A search effort for two men missing in the Tongariro National Park has found no new clues today and will continue tomorrow.
A beanie was found by one of the search teams yesterday, giving fresh hope of finding the men.
However, Inspector Kevin Taylor said tonight that today's search failed to find anything new.
"We will continue because we can't yet put our hands on our hearts and say we have done all we can. There are still some minor pockets in the search area and we will carry on tomorrow.
"It is incredibly frustrating. Lots and lots of effort has gone into this but we have still been unable to find them."
