She says all close contacts identified to date are in isolation and being tested for Covid-19.
The new case was notified after the daily cut-off for reporting and will be included in tomorrow's official Ministry of Health figures.
Campbell says it's important the public know of the isolation rules if they become positive or are a close contact with a positive case.
"Everyone who tests positive for Covid-19 and everyone who lives with them and their close contacts will need to isolate from the community to help stop the spread of the virus.
"If you test positive for Covid-19 your doctor or a health professional will contact you to explain what you need to do. But it's essential you stay at home or your accommodation, unless a health professional tells you otherwise. You will need to isolate for at least 14 days while you recover and be symptom-free for 72 hours, regardless of whether you're vaccinated."
Testing remains available seven days a week in Taranaki and anyone with even mild symptoms should get tested.
Vaccination must now be a priority for everyone, she says.
"With Omicron knocking at our door, we must look at the best ways to protect ourselves, our whānau and our wider community. So please get vaccinated, wear your face masks everywhere, keep sanitising and record your whereabouts by scanning into every venue you visit or work in."
