Hon CHRIS HIPKINS (Minister for COVID-19 Response): We haven't necessarily agreed a final revised set of metrics. We continue to use those metrics as they were identified by Dr Verrall. It's important in the way that they're reported that we differentiate, I guess, between the very early phase of an outbreak and the bit that we're in at the moment, where more regular updates are required that remove from the statistics some of those earlier numbers, because those earlier numbers can be distorting of the overall performance of the system here and now.
