Rt Hon JACINDA ARDERN: The first thing I'd say is that countries of course are working incredibly hard to vaccinate their populations so that they can get normality back in their lives. They are working very hard to get what New Zealanders for the most part already have, so that means that of course when it comes to, not our advanced purchase arrangements, but delivery against them, Australia and New Zealand have very openly acknowledged that the pressures in New Zealand are very different to other countries. People are literally not dying while they wait, so that means delivery has been different. The second point I'd make is our programme is different. We're using a primary vaccination in Pfizer. We will have others available, but that is our primary dose that we're using. The third point I'll make is that we have been making sure, as I said, that we are sequencing our roll-out so that it has a continual upward tick—that we don't open, close, open, close—and so that has been about managing our inventory and the doses we have available on supply.
