Police investigating the disappearance of a Whanganui man suspected slain are trying to track down a new vehicle.
Whetu Teaola Hansen, 48, was last seen on November 24, and was noticed missing by police on December 2.
He was last seen driving his 1980s primer-grey Ford ute toward Palmerston North. His disappearance started out as a missing person investigation at Linton property, but it has since been elevated to a homicide inquiry.
Hansen's ute was found parked at the house on December 5, and police have previously asked for sighting of its movements.
As the investigation at the property begins to wind down, Detective Senior Sergeant Simon Harrison said police were now looking for information on another vehicle, a 1981 Mitsubishi wooden flat deck ute.
''This vehicle has recently come up as part of our inquiries and we believe that it may play an important role in helping us solve this investigation.''
Mr Harrison said a search of Hansen's Whangnui home was carried out on Monday in the hopes of tracking his movements up until his disappearance, and a number of items had been taken for analysis.
The scene examination at the Linton property was in its final stages and was likely to be finished by tomorrow afternoon, he said.
Police want to speak to anyone that saw the Mitsubishi ute in the wider Palmerston North area between November 23 and December 5.
Anyone with information is asked to contact Detective Dave Wilson (06) 213 9595. Information can also be provided anonymously via Crimestoppers on 0800 555 111.
