Let's then look at here and now. What we need is uptake and we need use. When we posed that to the Minister around the percentage of New Zealanders who have taken up the app—he avoided it here today. It is likely to be less than 10 percent. The target we need to get at is 60 percent of New Zealanders taking up the app—that will give us maximal traceability. There are benefits the lower we get, but we have to be at 50 to 60 percent, and we are way short of that.
