I'd also just ask about what's happening in Auckland right now. We're told, I think yesterday, that we're down to 33 that aren't connected. It seems that Auckland can't really go out of level 4 until all of the tracing is complete and we can be certain there aren't more cases out there and we've traced to the ends of the chains of transmission. But so far, you know, Aucklanders are going into their fourth week tomorrow, and it's starting to have really mounting costs. So I just wonder, is the Minister satisfied with the value he's getting out of this contact tracing, notwithstanding the efforts of the contact tracers? I don't think anyone is in any way questioning them, but there's no point having the best people in the world working on a system that's not adequate, so I wonder if he could comment on, first of all, vaccine fade. Does the Government believe that it's a real problem; and if so, what's its policy on procuring booster shots? Because we know it's been a very long delay getting, you know, supply, as the Prime Minister told question time—or told the House in question time that the problem with the roll-out has been supply, if we take her at her word on that. We don't want to get in the same problem with booster shots. What's the Minister's satisfaction with contact tracing, given the Prime Minister said we had to keep the South Island at level 3 for further days because she, in her words said, "We just don't know what's out there". Thank you, Mr Chair.
