Waikite survived a scare from Marist St Michael's, Whakarewarewa defended the Tai Mitchell Shield, and Rotoiti were simply too good for Ngongotaha when the Central Bay of Plenty local round kicked off.
The five-week tournament is being held this year ahead of the Baywide premier and first division competitions, which start on May 2.
It is a good chance for Rotorua clubs to test themselves before the Baywide and there is plenty of local pride on the line with the Tai Mitchell Shield and the Banner up for grabs.
Rotorua's two heavyweights Whakarewarewa and Rotoiti had straightforward wins on Saturday against division one sides Kahukura and Ngongotaha.
Whaka, who currently hold the Tai Mitchell Shield, raced away to a 59-5 win over Kahukura at Puarenga Park while Rotoiti smashed Ngongotaha 85-0 in Ngongotaha.
