The New Zealand swimming team earned six medals on the opening day of finals at the Australian age group championships in Adelaide last night, led by gold medal performances from Wellington's Callum Sinclair and Canterbury swimmer Sophia Batchelor.
Sinclair won the 12-13 years 200metre breaststroke final in 2:28.54 after topping the qualifiers, breaking Mitchell Donaldson's national age record by nearly two seconds in the process.
Batchelor, who has qualified for July's world swimming championships, dominated the 15 years 200metre backstroke, winning the final in 2:13.68.
There were also two second placings and two thirds in the finals with Hamilton's Bradlee Ashby second in the 15 years 200metre backstroke in 2:07.04, taking more than four seconds off his previous best.
Wellington's Cameron Jones pipped Auckland's Max Polianski for second in the 14 years 100metre butterfly final clocking 57.80, breaking his own national age record by more than half a second.
The Counties Manukau swimmer Ewan Jackson was third in the 17-18 years 400metre freestyle.
The championships continue until Saturday.
