There are no new cases in the community today and four in managed isolation, says the Ministry of Health.
There are now 37 active cases in New Zealand. The seven-day rolling average of new cases detected at the border is two.
Contact tracing teams have identified 4,884 people who have travelled back from Queensland since last Monday and have made contact with 4,681 people, using details from Nau Mai Rā, to provide them with this advice.
The Ministry said contract tracing staff have also identified 2,999 people who returned on managed flights from Victoria between July 25 and 30 and have been required under a section 70 notice to isolate until a negative day 3 test.
Officials are trying to email people based on their entries on the Nau Mai Rā travel declaration form filled out before returning to New Zealand.
Of those 1,113 have so far returned a negative test; 1669 tests are due within the next couple of days; the remainder are currently being assessed for follow-up.
Of the four new cases at the border, three arrived from the UK and one from the United Arab Emirates. The history of the fourth case is still to be determined.
Today's update follows yet another Covid-free day within the community in yesterday's report from the Ministry of Health.
Four new positive cases were, however, found among recent arrivals in managed isolation facilities around the country. That figure is the latest information since the update on Friday.
The first person reported on touched down in Auckland on a flight from the United Arab Emirates, via Malaysia, on July 14.
They are said to be a close contact of a previous case and tested positive on day 15 of their stay, which is thought to have been extended accordingly.
The other traveller who tested positive is a person who arrived from the United Kingdom, via Singapore, on July 17. They tested positive on day 12 of their routine testing.
Authorities said this person remains asymptomatic and there is no evidence of in-facility transmission following investigations to date. This person is currently in managed isolation and quarantine in Auckland.
The third person also travelled from the UK, this time via the UAE and Malaysia, and tested positive on day three of their stay. They are carrying out their stay in quarantine at a facility in Christchurch.
The last person reported on is a traveller who arrived in Auckland on Friday (July 30) and returned a positive Covid-19 test result on day one of routine testing.
Their full travel history is still to be confirmed, the ministry said yesterday. However, the person did travel via Qatar and Australia.
Since January 1, a total of 109 historical cases have now been identified out of a total of 700 cases.
The seven-day rolling average of new cases detected at the border stands at two.
The ministry also announced that a previously reported case, on Thursday, has since been re-classified to "not a case". Another previously reported case from Friday has also been re-classified the same.
Prime Minister Jacinda Ardern's office has advised media that from today, the Ministry of Health's updates will also include the daily vaccination numbers.
"Both of these have been removed from our confirmed cases tally," the ministry said.
The number of active cases in New Zealand now stands at 36 people. The total number of confirmed cases is 2517.
