The closures are symptoms, not the disease
Heinz Wattie’s is shutting factories in Auckland, Christchurch and Dunedin, axing frozen vegetables, Gregg’s coffee and hummus production. Some 350 workers face redundancy and 220 suppliers lose a major buyer. In the seafood sector, Sealord Group CEO Doug Paulin has described “relentless” cost increases eroding profitability at one of the country’s biggest exporters.
The mainstream framing treats these as separate corporate stories. They are not. They are two data points on the same curve, and the curve is being drawn by energy prices that have been quietly taxing New Zealand manufacturing out of existence.
The $5.2 billion nobody talks about
An MBIE-commissioned report from Sense Partners, published in July 2025, modelled the cumulative impact of elevated electricity and gas prices between 2017 and 2025. The findings should have triggered a political crisis. They barely made the news.
Real GDP was 1.25% lower by 2025, equivalent to $5.2 billion, than it would have been without the price increases. Primary metals production fell 15% below baseline. Paper products dropped 7%, chemicals 5%, and even dairy processing, the supposed backbone of the export economy, was 1.3% lower. Real wages fell 1.4% and real exports dropped 0.8%, worsening the trade balance by $275 million.
This is not a modelling exercise buried in a think-tank white paper. It is the government’s own commissioned research, telling the government that its electricity market structure has destroyed billions in economic value. The response has been silence.
Freight costs are the second squeeze
Energy does not just hit the factory floor. It flows through the entire supply chain via freight. NZ Trucking Association CEO David Boyce has warned that fuel now accounts for 30% of trucking operating costs, up from 8-10% before recent geopolitical disruptions. Fuel has overtaken labour as the sector’s biggest cost line.
Boyce is blunt about the transmission mechanism: “Transport operators run pretty lean and mean on their pricing. There’s not much wriggle room for them to absorb costs, so they really have to pass it on to their customers straight away.”
For food manufacturers, the maths is punishing in both directions. Energy inflates factory costs. Freight inflates inbound raw materials and outbound distribution. There is no margin left to absorb either.
A farmer who watched 20 years of supply evaporate
Methven farmer Hamish Marr, who supplied peas to Wattie’s for two decades, captured the absurdity perfectly: “We live in a country with some of the most sustainable electricity in the world, and yet we’re paying record high prices for electricity.”
Process Vegetables chair David Hadfield raised the stakes further, warning that losing local food production makes the country more vulnerable to disrupted shipping routes. The Employers and Manufacturers Association echoed the concern, warning of ripple effects across the economy. This is no longer just an efficiency question. It is a food security question.
Shane Jones said the quiet part out loud
Associate Energy Minister Shane Jones has been the most direct voice in government, calling out the gentailer oligopoly: “Look no further than the non-competitive structure, the non-competitive level of cost imposed on our manufacturing sector by the electricity sector. That’s why the electricity sector either has to be regulated or cut in half.”
That is a remarkable statement from a minister in a pro-market government. It is also, so far, just a statement. Regulation or structural break-up of the gentailers would be a major intervention. There is no bill, no timetable, no policy paper. In the meantime, Treasury’s Half Year Economic and Fiscal Update frames the broader fiscal constraints that make bold action politically difficult.
The question every manufacturer is asking
The pattern is now undeniable. Energy costs have extracted $5.2 billion in GDP over eight years. Freight costs have tripled as a share of trucking operations. Wattie’s is exiting. Sealord is warning. The government’s own research quantifies the damage and the government’s own minister names the cause.
Every food manufacturer, every processor, every factory operator in New Zealand is now running the same spreadsheet. The numbers say the same thing: making things here costs more than importing them. Until the input cost structure changes, the closures will keep coming. The only question is whether Wellington acts before there is nothing left to save.
