Hon CHRIS HIPKINS (Minister for COVID-19 Response): I would say to judge the system based on its results in the current outbreak. So if we look at the overall number of close contacts that have been identified, recognising that we are differentiating between the closest contacts and other close contacts, we're talking about nearly 32,000 identified so far. Now, that's over a 14-day period, so that is well more than the 1,000 a day that some of those earlier reports were identifying we needed the capacity to be able to contact trace.
