Hon CHRIS HIPKINS (Minister for COVID-19 Response): Mr Chair, we set out some thinking—some early thinking—not long before this current lockdown, around what a future reopening might look like and how we might transition from a position where the border is not quite hermetically sealed but certainly very, very restricted compared to what it would normally be to something where we might get a greater degree of movement across the border. We did that at the time and we set out at the time some thinking around a risk-profiling exercise for different countries. It would be fair to say that Delta has actually changed some of the thinking about that even in the last few weeks. We were looking at a situation where you could stratify countries based on risk, and I think in the Delta environment, we actually have to consider whether, in fact, that's an appropriate thing to do, recognising that all countries, all people coming into the country at this point, have a degree of risk associated with them, and some of the risk protection measures that we've had in place previously, like pre-departure testing potentially three days before travel, in a Delta environment where someone can be picking it up and being infectious within 24 hours—some of those things actually do need to be looked at again. Now, that all plays into a question mark about what our medium to longer-term border settings will be. We haven't set out any new thinking on that. Obviously, at the moment, the focus is on responding to the current outbreak, but I think we will have to look again at some of that thinking around particularly the country risk-profiling, because I think Delta has changed the game.
