Recreational Water Quality

Welcome to the Hawke's Bay Regional Council's page about recreational water quality. During summer (November to March), Council staff test the water quality at popular coastal and river spots where people enjoy swimming and other water sports.

The Regional Council tests water from selected sites for indications of faecal contamination.  Results of the tests are assessed against the national guidelines for water quality set by the Ministries of Environment and Health.  Results are provided to the Public Health Unit which alerts the public of any problems through news media bulletins and signage.

Most of the coastal beaches are good through the summer months and any problems tend to be short lived after heavy rain, with murky water and contamination generally reducing within 3 days. People are advised to stay out of the water for three days after heavy rain when pollutants can be washed into rivers and streams and incidents of ear, eye and skin infections or stomach illness could occur.

Some streams, rivers and coastal lagoons can have longer lasting water quality problems.  Local councils put up warning signs at affected sites and investigate to find the source of the contamination.  The public should check any warning signs at these places before letting children, in particular, swim in the water.

As well as information being available on this website, local people can also check:

  • B 4 U Swim line 24 hrs: (06) 878 1368.
  • Hawke’s Bay District Health Board website (for alerts): www.healthinhawkesbay.co.nz/ under public health alerts.
  • Signage at locations with regular water quality problems.

The results currently shown are the latest readings from the 2009/10 summer monitoring, and are available from Thursday of the monitored week.

Category Definitions

Green Mode Indicates there is minimal health risk for recreational activities involving contact with water.
Amber Mode Indicates the health risk for recreational activities involving contact with the water may have increased. This acts as a trigger and councils collect more frequent samples.
Red Mode Indicates that any contact with the water could present a significant risk.
E. coli Escherichia coli; a motile Gram-negative bacillus. Bacteria commonly found in the intestines of humans and other animals, where it usually causes no harm. Some strains can cause severe food poisoning, especially in old people and children.
Enterococci Genus streptococcus (or Enterococcus); Gram-positive cocci. A Streptococcus of a group that occurs naturally in the intestine but causes inflammation and blood infection if introduced elsewhere in the body (e.g. by injury or surgery).
cfu/100mL Colony forming units per 100 millilitres of water.

Suitability Definitions

The Suitability for Recreation Grade provides an indication of the general condition of a beach, and is generated by combining up to 5 years of weekly monitoring results with an assessment of how likely the area is to be contaminated by faecal matter from the surrounding catchment. The risk of a beach or river being unsafe for swimming increases as the grading shifts from Very Good to Very Poor. Click on the grade to view the definition and recommendations for that grade.
