Cambridge and Ngongotaha have been runaway title contenders and have both beaten each other once this season. The in-form Rotorua club still have three games to play this season, all away from home, including a match against Otumoetai tomorrow afternoon.
Meanwhile, Rotorua United broke their losing streak last weekend with a win over lowly Tauranga City and will be looking for another three points against Melville United in Hamilton tomorrow.
Melville sit in third position on the ladder and will pose a tough assignment for Rich Barter's Rotorua United team.
The relegation spots have already been decided with Tauranga Boys' College and Tauranga City both going down to the WaiBOP Championship next year.
