Auckland Icon Passes Away at 91

Les Mills Sr., a towering figure recognized globally as a founding father of the modern fitness industry and a distinguished former mayor of Auckland, passed away peacefully on June 29, 2026. He was 91 years old. The announcement, disseminated via PR Newswire from Auckland, New Zealand, marked the conclusion of a remarkable life. His family described him as a visionary who blazed trails across multiple domains: elite sports, entrepreneurial business, dedicated politics, and profound community service, leaving an indelible mark on his home country and the world.

A Formative Childhood and Athletic Awakening

Born in Auckland in 1934, Les Mills Sr.'s early years were shaped by significant challenges. Family records indicate a particularly difficult childhood, notably marked by the profound loss of his father when Mills was just 11 years old. In the wake of this adversity, he discovered a powerful outlet and a source of solace in physical culture. It was during this formative period that he drew deep inspiration from the renowned Charles Atlas strength training program. This program, popular for its promise of physical transformation through isometric exercises, ignited a passion for strength and physical prowess in the young Mills. This early, self-driven interest in fitness was not merely a hobby; it swiftly evolved into a formidable athletic career that would not only define his public persona for many decades but also lay the groundwork for his future endeavors in the fitness world.

From Olympic Athlete to Global Fitness Innovator

A Champion's Sporting Legacy

Les Mills Sr.'s athletic prowess was undeniable, establishing him as a prominent figure in New Zealand sports history. He proudly represented his nation at an impressive four Olympic Games, competing at the highest level in both the discus and shot put events. His dedication and skill were further showcased on the Commonwealth Games stage, where he achieved significant success. His competitive record includes a remarkable haul of medals: one gold, three silver, and one bronze. These achievements not only solidified his status as an elite athlete but also brought considerable pride to New Zealand. Upon concluding his active competitive career, Mills seamlessly transitioned into a new phase of sports involvement, serving as an elite international coach and a respected sports administrator. In these roles, he continued to contribute to the development of athletes and the broader sporting community, sharing his extensive knowledge and experience.

Building a Fitness Empire with Colleen

In 1953, a pivotal moment in Mills' life occurred when he married Colleen, an accomplished world-class track and field athlete in her own right. Their shared passion for sport and physical excellence formed the bedrock of a powerful partnership. Together, they explored various business ventures before strategically merging their profound interests in sport and commerce. This synergy culminated in the launch of their inaugural Les Mills gym in Auckland in 1968. The establishment of this first gym marked the genesis of what would become a global fitness phenomenon. According to detailed company history, the initial years of the business were not without their challenges, requiring resilience and innovative thinking from the couple. However, their unwavering commitment eventually led to significant success, fostering the growth of the enterprise into the highly respected Les Mills New Zealand (LMNZ) chain of gyms. Today, the LMNZ brand continues to hold a significant and cherished place within New Zealand's vibrant fitness culture, a testament to its enduring legacy.

Global Expansion Through the Next Generation

The family's vision for fitness leadership expanded dramatically on the global stage through the entrepreneurial spirit of the next generation. Their son, Phillip Mills, alongside his partner Jackie, founded Les Mills International (LMI). This new entity distinguished itself by focusing on the development and licensing of group fitness programs, rapidly evolving into a powerhouse within the global group training industry. The strategic leadership of Les Mills International was further strengthened with the inclusion of Phillip and Jackie's children, Diana and Les Mills Jr., who joined the executive team, ensuring the continuity of the family's influence and innovation. The international division achieved widespread prominence with the revolutionary launch of BODYPUMP. This innovative group workout program, characterized by its use of barbells and high-repetition strength training, quickly captivated fitness enthusiasts worldwide and played a pivotal role in cementing the company's expansive global reach and influence.

A Dedicated Public Servant and Civic Leader

Mayoral Leadership in Auckland

As his family meticulously cultivated the international fitness brand, Les Mills Sr. redirected his formidable energy and passion towards public service, embarking on a distinguished political career. He entered the realm of politics with the same characteristic determination and drive that had defined his athletic and business endeavors, as attested by family sources. His commitment to his city was profound, leading him to serve an impressive three terms as the Mayor of Auckland City throughout the 1990s. During this decade, he became a central figure in the city's governance, steering its development and addressing key urban challenges.

Transforming Auckland's Urban Landscape

During his extensive tenure as mayor, Mills spearheaded significant reforms and initiatives designed to enhance the quality of life for Auckland's residents. His administration placed a strong emphasis on several critical areas: strengthening local communities, undertaking substantial infrastructure improvements, and driving comprehensive urban regeneration projects. These efforts were not isolated but formed part of a cohesive and broader strategy aimed at fostering sustainable urban development and significantly boosting civic engagement across Auckland. His leadership during this period was instrumental in shaping the modern face of the city, addressing its evolving needs, and laying foundations for future growth.

An Enduring Legacy as a Kiwi Icon

Les Mills Sr. is fondly remembered by his family, colleagues, and the wider public as a true Kiwi icon whose influence spanned multiple generations and sectors. Even after his mayoral terms, he maintained an active and engaged involvement in both the dynamic fitness industry and the broader public life of New Zealand until his peaceful passing.
