Rt Hon JACINDA ARDERN: I absolutely agree with the member—it is the reinforcing of that message. I understand people's anxiety with the idea of information about where they've been being collected in an inappropriate way. You're absolutely right: people hold that information themselves. They have to give permission for it to be shared in the event they are found to have COVID-19. So we do need to keep reinforcing those messages, and I'd appreciate every member's help with that. On the issue of compulsory use of scanning, this issue that you've raised around people worrying about the role of Government, we factor that into our thinking; but we have debated whether or not compulsory scanning should be used. One of the greater issues for us has been enforcement. We've been worried about, for instance, business owners feeling like they would have to be the ones to enforce customers scanning before they come in, and there are lots of disincentives for that given it might hurt them commercially. So we've been trying to work through those issues, and it's still a live discussion.
