Two Waitematā DHB health workers are in self-isolation after testing positive for Covid-19.
However, a spokesman for the DHB said both cases are believed to be linked to the Mt Roskill sub-cluster and they did not contract the virus while at work.
One of the staff members was on leave when they tested positive, while the other does not work with patients.
A total of 17 staff were stood down early last week after the two healthcare workers tested positive in late August, but they had all tested negative.
The cases come after confirmation two girls aged between 10 and 14 years old were the latest confirmed cases of Covid-19 in New Zealand.
