The Government’s own officials agree that New Zealand’s aluminium extruders have been seriously injured. Commerce and Consumer Affairs Minister Cameron Brewer has decided to do nothing about it anyway. On 5 October he declined the Aluminium Extruders Association’s (ALENZ) request for safeguard measures against cheap imports, mostly from China, saying he was “not satisfied of several matters” the Trade (Safeguard Measures) Act 2014 requires.
The industry’s response has been blunt. It has called the decision a “death warrant”. This is the hard edge of free trade policy, and it deserves a more honest debate than either side is currently offering.
The injury is real, the blame is shared
The stakes are not trivial. ALENZ’s application put the industry’s value at $600 million, supplying a $2 billion customer base across construction, marine, transport and manufacturing, with almost 2,000 direct jobs and more than 6,000 indirect ones, overwhelmingly in Waikato and Taranaki. ALENZ’s Nick Collins now warns roughly 1,000 jobs and local plants could go.
MBIE’s final report accepted serious injury but found imports were not the sole or primary cause. It pointed to a contracting domestic market and rising costs, and concluded a safeguard would likely raise prices for consumers and cut against New Zealand’s broader trade goals. Officials had signalled the same reasoning in September, when the Government refused interim duties while the investigation, formally initiated in May, ran its course.
That argument is not baseless. Extrusion lives and dies on the building cycle, and the building cycle has been brutal. Members’ energy costs also rose by between 38% and 152% over the application period. No tariff fixes either of those problems.
Finished product cheaper than the raw metal
But the import numbers are hard to wave away. Domestic output fell by approximately 40% between FY2023 and FY2025, while the share of the market held by Chinese imports priced below best manufactured cost climbed from 4.1% in 2021 to 21% in 2024. The same application documented extrusion landing at warehouse prices as low as $6.44 per kg. Low-cost imports rose a further 38% in the year to September.
McKechnie Aluminium Solutions managing director Dave Slomp says Chinese market share has gone from around 5% in 2015 to roughly 25% in 2025, and could hit 33% this year. “What we’re seeing here, Heather, is finished aluminium extrusion coming into New Zealand for less than the globally traded price of the raw materials that we’ve got to buy to make it,” he told Newstalk ZB.
That is not ordinary competition. A product selling below the cost of its own inputs is either being subsidised or dumped, and the free market case for letting it in is weaker than it looks.
New Zealand is the outlier
Slomp points out that Australia, the US, Europe, the UK and Canada have all taken safeguard or anti-dumping action against the same category of Chinese extrusions. He frames the industry’s ask in language a free-trader should recognise: “We shouldn’t throw one world-class industry under the bus in order to save another one. That’s just protectionism by another name.”
His suggestion that Wellington is protecting the dairy relationship with Beijing is speculation, not a stated rationale. But it lands because the alternative explanation is uncomfortable too. When every comparable economy treats this product as a problem and our regulator concedes the injury, “not the primary cause” starts to sound like a technicality. Slomp’s verdict is that the minister has “thrown a whole industry sector under the bus”.
Collins has made the more persuasive point: this is “not a failing industry asking to be propped up”, but one asking the Government to use legal safeguards that already exist. Safeguards are temporary, WTO-sanctioned and designed for surges like this one. Refusing to use them is a policy choice, not neutrality.
What buyers should be pricing in
For builders, boatbuilders and manufacturers, the immediate effect is cheaper inputs, and that is a genuine benefit. The risk sits further out. Collins argues local plants offer short lead times, small order runs and fast customisation. Once a plant closes, that capability does not come back when the building cycle turns. Buyers who enjoy cheap imports today may find themselves locked into long lead times and a single dominant supplier tomorrow.
The decision is defensible on the narrow legal test. It is less defensible as industrial strategy. If the Government believes energy costs and a weak construction market are the real killers, it owns both of those problems, and it should be judged on whether it fixes them before the next plant in Taranaki or Waikato goes dark. The industry’s remaining route is a targeted anti-dumping case, which is slower and narrower. Expect it to try, and expect the jobs clock to keep running while it does.
