The infrastructure you build is only as good as the care it gets afterwards. Our teams deliver the cable diagnostics, planned maintenance, asset inspections, and rapid fault response that keep critical networks performing safely – backed by local crews, specialist gear, and the supply chain depth to mobilise when it matters most.
When a cable fault hits, every hour counts. Our fault response crews bring over 20 years of cable fault location experience and thousands of faults resolved across Aotearoa – using $300k+ purpose-built diagnostic trucks equipped with VLF and TDR testing to pinpoint the exact location of the problem, often in minutes rather than days. That precision means less excavation, less disruption, and faster restoration. We mobilise quickly, with the local crews and critical spares to get your network back online fast.
Our teams deliver systematic asset inspection and condition assessment programmes across substations, overhead and underground networks – covering poles, structures, cables, and associate equipment. Using GPS-enabled digital systems, we assess condition, prioritise interventions, and build a clear network-wide view of your asset health. The data feeds directly into lifecycle planning and renewal programmes – so your capital goes where it delivers the most value. For private networks, we set up and run the inspection and maintenance routines that meet your regulatory obligations – something not every asset owner realises they carry.
We service circuit breakers, transformers, and protection systems across substations and high-criticality assets – including certified Hitachi tap-changer maintenance. Our technicians deliver planned maintenance programmes that extend asset life and catch issues early, backed by advanced diagnostics and mobile workshop capability that means we can work on your site without moving your gear off it.
When severe weather hits, our crews are already moving. We mobilise for fault restoration, make-safe activities, and temporary structures – drawing on our own stockholding of critical spares and the relationships with peer networks that let us share resources when multiple regions are affected at once. The October 2025 South Island storm proved what that looks like in practice: transformers heading south before the roads reopened, and line guards air-freighted across Cook Strait on a Sunday.
