This dashboard shows information on the data collected by the regional councils for water quality indicators, analysed as state and trend.
-
State
State shows how the median of samples from this site compares to other sites.
This site is a {{siteDescription}} site. Currently showing the state of this site compared to:
-
The state is also represented by comparison to the National Objectives Framework (NOF) in the National Policy Statement for Freshwater Management 2014 for some indicators.
-
Trend
Trend shows how the quality of water is changing over time. Depending on the sampling history duration, five, ten and fifteen year timescales are available:

The Cawthron Institute has worked alongside regional councils to verify the processes and methods used for data collection, laboratory analysis of samples collected and the statistical analysis and interpretation of the results presented.
If all Cawthron ticks are green, then you can trust this data. However, if one or more ticks are orange, then conclusions should be treated with some caution.
For more details on each tick, see our 'Can I Trust This Data?' Factsheet.
All samples were collected using approved field protocols and have been analysed in accredited laboratories. Therefore the data shown here has been collected and analysed following best practice.

The majority of trend calculations for this council are based on monthly data. Sites with more data points generally have greater ‘statistical power’ for trends to be detected. Therefore, any trends shown here are based on best practice in terms of sampling frequency based on Davies-Colley et al. (2012).

What is this graph showing me?
This graph is displaying E. coli concentrations over the selected time period. You can adjust this period by changing the dropdowns. These records form the basis for the state and trend indicators displayed on the dashboard. This data is raw and has not had any methodology applied to it.

What do the icons mean?
The bands for E. coli are as outlined in the NOF for freshwater:
