Cameron Neal top scored with 47 as Greerton made 150-7 against BOP Indians and then bowled the Rotorua side out for 74.
In an intercity battle, Mount Maunganui chased down Rotorua Central's 135 for the loss of five wickets.
No player made a more spectacular entrance into the first day of the Baywide T20 competition than Te Puke bowler Sean Gibson.
After taking three wickets in the early afternoon game, Gibson went ballistic against BOP Indians, taking six wickets for just 4 runs.
Te Puke batted first and posted a solid 176/6, with Mitch McCann top scoring for the second time in the day with an unbeaten 77.
The Indian team challenge was swept aside when they were removed for 60, with Jeremy Bates taking three for six to add to the six-wicket bag by Gibson.
Tauranga Boys' College upset Mount Maunganui after they posted 120-6. Gareth Wallace top scored with a solid 43 with Alex Oakley chipping in with a very handy 34 runs.
Tauranga Boys' mentor Mark Orchard was the star of the show, taking two wickets and grabbing four catches in the field. Greerton joined Te Puke in posting two wins, when they easily got past East Bay United after the Eastern Bay side were removed for 96. Cadets defended a relatively modest 115-7 against Central when they restricted the opposition to 102/9.
