Director-General of Health Dr Ashley Bloomfield says no new cases of COVID-19 have been recorded in New Zealand.
That means New Zealand's total number of cases is 1503. There are five new recoveries, taking the total to 1447. Only one person is in hospital. No one else had died.
The country only has 35 active cases, according to the Ministry of Health.
On Tuesday, there were 4882 tests processed, taking the overall total to 238,725 tests completed.
The contract tracing app NZ COVID Tracer launched on Tuesday night and Dr Bloomfield said he would encourage people to download it. It allows people to scan QR codes at businesses, recording where they have visited. Fast contact tracing - the process of tracking down and isolating those potentially exposed to someone with the virus - will be pivotal to New Zealand's long-term response to the illness.
"The more people who use it and download it onto their phones the better because it just gives us another way of making sure we have up-to-date contact details and then being able to push a message out to people if they are identified if a possible close contact," he said.
Privacy was a major consideration, Dr Bloomfield said. All information is kept on the individuals' phone unless people to choose to release the data. He guaranteed the data would only be used for the COVID-19 response.
Over 92,000 people have registered on the application already. About 800,000 businesses are being contacted by the Ministry of Business, Innovation and Employment about how to generate a QR code. Approximately 1000 businesses have already created posters with QR codes.
Wrinkles with the application on Android phones are being ironed out.
Dr Bloomfield said the application won't replace on-the-ground work by staff in public health units.
