Safeswim water quality monitoring
Safeswim water quality monitoring has finished for the season. For historic data, see the Historic water quality results page
Overall, the water quality in our bathing beaches and lakes is very good and meets New Zealand health guidelines. However, from time to time, water quality problems can arise.
Water safety recommendations
Our Safeswim tests are a snapshot of water quality at a certain time.
To stay safe at any time, we recommend that you always:
- avoid swimming in high-risk areas such as stormwater outfalls and stream mouths
- avoid swimming for up to 48 hours after heavy rain
- obey surf safety guidelines
- look out for organisms that pose a health risk such as jellyfish and toxic sea slugs.
See the below websites for more information:
At some locations we have identified ongoing water quality issues. We do not recommend swimming or recreational water activities at:
- Cox’s Bay
- Meola Reef
- Weymouth Beach
- Little Oneroa Lagoon
- Wairau Outlet.
- Piha Lagoon
- North Piha Lagoon
- Te Henga (Bethells) Lagoons
- Laingholm Beach
- Wood Bay
Some other beaches have a history of excellent water quality, and present a low risk to public health.
For this reason, we do not undertake routine monitoring at:
- Goat Island Marine Reserve, Leigh
- Anchor Bay, Tawharanui Regional Park
- Kendall Bay, Birkenhead
- Cheltenham Beach, Devonport
- Umupuia/Duders Beach
- Lake Wainamu
Reporting water quality issues
The events that are most likely to affect bathing beach water quality are:
- overflows of sewage from the wastewater network
- significant pollution of the stormwater system.
These may carry pollutants and contaminants into our streams, beaches and lakes.
We respond to pollution incidents to protect public and environmental health, and there are processes set up across the region to identify, resolve and manage risks. These include:
- putting up signs
- warning the community of problems, and
- undertaking water quality testing to identify when water quality has improved.
Please report pollution to our Pollution Hotline on 09 377 3107.
