The Editors' Code of Practice Committee has extended the period of public consultation on changes to the Editors' Code by a further two months until 17 April.
The extension will give the committee of editors, headed by Daily Mail editor Paul Dacre, more time to consider possible changes to the code.
The body holds a review every year as a matter of course, but this one has added importance because of the Leveson report.
Any review will have to await planned changes to the composition of the Code Committee. Lord Justice Leveson said editors should not have a decisive role on the committee and it remains to be seen how many lay members will be brought into replace the current committee, which is all editors.
Meanwhile the NUJ has said it is boycotting the consultation because it says that it has been frozen out of industry discussions about the future of press regulation.
NUJ general secretary Michelle Stanistreet said: "Despite Lord Leveson's damning criticism of the Press Complaints Commission, the Prime Minister is allowing Lord Hunt to conspire in secret with the same cronies – the proprietors and the editors of the national press.
"In his recommendations Lord Leveson said 'greater transparency about meetings and contacts should be considered not just as a future project but as an immediate need, not least in relation to interactions relevant to any consideration of this report'. Are his words being ignored so soon?"
