Groundwater Zone: Central Plains Groundwater Zone

The Central Plains groundwater zone contains 26,256 hectares, with its eastern boundary following the allurvial terrace on the floodplain of the Oreti River.

The zone is drained by numerous first and second-order streams of the Bog Burn and Terrace Creek catchment. Groundwater quality is generally good, although there are "hot spot" areas where nitrate values are particularly high and are often measured above the drinking water standard. Recharge to the Central Plains groundwater zone is predominantly from rainfall recharge with some infiltration of runoff along the lower slopes of the Taringatura Hills.

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.

    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
