Wellington Police have re-opened a missing person case from 2008 after receiving a new lead.
Operation Dustin is a homicide investigation following a missing person report in 2008 for 68-year-old New Zealander Do Trieu.
Trieu was last seen on August 21, 2008 and was reported missing by his daughter about three weeks later.
He is believed to have been killed around the time of his disappearance, and Police are now seeking Trieu's body and establishing who was responsible for his death.
Detective Senior Sergeant Warwick McKee, head of the investigation, says the case was re-opened as a homicide investigation after receiving new information.
