“Fearless and uncompromising in her stand for justice, equality and freedom for all, she saw her works banned as she challenged and straddled the great racial divide of the old South Africa,” Sanef deputy chairman Makhudu Sefara said in a statement.
Gordimer died on Sunday aged 90.
In a statement sent on behalf of the Gordimer family, law firm Edward Nathan Sonnenbergs said she died peacefully in her sleep at her Johannesburg home.
Her son Hugo, daughter Oriane and helpers were with her.
Sefara said Gordimer was instrumental in helping the late journalist Nat Nakasa establish his Classic literary magazine and was on hand to see him off as he left on an exit permit to New York, USA, in 1964.
“Hers was a voice that could be relied on to cut through the clutter of official bluster in her never-ending struggle for free media and freedom of expression.
“At 90, Gordimer has served her cause and deserves the rest due to the best amongst us,” said Sefara.
The law firm said a private memorial service would be announced at a later date.
