PowerNet Limited is the electricity network management company delivering power to Invercargill City, Southland, West Otago and Frankton near Queenstown.

PowerNet was established in 1994 by network owners Electricity Invercargill Limited and The Power Company Limited to develop, manage and maintain their electricity network assets – lines, poles, cables, substations and other equipment, in a cost-effective way.

PowerNet manages the electricity networks of The Power Company Limited, Electricity Invercargill Limited, OtagoNet Joint Venture and Electricity Southland Limited (the Lakeland Network in Frankton).

Based on the regulatory value of the networks it manages, PowerNet is the equivalent of the fifth largest network company in New Zealand, delivering electricity to around 68,700 consumers.


The Grand Electrification of the South is now available to purchase for just $20.00 (including GST). Click here for more details. The Power Company Limited is donating the proceeds from the sale of the book to the local St John.


PowerNet and St John

PowerNet and St John have formed a three year partnership to improve public safety and first aid education.
PowerNet’s core focus is safety – safety of the public and safety of the people who work on our networks. We see St John at incidents – such as a car versus a power pole – they attend as first responders, and this takes our collaboration to a higher level.

PowerNet and the National Rural Fire Authority

Preventing Fires

PowerNet, the National Rural Fire Authority and the Rural Fire Authorities of Otago and Southland are working together to reduce the risk of rural fires across the Southland and Otago regions this summer.

Fires in rural areas can devastate the land and the local communities. This summer our regions are experiencing El Nino weather patterns which have increased the risk of fires in the dry rural areas.

With the combination of wind, dry weather and dry vegetation it is vital that extra care is taken. Prevention is the key so if trees or branches on your property are close to power lines contact PowerNet to have them checked or trimmed.
