About 30,000 more people have downloaded the NZ Covid Tracer app, meaning there's been a total of about 354,000 registrations.
The Ministry of Health continued to encourage Kiwis to download the app, saying it would help to identify, trace, test and isolate any cases of Covid-19.
The faster we can do these steps the less likely it is the virus can spread in our communities."
It said personal information and contact details provided through the app would only be used to get in touch if someone is identified as a close contact of a Covid-19 case and location information is not shared with contact tracers unless someone chooses to do so.
"In either case, the personal information shared with the Ministry is held for public health purposes only and will never be used for enforcement."
