Hon Dr DAVID CLARK: I'm not sure where the member has got those statistics from, but what I would say is that the most important thing here is that managed isolation is the most secure way we know of in the world. There's no global playbook for this virus. It's spreading faster than ever. And what we see in New Zealand is that that is working. We're one of only two countries, as far as we know, in the world that has managed isolation and quarantine facilities that are Government mandated, and we've got no evidence that any of the over 20,000 people that have been through have gone on to community transmit.
