The government is actively considering mandatory use of the Covid-19 tracer app, NZ Herald reports. More than two million people are registered for the app nationwide, but January’s average scans per day fell to just 465,000. Nevertheless, there was a significant increase in the use of the app when there was an outbreak, according to Covid-19 Response Minister Chris Hipkins. Previously, the government had been hesitant to make the app mandatory due to potential compliance cost, particularly for small businesses. Now, however, it is looking for tools which can be provided to businesses to increase app use.
