Mount coach Rodney Voullaire was happy with the way his players performed in the wet.
"We couldn't really do much with the ball going wide so we kept it under the jumper for a bit, which was good," said Voullaire.
"I thought Te Puna would have done that more because they were making some good yards, but they went to a bit of a kicking game and going wide.
"It played into our hands a little bit. The tries they did score were in close and playing multiple phases, and they sort of broke us a little bit.
"Yesterday's scores were really surprising, but we are week-to-week and if we stick to our guns I think things will look good for us at the end of the season.
"We'll focus on the teams we have already played and our video analysis. The guys themselves go through a process on the Tuesday to nominate areas of attack. It's good to put the onus back on the boys."
It was back to business as usual for defending champions Te Puke Sports with a comprehensive 34-5 win against Paroa.
The result lifts Sports into second place on the ladder, four points clear of Marist and six ahead of the fourth-placed Mount.
Rangataua was outscored three tries to two, but managed to sneak a draw to improve their chances of staying in the premier division next year.
Tries to Shane Ririnui and Saul Chase, and a penalty and a conversion to Ririnui, were enough for Rangataua to claim a share of the points to take sole possession of ninth place.
Rotoiti tipped over Whakarewarewa in the round's other match to further throw the competition wide open. Whakarewarewa's inability to claim a bonus point leaves them in a share of fifth place with only seven points back to eighth.
