He said they had worked hard and received lots of support from their family and whanau.
"For young people they are really composed, especially when they are put under pressure situations," he said.
"They had good preparation and showed good attitude in most of the trainings, which can be quite intense."
Whata said the team promised a lot for the future and they had built really good character.
"They are a really tight group that works well together."
The team which includes Anania Tangohau, Dekoda Roberts, Lefu Hura, Jahzell Roberts, Aimee Whata and Hinemoa Raupita went up against 30 other waka ama sides in their division.
Despite the large field, the Rotorua girls won in style in both the 250m and 500m races, winning by seven seconds and 12 seconds respectively in each final.
In-between those two finals on Tuesday they also won the W12 500m final.
For the W12 event they teamed up with another six-girl team from Hamilton who were also involved with the Te Toki Voyaging Trust club.
The girls actually finished second in the W12 final but moved into the gold medal position after the winning side copped a time penalty.
Steerer Aimee Whata said it felt great after winning their third title of the day.
"It feels really good. We tried to get it last year but we didn't," she told Maori Television.
Aimee said they "went hard all the way" on Tuesday to win their gold medals.
The Waka Awhiowhio Te Toki Voyaging Trust under-16 men's team, which included six Rotorua paddlers, also won a gold on Tuesday in the W12 500m.
