Daniel Troy Leslie, 31, was killed after the car in which he was a passenger struck a power pole on the corner of State Highway 2 and Makirikiri Rd.
Detective Sergeant Shane Brown, of the Tararua CIB, said investigations were continuing.
"We are in the process of interviewing the man and woman who were in the vehicle. We are also awaiting forensic test results and the Serious Crash Unit report - both of which will take some time to complete and then review before we can lay any charges."
