Authorities are reducing the number of passengers they check are self-isolating after arriving into the country, amid an the increase in numbers arriving in Irish ports and airports.
COVID-19 Passenger Locator Forms - which passengers are legally required to fill out when arriving in the country - will now be selected at random for follow-up calls.
However, the Border Management Unit (BMU) says they will ensure a "proportional cohort" from every flight is contacted.
Over 45,500 passenger locator forms were filled out between May 28th and June 30th, with officials saying 100% of passengers arriving here filled out the forms.
Figures from the Department of Justice show that over 29,000 people were called to check they were restricting their movements, but just 58% of people answered the phone.
Some passengers are exempt from a follow up call because they are travelling on to Northern Ireland or are staying in the State for less than 2 days.
Follow-up calls
In a statement, the Department of Justice explained: "The first calls are made 2 days after passengers have arrived into the State. For any passengers staying in the State for up to 14 days or more, a second call will be made on day 10 to ensure they are still residing at the address provided and self-isolating.
"If a passenger refuses to fill out the form, An Garda Síochána will engage with them, explain the requirement to fill out the form, encourage them to comply with the requirement and, if they still refuse, to enforce the Regulations.
"To date, nobody has refused to complete the form."
While the BMU has been making the follow-up phone calls, they will shift to 'focusing exclusively' on their main role of immigrating passengers as passenger numbers increase - with the HSE to take over the calls.
Meanwhile, Eoghan O'Mara Walsh - CEO of Irish Tourism Industry Confederation - said he thinks the 14-day quarantine rule should be relaxed.
He said: "We hope, come July 20th, the quarantine rule will be relaxed.
"There are other ways of managing and maintaining public health measures - in terms of testing, tracing, hand sanitisation, face masks... all of the good practice that could be deployed. We think they're more effective."
