She was located at a west Auckland house and taken into custody under section 70 of the Health Act, being moved into an MIQ hotel.
A couple celebrating their 17th wedding anniversary were at one of the locations of interest - the Comfort Hotel Flames in Onerahi - the same night as the Covid-19 case.
The pair, who do not want to be named, signed in on the Covid-19 tracer app but say they still haven't been contacted to self-isolate or get a test.
"We got no warning, no nothing; just heard it on the news. I work in healthcare so I have to be extremely careful. To find this out on the news that this person had visited there, where else has she been? It's put everybody into panic mode," the Northland woman said.
"A lot of people got very, very angry and still are. We all knew that Delta would eventually or could eventually get into Northland but how it came up is inexcusable."
Asked to describe the mood of those living in Northland, the woman's partner said Northlanders were "totally pissed off and angry" the Covid-19 case had refused to co-operate with health officials.
"There's a lot of anxiety within the community, not knowing where she has been, who she's been in contact with and also with this other woman coming up as well and not even contacting them to let them know she was there as well."
The couple have since both had Covid-19 tests, with the woman returning a negative result and the man's result still outstanding.
"Most of us are keeping to ourselves, not wanting to go out. It's given me a whole new perspective. Even if we go back to level 2, is it actually going to be safe? It's been an eye-opener to how arrogant and stupid some people can be. It's very thoughtless.
"I feel especially for those in Auckland. They've sacrificed so much for us and these two have just [dumped on them] with no thoughts whatsoever of all the sacrifices they have made for us."
