Hon CHRIS HIPKINS (Minister for COVID-19 Response): Ultimately, the issue that the member refers to—there are two. One is cohorting and the other is a better understanding of the physical spaces that we have on offer. There are some facilities where we're not able to us every room that they have because of our understanding of how the ventilation systems work, for example. It's a small number. We're not talking hundreds of rooms, but there are some rooms that we're not using because of the ventilation concerns that exist around them. But, ultimately, cohorting is the thing that has the biggest inefficiency.
