Mr Green said while the city's overwhelmed sewage system was a potential health threat during flooding, the Covid DNA found in the wastewater was not contagious or a threat at to anyone.
The positive tests results were not related to last week's flooding.
Those tests were done by out by the ESR well before the heavy rain.
ESR would continue to test and health providers would continue to swab people.
Mayor Rehette Stoltz said she was grateful for the high number of people who were vaccinated over the weekend and compared the number favourably to the 912 people vaccinated on Super Saturday last month.
“It was a great effort.”
People had listened to advice and had only turned up for testing if they felt unwell or had flu-like symptoms.
“But we need people to keep it up.”
Hard work was required to keep the vaccination campaign going.
Hauora Tairāwhiti is also advising anyone who has travelled to Auckland recently, is a close contact of a positive case, or has visited a location of interest to get tested for Covid-19 immediately.
Health board chairwoman Kim Ngarimu told The Herald on Friday that a new Tairāwhiti Covid-19 regional co-ordination group aimed to reach the 90 percent vaccination target by December 12.
Ministry of Health projections suggest a Tairāwhiti date of January 12.
Tairāwhiti's most recent released vaccination rate is 80 percent for the first dose and 65 percent for the second.
Mayor Stoltz said “health led the way” and the council would do what it could to assist with the December 12 target.
The Mayor and councillors were holding a Zoom meeting later today to discuss Covid-19 and the Three Waters reform (drinking water, wastewater and stormwater).
Mrs Stoltz said she had been approached to take part in a Zoom discussion on Three Waters with a group of mayors.
Mayors were also working with Local Government New Zealand.
Many local bodies were unhappy with the process of Three Waters reform, she said.
The Government has made Three Waters mandatory, instead of the original opt-in system.
The national media has suggested the group of mayors might take legal action, but Mayor Stoltz said it was more likely they would seek a judicial review.
