"It has been a really good showing from our team, especially from the younger members. I was particularly pleased with those swimmers who made their competitive debut as they raced with good skills and lots of enthusiasm.
"Whilst the Summer Sizzler event is an annual fixture in the regional calendar, we do take great pride in providing an awesome event for the local community. Putting back into the Rotorua community is very important to us, and we are very proud of our involvement and support for local swimmers of all ages."
