But the win came at a great cost as they could have lost Mfundo Ndlovu to concussion after a red-card high shot from Tongan John Ika.
Ndlovu will have to follow the return to play protocols for concussion but the chances are slim he will play a part in the rest of the tournament, which ends on Sunday.
Still, the Blitzboks now face Scotland on Saturday to settle the pool as both sides registered two wins from two in their pool games.
Christie Grobbelaar scored twice, and was followed onto the scoreboard by JC Pretorius, Sakoyisa Makata and captain Shakes Soyizwapi as the Blitzboks eased into the playoff rounds with the victory.

The South Africa’s Womens’ Sevens team, meanwhile, will be looking for their first win in their final pool game after failing to score a point on day one of the Commonwealth Games Sevens tournament.
