The app is easy to use, but people just don't use it. I continue to use it.
Most people travelling on public transport now have access to a mask, but aren't wearing them, as no longer compulsory, even though the official recommendation is that they should. I continue to wear one. On my Kapiti commute this morning, there were 3 mask wearers in a double carriage of, I'm guessing, about 200+ people.
If (when) Covid returns to NZ, there will be a lot of people pointing fingers, no doubt blaming officials, while refusing to acknowledge their own complacency.
