There is one new case of Covid-19 in managed isolation, the Ministry of Health says.
Health officials have also uncovered a historical case - someone who arrived in February from India at the end of February but was only found to have the disease when tested as part of a job application.
"It's important to reiterate that historical cases are not considered to be infectious," the ministry said.
Meanwhile, investigations are continuing into cases at MIQ facilities at the Grand Mercure and Grand Millennium hotels.
Health officials said yesterday the results from genome sequencing showed a link between two infected returnees at Auckland's Grand Mercure MIQ facility.
