Hon CHRIS HIPKINS: As I've indicated to the member before, we made a conscious decision to switch our vaccination campaign earlier in the year from using a portfolio of vaccines to using a predominantly Pfizer campaign. That did mean that the overall balance of vaccinations required in the second half of the year increased. In terms of the overall scale up, we have been taking our time to make sure that we are getting this right. We have a far lower wastage rate to other countries that we're being compared to. The other point that I would make is we are continuing to operate our health system in terms of its business-as-usual practices. Some of those other countries that have a much higher rate of vaccination are able to do that because their health system stopped doing anything else.
