Hon CHRIS HIPKINS: No, what it's a sign of is that people can test positive for COVID-19 long after they have recovered from the virus. That's a well-established fact within the scientific and health community. There will be people in New Zealand who did not get tested during the lockdown who did have COVID-19 during that time, and who recovered. In some cases, people did not seek a test. They did exactly what we suggested, which was they stayed home and they got better. In other cases they may have sought a test and not had one, because—in some cases—I'm aware of people who went to get a test but were put off by the fact that there were long queues outside the testing stations. So there will be people who were positive for COVID-19 previously, who have had the virus, who have subsequently recovered, but who would still test positive if tested today.
