Hon JENNY SALESA: Because testing people who are asymptomatic at the border will not necessarily address the issues. During the incubation period, it is impossible to test for COVID-19, as per the advice we have from public health officials. Tests only work when symptoms are showing—this is the advice from the Ministry of Health and from the World Health Organization. We do not—I repeat: do not—want people entering Aotearoa New Zealand falsely believing that they do not have COVID-19 and not self-isolating for 14 days. Our instruction to travellers remains the same: self-isolation will help slow down the spread of COVID-19.
