Papamoa now face games against Ngongotaha, Cambridge and Unicol, three heavyweights in the league, which will be true tests of their title credentials.
In other games, Ngongotaha dispatched Tauranga Old Blues 4-1 at Stembridge Rd thanks to doubles from Luke Barker and Josh O'Sullivan.
Ngongotaha are now five points behind Cambridge with a game in hand.
Meanwhile, Unicol comfortably dealt with visitors Tauranga City United.
Unicol's 3-0 victory maintained their record as the only unbeaten team left in the Premiership, but the margin should have been greater. Goals from Lee Warin, Max Hall and Nick Broome secured victory.
Otumoetai backed up from their near miss last week in the ASB Chatham Cup with a 5-1 win at Tauranga Boys' College.
Melville United and Waikato Stud Matamata Swifts fought out a goalless draw at Gower Park to each ensure a top-six spot for another week.
In the WaiBOP Championship, the shock of the day came at Galloway Park where leaders Claudelands Rovers had their first loss, going down 1-0 to second-placed Cambridge reserves.
Claudelands have looked the league's class act but the determined visitors snatched a big win.
