Bay of Plenty police district field crime manager Detective Inspector Mark Loper said the 15-year-old would appear in Youth Court today.
It was likely more serious charges would be laid.
Search warrants were executed at three Rotorua properties this morning, and it was likely more people would be arrested and additional charges laid as the investigation progressed, Mr Loper said.
The investigation team located further items of interest overnight in relation to the homicide, including property belonging to the victim.
The police dive squad, which had been at Kuirau Park, would now focus on Utuhina Stream.
Police had informed Mr Skorek's next of kin overseas of his death.
