Te Kūwaha and Māori

Commercial eel fishery in New Zealand began in earnest in the 1960s and expanded rapidly until the early 1970s

NIWA is leading a new six-year research project that seeks to increase our understanding of piharau/kanakana/lamprey, using Mātauranga Māori, social science and biophysical science approaches.

The majority of New Zealanders are able to recall a story about catching eels when they were children.

The need to provide upstream passage facilities for ensuring the long term sustainability of migratory freshwater fish populations is now well recognised.

Tuna, or freshwater eels, are the most widespread freshwater fish in New Zealand. This 'living' educational resource summarises a large amount of scientific and technical literature.

A number of individuals, organisations and hapū have contributed to the development of Ngā Waihotanga Iho.

Traditionally, tangata whenua have collected information about estuaries to monitor resources, such as kaimoana, and to make decisions about conservation measures, such as rähui. Increasingly, tangata whenua are using scientific tools to help monitor their natural resources and Ngä Waihotanga Iho provides a science perspective for talking about environmental issues and concerns related to estuaries.

Through the Te Wai Māori fund Ngā Repo o Maniapoto is a collaborative project between NIWA and the Maniapoto Māori Trust Board (MMTB) Whanake Taiao team that looks to develop an inventory of repo and puna (springs) for the Maniapoto rohe.

New Zealand’s freshwater and estuarine resources provide significant cultural, economic, social, and environmental benefits. Competition for the use of these resources is intensifying, and many rivers, lakes and estuaries are now degraded.

The tools available for restoring kōura to lakes and streams depend on what is causing kōura to decline.

Identifying the factors causing kōura numbers to decline will allow you to determine which restoration tools you need to employ.

Iwi has joined forces with councils and NIWA to restore an estuarine ecosystem to its former health.
