The six-team second round will begin on Saturday with Te Puke taking on sixth-placed Rangataua at Te Ariki Park.
Rangataua pipped Mount Maunganui to sixth spot despite the Mount defeating Whakarewarewa in a thriller at Blake Park. The hosts opened the scoring from a bomb 40 metres out and added a second touchdown to lead 12-0 after 20 minutes.
Whakarewarewa’s first reply was the try of the game, with winger Cameron Dombroski snatching the ball from a Mount player and scampering 40 metres to dot the ball down.
Whakarewarewa led by two points at the break, before the two sides traded five-pointers in the second spell, with Mount Maunganui having the last say in taking out the close-fought battle 31-28.
Greerton Marist finished second in the preliminary competition after defeating Te Puna 43-12 at home. Rangataua ensured a place in the Premiership title race with a 58-5 win over Marist St Michaels, with Judea taking out their first victory of the season, 34-21 from Ngongotahā.
