Detailed new maps that retrace the steps of the Northland woman who tested positive for COVID-19 have been released.
The 56-year-old used the COVID Tracer app to scan into dozens of locations across several days following her release from MIQ. She travelled around southern Northland and the outskirts of Auckland, but developed COVID-19 symptoms during her travels and later tested positive.
The Ministry of Health released around 30 locations of interest in relation to her on Sunday night. While it says the risk of contracting the virus from these locations is often very low, casual contacts who were at the locations during the relevant timeframes are asked to stay home, get a test, and wait until a negative result comes back.
If people scanned into a location of interest and later received an alert through the COVID Tracer app, it doesn't necessarily mean they've been exposed to the virus, the ministry says.
"If you receive a contact alert, it means you have used the app to check into a location at around the same time as a confirmed or probable case of COVID-19, and that contact tracers consider there may have been a risk of exposure," its website says.
"A contact alert is a simple way of making you aware of this risk. However, you might not have come into close contact with the person, and if you did, it might not have been for long enough to present a significant risk of exposure."
It adds contact tracers will be in touch directly if someone's been identified as having a higher risk of exposure to the virus.
