  Almost every battery commissioned in New Zealand in 2024 and 2025 was either manufactured in China or contained substantial Chinese components. The same will be true through 2026 and very likely through the rest of the decade. This is not a criticism of the technology or the suppliers — Chinese battery manufacturing is genuinely world-leading on cost, scale, and increasingly on quality. It is a question worth asking deliberately, because at some point a strategic dependence built by default starts to constrain options that were not consciously traded away. The conversation New Zealand needs to have about its energy transition is not whether to use Chinese batteries. The pragmatic answer to that question is yes, with eyes open, because the alternative supply chains do not yet exist at the scale and price the transition requires. The conversation is about what level of dependence is acceptable, where the failure modes are, and what New Zealand should be building locally to retain o...

Most coverage of New Zealand's energy transition focuses on the big infrastructure — Glenbrook, Huntly, Ruakākā, the major utility battery projects. The quieter story, and possibly the more important one, is happening at the other end of the scale. Across dairy farms, packhouses, orchards, and poultry operations, the agricultural sector has begun a coordinated rollout of on-farm solar and battery storage that, if the EECA's own modelling is right, could eventually supply ten per cent of New Zealand's national electricity demand. In February 2026, EECA announced the first 32 farms selected for its Solar on Farms demonstration programme — 3,616 kilowatts of solar capacity spread across ten different farm types, with battery storage from 30 kilowatt-hours to 500 kilowatt-hours per site. Over 230 farms applied. The successful 32 will receive 40 per cent co-funding for batteries and inverters, plus 20 per cent for the remaining solar costs. Installations began in January 2026 an...

  Every conversation about New Zealand's renewable transition starts with megawatts. Solar farms approved, wind capacity consented, battery storage commissioned, transmission upgraded. The conversation that gets had less often, and matters at least as much, is about the people. Specifically: whether New Zealand has anywhere near enough qualified engineers, technicians, and grid specialists to actually install, commission, and maintain the infrastructure the country has committed to building. The evidence increasingly suggests we do not. Engineering New Zealand's published figures put the gap at roughly 2,300 new engineers a year — a shortfall described as long-term and getting worse. Only 9 per cent of New Zealand's degree graduates have studied engineering, well behind the OECD average. A third of engineering graduates leave the profession for unrelated roles within two years of qualifying, and around a third of the country's current engineering workforce trained overs...

  New Zealand commissioned its first utility-scale battery in 2024. Several more are coming through 2026 and 2027 — Glenbrook, Huntly, Ruakākā, the Eku Energy Waikato project. None of them is anywhere near end of life. Which is precisely why this is the moment to ask what happens when they reach it, because the answer will shape national infrastructure decisions a decade before the first system needs replacing. Energy storage is a long-cycle asset class. The decisions being made in 2026 will, in the case of lithium-ion installations, produce a wave of end-of-life material around 2036 to 2040. That sounds far off, until you remember that the recycling infrastructure to handle it would need to be built years in advance, and that countries further down the deployment curve than New Zealand are already discovering how poorly that timing tends to work. The Li-Cycle warning In January 2025, one of North America's most prominent lithium-ion battery recyclers, Li-Cycle, filed for bankruptc...
