Hon CHRIS HIPKINS (Minister for COVID-19 Response): Firstly, on the issue of boosters, the technical advisory team that we have reviewing this evidence every day and every week indicate to us, at the moment, the evidence on that is mixed, and so they're monitoring that very closely. So therefore the prudent thing for New Zealand to do in that situation is exactly what we're doing, which is making sure that we're hedging our bets, making sure we're going to have options.
