CHRIS BISHOP (National): Thank you for that answer—to the Minister. I suppose, I put the view out there that—my view certainly is, the reality is we are going to need some form of quarantine facilities and they should probably be purpose-built. Can the Minister, on behalf of the Government, envisage a scenario in which high-risk passengers from countries where COVID is quite prevalent automatically go into purpose-built quarantine facilities for a period of time, but low-risk passengers either quarantine, or isolate, I should say, at home for a period of time? And perhaps there's a middle-ground option for medium risk countries where the hotels continue to be used, or at least used for the short term, and phased out in the medium term. Is the Government considering a stratification system for isolation and quarantine along those lines? Because I certainly think that is something that there would be a great deal of interest in from the public. And perhaps I'll ask him to comment on that, and I've got some questions around other issues not related to managed isolation.
