His office later said that "no official communication has been issued".
Pressure has mounted on Zuma to quit since Ramaphosa took over as ANC head in December, defeating the president's ex-wife Nkosazana Dlamina-Zuma.
"The NEC of the ANC has made a decision to recall President Zuma and the deadline is today".
It would be very hard though for him to resist a formal request to resign - known as a "recall", the report added. The Guptas and Zuma have denied any wrongdoing.
So far there has been silence from Zuma in response to Tuesday's ANC order, suggesting a power struggle behind the scenes with new party leader Cyril Ramaphosa.
ANC secretary general Ace Magashule yesterday
South Africans took social media to voice opinions for and against Zuma under the hashtag #Zumaexit with some wondering who is now running the country.
ANC Secretary General Ace Magashule broke the news to a packed news conference at the party's headquarters in Johannesburg on Tuesday, saying: "The NEC decided as follows: to recall comrade Jacob Zuma in accordance with the ANC constitution". "We're not playing around in terms of making sure that those who are responsible in the so-called state capture, they take responsibility for it", Mulaudzi said.
"The problem is that the ANC have tried to this - as they have put it - without humiliating the president", she said.
South Africa's opposition parties want the national assembly to debate a motion of no confidence in Zuma this week and for parliament to be dissolved immediately after that ahead of an early election. Prosecutors are also mulling reviving corruption charges tied to an arms deal two decades ago.
The ANC could throw its weight behind such a vote if Zuma, who has survived several no-confidence motions in the past, refused to resign. Neither of these appeared to yet be in play for the ANC, although the opposition Economic Freedom Fighters party has already submitted a motion for a parliamentary vote of no confidence.
The raid on the compound of the wealthy Gupta family in Johannesburg came as the African National Congress (ANC) said that a vote of no confidence in Mr Zuma would be held on Thursday.
Zuma met his likely successor Ramaphosa for one-on-one crisis discussions on February 6 described as "productive".
