He said Rapatini was aware that he is wanted by the police. It was possible that he could be armed.
The 19-year-old, who is also known as "Rusty", is believed to have Waikato contacts in Mangakino and Te Aroha.
Rapatini was in the news as a 9-year-old in 2001 when he went missing while walking up 1042m Mt Titiraupenga in the 78,000ha Pureora Forest Park, sparking a major search.
He spent two nights in the bush before he was found walking on a track by a search and rescue team.
