The championships at the Caledonian Gymnasium attracted more than 120 gymnasts from Otago and Canterbury clubs.
There were 15 grades contested.
In the top grade, Keziah Oliver, from Christchurch, won ahead of her provincial team-mate Mereana Rademakers.
Both of these gymnasts are trying to qualify for the Commonwealth Games later in the year, and used the championships as a good training exercise.
Otago gymnasts to the fore were Dale Hurring, who won the level eight grade, while Brooke Hannah finished second in the level seven grade.
Brooke Hastie was second in the level 10 grade, performing all her routines solidly.
Dunedin youngsters Sarah Morrison and Mikaela Walsh both performed well against some top competition in the level seven grade.
The duo are off to Australia next month to compete at the Australian rhythmic gymnastics championships.
