From a touch rugby background, Williams only picked up sevens in 2014 and quickly impressed, debuting for the Black Ferns Sevens only a year later.
The mother of two has plenty of pace and strength and excels in defence which has helped her command a regular starting spot. A key member of the Black Ferns Sevens, Williams was one of four brother-sister combos in sevens at the 2016 Rio Olympics with her brother Sonny Bill suiting up for the All Blacks Sevens.
In recent times Williams has shown her versatility, moving from the backline to the forwards when captain Sarah Hirini was injured in 2019. She was part of the 2018 Commonwealth Games and World Cup winning squads.
