Gilbert's team-mate, Brittany Taylor, 13, was also in record- breaking form.
She set three new Taranaki 12 to 13-year-old girls' records on her way to winning three gold medals and one bronze medal.
In the 200m backstroke, Taylor's time of 2m 30.34s lowered the previous mark of 2m 31.06s, set by Rebecca Johnson in 2006.

Taylor's younger sister, Claudia, was named the 11-year-old girl swimmer of the meet after winning six gold medals and one bronze.
