Police and army personnel have continued searching a Linton property to identify any evidence that will help them locate Whitu Hansen.
The search for Mr Hansen, 48, became a homicide investigation on Tuesday.
Detective Senior Sergeant Simon Harrison said the search for the missing Wanganui man is expected to run into the coming week, given the extensive size of both the section and number of buildings on the section.
"I want to thank the community for their patience and understanding with our continued presence at the property. It's crucial to our investigation that we complete a meticulous examination and gather any potential evidence.
"Given the large size of the property and its rural location we received assistance from the New Zealand Army in searching the scene. They finished up searching yesterday and I want to thank them for their support in this investigation," Mr Harrison said.
