In the earlier match, Suburbs B took down Ōhaupō B 31-10, after leading 19-10 at halftime.
Ōhaupō's tries were scored through big lock Jacob Reymer and evergreen Michael Monahan, who received a pass from veteran winger Sam Talaiti after a break down the left-hand sideline.
The Glenfield rugby centurion at No 8, Simon Fincham, was a force to be reckoned with, running hard at the opposition all day.
Halfback Baylee Davies dominated his opposite nine with some big tackles, while openside flanker Darryn Colville was involved in everything - earning himself player of the day for Ōhaupō.
This week the Ōhaupō senior sides will face Pirongia at Pirongia Domain with the McInally Cup on the line.
The cup goes to the club with the highest combined points across the two matches.
