Prime Minister Jacinda Ardern has foreshadowed a “doubling in cases” of COVID-19, prompting National leader Judith Collins to call for the release of advice on Auckland’s drop down alert levels, Newshub reports. “Case numbers were trending down but are now clearly on a steady rise since Auckland left level 4. When will the Prime Minister release the health advice relied on to make the decision to reduce restrictions?” Collins said on Tuesday. Ardern said Delta has made this outbreak much trickier than dealing with the original Wuhan strain of the coronavirus.
