Rt Hon JACINDA ARDERN: The official titles for them, not just in New Zealand but abroad, has been advance purchase agreements. Of course, we then go through our own process to make sure that we are giving regulatory approval for their use. So those are arrangements where we're essentially committing to buy, they have to fulfil a number of obligations, we then have obligations on us as to if we accept how much is purchased and paid for etc. A very important point that I'll make to both members in this line of questioning: for us to sufficiently protect New Zealand, we need good, high uptake of vaccines. We have to have the confidence of New Zealanders, and that means making sure that we go through our own regulatory process. Some countries that are rolling out rolled out before clinical trials were complete. That was because people were dying. That is not happening in New Zealand, we are balancing timeliness with security to New Zealanders that they are safe.
