Presidential spokesman Mac Maharaj said Wednesday that "everything is moving OK" as 94-year-old Mandela rests at his home in Johannesburg after a hospital stay last month.
The former president received treatment for a lung infection and also had gallstones removed.
Maharaj says Mandela is "taking it easy" and is under "close medical attention."
Mandela spent 27 years in prison under apartheid and became South Africa's first black president in democratic elections in 1994.
