Abigail Dougherty/Stuff Two Papatoetoe High School students have tested positive for Covid-19, linked to an existing community case at the school. Experts say the news may impact Cabinet’s alert level decision on Wednesday. News of new community Covid-19 cases linked to an Auckland high school is likely tipping decision-making about an alert level change towards a “more cautious approach”, epidemiologist Dr Michael Baker says. On Wednesday morning, Covid-19 Response Minister Chris Hipkins said he was “optimistic” Auckland’s alert level 3 lockdown would be lifted after two days with no new community cases. However, following the announcement that two Papatoetoe High School students had contracted the virus – a classmate of the daughter, and the classmate’s brother – public health experts say more time at the status quo could be needed.
