Like Pickett, he confounded expectations by improving his 16th ranking to take bronze in the 200IM.
Ruby Matthews (15) broke two Bay of Plenty records - missing bronze in the 100m breaststroke by 0.01s but winning silver in the 200m breaststroke.
In other results, Rhianna Maxwell (15) and Benji Rowe (14) both qualified for three finals, George Culling (14) swam four personal bests, Samantha Carter (14) recorded three top-10 finishes, Danielle Spreadborough (13) registered personal bests in all six events and Damian Potts placed fifth in the 200m fly finals for 15-year-olds.
Pickett, Matthews, Chaney, Rowe and Maxwell all qualified to compete at the Victorian Age Championships in Melbourne in December, with Pickett, Matthews and Chaney also selected to attend the New Zealand Development Camp in Rotorua in September.
Coach Stefan Swanepoel was thrilled with the performance of the largest team the club had sent to the champs in some years. "The standard was very high, so for our swimmers to stand out and then have our swimmers selected for a camp with the best young swimmers from around the country at a high level is amazing for them ... we've had very talented swimmers that have come through our programme ... but last year at this meet we had one medallist. For these guys to go in and claim five gold medals is just unreal. It's been a coach's dream week, really."
Swanepoel said the breaststroke craze that has gripped his pool is a fairly recent phenomenon that is easily explained.
"Josh Pickett has set such an example of what can be done in breaststroke and his clubmates are following suit."
