The previous three finals had all featured Taieri but the side as lost every time and it has been disheartening for the club.
But it got the winning feeling on Sunday, riding on the back of English import Jake Foley to claim the victory.
Taieri won the toss and decided to bat in the twenty20 encounter.

It has also pulled its funding for the tournament making it harder for teams to commit to head to Auckland.
Some teams pulled out of the competition before it started but Taieri was keen and ended up with a convincing victory over North East Valley in the final on Sunday.
Taieri posted a competitive total of 156 for seven wickets, Foley scoring 59 and Marcus Frost making a valuable 27 at the end in a brisk 16 balls.
North East Valley never got going in reply and was dismissed for just 116 from the first ball of the 20th over.
Tom Griffin was the only player to score more than 20, reaching 22, and the side never had any partnership of note.
Taieri bowlers Ben Lockrose and Regan Flaws put the brakes on and Dale Phillips picked up three wickets as the pressure went on.
The national club finals will be in Auckland at the start of April.
