There are 11 new cases of COVID-19 in managed isolation today.
The influx of new quarantined cases pushes the national seven-day rolling average of cases detected at the border to four.
The Ministry of Health investigation continues into the ‘day 12’ case at the Grand Mercure managed isolation facility in Auckland.
“As at 9am this morning, a total of 236 of the 272 returnees have now been contacted and 235 have returned negative test results so far,” the Ministry said in a statement.
“One person has returned a positive result which is classified as a historical infection on the basis of further testing and serology results. Historical cases are not considered to be infectious.
“The total number of returnees in this group has increased as further returnees take an exit test and isolate at home until the test has returned a negative result.
“The assessment was that this additional step was needed until today, and it has now been lifted for anyone leaving the facility from now on,” it said.
