Baylis returned to Canberra where he represented New Zealand at last year's competition.
Baylis raced in the distance freestyle and butterfly events. His favourite 1500m freestyle produced a time of 15 minutes 58.17 seconds which was just outside his best time. He bettered his best time in the 400m freestyle to edge closer to breaking the 4-minute mark with a new time of 4 minutes 05.64 seconds. Baylis is still developing his butterfly expertise, but still managed to top his best times with a 1 minute 00.51 seconds in the 100m event, and 2 minutes 14.28 seconds in the 200m event.
Swim Rotorua head coach Alastair Johnson was also part of the New Zealand team and was proud of his two athletes.
"After four sessions of very intensive racing, we have come away with a personal best time strike rate of almost 90 per cent. Both Bianca and Paddy have excelled both in and out of the pool and have demonstrated that they are genuine international standard athletes.
"They along with seven of their Swim Rotorua team mates will be aiming to improve again at the National Short Course Championships [25m metre pool] which begins on this Sunday."
