Power Politics: How high electricity prices are squeezing NZ Manufacturers in an Election Year
By Sean Doherty,Manufacturing Commentator | NZ Industry Trends New Zealand’s electricity market is producing two parallel realities. For the country’s four major generator-retailers, business has never been better. For manufacturers, the same market is steadily destroying the economics of making things in this country. If the balance is not corrected soon, the closures already under way will accelerate – and some of the damage will be permanent. Generators cash in while industry burns out In the six months to December 2025, New Zealand’s four major gentailers – are forecast to deliver a combined operating profit of approximately $1.86 billion, an increase of around 45% on the same period a year earlier. These are not one-off results. In 2023, the same four companies posted combined operating profits of $2.7 billion – roughly $7.4 million in profit every single day. The Electricity Authority’s own energy margin dashboard shows big generators regularly earning weekly gross margins in excess of $70 million, peaking at around $119 million in some high-price weeks. Consumer NZ chief executive Jon Duffy has put the problem plainly: “We hear the same lines every year. Big profits are needed to fund investment. But the investment is always coming, never here in sufficient quantity“. The numbers back him up. Analysis by the NZCTU and 350 Aotearoa found that over the past decade, the four gentailers paid $10.8 billion in dividends to the government and shareholders while investing only $4.5 billion into plant, property and equipment. Transpower data showed that as of late 2025, only around 986 MW of new generation had been committed and financed – far short of the 1,500 GWh of new capacity needed every year until 2031. The system, in other words, is structured to reward generators most when supply is tight and prices are high – […]
