Matemateaonga South

The Matemateāonga Formation comprises alternating Tertiary sandstone, conglomeratic shell, and mudstone beds. The formation extends across much of the region, with thicknesses reaching up to 1,000 metres in places. It is exposed throughout large areas of the eastern hill country in central and south Taranaki.

In North Taranaki, the upper Matemateāonga aquifers are largely unconfined, while elsewhere in the region they are either confined or partially confined. Flowing artesian conditions occur at several locations, particularly within a band of incised hill country bordering the ring plain from Toko south to Ōhangai. The Tertiary sediments that make up the inland hill country also underlie the volcanic deposits of the ring plain. Extensive aquifers are found within the sand and shell bed layers.

There are currently 16 consents to take groundwater from Matemateāonga Formation aquifers. Water is taken for a range of uses, including dairy farming, industrial, and municipal supply. At present, abstraction pressure on the aquifers is limited. Monitoring by Taranaki Regional Council indicates that groundwater levels within the Matemateāonga Formation remain stable.

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.

Total allocated volume includes consented use only and no allowance has been made for 'permitted' use volumes.

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
