LEE RIRINUI
I bring a highly intelligent approach to delivering results. Over the years, I’ve had the privilege of guiding clients to multiple national and regional titles, podium finishes, and even international competition stages. As a former competitive surfer for New Zealand, I still enjoy catching waves and taking road trips. My firm foundation in Christ fuels my purpose and keeps me grounded in everything I do.
Nui Brothers hold a Bachelor of Sport, Health, and Human Performance (BSHP) Level 7 qualification, double-majoring in Human Performance Science and Sport Development and Coaching. Together we have transformed over 600+ lives.

JAMES RIRINUI
As an ICN NZ Men’s Physique Champion and x3 ICN Trainer of the Year award winner, I bring both proven expertise and firsthand experience to my coaching. I’ve guided countless lifestyle and natural competitive athletes through transformations that truly spins heads. My Christian faith underpins my work and fuels me to serve my clients to a high standard.
