Early Life and Education of Clayton McMillan
Clayton McMillan was born in Perth, Australia, to an Australian mother and a Māori father from Matakana Island. His early life was marked by tragedy when his mother passed away from cancer when he was just six months old. Following this loss, at the age of three, he and his father moved to Rotorua, New Zealand, which he considers the cultural heartland of Māori life. It was here that he was raised by his aunt, Marlene, whom he regards as his mother and a matriarchal figure who has been a constant source of inspiration and support throughout his life. Growing up in a humble and hard-working home, he was deeply immersed in te ao Māori (the Māori world view). He attended Rotorua Boys’ High School, a school with a strong reputation for producing tough and talented rugby players. Before embarking on a full-time professional coaching career, McMillan had a distinguished decade-long career in the New Zealand Police, an experience that profoundly shaped his worldview, leadership style, and ability to connect with people from all walks of life.
Clayton McMillan’s Career
Clayton McMillan’s career in rugby is a tale of two distinct yet interconnected chapters: a successful playing career followed by an even more impactful coaching journey. As a player, McMillan was a formidable number 8, known for his physicality and leadership. He was a stalwart for his home province, Bay of Plenty, representing them in 113 matches and becoming one of a select group of players to earn a century of caps for the union. His playing career also took him to Japan, where he played for the Coca-Cola Red Sparks. It was during his time in Japan that he first transitioned into coaching, laying the groundwork for his future profession by serving as a player-coach.
Upon returning to New Zealand, McMillan methodically built his coaching resume from the ground up. He coached at various levels, including club rugby with Whakarewarewa, age-grade teams, and development squads in both Bay of Plenty and Wellington. His big break came in 2015 when he was appointed Head Coach of the Bay of Plenty Steamers. He led a significant revival of the team, culminating in their promotion to the top division by winning the Mitre 10 Cup Championship in 2019. This success did not go unnoticed, and his coaching portfolio expanded to the international stage. In 2017, he was named head coach of the New Zealand Provincial Barbarians for their match against the touring British & Irish Lions and, later that year, took the prestigious role of head coach for the Māori All Blacks, a position he held with distinction until 2023.
In 2020, McMillan joined the Chiefs in Super Rugby as an assistant coach. He was quickly elevated to interim head coach in 2021 and was later given the role permanently. Under his leadership, the Chiefs underwent a remarkable transformation. Inheriting a team that had struggled, he instilled a new culture and tactical approach that yielded immediate results. He guided the Chiefs to four Super Rugby finals in five seasons, establishing them as a consistent powerhouse in the competition and earning a reputation for playing an exciting and effective brand of rugby. His success with the Chiefs and the Māori All Blacks, as well as a successful stint coaching the All Blacks XV, positioned him as one of New Zealand’s foremost coaches. In a significant move for his career, it was announced in early 2025 that McMillan would be taking his talents to the Northern Hemisphere, signing a three-year contract to become the head coach of Irish provincial giants Munster Rugby, starting from July 2025.
