There is a new popup mass vaccination centre being opened up at Auckland Airport https://www.rnz.co.nz/news/national/449700/country-s-largest-drive-through-vaccination-centre-set-up-at-airport
For anybody who's had an appointment pushed out (expecially your 2nd dose because you don't have full protection until you've had that) it might be worth calling ASAP and seeing if you can get it done there.
I was just looking at the MoH vaccine schedule, I'm not sure how many doses we've actually managed to get done this week with the shutdown, but if we did hit the 246,400 we planned for it'll mean we have 809,000 of them in freezers. I guess the issue right now ramping up is that it seems pretty clear we don't have the capability to do this in Auckland due to staff shortages, but maybe we should be focussing on mass vaccinations elsewhere ASAP.
