Racing in the New Zealand Motocross Grand Prix, Oamaru's Joel Meikle bagged three trophies, Cromwell's Sam O'Callaghan collected two and Courtney Duncan brought the women's grand prix title home to Palmerston.
Joel (12) had an "amazing" set of results, winning the junior 11-12 years 85cc class and then punching well above his age-group weight to claim the junior 12-16 years 150cc class title.
"He was up there with guys who are shaving," his dad, Justin, said of the latter achievement.
Riding in the junior champion of champions 85 and 150cc race against all ages, Joel finished second behind junior 13-16 years 85cc class winner Micah McGoldrick, of Rangiora.
"It was amazing.
"A really good performance," Meikle said.
He put his son's success down to his dedicated training regime and his recent step up to riding a more powerful 150cc, four-stoke Honda.
After the 2009 Woodville event, Sam (16) had his sights set on a top result in the junior 14-16 years 250cc category.
"I got third last year in this class and I was hoping to come up and win it."
Recording 1-2-4 finishes granted him his wish and a strong run in the junior champion of champions, 125 and 250cc race netted him a second-place trophy as well.
Sam, who will begin a building apprenticeship in his home town this year, moves up into the senior classes when he turns 17 in March .
A stroke of misfortune resulted in Courtney recording a DNF in the junior 13-16 85cc class after her throttle jammed.
Although it robbed her of the chance to place overall against the boys, she went on to win the last race "by quite a bit", she said.
Her victory in the women's grand prix was by a convincing 13 points over Taupo's Alex Dillion.
Courtney (13) plans to race in Australia this year, as well as continuing a competitive national campaign.
Another Otago rider who had a stellar result was Hayden Scorringe, of Dunedin, who leapt from fourth to first in the final weekend of the three-round Super motard South Island Cup.
Achieving the overall title in only his second year of racing was a unexpected thrill, he said.
"I knew I had a mathematical chance of winning.
"I felt confident coming into the round but I knew there was some real fast guys racing."
He credited the twisting nature of the Timaru track as suiting his style.
Having grown up in the South Canterbury town and attending high school there, it was his favourite circuit.
Scorringe raced over the past three consecutive weekends at Ruapuna Raceway, Teretonga Park and Levels Raceway.
