World champions New Zealand recovered from a slow start to defeat a spirited South Africa side and seal their spot in the Women's Rugby World Cup semi-finals.
The Springbok Women, appearing in their first Women's World Cup quarter-final, opened the scoring in Exeter through prop Babalwa Latsha.
The Black Ferns responded through centre Theresa Setefano and teenage wing Braxton Sorensen-McGee, but Aphiwe Ngwevu's try levelled the game at half-time to cap off a remarkable first-half performance by South Africa.
However, Allan Bunting's side clicked into gear to score five second-half tries to set up a semi-final against either Canada or Australia, who play later on Saturday, on Friday in Bristol.
Full-back Renee Holmes scored twice, with Sorensen-McGee, the tournament's top try-scorer, and number eight Kaipo Olsen-Baker also grabbing two scores.
South Africa managed to finally cross late in the second half through Lerato Makua to finish off a memorable World Cup campaign on a high.
Replacement Katelyn Vahaakolo was the final try-scorer of an entertaining game at Sandy Park.
