The Momentum Proteas made history at Seddon Park in Hamilton on Thursday when they beat hosts New Zealand for the first time ever in a World Cup encounter.
They bowled out the Silver Ferns for 228 in 47.5 overs and then reached 229 for 8 in 49.3 overs to win by two wickets.
Sune Luus' team made it 4 wins out of 4 at this year's ICC Women's World Cup to stay firmly on course for the semi-finals.
Nelson Mandela Bay's Marizanne Kapp was named Player of the Match for the second match in a row after her heroics against England on Monday.
In Thursday's match, Kapp took 2/44 in her ten overs and was then instrumental with the bat in getting South Africa across the line, smashing a priceless 34 runs off 35 runs at number six in the order.
The pressure was on Kapp to see her team home and she further enhanced her reputation as one of the great all-rounders in the women's game.
Earlier, the classy opener Laura Wolfaardt struck 67 runs off 94 deliveries and Luus made 51 off 73.
South Africa are currently second on the table, behind Australia on net-run rate - the only other team still unbeaten in the tournament.
The Momentum Proteas play Australia next on Tuesday.
