Hon CHRIS HIPKINS (Minister for COVID-19 Response): There hasn't been a change to our appetite for risk, if you like. We're still pursuing an elimination strategy. What there is is more confidence in our contact tracing systems. We have seen other examples over the last six months where we've dealt very successfully with cases without the need to escalate alert levels. There were some additional factors around this one—including not knowing the source and, more latterly, in terms of the second lockdown, there being some undisclosed contacts, which meant that there were a greater number of cases than would have otherwise been the case—that made this one a little bit different.
