Crystal Kaua has an outstanding resume, both as a player and coach. During her playing career, Kaua made both the Sevens and 15's trial squads for the Black Ferns and played for the Aotearoa Sevens Māori side. She also played for the Waikato and Auckland Farah Palmer Cup (FPC) teams.
Since turning her hand to coaching, she has assisted many other women to succeed in rugby in New Zealand, Japan and overseas. Most notably, Kaua for the past 5 years, has been a full-time professional coach, the first women to do so for New Zealand Rugby, as the Black Ferns Sevens skills coach and performance analyst.
During the 2022 Super Rugby Aupiki season, Kaua supported Allan Bunting as an assistant coach for their inaugural title win. In 2023, Bunting passes the reins to Kaua who deservingly steps into this top position.
