Swimming warning to remain in place at Wairoa River - 31 January 2018
Swimming warnings remain in place at Wairoa River where an investigation is ongoing by Hawke’s Bay Regional Council and Hawke’s Bay District Health Board into recent high levels of E.coli contamination.
Hawke’s Bay District Health Board Medical Officer of Health, Dr Nicholas Jones, said that despite one sampling result showing levels had dropped back below guideline level warnings, people should still avoid swimming in the river.
“Our investigation is continuing, and the overall trend of Wairoa River is that it is continually graded as very poor and therefore is not recommended as a site for swimming and other recreation.
“Faecal sourcing testing, which forms part of the joint investigation into the likely cause of contamination in the water, has been carried out and samples were currently being processed by a lab.”

Swimming warning to remain in place at Wairoa River - 24 January 2018
Swimming restrictions remain in place at Wairoa River following water sample results this morning confirming high E.coli levels remain in the river – four times above safe swimming guidelines. (see footnote for reading).
Hawke’s Bay District Health Board Medical Officer of Health, Dr Nicholas Jones, said the DHB was continuing to work with Wairoa District Council and Hawke’s Bay Regional Council to understand what might be contributing to the elevated levels.
“Despite yesterday’s weather storm, we know that these readings are not rainfall related so we are working with both councils to further investigate the cause,” said Dr Jones.
“Regular water sampling and monitoring will continue and the regional council will also be using a faecal source tracking tool to investigate the likely source, which will further help to narrow our investigation.”
Warning signage erected by Wairoa District Council against swimming in the river would remain in place.
Dr Jones urged people to take notice of the warnings and avoid swimming in the river until further notice.
Note: (Reading was 1040). Readings should be less than 260 E.coli per 100ml.
