Northland's Callum Prime proved a handful for his rivals at the recent Australian State Teams Age competition in Canberra.
The 15-year-old from the Northwave club saved the best until last for New Zealand's swim team, scoring their only victory of the meet when he won the 400m individual medley at the Australian Institute of Sport aquatics centre in Canberra.
Clocking a time of 4:25.81 to hold off the challenges from each Australian state team, Prime's winning performance backed up his second placing in the 100m backstroke (57.79) and a second in the 200m backstroke (2:01.84) on day two of the event.
Hayley McIntosh, Northland's other member of the New Zealand Age Group Team, took 13 seconds off her 800m time, recording 9:03:09, which would have seen her come second at the New Zealand Short Course champs.
She also did personal bests in the 100m and 200m freestyle, held her 400m freestyle time and secured two fourth places in team relays.
