Coasts

NIWA aims to provide the knowledge needed for the sound environmental management of our marine resources.

  • Resources

    Guides and other tools
  • Tidal energy optimisation

    Research Project
    Understanding the complexity of tidal resources in New Zealand’s coastal waters and examining how extracting tidal energy would influence and be influenced by this variability.
  • Estuarine Ecodiagnostics

    Research Project
    Estuaries are highly valuable systems that provide enormous economic and cultural benefits to all kinds of people. However, expanding human populations and urban development around estuaries is increasing contaminant loads, with metals and polycyclic aromatic hydrocarbons (PAHs) accumulating in sediments.
  • Ngā Waihotanga Iho - Iwi estuarine monitoring toolkit

    Research Project
    Ngā Waihotanga Iho, the estuarine monitoring toolkit for Iwi, has been developed to provide tangata whenua with tools to measure environmental changes in their estuaries. While Ngā Waihotanga Iho is based on sound science principles, it is also underpinned by tangata whenua values.
