Torque BJJ owner/operator and former BJJ world champion, Fabio Machado, opened the academy in May.
In just six months he managed to train his students to become national champions.
Originally from Rio de Janeiro, Brazil, Machado said he initially moved to Auckland to do his Ph.D. in Ocean Sciences, before he and his family moved to the Far North to start a BJJ and self-defence project.
"I started training BJJ about 30 years ago, but I already had a background in judo and Brazilian Luta Livre," Machado said.
"I became a two times BJJ world medalist, South American BJJ medalist and Rio de Janeiro champion, as well as a 2016 Rio de Janeiro top rank in addition to many other international open titles.
"I have also become a New Zealand regional judo champion and received an award in judo from the University of Auckland while still doing my PhD."
Machado said while he didn't compete in this recent NZ BJJ National tournament, he had encouraged his students to.
"I trained them prior and coached them during the championship and was at the tournament as the team's head coach," Machado said.
"BJJ is the fastest growing Martial Art in the world due to it being the most efficient.
"It is not only the effectiveness of BJJ as a self-defence tool that draws people to learn, it is also the discipline that comes with learning a martial art that appeals.
"Parents and caregivers of our community really value this aspect for their children, as the skills being learned are life skills which they will carry through for the years ahead."
Machado said with Kaitaia being a small community, he felt people had embraced the opening of Torque BJJ and the opportunity to learn from someone with his background.
He said Brazilian Jiu-Jitsu was not an easy martial art to learn, with the start of a person's journey often proving particularly frustrating.
"But this is where your character is tested and strengthened. It requires discipline, focus, and a willingness to evolve, but it also involves a lot of fun and a lot of teamwork," he said.
"When you learn BJJ or support someone else on their BJJ journey, you become part of a bigger family.
"We work together as a team and support each other to be the best that we can be."
Torque BJJ currently has around 50 students aged four to 53 who come from communities across the Far North.
Machado said he aimed to eventually open more classes, but wanted to take things one step at a time.
In addition to the weekly classes, Torque BJJ also runs special projects, The Coordination and Body Awareness Project (4-7 year-olds) and The Growing Confidence Project (8-14 year-olds).
Both programs aim to enhance a child's spatial awareness, develop co-ordination and motor skills, as well as to help them grow confidence, social skills, teamwork and develop good manners and respect for everyone on and off the mats.
"Even in this short period of time we have seen the difference our project has made for the children of our community," Machado said.
"It has been very motivating and gratifying to hear from parents and caregivers that our work has positively influenced their little warriors."
Torque BJJ offers Adult and children's classes, with children training twice per week and adults three times per week.
