"It is regrettable that there is a dispute going on amongst family members and we'd like that dispute to be resolved as amicably and as soon as possible," President Jacob Zuma's spokesman Mac Maharaj told AFP in an interview.
After a heated court battle, 15 Mandela relatives, including his three daughters and wife Graca Machel, won a court order to rebury the remains of his three deceased children on Wednesday.
Following the ruling Mandla launched a tirade at his relatives.
In a nationally televised news conference yesterday he accused one of his brothers of impregnating his wife and said others were born out of wedlock.

Mandla also accused other close relatives of money-grabbing and said Mandela's daughter Makaziwe was trying to "sow divisions and destruction" in her family.
Maharaj refused to comment on a nine-day-old court document which said the 94-year-old former statesman was judged to be in a "permanent vegetative state" and that his doctors had recommended switching off his life-support machines.
The filing was produced by a Mandela family lawyer last Wednesday and argued for an urgent court hearing so that a burial place for the critically ill Mandela could be finalised.
Mandela, who spent 27 years in prison for fighting white-minority rule and went on to lead the process of racial reconciliation as South Africa's first black president, indicated in the past he wanted to be buried with his family.
The moved graves meant there was confusion about his final resting place.
But Maharaj would not confirm if the document described Mandela's health accurately.
South Africa's first black president remained in a "critical but stable" condition, Maharaj said, but did not elaborate, citing doctor-patient confidentiality.
