Here's a helpful guide of recommended large shrubs and small trees suitable for growing under or near power lines.
The plants on this list have a mature height in Northland of between 2.5 and 4 metres.
Even though the trees listed are considered suitable for planting near powerlines, please remember it's the tree owner who is responsible for maintaining trees at a safe distance from the lines.
The plants in this list grow to suitable heights around powerlines, or are lightly branched and easily trimmed when they grow bigger.
This list is by no means exhaustive - many more trees and shrubs can be successfully maintained at a height that won't interfere with powerlines simply by regular, appropriate pruning.
