The decrease in Pretoria's fortunes caused Nkausu to move to SuperSport United, who had just won the Premier Soccer League and were therefore considered one of the best teams in South Africa. SuperSport United Nkausu moved to SuperSport United ahead of the 2008–09 season. He had made a big leap from the lower reaches of the second division to the top of the first, and predictably made just five appearances in his debut season with the club, making his debut in the 1–0 win over Free State Stars on 30 August 2008. However, he still collected a winner's medal as SuperSport claimed a second consecutive Premier Soccer League title. Nkausu only made three appearances the following season, playing in SuperSport's victories over Free State Stars and Santos as well as the 3–0 loss to AmaZulu in March 2010. Again, SuperSport won the league title. 2010–11 was another frustrating season for Nkausu. He was included as a substitute in many of SuperSport's Premier Soccer League games, but was only used in two of them. He made his first appearance of the season against Orlando Pirates on 30 April 2011 in a 1–0 win. His only other appearance in 2010–11 was in the 3–1 victory over Vasco da Gama on 7 May, near the end of the season.

Part of the reason for this lack of playing time was the problem of Nkausu's South African residence permit, which he became eligible for in 2010 having spent five years in the country. In September 2010, despite agreeing a two–year contract with SuperSport, the club decided to wait until Nkausu's permit was granted until registering him, due to the PSL's limit on foreign players. Nkausu said "I have signed a new two-year contract here but the condition is that it will become effective the moment I can be registered as a non-foreign player, that is after I get my permanent residency. Right now I am waiting for the papers to be issued so that I can at least start being available for selection because as we speak I am not
