Hon CHRIS HIPKINS: First of all, I think it's important to note that Delta is still a relatively new variant, but our overall level of preparedness for a COVID-19 outbreak, regardless of Delta or not, has continued to improve. That's included looking at things like oxygen supplies, dealing with some of the capital investment required to ensure better oxygen supplies in our hospitals, and it's included things like making sure we've got more ventilators available. I think, from memory, about double the number of ventilators are available now compared to when the global pandemic began. Ongoing work has taken place. There is, of course, and we should all acknowledge this—there continues to be a workforce constraint around our ability to respond to COVID-19. We are asking a lot of our health workforce. We have been for the last year and a half, and I think all New Zealanders are very grateful for their contribution.
