Kaitaia Police Detective Sergeant Trevor Beatson said inquiries were continuing and both were expected to face further charges.
Far North area prevention manager Senior Sergeant Chris McLellan said the teenager was believed to have been involved in a spate of offending in the Takahue, Victoria Valley and Honeymoon Valley areas.
Both were to appear in the Kaitaia District Court on Wednesday.
Mr Beatson said police had also recovered a quantity of property that was believed to have been stolen from boats at Unahi.
Anyone who had lost property in that location was asked to contact Constable Jared Vivian on (09) 408-6500.
Meanwhile inquiries prompted by a spate of burglaries in Kaitaia's North Rd area resulted in two arrests on Tuesday. An 18-year-old man was charged with cultivating cannabis, and a second man, from another address, with one count of burglary.
He was remanded in custody later in the day, and is expected to face further charges.
Mr McLellan said police were still looking for the property, including expensive dive gear, from those burglaries, which they believed had been fenced.
Police expressed their gratitude for the public support they had received.
"It was information from the community that led to the arrest in Kaitaia," Mr McLellan said.
"That arrest and the two at Te Rore Rd were very good wins for Kaitaia, and without public help our job would have been much harder."
Mr Beatson said the Te Rore Rd incident had been a classic case of the community looking after the community, neighbour looking after neighbour.
