The semi-final match will kick off at 15h18, with the first semi-final, between Argentina and Colombia, scheduled for 14h56.
South Africa's two victories came in commanding fashion, with the Bok Women finding good early form, which bodes well for the big dance on Sunday.
In their opening match, the Springbok Women's Sevens team started like a house on fire, playing with pace and precision. They scored early when Ayanda Malinga stepped into space and when Maria Tshiremba scored a minute later, the home side were 12-0 up in no time.
Another Tshiremba try earned her a brace, while Shiniqwa Lamprecht also carried a couple of defenders over the line to score her first try for the team.
Leading 24-0 at the break, SA coach Renfred Dazel made early changes off the bench and both Kayla Swarts and Alicia Willemse made their debuts in green and gold.
Nadine Roos used her pace to secure a fifth try, while Felicia Jacobs also dotted down before the final hooter.

Tshiremba opened the scoring against Czechia with a great burst of speed down the line, beating her opponent with pace down the left-hand side. Malinga then finished a great move with a run down the other side of the field to extend the host team's lead to 12-0.
Adding to their attacking strengths, the defensive pressure by South Africa forced Czechia into mistakes and they conceded several penalties at the breakdown. They conceded a yellow card for a high tackle as well and Roos ran 50m to score after Mathrin Simmers switched play to the blind side.
The momentum was all South Africa's and after a quick tap penalty, Jacobs quick tapped and scored, with Roos converted for a 26-0 win.
The match against Kenya will be a fiercely contested affair, according to Zintle Mpupha: "They are a good side and they always demand the best from us in any game we play and tomorrow will be no different. We will have to bring our best tomorrow."
