The third and final session begins on Sunday at 9am and concludes at 1.30pm.
Radford said she was particularly excited about the prospects of some of the Swim Rotorua competitors.
Several of the swimmers produced outstanding performances at the Auckland Junior Championships held last weekend.
Swim Rotorua head coach Alistair Johnson said Paddy Baylis, 12, David Boles, 12, Bianca Donelley, 10, Anasetini Nagera, 12, and Jopae Nagera, 12, were a testimony to the young talent coming through the ranks of the club.
"After two full days of racing, the athletes set new national qualifying times for the New Zealand National Junior Championships in a total of 22 events."
Johnson said swimmers from across the country competed, including a representative team from New Caledonia and Tonga, and the action in the pool was fast and furious.
"Paddy, who turns 13 in the new year, improved a further nine seconds on his national qualifying time for New Zealand Division II Competition."
The coach said the young athletes displayed champion qualities with their thirst for learning and their competitive commitment.
"Bianca was in a class of her own, and dominated the freestyle events, claiming gold in the 50m and 100m freestyle and a silver in the 200m freestyle."
Johnson said the club had a further 16 swimmers who had achieved a Bay of Plenty qualifying standard and would be competing over the weekend.
