  • Toolkit development

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

    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.
  • Ngā repo o Maniapoto - Maniapoto wetland inventory

    Research Project
    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.
  • Ngā Kete o te Wānanga: Mātauranga, Science and Freshwater Management

    Research Project
    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.
