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 Fire and Emergency New Zealand

Preventing Fires

PowerNet and Fire and Emergency New Zealand are working together to reduce the risk of rural fires across the Southland and Otago regions each 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.
