Scuffles erupted outside the building as Zuma supporters clashed with rival ANC activists with at least one woman kicked and beaten with sticks, an AFP reporter witnessed.
The ANC's top six most powerful officials met Zuma late on Sunday at his official residence in Pretoria.
"I can say to you that there are different views, there was a dominant view at the NWC, but it wasn't the only view". This work will require years of endeavour, and we call on all South Africans to commit to supporting it.
President Zuma has abused the trust of South Africans.
He stepped down as ANC president in December after serving two terms as party leader. The Guptas and Zuma have denied any wrongdoing.
When asked about deputy president Cyril Ramaphosa, however, opinions turned, with 53% saying that the country's second-in-command was doing his job well. The "pending actions in parliament" appear to refer to a vote of no confidence in Mr. Zuma, to be proposed by opposition parties on February 22, and to planning in parliament for impeachment proceedings, which has been mandated by the courts.More news: Dow Jones falls another 500 points at open
Mbete said they did not want a repeat of this.
JOHANNESBURG-Jacob Zuma, once a Teflon leader who was acquitted of rape, escaped corruption charges and survived multiple no-confidence votes in Parliament, has become an embarrassment to his party.
Critics also claim Zuma allowed his friends from a powerful business family, the Guptas, to have so much influence that they "captured" the South African state. Party leader Mmusi Maimane said Zuma should be prosecuted for alleged corruption, amid speculation that the president might seek an immunity deal in exchange for his resignation.
". President Zuma must go not in order to shore up the governing party's election prospects for 2019".
The ANC will again meet over the matter of Zuma's exit on Wednesday.
That appeared to be borne out at the 2016 local elections, when the ANC lost ground to the opposition Democratic Alliance (DA) and Economic Freedom Fighters (EFF).
The South African Communist Party (SACP) had earlier accused Zuma of wanting to axe his deputy Ramaphosa, and further accused the embattled head of state of engaging in unsafe "ethnic mobilisation".
