Minentle Noqhamka, 21, had her leg amputated after the vehicle hit her as the team was escorted away from the East London city hall on 5 November amid pushing and shoving by crowds of people, the News24 website reports.
At the time, police were quoted as saying that a case of reckless and negligent driving had been opened against the driver of the vehicle.
Noqhamka’s father Sithembiso confirmed her death, South Africa’s TimesLive newspaper reports.
“She was knocked by a police Nyala [armoured vehicle] on her legs. Her left leg was amputated at the hospital,” he is quoted as saying.
“It’s very sad for us as a family. We are still trying to come to terms with this.”
South Africa won the Rugby World Cup on 28 October after beating New Zealand in Paris and becoming the first nation to win the tournament four times.
