He also said that it is likely some people won't receive their Covid Certificated for travel by 19 July.
Leo Varadkar has said that it is "ideal" but "not certain" that indoor dining will reopen on 19 July.
Speaking on RTÉ Radio’s News at One on Tuesday he said that the Government will be "taking advice" from the new expert group on antigen testing, headed by Professor Mary Horgan, on the resumption of indoor activities.
He added that it is “not certain” that indoor hospitality will resume by 19 July, confirming that the plan was to have a memo for Cabinet by Tuesday.
He also said that there will be "teething problems" surrounding the rollout of the EU Digital Covid Certificate as he urged people to "do your planning".
"I am sure there will be some people who don't get their certificates on time, so we'll have a call centre in place to help people out if that happens," he said.
"A lot of people think they need a PCR test to leave the country, they probably don't, but you may need one to return," he continued.
The EU Digital Green Certificate will allow people to travel anywhere in the EU provided they can prove they have been fully vaccinated, recovered from Covid-19, or have a negative Covid-19 PCR test.
While the pass came into effect throughout Europe last week, it won't be implemented in Ireland until 19 July due to delays caused by the HSE cyber attack.
