The Commission of Inquiry into asset manager, the Public Investment Corporation (PIC), is in the process of compiling its interim report that must be submitted to the President by 15 February 2019.
The PIC, which is tasked with managing assets of over R2.083 trillion, including the Government Employees' Pension Fund (GEPF), is being probed on allegations of impropriety.
The commission completed the last week of the first public hearings at the end of January.
The commission said since it held its first public hearings, it experienced a spike in people coming forward to make submissions.
"We are grateful for the assistance they are giving to the commission.
"As we have mentioned previously, the commission continues to encourage all those with information relevant to its terms of reference to come forward," the Commission said in a statement on Monday.
While the commission thanked those making submissions, it warned against a witch hunt.
"We have noted with great concern numerous anonymous messages circulating on various platforms - including emails and on WhatsApp - alleging improprieties and implicating various individuals within the PIC or with links to the PIC.
"This has the effect of unduly putting in question the reputations of those named with no access to the necessary recourse mechanisms," said the Commission.
In light of this, the commission appealed to anyone with information to approach it, through the secretary or the evidence leader, whose contact details are on the commission's website.
"Provision is also made for anonymous submissions to the commission and in-camera hearings are available to those who, with good reason, do not wish their identity to be disclosed," said the Commission.
The Commission's public hearings will continue from 25 February 2019, until the end of March 2019 and beyond.
"The formidable line-up of witnesses will be shared before resumption of the hearings on 25th February 2019," said the commission.
