Pole top photography and LiDAR

Per Civil Aviation Authority (CAA) requirements, the helicopter will only be flying in open air space. That means it will fly above 1,000 feet in urban areas, and above 500 feet in rural areas.

Your privacy will not be impacted by our survey work. We are only taking photos of our poles and crossarms, not residential properties. The photos are for internal asset assessment purposes only and are held in a secure location. Here is an example of the type of photos taken:

There are a few reasons we don't use drones:

• Helicopters offer a fast way to cover the distance required, some of our power lines are over 200km long and completing the capture faster means less impact on our customers.

• Civil Aviation New Zealand Rules say that we must maintain a visual line of sight with the aircraft and be able to see the surrounding airspace in which the aircraft is operating.

• Powerco's network extends across every airspace type in New Zealand, this includes Control Zones, Military Areas and Low-flying Zones, all of which require a piloted aircraft to complete safely.

As legislation and technology process, Powerco will consider the use of fixed-wing or VTOL drones to complete future Pole Top Photography programmes.

Aethon Aerial Solutions, who will contract local pilots to carry out the work.

Our electricity network stretches across the North Island, made up of about 264,000 poles. It is impossible for us to survey all of these in one summer, so we’ve been spreading out the surveys since 2018.

Once we have captured images of every rural pole through our surveying, we will likely move to routine inspections every one to two years.
