Mount Maunganui scrapped harder than expected in recording a three-tries-to-two victory over an improving Rangiuru at Blake Park, while Te Puna managed to pick up the points in a low-scoring affair against Opotiki.
The tightest match was contested between Whakarewarewa and Rotoiti, with the result coming down to the final seconds when John Ririnui stepped up to slot a difficult conversion, breaking Rotoiti hearts to steal the match 22-21.
Te Puke Sports kept their healthy competition lead by delivering the weekend's most lopsided result of 28-6 against Greerton Marist.
The results mean Tauranga slips back into fourth spot, 11 points back of Te Puke Sports.
Whakarewarewa lie in wait a further three points back, but have the luxury of a guaranteed five competition points and just one match over Queen's Birthday weekend following the union's decision to allow their round 12 match with Opotiki to be played in the pre-season.
