Understanding our variable and changing climate is critical for managing resources and reducing risks.

  • Otago

    The climate of Otago is perhaps the most diverse of any region in New Zealand.
  • PARTneR (Pacific Risk Tool for Resilience)

    Research Project
    Understanding how hazards impact people and the environment provides the foundation for informed decision making for a resilient Pacific.

    Research Project
    Developing probabilistic scenarios of expected future regional climate changes.
  • Average soil moisture deficit onset and termination maps

    Maps of the average first and last dates of soil moisture deficit are shown here.
  • Southland

    Southland is both the most southerly and most westerly part of New Zealand and generally is the first to be influenced by weather systems moving onto the country from the west or south.
