Ten new cases of Covid-19 have emerged since Friday, all in managed isolation centers.
In an update shortly after 1 p.m. on Sunday, the Health Ministry said one of these cases was classified as historical, and not contagious.
Eight of the new cases are in Auckland, and one in Christchurch.
The historical case involves a person who traveled from Pakistan via the UAE on September 5. They completed managed isolation and returned two negative test results in September but were recently retested as a pre-travel requirement. The test gives a weak positive, indicating historical infection.
Of the new, potentially contagious cases, two arrived from South Africa via the UAE on Thursday. Both were tested on the first day in New Zealand.
A person from the UK who also traveled through the UAE and arrived on Thursday tested positive as well.
One of the people who have tested positive is from an undetermined country and arrived last Tuesday.
Other people who have tested positive are from Japan, the UK, the United States and the UAE.
“Four cases have now recovered, bringing the total number of active cases in New Zealand to 82,” a health ministry spokesman said.
Since the pandemic broke out, New Zealand has recorded a total of 1,900 cases.
Meanwhile, the first travelers from the UK and US under new pre-departure testing rules began arriving in New Zealand.
New Zealand Customs reported a very high level of compliance with the new rules, the Health Ministry said.
From 11:59 p.m. on Friday, travelers from the United States and United Kingdom must show negative Covid-19 results or sign a medical exemption upon arrival in New Zealand.
In addition, travelers from these two countries must get a Covid-19 test within 24 hours of arriving in managed isolation.
These new arrivals must stay in their room until a negative test result is returned.
Pre-departure testing will soon cover all overseas countries and territories apart from Australia, Antarctica and some Pacific Island nations.
Health authorities hope the new testing rules will better protect New Zealand from Covid-19, including from new and emerging mutant strains of the virus.
