Hon CHRIS HIPKINS: The vaccine roll-out model has continued to be refined as we've understood more about both what we can expect in terms of deliveries, but also how we can make sure that we are rolling out the vaccine in a sustainable way. Work has been undertaken, since the model was first mooted, with district health boards to try and smooth demand during that latter part of the year, so that we don't end up with big peaks and troughs. As a result, the average should be, for a sustained period of time, around 50,000 a day. That doesn't mean that there aren't going to be unders and overs within that. We know, at the moment, we have lower vaccination rates, for example, in the weekends; we tend to reach the peak vaccination rates around the middle of the week. Mondays can often be a bit slower; Fridays are often the best day. So there'll be unders and overs within that, but we will be averaging, for a sustained period of time, 50,000 doses a day, and that is how we will get to the population coverage that we're aiming for.
