The girls' under-16 B team also took silver, in division 2, after a penalty shoot-out with North Harbour White and the boy's under-16 B team won the bronze medal playoff against Hibiscus Coast, 8-2.
Josef Schuler and Shinae Carrington were named in the tournament teams, alongside goalkeeper Bae Fountain, who was named boys' Most Valuable Player.
Club chairman Sam Mano said the success showed the strength in depth of the club, with development starting at under-12 level.
''We don't have the luxury of the big competitions that Auckland do and sometimes we struggle for game time. But we have some very talented kids.
''In Tauranga I think we are quite lucky because a lot of our sports are water-related and a lot of our members in the winter do water polo and in summer tend to do surf lifesaving.''
This week the club's under-14 A boys and girls teams are competing in the first division national championships in Wellington while the under-14 B and development teams are competing in the division two championships at Baywave.
