Electricity lines
This page was updated7 months ago
The electricity lines industry in New Zealand is regulated by the Commerce Commission.
Our role in electricity lines
Getting power to your home or business is a complex process. Electricity is first generated from a variety of sources, before being transmitted across the national grid, distributed down the power lines and sold to you. More than 50 businesses across New Zealand play their part in that process.
