The Tauranga students squared off against Element IMF Cadets, who finished at the top of the qualifying series.
At the halfway stage of the title decider Cadets appeared to have one hand on the trophy, after Tauranga Boys' were dismissed for what looked to be a modest 93 runs.
But few of the Tauranga Boys' supporters could have imagined the damage that a foursome of spin bowlers would inflict on the Cadets batting line-up as they were removed for just 58 to give Tauranga Boys College back-to-back T20 titles.
Revenge is certain to be on the agenda for Cadets when they meet the schoolboys in a replay of the March title decider on Saturday.
City Sports Bar Te Puke meet East Bay United, Eves Realty Greerton will be chasing a good start to the competition when they meet BOP Indians, with Mount Maunganui and Central squaring off on the artificial surface.
In round two, a Baywide inter-city derby will take centre stage when Cadets and Central meet on Fergusson four.
