Police received a call about the boy getting into trouble near the Top 10 Holiday Park on Beach Rd at about at about 12.40pm on Friday.

He had been part of a group swimming in the area. Residents understood he was a boy of about 17.

Search efforts have been underway since Friday afternoon.

"Today's search will once again be assisted by Waihī Beach Lifeguards using inflatable rescue boats and jet skis," police said.

A parent at Melville High School, who did not want to be named, said her son's friends were present when the drama took place and said the missing student had been part of a geography class outing.


"They had done their class work and were all having a swim before heading back to Hamilton," she told the Herald.

"The young lad got caught by a rip. A teacher tried desperately to save him."

She said the incident had really affected students.

"I don't think we ever expect to send our children on a school trip and they never come back," she said.

Parents and friends of the Melville school community shared their prayers and support underneath the school's Facebook post.
