The Cromwell College pupil has just returned home after a stellar showing competing in Brazilian jiu-jitsu in the United States.
The self-defence martial art and combat sport is based on grappling, ground fighting and submission holds.
Shyla has been involved in the sport for eight years and has a swag of New Zealand and regional titles, including 43 gold medals, testifying to her ability and dedication to the sport.
While in the United States, competing against a larger pool of athletes, Shyla won three state titles — New Mexico state champion, and North Carolina state champion in two weight classes — as well as North American Grappling Association (NAGA) North American champion and a silver and bronze medal in the NAGA world championships.
"I kind of said before we left, ‘look, I believe she is the best in the world’ and I didn’t have the context of seeing her compete over there."
Shyla won a bronze medal at the world championships when she was 9, and the family had to decide if they wanted to "push hard".
However, Mr Mulholland said he wanted it to be "organic", something she chose to pursue herself.
Joining the Magnus Martins BJJ Team in Cromwell and training under coach Jason Senna Magnago Smith reignited a fire for the sport in Shyla and she found herself training more than two hours a day because she loved it so much, Mr Mulholland said.
In the US, she was competing in expert divisions in her weight range and up to two divisions higher.
"I honestly believe after getting back from [the US] that she still is the best in the world.
"I feel probably more confident saying that now than before we left," he said.
Shyla said she loved the international competition.
With a successful year under her belt, Shyla plans to return to compete in the US in April, this time with the world championship title in her sights.
