Here's another one: we have an NZ COVID Tracer app. Now, I'd be willing to support the Government saying, actually, not only is it mandatory for businesses to display a QR code it's mandatory for visitors to those businesses to use them. Let me just tell you how it works; it's pretty simple. Person A, Matt Doocey, comes in. Now, if there's 50 percent usage, then there's a 50 percent chance that we get him. Now, of course, I know Matt Doocey uses it all the time; he's a good citizen, very good representative of the people of Rangiora.
