Hon CHRIS HIPKINS (Minister for COVID-19 Response): I'm advised that four fully vaccinated people have tested positive on day eight or later in managed isolation and quarantine (MIQ) since 23 August—24,124 people have been through MIQ during that time. While that number is small, it still signifies the risk that exists in overseas returnees. It also highlights the rationale for introducing a period of home isolation to mitigate the risk of transmission after someone's seven-day stay.
