New Zealand Rejects Aluminium Extrusion Import Safeguards Amid 29.8% Market Contraction
Meta Description: New Zealand’s government has rejected safeguard tariffs on aluminium extrusion imports. The domestic market has shrunk 29.8% since 2022, with ALENZ warning of thousands of manufacturing job risks amid rising import competition.
New Zealand’s government has rejected calls for import safeguard measures on aluminium extrusions, despite an official investigation confirming serious injury to domestic manufacturers. Commerce and Consumer Affairs Minister Cameron Brewer accepted the Ministry of Business, Innovation and Employment (MBIE) recommendation on 5 October, prompting the Aluminium Extruders Association of NZ (ALENZ) to warn of risks to local plants and thousands of jobs.
The ruling marks the first conclusion of an investigation under New Zealand’s Trade (Safeguard Measures) Act 2014. ALENZ lodged the application in January, seeking tariff relief to slow imports — predominantly from China — which it said were priced at levels that undercut local producers.
Domestic Aluminium Extrusion Market Contracts 29.8% Since 2022
MBIE data shows New Zealand’s domestic aluminium extrusion market totalled 16.4 million kg in 2025, down 29.8% from 23.4 million kg in 2022. Local production for the domestic market fell 32.4% over the same period, from 15 million kg to 10.1 million kg.
Import volumes also declined 25% over the three-year period, from 8.4 million kg in 2022 to 6.3 million kg in 2025. However, imports rebounded 34% year-on-year in the first seven months of 2026, though they remained only around 5% above 2024 levels following a 22% drop in 2025. MBIE noted it was too early to confirm a sustained upward trend, and linked the 2026 import rise to the Building Amendment Act 2025, which lowered barriers for overseas building products.
MBIE Ruled Against Safeguards Over Broader Economic Factors
MBIE concluded that while imports contributed to industry pressure, they were not the sole or primary cause of injury. The investigation identified multiple drivers of the downturn: weakening construction activity and broader economic conditions that reduced domestic demand, rising raw material costs, and falling export volumes.
Aluminium billet landed prices rose from roughly NZD 4–4.60 per kg in 2022–2024 to more than NZD 7 per kg by mid-2026, with some industry cost increases outpacing inflation. Export volumes also fell from 3.3 million kg in 2022 to 1.5 million kg in 2025, reducing factory throughput and operational efficiency.
The ministry warned that safeguard tariffs would push up prices for downstream manufacturers and consumers. It also noted risks of broader trade repercussions for New Zealand as an export-oriented economy, and said the measure would not address the core domestic drivers of the downturn.
Brewer confirmed the inquiry focused on safeguards, not anti-dumping measures. He said the industry could pursue a separate investigation into anti-dumping or countervailing duties, and MBIE would work constructively with the sector on its options.
Industry Warns of Permanent Job Losses
ALENZ chair Nick Collins criticised the decision as a serious setback, warning it put thousands of jobs at risk including more than 1,000 manufacturing roles across Hamilton, New Plymouth and Wellington. He said plants that close may never reopen, and called for the decision to be revisited after New Zealand’s 7 November election.
The association is reviewing its next steps, with a separate anti-dumping or countervailing duties investigation remaining a possible path. NZ First leader Winston Peters also criticised the ruling as a backward step, citing risks to domestic manufacturing capability and supply chain resilience.
The ruling leaves New Zealand’s aluminium extrusion sector without the temporary trade protection it sought. While MBIE found the evidence did not meet the threshold for safeguard intervention, the industry continues to face pressure from declining domestic production, elevated input costs and renewed import growth.
