Te Maru o Ngāti Rangiwewehi has taken on a project to repopulate Hamurana Springs with a native species known as the kōaro.
However, in recent times, the kōaro, offspring of the freshwater whitebait, has declined in numbers and fears of its extinction have prompted the push to repopulate the Rotorua region.
Hamurana Springs will become a breeding ground for a species native to the Central North Island
Kōaro or kōkopu are native species from the whitebait family and flower in the Hamurana Springs area, but trout and birds pose a threat to their survival which is why Fish and Game became involved in the project.
The establishment of this weir and the relocation of trout from the upper streams of Hamurana were one of the first steps Ngāti Rangiwewehi took in order to repopulate the area with kōaro.
In the future, Ngāti Rangiwewehi hopes to conduct more research around kōaro focusing on their migration process.
