An aeromagnetic survey of the Northland region was completed in 2011. The survey was conducted as a partnership between the Ministry of Economic Development, the Far North District Council, Enterprise Northland and the Northland Regional Council. Over 13,590 square kilometres were surveyed and 80,710 line kilometres of data collected.
The survey provides valuable information on the subsurface geology of Northland. GNS Science, a government research agency, has interpreted the data to identify geological and structural elements in the survey area.
For the Northland region, this data will also have a wide range of applications in fields such as geological mapping, geothermal exploration, forestry, agriculture, horticulture, geological hazard assessment, and engineering and construction investigations.
Reports from the survey are available from New Zealand Petroleum & Minerals - Online Exploration Database
