River, stream, and beach water quality including wastewater overflows
Taranaki Regional Council monitor bacteria levels at popular swimming and fishing sites. The monitored sites in New Plymouth District are shown below (to view all sites in Taranaki visit trc.govt.nz).
The map also shows any wastewater overflows and warnings, and you can find more information about wastewater overflows in the table below the map.
Please note that MPI also issue toxic shellfish warnings, you can view them here.

Sewage Overflow Alerts
Some of the water health warnings are because of wastewater overflows. Please find more information about these in the table below.
Waterway affected | Discharge location | Date of discharge | Waste type | Warning | Comments |
---|---|---|---|---|---|
Mangati Stream and Waiwhakaiho | Mangati Stream and Waiwhakaiho Beach | 1 April 2021 | Sewage |
No shellfish gathering Warning ceases: 29/4/2021 |
High rainfall event causing wastewater overflow from the pump station. |
Bell Block Beach | Mangati Stream | 28 March 2021 | Sewage |
No shellfish gathering No shellfish gathering warning ceases: 25/4/2021 |
Pump station overflow due to a power outage. |
Urenui River | Stormwater outlets onto the mudflats | Unknown | Likely septic tank discharge |
No shellfish gathering and avoid the mudflats Warning ceases: Ongoing |
Testing has found elevated levels of bacteria in the stormwater discharging onto the mudflats. |
Bell Block Beach | Treatment Plant Outfall 1.2km off Waiwhakiho River Mouth | Historical |
No Shellfish Gathering Warning ceases: Ongoing |
Residual levels can accumulate in shellfish under normal wastewater treatment plant operation. Ongoing monitoring of shellfish in progress to confirm if signage can be removed. | |
East and West of the Waiwhakaiho River Mouth | Treatment Plant Outfall 1.2km off Waiwhakiho River Mouth |
Historical |
No Shellfish Gathering Warning ceases: Ongoing |
Residual levels can accumulate in shellfish under normal wastewater treatment plant operation. Ongoing monitoring of shellfish in progress to confirm if signage can be removed. |
The District Councils use Taranaki Regional Council’s monitoring and national health guidelines to determine whether the water quality of a site is suitable for swimming and other water-based recreational activities.
Taranaki Regional Council monitors bacteria that indicate if there is faecal contamination at popular coastal and freshwater spots every summer (November to March), and the data is fed directly to maps on its website. The national guidelines for microbiological water quality categorise recreational bathing sites into a three different 'modes' (green, amber, red) according to the results of faecal indicator bacteria counts.
Please contact us if you see any sign that is damaged or out of date.
To report a pollution incident within Taranaki, call the Taranaki Regional Council immediately. Call 0800 736 222 at any time, 24/7, including public holidays.
If your dog suddenly falls ill after swimming or visiting a river, lake or the coast, take it to the vet and contact Taranaki Regional Council’s pollution hotline 0800 736 222 to advise them of your water quality concerns.
- Diarrhoea
- Vomiting
- Respiratory illnesses, similar to flu-like symptoms
- Skin, eye and ear infections
- Abdominal pain, cramps, and nausea
- Irritation of the skin, eyes, nose, and mouth, which may appear as an itch, redness or dermatitis.
- Toxins can also affect the liver and the nervous system. People at greatest risk of a reaction are children, pregnant women, the elderly, and those with pre-existing medical conditions.
Taranaki District Health Board has a lot of very useful information on what illnesses you can contract from swimming in contaminated water. See the FAQs on the TDHB website
See your GP or ring Healthline on 0800 611 116. Tell them you may have been exposed to contaminated water. Your doctor has been asked to notify the Medical Officer of Health of any people with possible reactions.
No. You should avoid any skin contact with the water and avoid swallowing the water.
No. Eating shellfish from affected areas should be avoided.
There are a number of disease-causing bugs (called pathogens) that can survive in the sea, lakes and rivers for some time. The bugs mainly get into the water through human and animal faeces. When we come into contact with water that has been contaminated we expose ourselves to the bugs and risk getting sick.
Even when beaches, lakes and rivers meet health guidelines, there is still a small health risk when you swim at that spot. It is not possible to say there is zero risk to public health, especially where there are known sources of human and animal faeces near the water.
Pathogens cause disease in humans and animals. There are many different kinds of pathogens. Some of the more widely known are Campylobacter, Salmonella, Giardia, Cryptosporidium and viruses that cause diarrhoea and flu-like symptoms. The pathogens are present in faeces and may enter our waterways through untreated sewage discharges, leaky sewerage pipes, septic tanks, stormwater, rural run-off and from birds.
Cyanobacteria are commonly known as blue-green algae. When algae multiply rapidly we get a “algal bloom”, which occur naturally. Activities, such as taking water from rivers or adding nutrients to waterways, can make things worse.
Cyanobacteria can produce toxins, known as cyanotoxins. The toxins can be a threat to people and animals if present in drinking water, or if people and animals come into contact with the water.
No, wearing a wetsuit or a rash vest will not protect you and could make any reaction worse. The cyanobacteria may accumulate in the collar and cuff areas and rub against your skin. This may cause a strong skin reaction in these areas.
We recommend you do not use sites that have health warning for boating or canoeing. Recreational water safety is a joint initiative between the Taranaki Regional Council, the New Plymouth District Council, the South Taranaki District Council and the Stratford District Council.
Wastewater overflows can sometimes occur when there is a problem with our sewer network. The Council works hard to ensure that the sewer network operates well, however there may be times when an overflow of sewage cannot be prevented and can enter a stream, river or the sea. As these overflows may result in contamination of water and shellfish, we recommend that you do not swim or collect shellfish while there are health warnings in place.
Common causes of wastewater overflows include:
- Broken sewer pipes.
- Blockages caused by fat build up or tree roots in a pipe.
- Power outages.
- Mechanical problems or blockages which cause pump stations to stop.
- High flows through the network due to rain or storm events.
The Council monitors the sewer network so that any overflows can be detected and stopped as quickly as possible.
