BBC reports that a decision on whether to extend Covid passes to pubs and restaurants will be made at the "last minute", First Minister Mark Drakeford has said.
Ministers are to consider whether to expand the scheme over the next week, with the next Covid rules review due on Friday.
Mr Drakeford said the emergence of the Omicron variant has led to knowledge and circumstances developing "so fast".
But the first minister told Politics Wales he did not think the Welsh government would be considering extending passes to hospitality if it had only been dealing with the dominant Delta variant.
He said: "We've got another week to go. We will learn a lot in that week about the Omicron virus.
"If we were to do it, it would simply be to help those businesses to stay open and still attracting customers through the door because people would feel confident that everybody else in that setting were either vaccinated or had taken a lateral flow test.
"But we haven't made that decision, and we won't make that decision right up until the day we have to, because circumstances and knowledge are developing so fast around the new variant that you ought to wait to have the maximum amount of information that you can."
Sam Rowlands, Conservative Member of the Senedd (MS) for North Wales, said the government should ensure "every part of our energies" is put in to rolling out booster jabs rather than extending use of the pass.
"With that you could see much better walk-in centres - rapid roll-out of walk-in centres across the country," he said.
