We need to continually operate, maintain and develop New Zealand's transmission network – the National Grid – to ensure we meet the ongoing electricity needs of New Zealanders. To ensure our lines continue to provide a safe and secure service, we periodically undertake helicopter or drone inspections of our lines.
By inspecting our lines regularly by air we can identify and resolve issues before they impact on supply and or public safety.
Low flying helicopters or drones may be distracting, particularly for sensitive land uses or times (eg stud farms or during lambing/calving). Please check our notices below for our next flyovers:
