Dunstan High School (DHS), Cromwell College and Mt Aspiring College all took part in the 3-day competition.
It also served as good preparation for the last and largest regatta of the season, the Maadi Cup, to be held at Lake Ruataniwha from March 18 to 23.
Up to 2000 secondary school pupils are expected to take part.
DHS rowing head coach Simon Smith said he was pleased with the school’s result — winning three gold, one silver and three bronze medals.
Twenty-two athletes from the school took part, many of whom had success at nationals two weeks ago.
"To change crews with a week’s preparation and to go in and win seven medals ... was really good," Mr Smith said.
"[We will be] coming together as crews, getting some continuity ... and sharpening up with some speed work," he said.
"It’s just building on top of what we’ve already got, the base we’ve got, the fitness, strength and speed."
Cromwell College deputy principal Greg Thomson said 13 pupils competed in the regatta, including one international pupil.
While the wind disrupted many of the rowers, "everyone tried their best on the water and enjoyed being part of their crews".
"In what is thought of as one of the hardest sports to take up, it was inspiring to watch these young people achieving personal and group milestones," Mr Thomson said.
Mt Aspiring College teacher Angela Rickard said pupils should be proud of their results.
The school won one gold and two bronze medals.
"The students represented MAC well and really supported each other to bring out the best in each other."
