The Ministry for Business, Innovation and Employment (MBIE) is currently conducting an aeromagnetic survey across the South Island, which will involve a number of low-flying helicopters travelling up and down the district.
The survey will help MBIE understand the geology of the area, including mineral deposits, earthquake fault lines, soil types and water resources.
Flights will operate until April 2018 and the aircraft are expected to only spend a short time over any given location but may do several passes.
The survey helicopters will be easy to spot as they have a protruding boom (like a jousting lance) which houses the survey instruments.
Please note that the helicopters will fly low (at around 35 metres) and the noise could disturb nearby people and animals
The flights are only permitted to operate during daylight hours and are subject to the rules and regulations of the Civil Aviation Authority.
