Mount captain Kruzzyn Heriman's impact on the match is difficult to judge. He was his team's outstanding player and scored a wonderful individual try, but also accounted for two of his side's three yellow cards and was a spectator when Otumoetai scored its final try to put the match away.
Earlier Aidan Blair scored a double as part of a dominant Otumoetai forward pack that supplied their backs with plenty of quality ball.
The five-tries-to-three margin was a fair result, Mount first five-eighth Xavier Kaweroa showing enough silky touches to suggest he would be a handful with a steady diet of front-foot ball. The results mean both Aquinas College and Bethlehem College will host semifinals. Te Puke High School 2nd XV beat their Otumoetai counterparts 23-21 in the day's other match.
