What MainPower does

MainPower is a consumer-trust owned electricity distribution business (EDB) operating the regulated network that delivers power to over 46,000 homes and businesses across North Canterbury in New Zealand, spanning the Waimakariri, Hurunui, and Kaikōura districts. Founded in the 1920s and headquartered in Rangiora with operational depots in Culverden and Kaikōura, the company is 100% owned by the MainPower Trust on behalf of network beneficiaries. MainPower is regulated under Part 4A of the Commerce Act and supervised by the Electricity Authority, with pricing subject to Commerce Commission oversight. The company generates revenue through regulated usage-based lines charges, one-off connection application and design fees, and capital contributions for customer-initiated network works, with an annual customer rebate increased to $14M for 2026.

The core technology is a physical distribution network — overhead power lines, underground cables, zone substations, and grid connection points — supported by an Outage Management System with a public outage map, an online Customer Portal for service applications, and a Network Competency System governing contractor access. MainPower has expanded into distributed generation with the Cleardale mini-hydro station (approximately 4 million kWh annually), the newly commissioned Thongcaster Road Solar Farm (powering around 1,200 homes), and a resource-consented 93 MW Mt Cass Wind Farm projected as the largest in the South Island. Active capital programmes include the Cheviot to Kaikōura sub-transmission upgrade from 33 kV to 66 kV, a new Kaikōura Zone Substation, the Smarts Road upgrade for the Woodend/Ravenswood/Pegasus growth area, and proposed backup generation for Hanmer Springs.

Operationally MainPower runs a direct-to-consumer service model, supported by a 24-hour faults line, field crews across three depots, a $40,000 community fund, and partnerships with retailers, electricity contractors, and community organisations including a long-standing relationship with North Canterbury Sport and Recreation Trust. Leadership transitioned in January 2026 with the appointment of CEO Sean Horgan (ex-Waipa Networks, The Lines Company), while the board added Hilary Walton in August 2025 for technology and digital transformation expertise. The company is currently focused on network resilience, renewable energy build-out, and capacity expansion to serve regional population growth.
