Police have paused their search for Michael MacGregor, who went missing in the Mount Holdsworth area 10 days ago, and will use cadaver dogs to look for him in the next few weeks.
MacGregor failed to return from a walk in the Mount Holdsworth area near Masterton last Monday, and search teams have been scouring the mountain in poor weather conditions.
Police Search and Rescue, Land Search and Rescue volunteers and a specialist canyoning search and rescue team were deployed as ground search teams searched near Atiwhakatu Stream.
MacGregor was last seen at the Rocky Lookout at 12.20pm on Monday, wearing shorts and a hoodie.
