels said evidence suggested two vehicles were travelling in convoy.
The segment will screen at 7.30pm on TV2.
