Hawke's Bay Fish & Game Regional Manager Pete McIntosh has spoken to police, after his company-owned vehicle was found overturned on Kahuranaki Rd late on Friday afternoon.
By the time emergency services arrived at 4.30pm they found the badly crushed silver ute on its roof but were unable to locate a driver.
Mr McIntosh voluntarily went to Hastings Police Station for questioning yesterday afternoon.
Police Senior Constable Tim Rowe said: "He claims he had concussion and can't remember the accident or anything afterwards."
Witnesses who appeared soon after the crash allegedly saw a man with an injury to his head crawl out of the passenger door, before getting into another vehicle and driving off. Authorities still hoped to track down the second vehicle and its driver.
Police believe the ute lost control on a sweeping left-hand bend, crossed the centreline, hit a bank on the right side of the road and rolled, before crashing into a tree and landing upside down. On Sunday, Mr McIntosh confirmed to Hawke's Bay Today that the ute belonged to Fish & Game but declined to comment further.
Numerous attempts were made to contact him yesterday but without avail.
Mr Rowe said Mr McIntosh was likely to face charges relating to the incident.
The vehicle has been impounded for forensic examination.
