Members of the banking inquiry committee have agreed to prepare a shorter report, about 250 pages, dealing only with new information that emerged during hearings.
The decision followed a meeting of committee members today to discuss difficulties that have arisen in framing its report.
The report will now consist of 11 chapters rather than the 750-page report envisaged.
It will be circulated to interested parties in early December to allow for publication in January as originally planned.
Inquiry chairman Ciarán Lynch told RTÉ’s Six One News that the draft report was never going to be the final document and the banking committee will now "composite some chapters into single chapters".
The Labour TD told RTÉ there is a great sense of unity and purpose among committee members, adding that all members want to get the final report over the line in January.
"There does have to be an acknowledgment that everybody has worked extraordinarily hard to get the draft report to where it actually was.
"That was never to be seen as the final product. The draft report that was published last week is something now that needs to be advanced.
"There's complete unity amongst the committee, in agreement that we now need to get a final report over the line in January."
