  • Marine trophic index for the Chatham Rise (1992–2014)

    Ministry for the Environment
    The marine trophic index (MTI) measures the changing abundance and diversity of demersal fish species (living and feeding on or near the seabed) in fishery catches. The Chatham Rise has more than 180 species of fish. It is one of the most productive areas of our exclusive economic zone (EEZ) and an important fishing ground. We calculate the Chatham Rise...

  • Mortality of indigenous tree sp black beech 2002–2014

    Ministry for the Environment
    "The rates of death (mortality) of indigenous tree species vary across New Zealand. Changes in the state of the environment (such as from browsing pests, large-scale weather events, or climate change) may change the rates of mortality of particular tree species. This in turn may alter forest processes. Repeated surveys of the distribution of mortality...

  • Performance of assessed fish stock in relation to the overfishing threshold (2009–15)

    Ministry for the Environment
    Our fish stocks are affected by commercial, customary, and recreational fishing, and environmental pressures (eg ocean temperature, acidity, and productivity). The Ministry for Primary Industries uses three performance measures to assess influences on fish stocks: a soft limit (below which a rebuilding plan is required), a hard limit (below which closing...

  • New Zealand's greenhouse gas emissions (1990–2013)

    Ministry for the Environment
    Our greenhouse gas (GHG) emissions are small compared with those of other developed nations, but we have committed to being part of the global response to climate change. New Zealand's greenhouse gas inventory is an annual report on all of the country’s human-induced GHG emissions and removals of GHG emissions. The inventory is produced as part of our...

  • PM10 composed of sea salt and soil

    Ministry for the Environment
    We measure the annual concentrations and proportions of natural and anthropogenic particulate matter 10 micrometres or less in diameter (PM10). PM10 in the air comprises solid particles and liquid droplets from both natural and human-made sources. PM10 occurs naturally, for example, as sea salt, dust (airborne soil), or pollen. Airborne soil particles,...

  • Annual rainfall, 1973

    Ministry for the Environment
    Annual rainfall is the total accumulated rain over one year. Rain is vital for life, including plant growth, drinking water, river ecosystem health, and sanitation. Floods and droughts affect our environment, economy, and recreational opportunities. This dataset shows annual average rainfall across New Zealand for 1973 as part of the data series for years...

  • Long term soil erosion South Island 2012 DEPRECATED

    Ministry for the Environment
    "Long-term soil erosion is the average mass of soil lost per square kilometre per year (tonnes/km2/year) over a period of approximately 10 years. It is extrapolated from long-term measurements of sediment load in rivers. Extrapolation is based on mean annual rainfall, rock type, and land cover. The total sediment in rivers (tonnes/year) for a particular...

  • Annual average sea surface temperature, 2008

    Ministry for the Environment
    The ocean waters surrounding New Zealand vary in temperature from north to south. They interact with heat and moisture in the atmosphere and affect our weather. Long-term changes and short-term variability in sea-surface temperatures can affect marine processes, habitats, and species. Some species may find it hard to survive in changing environmental...

  • Growing season soil moisture deficit, 2013-2014

    Ministry for the Environment
    Soil moisture is important for plant growth. A lack of moisture content over a growing season is a good indicator of drought, which can have social, environmental, and economic impacts. Increasing temperatures and changes in rainfall patterns are expected to increase the frequency and intensity of drought in many regions. Growing season soil moisture...

    Ministry for the Environment
    "Particulate matter 10 micrometres or less in diameter (PM10) in the air comprises solid particles and liquid droplets from both natural and human-made sources. The main sources are burning wood or coal for home heating, and sea spray. PM10 is of particular concern because it is found in high concentrations in some areas. It can damage health and is...

  • River Environment Classification Watershed Waikato (2010) (DEPRECATED)

    Ministry for the Environment
    The New Zealand River Environment Classification (REC) organises information about the physical characteristics of New Zealand's rivers. Individual river sections are mapped according to physical factors such as climate, source of flow for the river water, topography, and geology, and catchment land cover eg, forest, pasture or urban. Sections of river...
