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

Atmospheric analysis

NIWA has been using advanced scientific instruments to measure atmospheric trace gases and isotopes for over 50 years.

    Mean monthly temperatures (°C)

    These datasets are available in a range of formats.
  • Climate Change Vulnerability Assessment (CCVA)

    Service
    To prepare for changes in climate, our freshwater and oceans decision-makers need information on species vulnerability to climate change.
  • Deidre Cleland

    Scholarships

    Scholarships available to both Masters and undergraduate students in the fields of fisheries science and marine biology.
  • Assessment of crop and tree species growing potential using climate, soil and topographic information

    Research Project
    This project demonstrates how to assess high value alternative land-use options by means of a quantitative analysis of the growing potential of selected niche crops and tree species.
  • Daily climate maps

    These climate maps are updated daily and are based on data from our National Climate Database.
  • Rig shark

    Research Project
    Rig shark is an important inshore commercial fish species in New Zealand, and we need to understand more about their habitats, movements, nursery grounds and vulnerability to human impacts to ensure they are managed sustainably and their productivity is enhanced.

    What are greenhouse gases?

    Greenhouse gases are atmospheric gases that intercept long-wave (mainly infrared) radiation emitted from the Earth's surface.

    Map Sw North

    Education Resource
    Because of its exposure to disturbed weather systems from the Tasman Sea, this climate zone is often quite windy, but has few climate extremes.
  • The impact of El Niño and La Niña on New Zealand's climate

    El Niño accounts for less than 25 percent of the year-to year variance in seasonal rainfall and temperature at most locations in New Zealand.
