Hon CHRIS HIPKINS (Minister for COVID-19 Response): In terms of the Bluetooth technology, we don't have that information, because we don't collect that information. One of the basic things about the COVID Tracer app is that people collect their own data. They get notifications about whether they may have been exposed, and they respond based on that. We don't collect all that information. Some of the countries the member likes to laud do collect that information, and they use it for a lot more than just tracing COVID-19 contacts, which is not something that the New Zealand Government has been willing to do.
