Dr SHANE RETI (National—Whangarei): Thank you. On 9 June, the policy for the border was that people would be coronavirus tested around day three and day 12, and this was discussed in Estimates as well. I want to ask the Minister in the chair, the Hon Chris Hipkins—because I still don't understand—why day three testing is not compulsory. Particularly if we look at the majority of cases from 9 June that have been positive, they've all been day three positive. The majority of positive cases have tested positive at day three. We may have different numbers, but I checked this last week, and that's how I see it, but I'm prepared to hear a different explanation.
