Meanwhile, two recent cases in Wellington reported on January 8 are linked to recent travel to the Bay of Plenty earlier this week. So far no new cases have arisen since then.
This includes one with a possible link to the Drum & Base festival at Wharepai Domain on January 3.
Anyone who was in Tauranga for the festival is advised to urgently get tested and isolate at home until they receive a negative test.
In the past two days there have been 85 new community cases identified, including 57 in Auckland and seven in the Waikato area, plus 64 at the border, the ministry confirmed.
The ministry is urging anyone with symptoms – no matter how mild – to get tested, even if vaccinated.
"Please stay at home until you return a negative test result. We are also asking people to regularly check the locations of interest as these are regularly updated and to follow the advice provided."
According to the Waikato District Health Board's Facebook message, Covid-19 has been detected in wastewater in Whangamatā.
The Waikato DHB said on Friday that health officials had not been able to link the wastewater detection to a confirmed or recovered case, "meaning there could be an undetected case in the Whangamatā area".
As a precautionary measure, a pop-up Covid-19 testing site is operating at the Whangamatā War Memorial Hall today and on Monday from 10.30am to 2.30pm. The hall is located at 328 Port Rd, Whangamatā.
Covid-19 testing is also available at Whangamatā Medical Centre on Lincoln Rd and people need to phone first to book an appointment.
The DHB said anyone with cold, flu or Covid-19 symptoms should get a test, even if they were vaccinated.
"If you are unsure, a health professional can let you know. Call Healthline for free on 0800 358 5453 or doctor or nurse, or your iwi health provider."
