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

How much water is there in this region?
Rainfall and runoff in this region
Show HideRainfall and runoff
Relative Volume Source Volume Rainfall total:
{{waterAvailable.rainfall }}
Rainfall Total {{waterAvailable.rainfall}} Runoff total:
{{waterAvailable.runoff }}
Runoff to sea {{waterAvailable.runoff}} The table above shows the average amount of rainfall the region 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).

It also shows how much of this water is surface water and how much is groundwater.
Values for water availability have not yet been provided. Greater Wellington Regional Council is in the process (as at June 2015) of notifying a new Regional Plan that will contain proposed allocation limits. When this Plan is notified the proposed limits will be used to update the empty fields.

It excludes hydro electricity. In this region/management zone {{hydroUsage.totalVolume}}/year is consented for hydro-electricity and makes up {{hydroUsage.percentageConsented}}% of the total water volume consented for this region/management zone
