There are no new cases of the coronavirus in the community and five in managed isolation and quarantine facilities.
The Ministry of Health (MOH) said one previously reported case has now recovered, while another previously reported case has now been reclassified as 'under investigation.'
Three of the new cases flew on a direct flight from Fiji to Auckland on 12 July, one case flew to Auckland from Brazil via Qatar on 9 July and one flew to Hamilton from the UK via Singapore on 13 July.
The number of active cases in New Zealand is now 45.
Just under half of all active cases in the country are of the more infectious Delta variant.
Figures from the Ministry of Health show 19 of the 42 cases currently in managed isolation are infected with the strain first discovered in India.
The numbers do not include the five new cases announced today.
Statistics also show Wellington's dual-use isolation and quarantine facility, the Grand Mercure hotel, is currently dealing with the most active cases it has ever had.
Fifteen cases - all crew from the Viking Bay - are staying at the 5-star hotel.
Viking Bay update
Four crew members remain onboard the Viking Bay fishing vessel at Queens Wharf in Wellington and are continuing to receive Covid-19 testing as per the normal sequence for close contacts of a case.
These crew members have had their day 0 test and will be having their day 3 test today.
The remaining 16 crew members are also undertaking scheduled Covid-19 testing while in a Wellington quarantine facility onshore.
The crew member who was transferred to the onshore quarantine facility on Tuesday night after becoming unwell, has now returned a second negative test.
Playa Zahara update
Earlier today, the MOH confirmed 16 of the 18 crew on the Spanish-flagged shipping vessel Playa Zahara had tested positive for Covid-19. But these are not being counted in today's Covid-19 figures, the ministry said.
After the crew had Covid-19 tests, the ship again departed from Port Taranaki and is now on its way to Lyttelton and its time of arrival tomorrow is still being finalised.
Whole genome sequencing is underway.
In a statement, the ministry said as with the Viking Bay vessel earlier this week, the public health risk from the results was considered to be low.
The total number of Covid-19 tests processed by laboratories to date is 2,380,123.
On Wednesday, 7331 tests were processed across New Zealand.
The ministry said the seven-day rolling average is 6787.
These numbers include the number of tests processed by Waikato Laboratory between 11 June and 14 July, as systems affected by the cyber attack are now restored.
There were 8403 tests completed in Waikato from 11 June to 14 July. This represents around two thirds of the number of tests done since the cyber attack on 17 May. The outstanding test results are expected to be uploaded within the next few weeks.
