Halswell 11kV cable upgrades
Strengthening our power network
We’re upgrading our electricity infrastructure in Halswell to ensure a reliable and resilient power network.
Between late October and early December 2026, we'll be working in the Halswell area to install a new 11kV underground power cable. This work will be along Sparks Road, Halswell Road, Halswell Junction Road Kennedys Bush Road, School Road, Larsens Road and Glovers Road.
We installed part of this cable last year as part of a separate cable project on Sparks Road. To help minimise disruption to the community, we completed as much of this work as possible while traffic management was already in place.
Where we're working
This work will be carried out in stages to minimise disruption to the community. We'll let communities and businesses know when we're working in their areas.
