Rescuers have reached a hut they had hoped a missing French tramper was saying in, only to find he was not there.
West Coast police and search and rescue volunteers have been looking for 32-year-old Yohan Simon.
The man known as Yoyo was dropped off at the Karamea Bluff on Happy Valley Saddle on Friday 18 October, and was to be collected by a friend the following Monday.
A helicopter today reached a hut in the Little Wanganui area, near Falls Creek where it was hoped Mr Simon may be, but there was no trace of him.
Police now believe he may have walked out of the area and are appealing to members of the public for information as to his whereabouts.
