What are we doing?
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.
Helicopter and drone inspections can be work to inspect the state and condition of the conductor (ie wire) closeup, or less frequently, aerial laser surveys (ALS) from around 300m height, which help identify the contours of the land underneath our conductors to help determine issues like vegetation growth impacting them.
