Nigel Peterson was last seen in on November 17 in CCTV footage at the Hemo Gorge roundabout in Rotorua.
Today police have announced they will resume the search for the 33-year-old autistic man after gaining new information from a behavioural science profile.
"This new information regarding Nigel's possible behaviour around the time he went missing has given Rotorua Police a better understanding of his potential movements and areas he may have gone," said Constable John Fredericksen.
"As a result, police, family members, and LandSar personnel will spend the coming week planning.
"Then on the 11th, 12th and 13th of May teams will search both new and already covered areas, in the hope of finding some evidence to indicate what happened to Nigel."
