They won three out of four games on Saturday to progress to the section one competition on Sunday, where they won all four of their games to win the title outright.
They finished ahead of last year's winners from Napier.
A Rotorua composite team won the section two competition which included John McGregor, Cyril Goss, Graeme Goss and Irene Goss.
Ngongotaha Bowling Club president John McGregor said the competition had boosted in popularity since they changed it to an optional event last year.
The competition was full four months ago, with 28 teams entered. One of New Zealand's best lawn bowlers Peter Belliss was also competing at the weekend.
