Sensei Kenny Nguyen (Godan)

Meet Sensei Kenny: A Journey of Dedication and Achievement in Karate
Sensei Kenny’s passion for Karate ignited when he was just 8 years old. His commitment and skill were evident early on, and by the age of 23, in 2004, he achieved his Yondan (4th Dan) under the examination of the WKF Shotokan - Ho Chi Minh City Association. That same year, Sensei Kenny trained in Kata and Kumite with the renowned Sensei Shiina and earned the prestigious National Referee Level B qualification in the Kata category. From 2002 to 2011, he served as the head instructor of a local Karate club, where his students earned numerous accolades in regional competitions.
After a 10-year hiatus, Sensei Kenny returned to Karate inspired by his children’s enthusiasm to follow in his footsteps. In mid-2021, he and his family joined JKS Takapuna, reigniting his dedication to the art.
In June 2022, Sensei Kenny ratified his Yondan under the esteemed JKS grading panel. His competitive achievements include a Bronze medal in the Male Senior Kata division at the 2021 NZ National Cup and a Silver medal in the same division in 2022, where he also placed 4th in the Male Open Kata division.
In November 2022, Sensei Kenny achieved both Examiner D and Instructor D certifications at the National Dan grading. The following year, in November 2023, he attended the JKS International Seminar in Tokyo, where he successfully earned his 5th Dan under the guidance of Shihan Kagawa and Shihan Norman Robinson.
Sensei Kenny’s journey is a testament to his unwavering dedication to Karate, both as a practitioner and an instructor, inspiring his students and family to pursue excellence in the martial arts.
Sensei Kenny: Inspiring the Next Generation at JKS Orewa and Beyond
Sensei Kenny now plays an integral role at the JKS Orewa Karate Club, working alongside Sensei Sean to nurture and grow the club’s community. He leads the JKS Orewa Little Tigers Program, sharing his passion and expertise with young Karateka and instilling in them the foundational skills and discipline of Karate.
In addition to his work with the Little Tigers, Sensei Kenny contributes to the coaching program for JKS Northshore’s elite athletes, helping to prepare them for high-level competitions and achieve their personal bests.
Sensei Kenny’s dedication to fostering excellence and his deep commitment to Karate make him an invaluable member of the JKS family, inspiring students of all ages and skill levels.

Sensei Nick started Karate in 1990 and trained on and off since then, primarily with JKS Shotokan.
With numerous old rugby injuries affecting his flexibility, he was ready to give up Karate in 2016. However, with Sensei Sean's unending encouragement, he got back into training in 2017, and with Sensei's guidance and whole hearted support, finally graded to Shodan in 2019.
Nick graded to Nidan in March 2022 under the watchful eye of the JKS grading panel

Nick is proof that you don't need to be a gifted athlete to attain a Black Belt – just determination, quality instructors and lots of sweat. With that attitude anybody can do it – if they want it!

Sensei Chris Baker (Nidan) Browns Bay Dojo
Chris – Nidan Grade Karateka (JKS)
Chris originally stepped into the Dojo in 2016 when his son Jacob started training under Sensei Sean, shortly after he joined in and hasn’t looked back. Drawing from his engineering background and rugby league experience, he applies a structured, analytical mindset to understanding Karate.
Over the years, Chris has earned his Nidan (2nd Dan), become a WKF tournament referee, and assisted coaching both juniors and adults at the club. His passion for teaching shines especially in his time leading the Little Tigers program where he aims to cultivate focus, respect, and enthusiasm in young karateka.
With his second son joining the dojo, karate has become a meaningful family pursuit. For Chris, each role whether it is as a student, coach, referee or father is part of a larger journey: one of growth, legacy, and the belief that every technique is an opportunity to learn, share, and inspire.
Still actively competing, Chris continues to test himself on the national stage. He has previously earned first place in Open Kata and second place in Open Kumite at JKS national tournaments.
Looking ahead, Chris hopes to contribute even more to the growth of karate in his region, mentoring upcoming referees and coaches while staying rooted in the tradition that first ignited his passion. For him, karate isn't just a practice… it’s a lifelong path.
Sensei Jacob Baker (Nidan) Browns Bay Dojo
Jacob Baker – Nidan Grade Karateka (JKS)
Jacob began his karate journey at the JKS dojo in 2016 under Sensei Sean. Shortly after, his father Chris started training alongside him and since then they have both graded together shared many experiences. Through years of dedicated training, Jacob earned his Nidan (2nd Dan), standing as a role model to peers and junior karateka alike.
Jacob has achieved first place medals in both Kata and Kumite at JKS national tournaments, a remarkable testament to his drive and competitive spirit.
He has previously assisted with the Little Tigers junior classes demonstrating patience and understanding. Outside of his training he has contributed as a WKF referee and has also achieved his JKS instructors and examiner level D qualification.
For Jacob, karate has become more than a physical pursuit, it’s a lifelong path of self-improvement. As he continues to train, teach, and referee alongside family and teammates, he remains deeply committed to the values of JKS karate and all it embraces.
