However Ms Shroff said there may be good reasons for delaying the report's release.
"If serious vulnerabilities have been discovered it's obviously important to get those closed as far as they can before going public.
"It's also important to get things right before you go public and we certainly wouldn't want to see them doing something that put the public's information at risk."
A spokeswoman for Internal Affairs Minister Chris Tremain said he would not comment until the report was released.
Labour MP Sue Moroney's members bill that would beef up the Privacy Commission's ability to police privacy issues in the public sector was drawn from Parliament's ballot last week.
She said the bill picked up recommendations for a review of the Privacy Act from the Law Commission two years ago which Justice Minister Judith Collins last year indicated the Government would enact via its own legislation.
"The Government has clearly been dragging its feet on addressing the privacy concerns, both through the legislation they've promised and now obviously with the delay in going public with the review from their own Chief Information Officer."
