Kia ora, environmental enthusiasts!
We have some exciting news to share from Dr Dinusha Jayathilake’s EIT Freshwater Ecology Team!
As many of you know, we've been carrying out eDNA testing for the past four years. Over the last couple of years, we've focused our sampling around the Fish & Game ponds and the adjacent Purimu Stream — and something amazing has come up.
We detected Banded kōkopu DNA in the samples!
Now, Banded kōkopu aren’t nationally endangered in Aotearoa— they’re relatively common — but they’re rare along the East Coast, including here in Hawke’s Bay. So, finding evidence of them is a big deal!
After detecting their eDNA in the Fish & Game ponds during our Freshwater Ecology practical sessions in 2024 and 2025, we began to wonder if there might be a resident or migratory group living there. Until now, we only suspected they may visit the outlet pond — we had no idea whether a population existed.
But on the night of 23rd July, that changed!
We went out for a spotlight fish survey with the help of Matthew Brady from DOC, and we found two Banded kōkopu!
This is a fantastic discovery and a huge step forward in understanding the freshwater biodiversity of our region.
A very special thank you goes out to our 2024 and 2025 Freshwater Ecology students for their contributions to eDNA sampling, and to Matthew Brady (DOC), Davey (Fish & Game), Sofia Costa (Level 7 Applied Biodiversity degree student), and Reon Mckeesick for their incredible support and teamwork during the spotlight survey. Your mahi made this moment possible!
We’ll keep you updated as we learn more about these special fish and what their presence means for the Fish & Game ponds and the wider ecosystem.
Stay tuned — and thank you for caring about our waterways!
