Some of those experts have been calling for better ventilation. I mean, if we can't have these other things, these other protections, which seem to be falling by the wayside as we get back to normal—whatever that is—then at least we can get ventilation sorted. Some of the things that we have been calling for are to improve air quality in schools and ensure this is properly monitored, because relying on open windows in the middle of winter is just not good enough. It makes our tamariki more vulnerable to things like the flu, and other winter-related illnesses as well. It's also important that we ensure that there are ventilation standards in the building code, making sure that they're fit for purpose.
