Marcel Collett and Taylor Bettelheim strode to the wicket full of purpose and Tauranga Boys' were well in control when Collett was caught and bowled by Louie Robinson for 44.
The arrival of Ben Pomare, after Tauranga Boys' lost their second wicket with 116 runs on the board produced a winning 97-run partnership between Bettelheim and the Tauranga Boys' keeper.
Bettelheim was in sublime touch, as he carried his bat to 105 not out at a strike rate of 84.68. Bettelheim finished the ND competition as the tournament's leading run scorer, with 215 runs at an outstanding average of 71.67. He scored another century against St Peter's School.
Both Western Bay schools started the tournament with wins, with Tauranga Boys' easily defeating St Peter's School from Cambridge and Aquinas accounting for Whangarei Boys' High School.
There were mixed fortunes on day two and three. Tauranga Boys' got past Hamilton Boys' second 11 and Aquinas lost to St Paul's Collegiate on day two with Tauranga Boys' beaten by arch rivals Hamilton Boys' First XI and Aquinas accounting for St John's College by eight wickets on day three.
