Cable Locations

Protect yourself from the hazard of underground cables

Unison has a large network of underground electricity and fibre-optic cables, especially in urban areas. These are commonly located alongside roads in the utility corridor, but can also be in parks, on commercial or industrial sites, or even through private property.

Under Health and Safety Legislation it’s your responsibility to locate all underground services, including electric cables, before undertaking earthworks or digging. Worksafe New Zealand publish the following guide outlining your responsibilities and safety practices working around underground services; 

Think you have a rough idea where they are?

It still pays to get the cables located.  Subsidence and earth works can cause cables to move, so when you look at the life-threatening risk of guessing and getting it wrong, it’s worth taking the time to get them located.

We use cable route tracing equipment and ground penetrating radar to locate and mark underground Unison network cables.  In all situations, having underground cables located before carrying out work, on or around your property, is a life-saving decision.

Cable Location and Mark-out service

Unison provides a free Plan Service and also offers a Cable Location and Mark-out service for location of our underground electricity network and fibre network cables.

Additional requests may incur a charge.
  • For all infrastructure owners, utility asset owners (including territorial authorities) and all utility corridor contractors working in the utility corridor, Unison offers location services for which charges apply.
