Auckland's Pullman Hotel has now been linked to five community cases of COVID-19 following a new positive test from a recently released returnee in Hamilton.
On Saturday, New Zealand's health ministry announced they'd unearthed a new positive test from a person released on January 30.
The person tested negative for COVID-19 while in mandatory 14-day isolation, and even on February 2 after their release, before producing the positive result.
However, the person has been self-isolating at home since their release, and officials believe the public health risk is low.
"People in and around Hamilton should not be alarmed. We are acting out of an abundance of caution," a Ministry of Health statement read.
"We are not advising any restrictions or cancellation of events."
The person lives with two other people, who have both returned negative test results and are self-isolating.
Despite the new community cases, New Zealand has not had community transmission for more than 10 weeks.
For that reason, the government has not raised alert levels or implemented new restrictions.
