The deal covers the 2023 and 2027 men’s Rugby World Cups, with the Nike’s first new set of Springboks jerseys set to be revealed in July 2023.
Nike takes over the SARU technical partnership from Asics, resuming a relationship that ended after a seven-year run in 2003.
The contract sees Nike produce playing kit for all of South Africa’s rugby union teams, as well as supplying off-field apparel and footwear.
For Asics, the decision to end its SARU partnership marks a shift in the Japanese brand’s strategic approach, with a move away from rugby union and consolidating around other sports.
Carsten Unbehaun, chief executive of Asics Europe Middle East and Africa (EMEA), added: “Asics has been a proud sponsor of the South African Rugby Union since 2014, supporting their national squads including the famous Blitzboks Sevens and Springboks teams.
