Also in record-breaking form was breaststroke specialist Jack Weston, who established new BOP marks in the boys 17-years 50m, 100m and 200m events.
Emily Spear and Milla Theobald, both 12, showed their mettle to take the bronze medal and fourth place in the open 1500m freestyle.
Milla and Emily also showed their fighting spirit with a quick return to the pool to take the silver and bronze medals behind teammate Bianca to ensure an amazing clean sweep for the Swim Rotorua club.
Ana Nagera was full of confidence to take the top honours in the girls 13-14 years 200m breaststroke.
Not only did Ana smash three minutes for the first time, but nearly dipped under the 2m 50s mark with a stunning new best time of 2m 50.02s.
Jasmine Hagan, 10, enjoyed a fabulous debut to take gold in the 50m backstroke with a swift time of 39.05 seconds.
Jasmine also picked up a silver in the 200m backstroke and a bronze in the 100m backstroke. Other top performers included Sam and James Baldwin, Paddy Baylis and Lina Stalhut.
It was great to witness Bianca's powerhouse racing despite taking on a heavy schedule.
However, the whole team did a solid job, and it was particularly pleasing to see Jack Weston and Ana Nagera regaining their top form. We also had some great performances from our younger athletes which augurs well for the future.
