The key moment came early in the second half when Highlanders back-up first five-eighth Fletcher Smith ran the ball out from his own 22, chipped ahead, regathered, and sprinted 50 metres before off loading to half back Kieran McLea to dot down.
Kaikorai had more ball and showed a lot of enterprise. But it also made more mistakes which proved costly.
A crowd of 710 people turned out for what was a good match.
