Takapuna made a solid start to their target and had reached 40 without loss, before the introduction of Mount skipper Dale Swan, who dramatically changed the Takapuna innings with a stunning hattrick. But 77 from opener Max O'Dowd helped Takapuna get home with a wicket to spare with just four balls remaining.
Swan was rewarded for plenty of success with the ball over the four matches with the Bowler of the Tournament Award.
Mount Maunganui clinched the playoff for third and fourth with a clinical display on Saturday.
Bowling first against United Central, the Mount bowlers removed their opponents for 155. Led by a masterful 92 not out from Bay of Plenty captain Peter Drysdale, Mount Maunganui got home with five wickets to spare.
Drysdale's sterling innings came from just 66 balls and included 10 fours and three sixes. He was the only Mount batsman to pass 50 in the tournament.
