However, Otumoetai and Melville, who have the bye this weekend, also have one game left against Tauranga Old Blues and Taupo respectively.
The bottom two sides will face the drop.
The Rotorua United match kicks off at 2.45pm tomorrow at Neil Hunt Park.
Meanwhile, in the other matches this weekend, Tauranga City host Waikato Unicol, Matamata host Taupo and Whakatane host Cambridge.
Ngongotaha, who sit in fourth spot, have the bye this weekend but could finish as high as third if they win their remaining two games.
Ngongotaha have had a good season this year, looking likely to challenge for the title midway through the season.
AFC Fury (Tauranga) also have a bye this weekend.
