Dataset used to develop the "Extreme wind indicator [available at www.stats.govt.nz/indicators/extreme-wind]

This indicator measures the strength of extreme wind and how often extreme wind events (measured as a gust that is extreme for that location) happen at 30 sites across New Zealand from 1972 to 2019, although not all sites start at 1972. We report windiness using the annual average of the daily maximum wind gust. We report wind strength using the annual maximum wind gust. We use the number of days per year with a maximum wind gust in the 99th percentile to report how often extreme wind events occur for a location (on average, the 99th percentile daily maximum wind gust will be exceeded on 3.6 days per year). We also present trends for all three of these measures.

Dataset used to develop the "Wildfire indicator [available at www.stats.govt.nz/indicators/wildfire-risk]

This indicator measures fire danger using the New Zealand Fire Danger Rating at 30 sites around New Zealand from 1997 to 2019, although not all sites start at 1997. We report on the number of days per year with ‘very high and extreme’ (VH+E) fire danger for each of these sites, and trends over time.

Particulate matter (PM) comprises solid and liquid particles in the air. PM10 particles have a diameter less than 10 micrometres. Coarse particles (2.5–10 micrometres) can be inhaled – they generally deposit in the upper airways; fine particles (smaller than 2.5 micrometres) can deposit deep in the lungs where air-gas exchange occurs. Children, the elderly, and people with existing heart or lung issues have a higher risk of health problems from exposure to PM10. These problems include decreased lung function, heart attack, and mortality.
Human-generated PM10 sources include burning wood and coal for home heating, and traffic emissions (eg combustion, tyre and brake wear, and pavement breakdown). Natural sources include sea salt, dust, pollen, and mould spores.

Heavy metals in river waters are an indicator of river water quality. We monitor a subset of rivers and streams in predominantly urban areas in Auckland, Wellington, and Christchurch, and look at how these values are changing over time. This indicator shows:

  • trends in concentrations based on measurements made at monitoring sites during the seven-year period from 2011 to 2017

Heavy metals in river waters are an indicator of river water quality. We monitor a subset of rivers and streams in predominantly urban areas in Auckland, Wellington, and Christchurch, and look at how these values are changing over time. This indicator shows:

  • concentrations of dissolved copper and zinc measured at monitoring sites for the three-year period from 2015 to 2017
  • how these compare to the default guideline values for the protection of 95 percent of species in the Australian and New Zealand guidelines for fresh and marine water quality (ANZG, 2018)

This indicator measures the physical habitat condition of New Zealand waterways. We report on 369 sites across six North Island regions and 90 sites in one South Island region (Southland), identifying the overall state of stream habitat at each site based on at least three years of data between 2013/14 and 2018/19. Ten physical habitat components are measured during the assessment, including bank erosion and the diversity and abundance of fish cover (Clapcott et al, 2019).
