There are seven new Covid cases in managed isolation facilities to report today.

Four of the returnees travelled from Singapore while the others arrived on a flight from India - via Qatar - on June 29 and United Arab Emirates - via Malaysia - on July 2, respectively.

The Ministry of Health also reported that four people who had previously come down with Covid-19 had since recovered.

Today's case numbers come as Australians from three states and the ACT are able to travel to New Zealand quarantine-free again, with the partial reopening of the travel bubble.

As of this morning, those in Victoria, South Australia, Tasmania and ACT can travel here freely, with evidence of a negative pre-departure test within 72 hours of boarding.

Two previously reported cases that were reclassified as being "under investigation" have since been confirmed to be historical cases.

Since January 1, 80 historical cases out of a 579 cases have been reported.

The number of active cases in New Zealand, as of yesterday, stands at 32. The seven-day rolling average of new cases found at the border is three.

As of yesterday, the total number of confirmed cases of coronavirus in New Zealand is 2395.

Six contacts of Covid-infected man who visited Wellington still being sought

Meanwhile, contact tracing teams continue to hunt six people identified as contacts of an Australian man who visited Wellington between June 19 and June 21 before testing positive for Covid when he returned to Sydney.

The man was later confirmed to be linked to the Bondi Covid cluster and had the highly contagious Delta variant. His partner also tested positive for the same strain later on.

Yesterday's Ministry of Health update said of the 2710 people who were in the Wellington region and identified as contacts of the infected man, 98 per cent had returned a negative Covid result.

That was an increase of 22 negative test results reported since Friday.

A total of 33 people have been granted a clinical exemption and therefore have not been tested, while 21 people did not require any further action, health authorities said.

It is thought those people had since returned overseas.

"The remaining six people are being actively followed up by contact-tracing teams," the statement said.

The ongoing advice for anyone who lives in Wellington or was in the region between Saturday, June 19 and Monday, June 21, is to check the locations of interest page to see if they visited any of the places the Sydney travelled went to.

"People who have been at these locations of interest at the specified time should immediately isolate at their home or accommodation and call Healthline on 0800 358 5453 for advice on testing.

A travel pause for Western Australia, Northern Territory, New South Wales and Queensland remains in place until at least tomorrow, when it will be reviewed by officials.

"Travellers to New Zealand must not have been in Queensland, Northern Territory and Western Australia on or after 10.30pm (NZT) on June 26, 2021.

"They must also not have been in New South Wales on or after 11.59pm (NZT) on June 22."

For people now able to fly to New Zealand from Australia, a negative pre-departure Covid test within 72 hours of departure is required for all passengers boarding flights to come here.
