Hon CHRIS HIPKINS: The nature of the exposure events that we are dealing with in this case really underscores the importance of people keeping good records of where they have been and when. In particular, the COVID tracer app provides a very powerful tool when people use it. If people have been scanning into those locations of interest, they will have received push notifications identifying that they are more at risk and telling them what we need them to do. That only works if people scan in regularly, so I'd encourage people to do that. I'd also reinforce the basic public health measure that we have been reinforcing since our COVID response began, and it should apply at any time, which is: if you are sick, please stay home; don't go to school or to work or to socialise; and if you've got cold- or flu-like symptoms or aches and pains, call your doctor or call Healthline and ask about being tested. This will help to keep yourself and others safe.
