Police searching for missing teenager Luke Cochrane in the Coromandel have cordoned off a street after finding a hat believed to be his.
Inspector John Kelly said police were "quite positive" the cap that has been found is the one owned by Luke.
Kelly said the street was being cordoned off so that searchers could scour the area more thoroughly.
The dive squad would also move around to that area and concentrate their efforts on the waterway which surrounded Aquila Drive.
A police officer found the cap while carrying out routine inquiries.
Police are believed to be searching a property just 200m from where he went missing.
Aquila Drive in Whitianga is under police guard and a neighbour understands the item may have been found at a property there after hearing police call out to the property owners.
The scene is 200m from the Whitianga Fire Station, where Cochrane had been at a party on Saturday night.
Cochrane is believed to have left the party on foot 10.30pm and has not been seen since.
Friends of Cochrane's are gathering at the cordon, consoling each other.
Divers, who are also being assisted by Hot Water Beach Surf Lifesaving crews, endured challenging conditions as heavy rain continued to batter the town.
Earlier in the week, a large section of the waterway was inspected by boat with searchers using sonar equipment.
However, the stretch opposite the station was shallower and thick with weeds, requiring the dive squad to manually check the bottom.
If the area doesn't uncover anything of interest, they will then move to an area across the road, occupied by homes and moored boats.
Andre Grobbelaar, a former police officer of 30 years, said the fact that Cochrane's phone was active for an hour after he was last seen was interesting and it would give searchers a good radius to begin their search with.
Grobbelaar, who had been involved in many search and rescues during his time with police, thinks Cochrane may have gone further than just across the road.
When asked about the mood in the community, he said there was overwhelming sympathy for the Cochrane family and all hoped that they could get some closure by finding Luke.
"They're all just saying that they hope they find him for the sake of the family but there's no concerns that there's anything sinister. They're all just concerned that they find him."
It's day four of the search for the 19-year-old, which has today been scaled down from up to 30 LandSar searchers to about 15.
