Frequently asked questions
A programme managed by the Northland Regional Council, in conjunction with three district councils (Far North, Kaipara and Whangarei) and the Northland District Health Board, to survey the bacterial water quality at a selection of the region's most popular freshwater and coastal swimming sites during the summer months.
A water sample is collected at each site and the sample is analysed in a laboratory to measure the amount of faecal indicator bacteria. Indicator bacteria signify the potential presence of disease-causing pathogens. Water temperature is also recorded whilst on site, along with any other observations, such as the presence of animals in the water or any smell or scum on the water.
Sites are graded according to the concentration of faecal indicator bacteria present in the water – green 'suitable for swimming', orange 'potentially unsuitable for swimming' or red 'unsuitable for swimming'. The results are available on the LAWA website - Northland Region. A paper copy of the weekly results is also available on request from reception at our Water Street office in Whangārei.
If a site is graded as 'unsuitable for swimming', the relevant district council will erect a warning sign next to the site that will remain in place until the water is found to be 'suitable for swimming'.
As a rule of thumb:
- DON'T swim if there are warning signs indicating that the water is unsuitable for swimming.
- AVOID swimming for two to three days after heavy rainfall.
- DON'T swim if the water appears dirty or murky, smells or has scum on the surface.
- BE AWARE of potential contamination nearby or upstream.
Warning signs are the responsibility of the relevant district council:
- Far North Environmental Monitoring Officer – 09 401 5200
- Kaipara Environmental Monitoring Officer – 09 439 3123
- Whangārei Bathing Water Environmental Health Officer – 09 430 4200
If a site is known to have generally good water quality but the occasional 'unsuitable for swimming' result, the warning sign will only be in place until the next 'suitable for swimming' result is recorded. This may be the following week.
If a site is known to have generally poor water quality, the warning sign may remain in place until up to five consecutive 'suitable for swimming' results have been recorded. This may mean that at these sites, a sign remains in place indefinitely.
