They had been returning home from a traditional ceremony.
Co-operative governance and traditional affairs minister Nkosazana Dlamini-Zuma and KwaZulu-Natal premier Sihle Zikalala, accompanied by transport MEC Bheki Ntuli and social development MEC Nonhlanhla Khoza, were expected to attend the funeral.
However, due to the large number of people who arrived at the funeral, their attendance remained unconfirmed early on Saturday.
“It's an unusual accident in the sense that all the people who died belong to the same family. There are 13 of them who passed away and two are critical in hospital.
“So it is a real tragedy for the Mndali family,” Dlamini-Zuma told the media after the accident.
