Ann Ridley wishes she knew what happened to her son who vanished five days ago.
The Thames woman was holding on to hope that Grant Ridley, 46, would be found after his disappearance on Sunday.
Since Tuesday, police and search and rescue teams have been combing through rugged terrain in and around Waihi.
Today, they scaled back the search.
"I do not know either what is going on," Ms Ridley said.
