DAVID SEYMOUR (Leader—ACT): Thank you very much, Mr Chair, and thank you to the Minister for appearing. I've been really interested to listen to the Minister and particularly how candid he's been, saying that there's great uncertainty caused by new variants but the Government is openly considering its options even whether or not elimination is the right option. That's what, I think, I heard him saying. That is quite a big thing for the Minister to say, but it's not unwelcome that he would be laying out different options; some of the options might be unwelcome, but having that more open discussion is very welcome. I think people really have a yearning to understand what New Zealand's options and possible pathways and strategies are. Given this is an Estimates debate, I just wonder what sort of cost-benefit analysis the Government is doing on different options when it thinks about what our future might look like in relation to the border and the level of elimination of COVID-19.
