"I'm sure there are people who were hesitant but now realise, Covid is on our doorstep. And we know the best protection is the vaccine. So I do hope this will be a wake-up call."
Napier mayor Kirsten Wise echoed the call for people to turn out and get tested if they had any cold or flu symptoms.
Wise said there was a sense in Hawke's Bay that Covid-19 was bound to reach the area eventually, and she hoped the news would help drive-up vaccination coverage.
She and others in the region would be eagerly awaiting any update from health authorities on whether the wastewater tests are likely to indicate community spread of the virus.
The tests were taken between Monday and Wednesday in Napier and Gisborne, with the positive results being confirmed yesterday afternoon.
There are no MIQ facilities, or known Covid-19 cases self-isolating, in Napier or Gisborne.
The Ministry of Health says the positive tests could be from recently recovered cases returning to the region from MIQ who are shedding the virus, visitors to the region, or undetected cases in the community.
Anyone with even very mild symptoms is being asked to get tested, even if they are vaccinated.
Tairāwhiti has the lowest vaccination rate of any DHB in the country, with 65 per cent of the eligible population fully vaccinated, and 80 per cent with one dose.
For eligible Māori, only 52 per cent are double dosed and 70 per cent have had one dose.
In Hawke's Bay DHB, 85 per cent of eligible residents have had their first dose and 72 per cent are fully vaccinated.
Government-funded science research group ESR will carry out further wastewater testing samples in coming days, with results expected early next week.
