They managed a 2-2 draw which has put them one point outside the drop zone.
But Melville have already played all 22 matches this season and are far from safe.
Matamata are only one point behind them with two games left to play, both against Cambridge, and they have better points differential.
A draw in either game would almost certainly get Matamata out of relegation and see Melville drop down.
Tauranga Boys' College are the other club being relegated, after finishing bottom, while Rotorua United and Katikati are the two clubs coming up next season.
