About PowerNet
PowerNet Limited is the electricity network management company delivering power to Invercargill City, Southland, West Otago, parts of Central Otago and Stewart Island.
PowerNet runs the lines and underground cables that carry electricity from the national grid into homes, farms and businesses across their service area. They are not an electricity retailer — they are the lines company that owns the network itself.
PowerNet is one of 7 utility operators active in Southland. Most building or landscaping work in this area touches multiple operators' networks at once — power, water and communications cables routinely share the same trench. The list further down shows the other utilities you'll likely need to contact alongside PowerNet.
