Toxic Algae
Ongoing monitoring of toxic algae in the Waipoua River at Colombo Road has confirmed that toxic algae cover is currently low, meaning the warning that has been place since before Christmas has been removed.
There is still a lot of algae in the river at this site, but the composition has changed. Most of the algae is a species of diatom – slimy but harmless. The close-up below shows a rock that is mostly covered by the diatom species – it’s yellowy/green and bumpy in appearance. You can also see a couple of patches of Phormidium or toxic algae. In the other picture you can clearly see small patches of toxic algae (the dark brown/black patches) amongst large patches of diatom growth.
It’s safe to use the river, but please remain cautious if you are taking your dog down there and make sure they don’t eat anything suspicious (even a small amount of toxic algae can be lethal if they eat it).
On the western side of the region, there is a water quality warning in place for Porirua Harbour at the Rowing Club. The latest sample recorded high bacterial counts which means the site is currently unsafe for swimming. This may have been due to recent rain in the area – rainfall flushes contaminants from land into waterways and we advise you not to swim for at least two days after rainfall, even if a site generally has good water quality.

DOC is rolling out a new tool to help figure out what to tackle first when it comes to protecting our threatened species and the things putting them at risk.
Why does this matter? As Nikki Macdonald from The Post points out, we’re a country with around 4,400 threatened species. With limited time and funding, conservation has always meant making tough calls about what gets attention first.
For the first time, DOC has put real numbers around what it would take to do everything needed to properly safeguard our unique natural environment. The new BioInvest tool shows the scale of the challenge: 310,177 actions across 28,007 sites.
Now that we can see the full picture, it brings the big question into focus: how much do we, as Kiwis, truly value protecting nature — and what are we prepared to invest to make it happen?
We hope this brings a smile!
