  • Protecting people

    Feature story
    Mia Blyth talks to an environmental hazard specialist who feels a very personal connection to his work.
  • Bridging the forecasting gap

    Feature story
    Improvements in data and climate science mean forecasters are able to predict patterns much further ahead and in far greater detail. Melissa Bray looks at what this may mean for farmers.
  • Marine heatwave developing

    Media release
    Coastal waters around Aotearoa New Zealand became unusually warm last month, say NIWA.
  • Climate change experts tour New Zealand’s coastal wetlands

    Media release
    A group of international scientists are visiting some of New Zealand’s most significant coastal wetlands as part of a five-year research project to help the country adapt and prepare for sea-level rise.
  • 2022 off to a searing start

    Media release
    New Zealand’s weather is proving no exception to the record-breaking extremes occurring around the globe.
  • A Hard Rain’s A’Gonna Fall

    Feature story
    Climate change means more intense storm systems are on their way. Science can’t stop it raining, but it can help communities prepare for the worst and plan for the future.
  • Glacier timelines

    Once upon a time, long ago, massive glaciers covered our landscape. As they retreat, they leave piles of sediment and rocks behind called moraines that tell an important story of New Zealand's climate history.
  • Understanding why our giant glaciers disappeared in the past gives clues to the future

    Media release
    An international team of climate scientists is working in North Canterbury to try to understand the reasons why giant glaciers disappeared thousands of years ago.
  • Glaciers continue to shrink this year, says NIWA

    Media release
    The annual end-of-summer snowline survey of more than 50 South Island glaciers has revealed continued loss of snow and ice. Last week, scientists from NIWA, Victoria University of Wellington, and Department of Conservation took thousands of aerial photographs of glaciers. Some of them are used to build 3D models that track ice volume changes.
  • Mean heat: Marine heatwaves to get longer and hotter by 2100

    Media release
    New research from the Deep South Challenge: Changing with our Climate and NIWA shows that New Zealand could experience very long and “very severe” marine heatwaves by the end of the century.
