The Health Minister is being accused of mismanaging the country's mandatory hotel quarantine system.
It follows the announcement the booking system has been 'paused' as there aren't enough available rooms to meet demand.
59 countries are currently on the hotel quarantine list, and a further 16 are to be added from tomorrow morning.
Minister Stephen Donnelly has suggested walk-ins are contributing to the capacity issue, and says there will be more beds from Monday.
Co-leader of the Social Democrats, Catherine Murphy, says the capacity problem should have been dealt with long before this point.
"You'd have thought that this would have been managed in some significant detail, and additional capacity Brough on very quickly.
"It's not as if there's a shortage of hotel rooms in Ireland, and there's a huge demand at the moment [for hotel quarantine].
"It's very difficult to figure out why this has ended up with a four or five day wait - I expect that it will cause serious problems for some people."
