Coastal recreational water quality

Waikato Regional Council monitors a number of popular open coast beaches during the summer months to assess the suitability of the water for recreation such as swimming and surfing. We monitor these beaches weekly from November to March and the results are presented on this page.

We monitor the suitability of the water at these beaches by measuring ‘faecal indicator bacteria(external link)’ (enterococci in coastal waters). The number of bacteria present in the water indicate the likelihood of contracting a disease from many possible pathogens in the water such as bacteria or viruses. Results from the monitoring programme are compared to national guidelines(external link) to determine the suitability for recreation.

The national guidelines(external link) provide trigger levels that allow us to interpret the results by placing them into one of three categories:

Faecal indicator bacteria trigger levels for marine waters as specified by the national guidelines(external link).

Water quality at Waikato beaches is generally high but caution should be taken following heavy rain. Heavy rain flushes contaminants from urban and rural land into waterways, which then make their way to the coast. These contaminants may be present in the water for up to two days (48 hours) after heavy or prolonged rainfall.

We will be working together with District Councils and the Waikato District Health Board to identify any results that may have public health implications and then provide the public with the best quality information.
