The quarantine-free travel zone also gives us the opportunity to reconsider how we use managed isolation. And I think this is important, because the managed isolation system is a very difficult system to run—doing a very important job. It has facilitated the return of over hundreds of thousands of New Zealanders, but there are also risks in running managed isolation facilities, and we have been open about the fact there have been some instances of in-facility transmission that has led to community transmission. It is a risk. And over the course of the response, we've learnt more about the situations in which this has happened—in particular, the evidence for airborne spread of COVID-19 has become more clear over time. That's meant that we have rolled out audits of the ventilation and learnt more about the different facilities that we are using and their suitability as managed isolation facilities. That means, when we think about the capacity in managed isolation that is freed up from having quarantine-free travel with Australia, we can make some decisions that lower the risk profile in managed isolation overall.
