Although qualified, uncertainty whether the event would go ahead - due to Covid-19 restrictions - did mean there was a longer gap between qualifications and the national event.
Once a new date was set, the girls' hard work was put on display at the national event over the two-day period in early December.
The event is scored off eight workouts over two days, with each workout score tallied up to their overall score at the end of the weekend.
Abbie, who was competing in the 16-17 year female division, had a near-perfect weekend and even coming off a hamstring injury managed to find herself in first place overall and standing as national champion at the end of the weekend.
Stella, who was competing in the 14-15 year female division, had a very hard-fought battle with the top three girls.
The three bounced between first and third for most of the weekend, with Stella putting in some impressive performances in the swim event and the running event.
At the end of the weekend Stella wound up third overall in her division.
The girls' hard work and training over the past year came through strongly going up against New Zealand's fittest girls.
Both girls are still just as hungry to carry on their dominant performance next year, with some bigger targets to come.
The entire team at CrossFit Assiduous on Rickit Rd offer their congratulations to the pair for representing the gym and doing them proud.
