Swimming in Hawke's BayTe kounga kaukau ki Te Matau-a-Māui

Our science team monitors the water quality at popular swim spots over summer so you can check if it's safe to swim where you like to go. Our results go to the national website so you can see if it's 'good to go' wherever you are in NZ. You can also find out about toxic algae.

Can I swim here?

Every Monday, from 1 November to 31 March, we check 38 beach and river sites all over Hawke's Bay, updating the results on this page by mid-week.

On this page you can find whether it's 'good to go' at popular spots in Hawke's Bay. For more detailed information and facilities about each swimming spot, click here, or on any site to go to the LAWA website.

Reminder about swimming after rain

Heavy rain flushes contaminants from urban and rural land into waterways and we advise you not to swim for 2 – 3 days after heavy or prolonged rain – even at sites that generally have good water quality. Check that the water is clean and clear before taking a dip too.

Rule of Toes!​

If it's been raining heavily, our best advice is to stay out of the water for 3 days. A handy guide is - if you can't see your toes when standing knee-deep in water, then water quality is not the best for a swim.

Clive River, Waipuka Stream and Puhokio Stream are generally less suitable for swimming or recreational use, due to higher potential bacteria levels. The Clive River and Puhokio stream are sampled fortnightly as they have permanent signs up warning of the health risks. the Regional Council, community groups and landowners are working to improve water quality in these places.​​

Toxic algae - Phormidium

Is it safe for me to go to the river today?

The District Health Board will put up signs at sites at where toxic algae has the potential to be a risk to human health This information is also relevant for dog health for which the Regional Council is responsible. Conditions can change quickly so for information on the current status of these sites and many other locations see the information below. This also features advise for dog owners in and near rivers.

Phormidium is a potentially toxic algae that can be a risk to human and dog health. It is found in rivers all year round but presents a risk to humans and dogs during the hotter months of the year. Because the risk of finding it is low but the potential impact of eating it is high for an animal or child, we’ve created this dashboard to give you information to make the best decision for yourself, your family, and pets.

Tukituki summer monitoring

We monitor the Tukituki catchment once a week during November to May, which has historically been a common place for Phormidium. The District Health Board are responsible for warning signage, and updates are posted on the Regional Council and the DHB’s Facebook pages.

Current results from the Tukituki programme

While some of the highest levels of toxic algae have been found in the Tukituki catchment, it can grow in other rivers in the region, so always keep a look out, particularly in stony bottomed rivers.

Toxic algae does not always produce toxins but we recommend that humans and dogs avoid physical contact. There are 3 possible pathways for the toxins:

1. Ingestion of the algae itself. This is the greatest risk, some dogs are attracted to rotting mats that are out of the water. While the chances of illness are not high, the consequences of ingestion can be severe as even the smallest amount of black mat algae has the potential to cause severe illness or death.
2. Skin contact with toxic algae. Some humans can come out in rash if they make contact with bare skin, and there is a theoretical risk of a young child transferring the toxins to their mouths if they handle it.
3. From river water. It is thought to be rare for animal and humans to get sick from toxins in the water. However, national guidance suggests that risk increases when coverage of the river bed is over 50% in the wetted area i.e. Red alert.
