Director-General of Health Ashley Bloomfield told a press conference that 85 new confirmed and probable cases were reported in the last 24 hours, which include 76 confirmed and nine probable cases.
He said 37 people have recovered, and eight people are in hospital.
More than 12,000 COVID-19 tests have been completed, with more facilities set up around the country, Bloomfield said.
Overseas travel is still the main reason for new infections, but there's evidence of community transmission, he added.
