There are two new cases of Covid-19 in MIQ and no new cases in the community, the Ministry of Health says.

Since 1 January 2021, there have been 116 historical cases, out of a total of 730 cases, it said.
The seven-day rolling average of new cases detected at the border is four.
The total number of confirmed cases is 2548.
Rio de la Plata update
This morning the vessel Rio de la Plata carrying crew members with Covid-19 left Tauranga. Shipping company Maersk said the ship had received clearance from New Zealand health and port authorities.
The company said members with positive test results were all past the acute phase of Covid-19 infection, but would be kept isolated onboard. Port of Tauranga workers who were identified as having contact with the Rio De Le Plata crew have returned initial negative results, the ministry said.
Additional test results required for some port workers have also come back negative, although six results are pending, it said this afternoon.
"Whole genome sequencing of 11 crew aboard the Rio De La Plata has now been completed by ESR. The results confirm 8 crew are infected with the Delta variant. The samples of the other 3 cases failed to return a result," the ministry said.
"The whole genome sequencing results of the crew are linked to the Queensland pilot, who became infectious after being onboard the ship. ESR's assessment is that the pilot was likely infected from the ship and is consistent with Australia's working hypothesis of the source of infection of the Queensland pilot."
On the Mattina container ship, the ministry said mariners currently in quarantine in Bluff were continuing to recover from Covid-19.
As of this morning, 13 of the original 21 mariners remain on board the vessel, it said.
"Five crew members who returned negative Covid-19 test results, including the captain, have now completed 14 days' managed isolation. A sixth mariner, who has serological evidence of an historical Covid-19 infection, remains in managed isolation in Christchurch.
"Of the 15 mariners who tested Covid-19 positive, three are considered by local public health officials to not yet meet the definition of having recovered."
The ministry said more than 2.29 million doses of the Covid-19 vaccine have been administered to date (to 11.59pm on 10 August).
Of these, 1.44 million are first doses and 848,000 are second doses, it said.
"More than 127,000 Māori have received their first vaccination. Of these, almost 79,000 have also had their second vaccinations.
"Around 86,000 doses have been administered to Pacific people. Of these, more than 53,000 have also received their second doses."
Yesterday, 46,629 vaccine doses were administered. This is a new daily record, the ministry said. That number was made up of 30,805 first doses and 15,824 second doses.
