Mrs Mugabe is accused of assaulting Gabriella Engels in a Johannesburg hotel last year
The South African government had initially granted the former first lady diplomatic immunity but was overturned by a court after Engels, challenged the decision.
There was no immediate comment from Mrs Mugabe or from authorities in Harare.
She has denied assaulting Engels with an electric cable, saying an “intoxicated and unhinged” Engels attacked her with a knife after the model had gone to see the Mugabes’ sons at the hotel.
Mrs Mugabe was seen as a potential successor to her 94-year-old husband Robert, who ruled Zimbabwe from 1980 until he was ousted in a coup late last year, at the time of the incident in a luxury hotel in Johannesburg’s Sandton district.
South African advocacy group Afriforum, which represented Engels, has dismissed Mrs Mugabe’s denial as a lie.
Mrs Mugabe has retreated from the limelight in Zimbabwe since her husband was ousted in the November 2017 coup.
