WATER INFORMATION PROJECT:
AERIAL GROUNDWATER MAPPING
Aerial mapping of Tairāwhiti aquifers postponed until summer 2023/2024
[Press release: 2 March 2023]
A scientific project to map Tairāwhiti aquifers from the air has been postponed until next summer. Aqua Intel Aotearoa Programme Director Jane Frances says “Cyclone Gabrielle has been devastating for the people of the region, and our thoughts are with all those affected. We don’t want to get in the way of critical response and recovery work so we are postponing the aerial survey.”
Aerial Groundwater Mapping
The Aerial Groundwater Mapping project was planned to be undertaken using a helicopter during February, 2023. The widespread effects of cyclone Gabrielle resulted in the project being delayed, likely until summer 2023/2024. Mapping will be undertaken in Wharekahika (Hicks Bay), Te Araroa, Waiapu, Tologa Bay, and Poverty Bay Flats.

About the Aerial Groundwater Mapping Project
The Aerial Groundwater Mapping project is a scientific investigation to find out more information on the aquifer systems in Tairāwhiti/Gisborne. Aerial mapping of aquifers by helicopter will be carried out in Wharekahika (Hicks Bay), Te Araroa, Waiapu, Tolaga, and across Poverty Bay flats (in the areas shaded orange on the map below).
We already know some information about the aquifers (e.g., from groundwater drilling) but we want to fill in information gaps. Knowing more about the aquifers will help us to identify the best ways to balance environmental protection, the increased demand for water, and events such as droughts.
Who is supporting the mahi
The project has formed from collaboration between AIA and Gisborne District Council, in discussion with iwi. The $1.8 million project is largely funded through Aqua Intel Aotearoa, a national programme on regional water availability and storage. AIA is a collaboration between Kānoa (the delivery arm of the Provincial Growth Fund) and GNS Science.
What we want to learn
We will never know everything about the aquifer, but this study will give us a better understanding of:
what the aquifer looks like (e.g. depth, extent, geology)
how the aquifer is connected to wetlands, lakes and streams
the relationship between shallow (unconfined) and deeper (confined) aquifer systems
the boundary between the aquifer and seawater (seawater intrusion risk)
how groundwater recharges.
