Seymour DavidDAVID SEYMOUR (Leader—ACT): Thank you Mr Chair. I'd just like to ask the question—two questions actually. First of all what is the Government's current advice on vaccine fade the reducing effectiveness of the Pfizer vaccine over time? There appears to be mounting evidence around the world particularly in Israel who started first that vaccine fade is a real thing. And in light of the Government's current advice what is the Government's plan for purchasing booster vaccines at present? The Minister's insinuated on several occasions that the information that boosters might be necessary is coming from Pfizer who are commercially motivated to sell them. I don't know if that really is his view. He might like to clarify but he certainly suggested it several times. Secondly I just wonder about the Minister's view on contact tracing and whether we're getting value for money there whether it's fit for purpose. A useful way to think about it is: is he pleased with the performance of contact tracing in the current outbreak? It seems to have taken about three weeks to get to a stage where everybody had been traced and tested in the South Island. The Minister might like to argue it's less but that was with only 518 cases—and that in itself doesn't sound too bad by the time you add on 12 days to have your second test or third test—except the Prime Minister said it was necessary to keep the South Island at the alert level restrictions it was at because she didn't know what was out there". So I just wonder how the Minister might reconcile that statement with the belief that contact tracing has been effective; and if he doesn't think it's effective what can be done in this financial year to get contact tracing that is more effective? I notice digital contact tracing continues to play what appears to be and the Minister can correct me if I'm wrong a very minor role in the Government's contact tracing efforts. It seems to be mostly manual and they had to hire a whole lot of people and train them up mid-outbreak in order to make that work as well as it has. 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."
