Police have located two clues in the search for missing tramper Darren Myers.
Myers, 49, was reported missing after he failed to return home from a hike through the Northern Crossing in the Tararua Ranges on June 1.
Sergeant Tony Matheson said on Saturday a search team found a chocolate bar wrapper wedged in rocks in the headwaters of Arete Stream.
"This is an isolated area and is 600 vertical metres below Arete Bivouac where Darren was last known to be," Matheson said.
"We know he had this brand of chocolate bar with him. The wrapper is in very good condition and has an expiry date of 2020 so we are hopeful it belonged to him."
