We now have been a good distance from the goal degree of participation, however it’s not too late so as to add guide entries into the app to assist pace up the method now as we attempt to get the unfold beneath management.
Pace of contact tracing is important
On the constructive facet, about 1.5 million units are utilizing the Bluetooth Tracing operate, which equates to only beneath 40% of all adults.

When the federal government is making the choice on whether or not to lock the nation down or not, one of many key items of data is whether or not they have faith they may isolate the precise folks rapidly sufficient.
If we don’t have sufficient contact tracing data, we’ve got little alternative however to isolate everybody by means of a lockdown. It’s not the one issue that performs into that call, however it is a crucial one.
The NZ COVID Tracer app is designed to help contact tracing efforts, by making it simple for people to maintain observe of the place they’ve been and who they’ve been close to, whether or not that’s by means of scanning QR codes, including guide entries, or turning Bluetooth Tracing on.
