This dataset was first added to MfE Data Service on 16 Apr 2018.

Land (whenua) is taonga tuku iho (cultural property, heritage) and of special importance to Māori. As the whakapūmautanga (legacy for the future), whenua provides for cultivation and storage of traditional foods and plants – for customary use and mahinga kai, and helps sustain each generation.

We report only on the available data we have, which cover a subset of Māori land used for primary production activities. The main land use types covered are grassland, forest plantation, bush and scrub, and horticulture.

We report only on the available data we have, which cover a subset of Māori land used for primary production activities. We report on the number of livestock on maori-owned farms for main livestock types (eg farmed beef and dairy cattle, sheep, and deer) for the years 2006-16.

Urban water quality indicators include heavy metals, nutrients, and E.coli. The concentrations of these indicators are compared to the proportion of urban land cover in catchments.

Heavy metals have the ability to accumulate in sediments, shellfish, and other aquatic organisms. Metals can reach toxic levels in organisms making them unsafe to consume and can be toxic to aquatic life. Nutrients can cause excessive algal growth and E.coli has the ability to make people sick while they are swimming if concentrations are high enough. Rivers with poor water quality are rarely suitable for recreation and provide poor habitats for aquatic species.

File contains data analysis of medians and percentiles by site for water quality indicators, and includes the proportion of urban land cover in catchments in Auckland, Wellington and Christchurch over the period 2013–2015.

Urban water quality indicators include heavy metals, nutrients, and E.coli. The concentrations of these indicators are compared to the proportion of urban land cover in catchments.

Zinc and copper are heavy metals that can accumulate in sediments, shellfish, and other aquatic organisms. Metals can reach toxic levels in organisms making them unsafe to eat and can be toxic to aquatic life. Nitrogen and phosphorus are nutrients that can cause excessive algal growth. Ammonical nitrogen and nitrate-nitrogen can be toxic to aquatic life if concentrations in streams are high enough. E.coli is an indicator of disease-causing organisms, which may affect human health and recreational values in streams.

File contains trend analyses by site for water quality indicators in Auckland, Wellington, and Christchurch over the period 2008–15.

This dataset was first added to MfE Data Service on 14 Aug 2019.

This dataset includes three “packages” of information, each with multiple variables. The packages include:

  1. Load – results on mean annual suspended sediment load reported by REC 2 river reach scale for various model scenario variations.
  2. Lakes – results on sediment inflow, outflow, and entrapment in lakes and reservoirs
  3. Coastal – results on sediment inflows, trap efficiency, and sedimentation rates in coastal hydrosystems (estuaries)

For further detail on the modelling methods and discussing results, see Hicks, M., Semademi-Davies, A., Haddadchi, A., Shankar, U., Plew, D. (2019) Updated sediment load estimator for New Zealand. NIWA Client Report No. 2018341CH, prepared for Ministry for the Environment. January 2019. Available online: www.mfe.govt.nz/publications/fresh-water/updated-s...

Note that some portions of this dataset refine and update 2011 modelling on suspended sediment loads across New Zealand, whereas other components, especially the coastal package, report new modelling results.

Statistics reported on include:
- median and median absolute deviation
- percentiles
- trend magnitudes
- statistical test p-values (from the Mann-Kendall trend test, Kruskal-Wallis test for seasonality, and sign-tests and Wilcoxon rank-sum tests for distribution differences).
