At least 5,000 people, including foreign dignitaries and senior political figures, are expected to attend Sunday's funeral ceremony in Mandela's boyhood home Qunu.
Once the initial public service has been completed, however, the moment of interment will, at the family's request, be a purely private affair, spokeswoman Phumla Williams told AFP.
"The family has indicated they want to make the burial a family matter," Williams said.
"They don't want it to be televised. They don't want people to see when the body is taken down."
A special stage and marquee have been erected for the two-hour public funeral service which begins at 8:00 am (0600 GMT) on Sunday.
As of last day evening, 3,000 members of the media had already descended on the remote site in the Eastern Cape.
