Monitoring how water is used for irrigation

May 2018: This is our first of seven audits that will look at how public organisations manage water. For this audit, we looked at how freshwater used for irrigation is tracked and measured. This included looking at how well water meter installation was managed, the quality of data collected from water meters, how the data was used, and whether this was leading to positive changes in the way water is used. We focused on five regional councils and one unitary council from six different regions.
