On 1 July 2025, NIWA merged with GNS Science to become Earth Sciences New Zealand.

Research

All NIWA research projects

  • Pacific atoll mangrove forests losing ground to sea-level rise

    Research Project
    Mangrove systems on oceanic atolls may lose the race to keep pace with sea-level rise.
  • Climate and Māori Society

    Research Project
    Climate has always been important for Māori. It affects natural environmental systems and resources, influences social-ecological knowledge and practice, shapes community vulnerability and resilience.
  • Reducing COVID-19 transmission through increased ventilation

    Research Project
    Funded by the Ministry of Health, NIWA air quality researchers are carrying out research to understand ventilation behaviour and examine how well spaces used by our most vulnerable populations are, and could be, ventilated.
  • Identifying rip currents using artificial intelligence

    Research Project
    NIWA and Surf Life Saving New Zealand are working together to develop a state-of-the-art, rip current identification tool.
  • Investigating ecological impacts on freshwater insects from LED streetlight conversions

    Research Project
    Little is known what impact artificial streetlights have on flying freshwater insects which are integral to our waterway ecosystems.

    Explainer: Uncertainties in flood risk assessments

    Research Project
    University of Canterbury’s Professor Matthew Wilson, one of the Mā te haumaru ō te wai research team, gives us some insight on uncertainty.weather
  • Cultural Keystone Species

    Research Project
    A four-year research programme focused on the co-management and restoration of our freshwater taonga species.
  • Pacific Risk Tool for Resilience, Phase 2 (PARTneR-2)

    Research Project
    The three-year PARTneR–2 project aims to help countries in the Pacific become more resilient to the impacts of climate-related hazards.
  • River flow forecasting

    Research Project
    NIWA is developing a national river flow forecasting tool for New Zealand that aims to support and strengthen our planning for and response to extreme rainfall events.
  • Pacific Sunrise

    Climate Data for the Environment Services Client (CliDEsc)

    Research Project
    CliDEsc is a web-based content management system and product generator library developed by NIWA in consultation with National Meteorological and Hydrological Services in the Pacific region, and with the Australian Bureau of Meteorology.
  • Freshwater bioremediation using native mussels - focussed on shallow eutrophic lakes

    Research Project
    The project aim was to harness the filter-feeding capacity of native freshwater mussels on rafts to assist in lake restoration.
  • Hauraki Integrated Land-Water Modelling

    Research Project
    The Inner Hauraki Gulf/Tīkapa Moana ecosystem is facing proliferations of algae, de-oxygenation, reduced pH (acidification), reduced water clarity, and muddier sediments arising from historical and future land-derived contaminant inputs.
