The inequality between black and white households was "bad for reconciliation", President Jacob Zuma said on Sunday.
Zuma, speaking at the closing ceremony of the African National Congress' centenary celebrations in Durban, said: "The situation that white households have six times the wealth of black households should be a thing of the past."
Zuma, who referred to the 2011 census, said such a disparity was bad for reconciliation.
"It is bad for reconciliation and nation-building and all of us, black and white, must work to reduce and ultimate eradicate such a massive gap in the second phase of our country's revolution."
Referring to the ANC's history, he paid tribute to those who had contributed to the organisation's successes.
He also urged unity within the organisation saying that it was good for the party as well as the country.
