Whakarewarewa lie a point behind in the contentious fourth spot, but Greerton Marist are just three points further back on 46 points and hitting top form at the right time of the season.
Both clubs have key home ground advantage on Saturday.
Whakarewarewa host Te Puke, while Greerton Marist welcome near neighbours Rangataua at Waipuna Park, Welcome Bay, with Greerton Park still not available after recent flooding.
Te Puke's head coach Craig Jeffries knows the pride of Rotorua are always a huge challenge.
"We know what they're like out there. When we played Whaka last time, they were a bit depleted in the backs and gave us a hell of a game," Jeffries said.
"We were lucky to come out on top. We have a bit of an injury crisis on our side at the moment but we're looking to come out on top once again."
