Thousands of people have asked the Ministry of Health for help after having trouble enabling Bluetooth on the Covid-19 tracer app, which at last report had 2,514,708 registered users.
Director-General of Health Dr Ashley Bloomfield said for those who were out and about over last week's anniversary weekend in Auckland and Northland, and this coming Waitangi Day long weekend, it was more important than ever that people kept a record of where they had been.
"We continue to strongly encourage people to continue to scan using the NZ Covid Tracer app and turn on Bluetooth," he said.
"The more we all scan, the safer we'll all be. Scanning helps our contact tracers to quickly find and alert any potential close and casual contacts of people who have tested positive for Covid-19."
However, about 20 per cent of cellphones could not use the Covid Tracer app's Bluetooth function. Android phones needed to be running Android 6 or above, have Google Play Services enabled, and have Bluetooth Low Energy capability, while iPhones must be running iOS 13.5 or above.
