Hon CHRIS HIPKINS (Minister for COVID-19 Response): It would very much depend on the facts of each individual case. In every individual case that we've seen regarding COVID-19, since we started this process 18 months ago, every case has been different and every case has required a slightly different response. So I think some of the things that we would look to are: the nature of the contact—was the source of the person contracting the virus known? Those are all things that we've always looked at previously, but the answer to some of those questions might dictate a slightly different response.
