A scene examination is being conducted at the home of a Christchurch man who has been missing for a week.
On Thursday police appealed for sightings of 49-year-old Michael Craig McGrath, who was last seen the previous Sunday evening at his home in Halswell, where he lives alone.
On Sunday police conducted a scene examination at his home, reiterating that they have concerns for his safety.
Police are seeking sightings of Mr McGrath's 1994 blue Subaru Legacy station wagon last weekend in the Halswell area.
He was thought to be on foot when police first raised concerns about his well-being. The car was at his house.
Mr McGrath is reported to have done a lot of building work in Christchurch.
He is about 180cm tall and is of average build.
