Aquinas College used a bruising forward-oriented brand of rugby and terrific line speed to dismantle Mount Maunganui in the final of the Western Bay of Plenty First XV tournament.
The two sides, drawn to meet in the opening round of the secondary school Division Two competition in early May, slogged it out in a physical encounter dampened by early rain.
The downpour suited Aquinas' aggressive forward pack, which took the game by the scruff of the neck early and refused to let go.
Aronia Solomon crashed over down the short side after a period of sustained forward pressure to open the scoring, before a clever box kick from halfback Maihi Bidois led to a try from hard-hitting second five-eighth Te Nawe Ngatai.
The side's third try, to rangy lock Dion Collins, stretched the lead to 15-0 at the break.
