A fresh warning has been issued for Kiwi travellers to New South Wales and Queensland after two infected people from Melbourne breached the city's lockdown.
The case of two Melburnians who breached lockdown and travelled to Queensland has also sparked a new warning for Kiwis.
The Ministry of Health is asking anyone in New Zealand who was in the New South Wales towns of Dubbo, Forbes, Gillenbah and Moree between June 1 and 4, and in Queensland through Toowoomba, Caloundra, Buddina and Baringa between June 5 and 8 to check the locations of interest at the specified times.
Anyone at these locations of interest at the specified times should call Healthline on 0800 358 5453, get tested and self-isolate until they return a negative result, the ministry said.
Those who were at a location of interest at the specified times also cannot not travel to New Zealand within 14 days of the exposure event.
The Ministry of Health said there would be an update on quarantine-free travel later today with lockdown restrictions in Melbourne and wider Victoria set to ease tomorrow.
There is one new case of Covid-19 in this country in managed isolation to report today and none in the community.
Today's new case travelled via Singapore and was detected on day 3 testing.
There were two new cases of Covid yesterday and one person with Covid is being treated at Middlemore Hospital after being transferred from the Jet Park Hotel MIQ facility overnight on Monday.
Meanwhile, three people from Melbourne are in managed isolation at their own expense after misleading officials about where they were travelling from.
The group travelled from Australia to New Zealand via Sydney and failed to declare they had initially come from Melbourne, Victoria.
It is understood they planned to attend a funeral while in this country.
While New Zealand currently has quarantine-free travel with Australia, the arrangement with Melbourne has been paused while the state battles with a growing number of Covid community cases.
Meanwhile Queensland has confirmed two Covid-19 cases after it was revealed a Melbourne case breached lockdown restrictions to go on a road trip across two other states.
One of the cases, a 44-year-old woman who travelled from Melbourne, was confirmed yesterday, with her husband now also testing positive.
The woman and her partner left Victoria on June 1, four days after a statewide lockdown had come into force.
The pair travelled by car through regional NSW and into Queensland, stopping at multiple venues along the way.
Restrictions are currently in place for anyone from Victoria wanting to travel to other parts of Australia.
Despite this, Queensland recorded a case of Covid-19 in the community yesterday, with contact tracing and testing underway after it emerged a Melbourne woman travelled to the state.
New Zealand's director general of health Ashley Bloomfield said yesterday that relevant border agencies would review processes, even though it appeared this was the result of "disappointing actions" from the three people concerned.
They trio tested negative for Covid-19 and their three-day test is due today.
It is unclear at this stage whether they will face any charges in either New Zealand or Australia after breaching both countries' rules.
