Regional councils collect information about how much water is available and manage resource consents for those wishing to take water from rivers and streams. Use the buttons below to view information on: how much water is available, where it comes from and how its used.

Runoff to sea
{{waterAvailable.runoff}} The table above shows the average amount of rainfall the water management zone receives each year and how much of that flows out to sea. These are approximate figures only.
Total run-off to sea has been estimated by aggregating mean flow statistics from the River Environment Classification (developed by the National Institute of Water and Atmospheric Research).

The ‘Total Consented’ and ‘Total Consented and Measured’ fields are based on percentages of the ‘Total available to Consent’ field. If this field is not populated no data will be displayed. Some consents require actual use to be monitored and this is presented as 'Total measured volume Used' where available.
It is important to note that where the amount available to consent is exceeded in the table above, this does not necessarily mean that over-allocation is occuring, or a significant adverse effect is being caused by existing consents. Greater Wellington Regional Council (GWRC) has adopted interim ‘allocation amounts’ in their Natural Resources Plan which have been set using a conservative default method until fuller community led (Whaitua) limit setting processes can be completed. Resource consents in these catchments were granted in accordance with the policies and rules in place before the interim allocation amounts were set so can continue to operate but no new water can be granted.
Nevertheless, where the amount available to consent is exceeded, it does signal that ecosystem health risks are potentially elevated. This signal of risk is helping communities and GWRC focus attention in such areas to develop a better understanding of the true effects of existing takes. For further context and information about allocation amounts and availability please contact GWRC.
