Director-General of Health Ashley Bloomfield was then briefed and COVID-19 Response Minister Chris Hipkins was told ahead of a 1pm press conference that day.

The fact the border worker hadn't been tested for five months wasn't revealed to the public until April 14, when Carolyn Tremain, chief executive of the Ministry for Business, Innovation and Employment (MBIE), told a parliamentary committee. The Government is coming under fire for sitting on the information for six days, but Ardern says the delay was necessary due to a "mismatch" in what the testing data showed and what the border worker had told them.
