The Western Bay side led 17-15 at the break and were perhaps unlucky when Adam McGarvey missed his third drop goal attempt of the game late in the clash.
Two Whaka milestones were recorded, with Aliki Kinsina posting his 100th appearance and Doug Edwards playing his 50th match for the Rotorua club.
Te Puke Sports continued their campaign for back-to-back Baywide crowns with a nine-try blitz of cellar dwellers Waikite, winning 55-3. New Zealand sevens player Jack Wilson touched down four tries, adding to the five he scored against Waikite in the first round.
Te Puke's win puts them seven points clear at the top of the table.
Opotiki broke up the logjam in the top five when they got past Rotoiti 37-25 in the Eastern Bay to move into clear third. Mount Maunganui picked up a bonus point courtesy of four tries when they defeated Greerton Marist 29-10 at Blake Park.
Rangiuru ended Kahukura's eight-game winning streak when the two division one sides squared off at Kuirau Park in Rotorua. An emphatic 46-13 has made the Te Puke side the team to beat in the Baywide second tier title race. Whakatane Marist sneaked home from Ngongotaha by a point, 27-26.
Paroa posted 51 unanswered points against Reporoa, Marist St Michaels scored a 29-17 win over Ruatoki and Poroporo upset near neighbours Te Teko 36-22.
Marist St Michaels booked the last berth in the top six to contest the colts championship round when they got past Whakarewarewa 40-12 in the last round of qualifying.
Marist join defending champions Te Puke Sports, Mount Maunganui, Tauranga Sports, Greerton Marist and Te Puna to battle for the 2012 colts title.
