Boys' High coach Warren Litchfield was pleased his team did what they talked about before the game, adding he was happy how his young team stayed composed in defence.
"We defended really well and that's what we talked about, being strong on defence," he said. "We had two 14-year-old boys as our full backs today."
Maungakaramea pulled their goal keeper with 10 minutes to go, allowing another attacking player on the field to try to put pressure on Boys' High.
However, with no keeper, and a fast attacking break threatening, Maungakaramea committed a deliberate foul in their defensive circle, giving Boys' High a penalty stroke and chance to secure the match. Anthony Carter-Bell stepped up to take the stroke against a Maungakaramea field player wearing a helmet, and calmly slotted the ball in the right-hand net.
Litchfield was relieved his team could win the intense final after they took out the round robin title and mentioned they would "go and celebrate with lemonades".
