Three additional locations of interest have been revealed after another border worker tested positive for COVID-19 at the weekend.
The latest infection - known as case C - was reported on Sunday. They tested positive for COVID after contact with case B.
Both cases are managed isolation workers at Auckland's Grand Millennium facility.
People who visited the below locations are being asked by the Ministry of Health to monitor symptoms for 14 days and get tested for COVID-19 if you become unwell.
- Local Barber Mt Roskill south, April 7 (2pm - 4pm)
- Terminus Dairy, March 29 and 31, April 1, 6 and 7
- Funtech, Queen St - March 29 (5:20pm - 6:25pm)
The three above locations of interest are in addition to the four locations already announced on Sunday.
Prime Minister Jacinda Ardern was earlier unable to say if case C had been vaccinated against COVID-19. The Ministry of Health revealed last week case B hadn't had the jab because they missed two scheduled vaccination appointments due to "personal reasons" - but gave no further explanation.
"So far, that's not something that I have all of the full details around - so I'm going to let [the Ministry of] Health put that out," Ardern said.
The deadline is nearing for managed isolation and quarantine workers to get the jab - the end of April - or people risk being moved on to other jobs, said Ardern.
Ministry of Health officials say 90 percent of border workers have been vaccinated but are unable to say how many border workers there are due to its "continuous" recruitment process.
Director-General of Health Ashley Bloomfield will provide further details on the latest case at 1pm.
