Hon Dr DAVID CLARK: Most of the international travellers arriving on our shores right now are New Zealanders returning home. The vast majority of them will be COVID-19 - free. Nevertheless, we need to be able to welcome them back confident they won't inadvertently reintroduce the virus into our communities. That's why we'll continue to test new arrivals on around days three and 12 of their stay in managed isolation and quarantine, and a negative result is required from the day 12 test before people are allowed to leave. We also need to minimise the risk that those who come into contact with them during their travel and their arrival and during their managed isolation or quarantine do not contract the virus, and, if they do, that we quickly detect the infection and take appropriate action. Our new testing strategy features regular health checks and asymptomatic testing of all border-facing workers, and regular testing of quarantine-exempt people such as New Zealand - based aircrew.
