Despite only being their second win, plenty of bonus points from narrow defeats moves Ruapehu up to fifth and still an outside chance of making the top four come July if they can recover old form in Round 2.
Over at Memorial Park, Utiku Old Boys welcomed back key outside back Samu Kubunavanua and powered away in the second half to beat bottom-of-the-table Harvey Round Motors Ratana 41-16.
Down by a point at the break, Utiku scored four second-half tries to secure fourth spot on the table, with back Karl Farrell grabbing a double.
In the senior competition, Ruapehu continue to lead the table when they dispatched Marist Celtic 43-11.
However, Ruapehu still have their biggest games upcoming against Ngamatapouri and Kelso Hunterville, who were both impressive in the weekend.
Ngamatapouri comfortably disposed of Kaierau 50-10 at the Country Club, while Hunterville had another tough defence of the Stihl Shop Wanganui Challenge Shield - taking it down to face Speirs Food Marton, full of players from their defunct premier team, and coming from behind to win 25-17.
Tech picked up an important 25-13 win over Sealswinslow Pirates to sit clearly in seventh spot with four rounds to go until the championship and consolation groups are split.
