Two exits, one diagnosis
Heinz Wattie’s is closing factories in Auckland, Christchurch, and Dunedin plus frozen packing lines in Hastings, cutting around 300 roles. McCain Foods is shutting its Hastings plant by January 2027. Between them, these decisions gut New Zealand’s domestic frozen vegetable processing capacity. David Hadfield, chairman of Processed Vegetables NZ, was blunt about the cause: local production costs were high and it was cheaper to import.
The frozen vegetable aisle matters less than what killed it. The same economics are grinding down manufacturers across the country, and nobody has a credible plan to fix them.
Costs stayed high while prices collapsed
The margin trap is visible in the data. The Infometrics-Foodstuffs Grocery Supplier Cost Index hit 10.6% annual increases in December 2022, with nearly 2,300 grocery items still rising in cost as late as March 2024 and 7.1% of monthly price changes representing jumps of 20-40%. Input costs did not come back down when inflation moderated. They stuck.
Retail prices did not stick. Ready-to-eat food inflation crashed from a peak of 9.8% in mid-2023 to just 2.1% by mid-2025. Processors were squeezed from both sides: suppliers charging more, retailers refusing to pass it on. For a commodity product like frozen peas with no brand premium to protect, the maths simply stopped working.
Electricity costs made it worse. Hawke’s Bay farmer Hamish Marr, who supplied peas to Wattie’s for 20 years, captured the absurdity: ‘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.’ Associate Energy Minister Shane Jones went further, pointing at the gentailers’ non-competitive structure as a direct drag on manufacturing viability.
Uber Eats is eating the volume
Cost is only half the equation. Demand for frozen vegetables has been falling structurally, and Woolworths has confirmed declining frozen vegetable sales. Just 6.8% of New Zealand adults now eat recommended vegetable portions, according to Ministry of Health figures.
Hadfield identified the delivery economy as a structural driver. ‘With Uber Eats etc, there’s not a lot of vegetables in the package that you get to eat,’ he said. Fewer people cooking at home means fewer bags of frozen vegetables moving through checkout. In a market of five million people where 80-90% of vegetables grown domestically are consumed locally, even a modest demand shift destroys the volume economics that justify industrial-scale processing.
The damage runs deeper than factory gates
The closures cascade outward. Around 220 vegetable growers in Canterbury and 100 in Hawke’s Bay face direct impact. Central Hawke’s Bay mayor Will Foley has quantified 9,000 hectares of vegetable-growing land affected in his district alone from the McCain closure.
Then there is the seed industry. Canterbury produces more than half the world’s hybrid radish seed and 40% of global carrot seed supply, exporting to over 60 countries. Pea processing underpinned pea seed contracts feeding into that system. Sarah Clark, chief executive of Seed and Grain New Zealand, explained the chain reaction: less demand for pea seed means fewer contracts for growers, and processed vegetables are a rotation crop that fixes nitrogen and supports whole-farm systems. Losing them forces difficult transitions across entire farming operations.
The question nobody in manufacturing wants to ask
Buy NZ Made executive director Dane Ambler called it a perfect storm for local manufacturers already operating on tight margins. But perfect storms imply bad luck. This is not bad luck. It is a structural cost base that makes commodity manufacturing uncompetitive in a small, isolated market with expensive electricity, heavy compliance costs, and weakening domestic demand.
Vegetables NZ warned directly: ‘We cannot rely on imported food to feed us.’ In a world of rising trade friction and shipping volatility, that is not alarmism. But the food security argument will not save a single factory if the economics remain broken.
Marr’s summary lands hardest: ‘It’s another nail in the coffin for poor old NZ Inc.’ The frozen vegetable sector did not die of anything exotic. It died of high costs, weak demand, and a market too small to absorb both. Every manufacturer in New Zealand running a commodity product line should be checking whether the same forces are quietly closing in on them.
