Rt Hon JACINDA ARDERN: I think, just to be fair to our health service, of course it is fair to say that the immunised—we have not had a national well-functioning immunisation register for years. We have that now, and that is an absolutely fantastic legacy project that we now have to make sure we improve all our vaccinations. On the booking system, of course DHBs and our health sector have their own booking systems. We've seen the need for something nationally. We've put in place that solution. But keep in mind we have run immunisation programmes nationally before quite successfully without that in place, but this is a sensible option to enable a smoother roll-out later on down the track.
