Hon CHRIS HIPKINS: The protocols that are being implemented at the moment have a number of different escalation points. At the moment, we're still at the lower level of that, so we're still looking at cases where children have gone to school where their parents may have been tested positive but they have not displayed any symptoms, or where a student has gone to school who has been displaying symptoms, and in that case it would be the school that is closed. For where there was a series of unrelated cases within a community, of course, the number of school closures would depend on the particular circumstances. Where there was evidence of community transmission within a particular geographical area, then closure of schools within that geographical area may be deemed by those officials to be appropriate, and where there was widespread community transmission throughout the country, then those are the circumstances under which a more widespread school closure would be considered.
