Te Aitanga a Mahaki<br />

customary eel fisheries<br />

Scientist Ian Ruru and members <strong>of</strong> his hapu<br />

(Te Whanau a Kai) and iwi (Te Aitanga a<br />

Mahaki) are fast becoming experts on New<br />

Zealand freshwater eels in the lakes and<br />

waterways throughout the Waipaoa River catchment<br />

- and on its rich history <strong>of</strong> pa settlements and<br />

battles.<br />

They have surveyed eels in Lake Repongaere,<br />

Poverty Bay, looking at their size, age and growth<br />

rate, as well as checking past rainfall and river flow<br />

data to see if there were any clues to the recruitment<br />

success or failure <strong>of</strong> juvenile eels. This was all part <strong>of</strong><br />

a research project, funded by MFish, designed to<br />

assess the present status <strong>of</strong> eel stocks within the Te<br />

Aitanga a Mahaki iwi rohe.<br />

“We were very fortunate to have the support <strong>of</strong><br />

the Lake Repongaere owners, who saw the benefit <strong>of</strong><br />

assessing the current state <strong>of</strong> eels in their lake,” says<br />

Ian. The lake has always been an important mahinga<br />

kai for the generations who have lived around it and<br />

its commercial potential has recently been<br />

developed.<br />

The group also undertook a mapping exercise to<br />

assess and prioritise other eel populations within the<br />

rohe. This involved integrating the historical<br />

knowledge <strong>of</strong> Maori elders and customary fishing<br />

experts with a GIS database to identify key customary<br />

fishing areas for possible future assessments.<br />

“Te Aitanga a Mahaki Trust see this as a catalyst to<br />

the development <strong>of</strong> an Eel Management Plan for the<br />

entire Waipaoa River Catchment, as well as<br />

contributing to iwi and hapu research capabilities,”<br />

says Ian, adding that a successful partnership between<br />

Maori elders, landowners, scientists, iwi researchers<br />

and the wider community was an unforeseen but<br />

happy outcome.<br />

Ian counts himself lucky to have worked with Ben<br />

Chisnall, an eel expert from Te Awamutu. They both<br />

enjoy working with iwi and hope to develop a<br />

successful research partnership that provides useful<br />

tools to tangata whenua wishing to rebuild and<br />

enhance their natural resources.<br />

“The vision <strong>of</strong> Te Aitanga a Mahaki and the<br />

communities along the Waipaoa River is to ensure<br />

that the eel resource is managed sustainably and<br />

remains a taonga for our mokopuna,” says Ian. “We<br />

hope to continue the recording and utilising <strong>of</strong> Maori<br />

knowledge alongside scientific information to<br />

improve the understanding <strong>of</strong> cultural values and<br />

improved sustainable management <strong>of</strong> customary eel<br />

fisheries.”<br />
