About Us – Kingdom Boxing NZ

Kingdom Boxing NZ is more than a gym. We are a movement rooted in transformation discipline and purpose. Based in South Auckland we provide a safe space where individuals from all walks of life—young people battling inner struggles adults reclaiming their health and communities rebuilding from trauma—come together under one roof with one mission: to rise.

Founded and led by Sione Mercury a seasoned boxing coach and mentor Kingdom Boxing is home to fighters champions and seekers. Sione is also the Head Coach of the New Zealand Samoan Amateur Boxing Team a member of the New Zealand Boxing Coaches Association and a guiding force in the Auckland Boxing Association. His leadership is grounded in both excellence and compassion and his journey from fighter to community father sets the tone for everything we do.

We believe boxing is a tool for healing as much as it is for fighting. That’s why Kingdom Boxing runs unique programs like Journey Within—a life-changing pathway for men navigating addiction trauma and identity. In partnership with boxing training participants rebuild discipline and self-worth while being surrounded by accountability support and faith.

Kingdom Boxing is proud to support women through our Esther Gen initiative a powerful space for women to train grow and lead. With Julie Mercury as our Assistant Coach and the Samoan International Women’s Coach we stand for women’s empowerment through fitness and purpose.

We are also home to the NZ Samoan Amateur Boxing Team—a national platform providing Pasifika fighters with international exposure and cultural pride. Our fighters compete with heart honor and heritage backed by a team that includes Chairman Sione Mercury President William Tuilagi Leolahi Treasurer Julie Mercury and Secretary Rosalina Leolahi.

Our gym offers personal training youth programs competition coaching and community outreach. Every session is an opportunity to build strength in body mind and spirit. Whether you’re preparing for the ring looking for purpose or just want to train in a place that sees your value Kingdom Boxing welcomes you.

This is more than boxing. This is Kingdom.
