  • NIWA's Hotspot Watch for 20 March 2019

    Hotspot
    Hotspots are now located across the majority of Northland, Auckland, northern Waikato, and interior Bay of Plenty, as well as central Manawatu-Whanganui and Napier south to Wairarapa. South Island hotspots are now located in a portion of interior Marlborough, eastern Banks Peninsula, and the lower Southland coast.

  • Tracing tsunamis through history

    Weaving whakapapa and science together to trace tsunami through history.
  • Adorable Anemones

    An interactive guide to the shallow water anemones of New Zealand. Version 2.0 (2022) is available for download now!
  • NIWA's Hotspot Watch for 6 March 2019

    Hotspot
    A weekly update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent. Regions experiencing these soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.
  • International climate experts gather in Wellington

    Media release
    Weather and climate experts from around the world are meeting in Wellington next week to discuss the critical need for accurate forecasting to cope with a changing climate.

  • Sedimentation effects

    Research Project
    This programme looks at the impacts of sediment plumes created by disturbance to the seafloor and the discharge of processed waters.
  • Plastic pollution processes in rivers

    Research Project
    Most of the plastic in the ocean originates on land, being carried to the estuaries and coasts by rivers.
  • NIWA's Hotspot Watch for 20 February 2019

    Hotspot
    Areas deemed hotspots now encompass large portions of the entire North Island. Hotspots remain entrenched across the northern tier of the South Island, including across northern Tasman, Nelson, and much of Marlborough.
