A search effort for two men missing in the Tongariro National Park has uncovered a clue during its seventh day - a beanie.

One hundred and one people, most of whom are volunteers, scoured the dense bush today to look for the men who fled into the forest to escape a police pursuit last Saturday and got lost.

Police say searchers came from as far afield as Auckland and Wellington to help. Most of them are expected to continue tomorrow.

The Police National Dive Squad also thoroughly searched the Mangoatawai Stream and the area which joins the Tongariro River.

Inspector Tony Jeurissen said the men were still missing but searchers were determined to find them and police were making further plans based on today's search.

"As a result of everyone's relentless focus, we continue to find items of interest."

One such item - a beanie - was found today, providing another clue for the search management team.

"These small developments keep everyone going each day," said Jeurissen.

"With the continued dedication from all the volunteers, we will bring these men home to their whanau."

Police and LandSAR teams will continue with the search tomorrow.

"I am so grateful for the enthusiasm from so many people all week and for the ongoing support from Ngati Tuwharetoa."
