Hon CHRIS HIPKINS (Minister for COVID-19 Response): Yes I can. I can say to all New Zealanders that there are a whole variety of things we ask them to do as precautionary measures in the event that we need to obtain that information, including scanning QR codes if they're in the South Island, for example. One could say that because we're not sending out current push notifications to people in the South Island, they shouldn't scan their QR codes; they'd be wrong if they were making that assertion. Having Bluetooth turned on adds an additional tool to the tool kit, and it doesn't cost people anything. It doesn't mean that they have to do anything extra, other than one thing that takes about 30 seconds to do.
