Zenani died in a car crash two days after her 13th birthday on her way home from the opening concert for the Soccer World Cup last Thursday.
The funeral would be held at 10:00 in the chapel of St Stithians College, 42 Peter Place, Lyme Park, Sandton.
Foundation spokesperson Sello Hatang said her family would be accommodated inside the chapel, and a marquee would be erected for others wishing to express their condolences.
Apart from the tragedy of the teenager’s death, it also put paid to hopes that Mandela would attend the opening game on Friday night between Bafana Bafana and Mexico, as the grieving family felt attending the game would be inappropriate.
She is the granddaughter of Zindzi Mandela, who is the daughter of Mandela’s second wife Winnie Madikizela-Mandela.
The driver of the car, Sizwe Mankazana, is the 23-year-old son of Zindzi’s partner.
He was initially arrested, with police saying he would be charged with drunk driving and culpable homicide, but the case was struck off the roll pending further investigation.
He would appear in court on July 26, two weeks after the World Cup. SAPA
