Gisborne Intermediate hosted the tournament and entered three teams — Hawks, Stallions and Leopards.
Deputy principal Brendon Hart said the 36 students in the three teams had trained together as a squad.
The Leopards were named only the day before the event, so their success reflected the hard work put in by the whole squad.
In their semifinal, Leopards had beaten Heretaunga Intermediate 20-5 after being behind in the game. Taupo beat the much-fancied Mt Maunganui Intermediate team in the other semifinal.
Hart said those taking part played the game in good spirit and were great ambassadors for their community.
The tournament emphasis was on players having fun and achieving their results through skill and fair play.
He thanked the Poverty Bay Rugby Football Union and Poverty Bay Rugby Referees Association for their help, and the families who billeted visiting team members.
