The powerful South African winger and former World Rugby Sevens Player of the Year joined Ulster on a two-year deal in the summer of 2024.
A destructive and dynamic winger, who is known for his work-rate, Kok’s all- action play has earned him the nickname ‘Tarzan’, with a nod to his athleticism and flowing locks.
The 31-year-old is a former Blitzbok champion and has been a stalwart for his nation in the Sevens game, with honours including a 2014 Commonwealth Games Gold and a bronze medallist at the 2016 Olympic Games in Rio.
