An emailed statement from the Taranaki District Health Board (TDHB) tonight says the six cases are clearly linked to each other, and there is also a link to the Auckland outbreak which is being further investigated by the health team.
All six people were tested today and returned positive results this evening, with one person admitted to Taranaki Base Hospital this evening.
Interviews are under way this evening and contact tracing will be under way tomorrow.
The other five affected people are currently isolating at home.
The results explain the recent wastewater detections in the town – the most recent was reported on Tuesday, November 9. Any locations of interest will be publicised once determined.
Volzke says it's important people continue to be vigilant.
"The most important thing now is containment, and I strongly encourage anyone with flu-like symptoms or feeling unwell to get tested as soon as possible."
The health board is encouraging anyone in Stratford, or any recent visitors to the town with Covid-19 related symptoms, no matter how mild, to get tested.
Testing will be available in Stratford tomorrow through to Sunday between 10am and 2pm at the War Memorial car park. Testing is also available at Taranaki Base Hospital and Hawera Hospital.
The vaccine hubs are open in New Plymouth and Hāwera on Saturday and Sunday and there are several pop-up clinics in the community. For a full list see the TDHB website.
