PowerNet and St John

In 2014, PowerNet and St John formed a 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.

Click here for information on the National Rural Fire Authority website and the links to the local Rural Fire Authorities.


For information about distances, responsibilities and trimming.
