The Kaikorai forwards took control from the start and paved the way for a commanding win over Green Island at Miller Park.
The tight forwards dominated the scrum, while prop Blair Laughton also made ground with his driving runs and the pick and go.
Lock Blair Tweed gave Kaikorai control of the lineout and the loose trio of Nathan Hull, Mitch Clarke and Adam Hill dominated the breakdown.
Kaikorai scored five tries in the first spell to lead 31-0 at the break and added two more converted tries in the second spell.
Kaikorai had remarkable ball control in the slippery conditions that became muddy in the second spell.
First five-eighth Matt Te Tana was the master tactician and varied the attack, centre Jayden Spence ran straight, and pacy fullback Tony Ensor cut through the defence on the counter-attack.
The game was virtually over when Kaikorai led 31-0 at the break.
Green Island played better in the second spell and offered more than just token resistance.
Simon McCarthy was tidy in the front row, No 8 Jackson Hemopo was solid on defence, halfback Dean Moeahu used his experience on defence and centre Roma Saulieoge made some strong bursts up the midfield.
Kaikorai 45 (Tony Ensor, Jayden Spence, Dan Hyndman, Matt Te Tana, Adam Hill, Matt Cowie, Callum Wardell tries; Cam Rutherford 5 con), Green Island 7 (Andre Clarke try; Joe Bartlett con). Halftime: 31-0.
