Our conversations with Pfizer indicated that they could supply us, this year, enough vaccines to immunise the whole population with that. We agreed with them. We negotiated with them. They indicated that they could supply us the balance of our vaccines in the second half of the year, spread through the second half of the year, and that's when the discussions began. After representations directly from the Prime Minister to the chief executive, they agreed that they could supply us all of our vaccines by October. The conversations have been ongoing ever since then to try and get vaccines into the country as quickly as possible. So it is wrong to say that we haven't been trying to get vaccines into the country as fast as we can right the way through, but we have made the decision that we think the Pfizer vaccine is going to provide the best protection for New Zealand as a country. So that is where our focus has been, in rolling that out and getting it into the country as quickly as we can.
