With regard to roll growth: nothing new in this particular debate. As long as I've been around education, it's been a case where schools have hotly contested the Ministry of Education's roll projections for their area. Of course, in some cases where it's more immediate, their grounds for doing so are very good. It is a bit of crystal-ball gazing the further out that you get though, and the ministry use a variety of different sources to make those projects. They'll use census data, obviously, and data from Statistics New Zealand, but they also do use data from local government and that around where extra houses are being built in order to try and forecast where the growth is going to take place. Of course, it's going to be very interesting to see how that shakes down in the next 18 months or so, given that all of those projections will have been affected by COVID-19, because, with the closure of the borders, then obviously our population demographics and the projection around our demographics will have changed as a result of that.
