Reliable supply of safe drinking water is vital for human health. Despite this, there is no consistent nationwide spatial dataset of water distribution zones (WDZ) for Aotearoa New Zealand (A-NZ). In this talk, we will outline the development of a nationwide geospatial dataset of WDZ using data compiled from the 67 district and city councils in A-NZ. We will also outline several early use cases for the WDZ dataset.
