Water quality results for popular rivers and beaches in the district.
We have a large number of popular rivers and beaches in Kāpiti. This page outlines the water quality results for rivers and beaches in our district, and also provides guidance for swimming this summer.
How we monitor water quality
We regularly monitor our beaches and rivers in partnership with Greater Wellington Regional Council. The cleanliness of the water is generally safe for swimming and other water-based recreational activities.
Monitoring results are posted on the Greater Wellington website and their interactive map is the best way to check if the water quality at your favourite swimming spot is safe to swim.
Summer advice for swimmers
Earlier this year our test results showed fluctuating levels of bacteria, which at times were higher than usual.
This happens when there hasn't been enough heavy or constant rain to flush out the streams and stormwater channels of rotted vegetation, and other debris which contains bacteria.
This means there’s an increased risk of getting sick with things like tummy bugs if you swim near stream and river mouths at the beach, particularly for the very young, old or vulnerable groups.
Our advice is to keep an eye on the water when you're in our near our waterways, particularly around river and stream mouths at the beach or anywhere where the water looks murky or there’s a lot of debris.. Greater Wellington has the latest monitoring information in its GW interactive map, so you can see anytime where you might need to take extra care.
Advice for swimmers:

If toxic algae reaches harmful levels for humans in any of our monitored recreational water sites, we’ll release public notifications to let everyone know.
It’s normal to expect some degree of blue green algae in the Waikanae River (from SH1 to the river mouth) and in the Ōtaki River during warmer months and sometimes even during mild winters.
There’s always a risk of harm to your dog if you let it swim or scavenge in the lower reaches of our rivers and streams, because algal blooms and dislodged algal mats can occur along the river at any time.
