Hon CHRIS HIPKINS: Those things are very difficult to measure. In fact, some students continue to learn very successfully using distance learning technology or other means of distance learning. And, in fact, there is evidence to suggest that, for some children, they do slightly better in their academic achievements through distance learning than they do from face-to-face teaching. However, there are significant social benefits, in terms of kids' social development, of them being back on a school site. It is difficult to quantify those things, though. The Ministry of Education, the Education Review Office, the New Zealand Qualifications Authority, and the New Zealand Council for Educational Research have all looked at the impact of the disruption on children's learning last year, where there is some data available, and it found, it would be fair to say, that the overall analysis is variable. Some students did better, and some did worse. But we are, of course, aware that—well, we are committed to getting kids back on to school sites so that they can resume a more regular schooling pattern as soon as it's safe to do that.
