Pickett, who is schooling at St Peters Lutheran College in Brisbane and swimming for the powerhouse St Peters Western club over there, won the B final of the 50m fly in a time of 25.21.
It was 0.30secs under the record he set in March at the Associated Independent Colleges championships in Brisbane.
He had already bettered that time in his heat (25.46).
He clocked 50.69 as lead-off swimmer as North Shore finished second to Howick Pakuranga in the 400m free relay.
The previous record was 51.21 set by Pickett at the same March meeting in Brisbane.
Former Comet Swimming Club member Emma Godwin, now with the Heretaunga Sundevils, won the women’s 200m backstroke title last night.
