Meanwhile, ISMI Chief Executive Neil McDonnell called on the Government to "get on with it" and introduce State-endorsed antigen testing in workplaces, such as essential retail, grocery and warehouse distribution.
Mr McDonnell said businesses were really disappointed that click-and-collect services did not resume this week, as there are whole sections of the retail trade that have been closed for months.
Speaking on RTÉ's Today with Claire Byrne, he said the country is "far enough into this" to be able to introduce measures to mitigate risks.
He added that figures pre-Christmas did not support the notion that there was any material rate of viral transmission in non-essential settings.
