Southern athletes won three titles - Jason Boyce won the men's masters 1, 105kg class, Lesley Procter claimed the women's masters 3, 72kg class and Tom Hart clinched the junior male 93kg class.
The Wilks Formula, which factors in the weight of the competitor and the weight lifted, was used to calculate the winners.
Boyce completed a 205kg squat, 150kg bench and 240kg deadlift to clinch his title.
Procter pulled off a 72.5kg squat, 52.5kg bench and 130kg deadlift, while Hart managed a 245kg squat, 130kg bench and 260kg deadlift.
Dunedin athlete Orla Harris broke three national records in the women's 57kg junior class, with 117.5 kg squat, 72.5 kg bench and 295 kg total score, but did not win a title.
Canterbury retained the South Island Powerlifting Shield with 190 points to Southern's 175.
Ciara Corrigan won the junior female 63kg class, Ana de Joux claimed the overall women's award and Joel Larter was the overall men's champion.
There were 45 lifters at the tournament, Fowler said.
