New Zealand’s spin trio of Eden Carson, Leigh Kasperek and Melie Kerr teamed up to take eight wickets and roll the South Africans for a measly 92 runs on Sunday night.
Carson (two for 21) removed both openers and Kasperek (three for seven) and Kerr (three for 13) ripped through the majority of the rest of the batting order.
South African captain Laura Wolvaardt tried to lead a fightback with 33 from 37 balls, and Annerie Dercksen (19) put up some resistance as well.
The White Ferns breezed through the chase. Kerr scored a run-a-ball 37 and captain Sophie Devine whacked 35 not out from 24 balls.
Victory was sealed in the 15th over.
It was a good win for the White Ferns. South Africa made the 2023 final and are expected to feature strongly again.
