Gisborne region

Groundwater Zone: Greater Waipaoa Groundwater

The most productive aquifer systems in the region are the complex of aquifers in the Poverty Bay Flats (Greater Waipaoa). These all receive recharge from the Waipaoa River with various degrees of hydraulic connection. The Poverty Bay aquifers are divided into the deep aquifers and the shallow aquifers.

The deep aquifers include the Matokitoki and Makauri Aquifers, both of which are probably confined aquifers and in decline. The shallow aquifers include those strongly linked to the Waipaoa River - the Waipaoa Gravels and the Shallow Fluvial Aquifer, and the unconfined coastal Te Hapara Sands Aquifer. Because of the strong hydraulic link with the Waipaoa River, both the Waipaoa Gravels and Shallow Fluvial Aquifer need to be managed as part of the overall Waipaoa River system. To date they have been managedas separate resources with limited consideration as to their interconnectedness.

Water Use
Groundwater in this zone

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

    Groundwater in this zone

    Accurately estimating the total amount of water available in a groundwater management zone is not currently possible. Regional Councils are working with the Ministry for the Environment on the best way to calculate this figure. We will include these figures on LAWA when they become available. In the meantime, for more information about a particular groundwater management zone, contact your regional council.

    The table above shows the amount of water that is available for use compared to the amount that has been consented. 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.

    Gisborne District Council is currently preparing its first Freshwater plan. Gisborne District Council has not previously held a Regional Plan which addresses the management of freshwater.  This section will be updated when allocation figures are available.

    The above table shows the proportion of water consented for irrigation, industrial, stock, town supply and other. It excludes hydro electricity. In this region/management zone {{hydroUsage.totalVolume}} m3/year is consented for hydro-electricity and makes up {{hydroUsage.percentageConsented}}% of the total water volume consented for this region/management zone
