Waikaka surprise!
Along with being national Roadworker of the Week, Marlon and his crew (see below) recently discovered waikaka (mudfish) at the Huapai to Waimauku construction site on SH16. The crew moved swiftly when they spotted movement in the pool of water close by to where they were installing silt fencing.
“I was working near a pool of standing (still) water and saw a movement.” says Marlon. “Since I also discovered some eels on the last site I was working on near Panmure Basin, I knew what to do. We had to stop work!”
The crew quickly stopped fencing, so the fish weren’t disturbed. An ecologist was called in to do an investigation of the wetland drains and prepare a fish management plan.
The fish were found to be black mudfish (neochanna diversus), known as waikaka in te reo Māori. Waikaka are an uncommon native fish listed as ‘at-risk declining’ on the New Zealand Threat Classification. Within the Auckland Region there are only 3 known populations. Any effects on one of these populations can be significant to the species.
A total of 11 waikaka were found by the ecologist at the site and were relocated to a safe habitat. We are very grateful to Marlon and his crew for having sharp eyes and halting their work before these taonga were lost.
