The women's final was a much more one-sided affair, with North Harbour easing away to beat Porirua 79-45.
Women's MVP Anna Lacey had a game-high 19 points for Harbour, who also had Tera Reed (17) and Camece Salmon in double figures.
Salmon was impressive and played hard on both ends, picking up five offensive rebounds on her way to a double-double.
Tauranga and Rotorua finished sixth and seventh respectively in the women's competition, while Rotorua came tenth in the men's division.
The only Tauranga player to make the tournament team was Otumoetai College Year 12 student Kelcy Ballantyne.
