In her first national age-group meet, Amy TeMaro (Carterton) qualified for the final of the girls 12-13yrs 50m breaststroke, placing 10th in 39.11s. Her heat time of 39.05s was a personal best.
Highlight of opening day action was the performance of Hawke's Bay teenager Bobbi Gichard.
The 13-year-old broke the national record twice in the 200m backstroke and also went under the qualifying time for the world junior championships.
The Greendale club swimmer broke the old national record held by the super-talented Sophia Bachelor by nearly 2s in the morning heats, clocking 2:17.32, and then posted 2:15.61 in the evening final.
It proved a night for the 13-year-olds with Auckland's Gabrielle Fa'amasuili breaking the national 50m freestyle record as the lead-off swimmer in the 4x50m relay and Satory Dobbie from Christchurch won the 50m backstroke in 30.86s and the 200m butterfly in 4:22.17.
