New Zealand has two new cases of Covid-19 in managed isolation today.
The Ministry of Health says the first case is "a male teenager who arrived in New Zealand from the USA on July 29".
"He tested positive for Covid-19 as part of routine testing around day 3 of his stay in managed isolation at the Sudima Hotel in Auckland, and has since been transferred to the quarantine facility," they said in a statement.
"The second case is a man in his 20s who arrived in New Zealand from Switzerland via Amsterdam and Seoul on July 20.
"He has been staying at the Sudima Hotel in Christchurch and tested negative around day 3 of his stay, then tested positive at his second routine test."
The Ministry of Health say this case again emphasises the importance of testing returnees in managed isolation twice before they are able to leave the facility.
There are 27 active Covid-19 cases in managed isolation and quarantine facilities. New Zealand's total number of confirmed cases of Covid-19 is 1217.
Laboratories in NZ processed 1692 Covid-19 tests on Sunday, "of which 1259 swabs were taken in the community and 433 swabs were taken in managed isolation or quarantine facilities".
New Zealand's continued success against Covid-19 comes as Australia continues to fight a resurgence of the virus.
Victorian Premier Dan Andrews announced stage-four restrictions - and a state of disaster - for Melbourne on Sunday afternoon, including a curfew from 8pm to 5am for anyone living in the metropolitan area.
Andrews said Sunday "is by far the hardest day" as he announced 671 new cases of Covid-19 and seven deaths along with new unprecedented stage four restriction.
