She has held world titles in waka ama, and was in the championship-winning YMP women's hockey team this year.
“I've been doing Crossfit for about four years, but I picked up my training regime this year for competition and self-improvement,” Campbell said.
“I love being part of the Crossfit community and seeing the improvements in others and in myself.
“It was an honour to be among all those top competitors last weekend.
“I was stoked and proud to make the podium. It was totally unexpected, but I had to work hard to get there.
“I'd like to acknowledge the gyms I trained out of — Metcon Mauri, Crossfit Papamoa and Anytime Fitness.
“Also, there are many people to thank for helping me get there.
“It was a team effort, and I have an amazing group of friends and family who support me on this journey.”
