Rt Hon JACINDA ARDERN: Of course we have changed rapidly the managed isolation process. We in April, of course, moved very quickly away from a system that many countries still use, where they have returnees just self-isolating at home, to requiring everyone to go into facilities. Now, my recollection is that we have had somewhere in the vicinity of 40,000 people going through Government-run facilities. That is significant. Once we had that regime set up, we moved to increase the controls around those. We now have them managed by Defence Force personnel, and even today we've taken new steps again to scale back the use of private contractors, scale up Defence Force, and, where we are using security, directly engage them by the Ministry of Business, Innovation and Employment and make sure they're paid a living wage. We have always looked for improvements and made them all the way through as part of our response.
