Eli Byles played his 100th game for Whangamata in this first game of the season.
Meanwhile Tairua, in the Senior B division, powered past Ngatea by 61-7 to jump to the head of this competition with a crowd of local supporters in tow.
For 2020, the club entered the B grade competition to allow younger players to blend with older and returning players, without the pressure of the A grade.
"Previous years we had recruited guys from overseas in numbers, the COVID-19 virus would have created significant issues for us if we had followed that route leading into this year," said club president Brett Collins.
