Hawke's Bay District Health Board's Medical Officer of Health has issued this statement.
A positive COVID-19 wastewater result has been detected in Napier, prompting Hawke's Bay DHB to stand-up surge capacity testing and vaccinations this weekend.
Hawke's Bay District Health Board Medical Officer of Health Dr Bridget Wilson said a wastewater sample carried out by ESR on 3 November had returned a positive result.
"Hawke's Bay does not have any known COVID-19 cases isolating in the region.
"The result could be due to recently recovered cases returning to Hawke's Bay who are still shedding the virus, but who are no longer infectious. However, it's important that we rule out undetected cases in the community by increasing testing."
