GKR Karate is a family karate club that teaches karate as "fitness with a purpose", with classes for children, adults and whole families. The club's stated aim is to develop strong, humble and brave people and healthy communities, and it teaches self-defence alongside values such as confidence, discipline and focus. Free trial classes are offered, and the website lists several locations, with this one at 23 Veronica Street in Kumeu. The club also has tournaments for members who want to compete and publishes articles from its Shimbun magazine.
Parents and members who have written about the club say the discipline and confidence they gained have changed their lives, and that the club's sense of family is one of its strengths. One parent said their shy, bullied son became much more confident after two years of training. Another said the family trains in the same class as their two children, which they value. Several adult members say they gained friends, fitness and confidence, and one parent said their daughters grew in confidence and found a non-violent way to deal with bullying.
