More than 44,000 Covid-19 tests have been carried out here in the past week.
3.3% of those came back from the lab as positive for the virus.
Testing capacity now stands at 90,000 plus per week, with a target of 105,000 expected to be hit on Monday.
Chairman of the Covid-19 Expert Advisory Group, Cillian De Gascun, says the extra capacity in the system means they can once again look at broadening the criteria for testing.
"We're learning more about the disease all the time, so there are less common symptoms or new symptoms that we're associating with the infection.
"We're hearing anecdotally that maybe some GPs aren't referring the forward because strictly speaking they aren't within the case deffiniton.
"We're keen to broaden that out, we want to test more, we want to drive down that positivity rate."
