In a message on the site today (February 18), Smith confirmed that over 425 people had made contact with the review and the review had been in touch with almost 400 of them.
"The Review has had approximately 250 telephone conversations with witnesses, each of which has been noted," the update read.
"There have been in the region of 60 face to face witness interviews and further in-person interviews are scheduled over the next few weeks."
It continued: "The Review is close to finalising the appointment of a Child Protection Expert. It continues to liaise with the BBC in relation to the provision of copies of programmes and relevant documentation.
"The Review team would like to thank all of the witnesses who have given up their time to assist with this important task."
Former High Court judge Smith's report will focus on the culture and practices of the BBC while Savile worked at the corporation.
A second report by ex-head of Sky News Nick Pollard investigated the cancelled investigation into Savile by Newsnight.
That report found that the decision to drop the 2011 broadcast was "flawed" but also taken "in good faith".
An ITV documentary that aired last September accused the DJ of sexually assaulting teenage girls in the 1970s, prompting further witnesses and victims to come forward.
Savile had died almost a year earlier.
