A search operation is continuing in Tongariro National Park, after two men went missing nearly a week ago.
Police staff and the Police National Dive Squad, LandSAR teams and a rescue helicopter have joined the search.
The sixth day of the search ended on Friday night with no further items of interest found.
A helicopter has been used to capture aerial images of the area, including some of the dense bush searchers are dealing with. The dive squad is set to join the search again on Saturday.
Inspector Tony Jeurissen says further planning has been carried out, in preparation for another extensive search.
"Unfortunately, they have still not been found, but today's work has identified further areas of interest," he said. "For the seventh day, more LandSAR volunteers will be arriving, including returned searchers and those who are new to this operation."
