The Hawke’s Bay 3D Aquifer Mapping Project (3DAMP) is New Zealand’s most extensive groundwater mapping initiative, undertaken by GNS Science in collaboration with the Hawke’s Bay Regional Council and Aarhus University HydroGeophysics Group. Leveraging SkyTEM technology, this five-year project (2019-2024) utilized a helicopter-mounted survey system to scan groundwater reserves within Hawke's Bay's Heretaunga and Ruataniwha Plains and the Poukawa and Otane basins. The project’s objective is to create a 3D subsurface map to improve groundwater management, particularly under climate change and increasing water demand. The project’s scope includes processing over 8,000 km of electromagnetic (EM) survey data to identify aquifers and develop hydrogeological models, thereby enabling sustainable water resource planning and facilitating a transition to lower-nutrient, high-value agricultural practices.
