Eight Swim Rotorua members went to the 2021 Aon New Zealand Age Group Swimming Championships, returning with one bronze and 15 other top 10 finishes.
The event, held in Wellington from April 19 to 23, attracted more than 450 of the top age group swimmers in New Zealand, aged 13 to 16.
Swim Rotorua head coach Aidan Withington said most of the team were younger and were competing for the first time at a national event.
"This was a great experience for the team," he said.
"All of them set new personal best times and had huge growth as athletes and people.
