Five words no exporter wanted to hear
Asked on the Newstalk ZB breakfast show on 20 July 2026 when the next US tariff would hit, Prime Minister Christopher Luxon was blunt: “We don’t have any idea.” He added there would “continue to be strong demand for New Zealand goods” – reassurance that does nothing for a firm trying to lock a US supply contract before the weekend.
The timing matters because the number is close. Trade experts told RNZ on 17 July 2026 that New Zealand could face a blanket 12.5% tariff on all exports to the United States as early as Friday 25 July, up from the current 10%. That is not a distant policy risk. It is a cost layer that could land within days of the Prime Minister saying he can’t say when.
Why Friday, and why 12.5%
The date is not guesswork. The current 10% rate sits under Section 122 of the Trade Act of 1974, which carries a statutory 150-day cap unless Congress extends it. That clock, running from late February, expires in late July. The US Trade Representative has meanwhile been running Section 301 investigations covering New Zealand and 85 other countries, the legally durable replacement mechanism the administration intends to use once Section 122 lapses.
The 12.5% figure is the tell. As Deborah Elms, head of trade policy at the Hinrich Foundation in Singapore, told RNZ, New Zealand “falls in the 12.5 percent bucket not because it is a worse offender on forced labour issues, but because it does not have a bilateral trade deal with the United States, so it by default goes into the 12.5 percent category.” Elms also noted Washington’s habit of releasing unwelcome news late on a Friday, which points to Friday 25 July NZ time.
The cost is already measurable
This is not theoretical. Stats NZ’s March 2026 merchandise trade data shows goods exports to the US fell $56 million, or 5.9%, year-on-year, while imports from the US dropped $95 million, or 13%. Annual goods exports hit $81.0 billion, up $7.1 billion overall, but the US line is moving the other way.
The playbook is familiar. When the original 10% tariff arrived in April 2025, MFAT’s assessment recorded exports to the US falling 4.3% in May 2025 and 8.9% in June 2025 before a partial recovery, as exporters front-loaded shipments then US importers pulled back orders. The US accounted for around 13% of New Zealand’s exports. A 2.5-point jump on that base is real money spread across meat, wine, dairy and manufactured goods.
The relative position nobody should relax about
There is a genuine nuance worth pricing in. Elms points out that China, the EU and Japan face additional tariffs stacked on top of the baseline, which could leave New Zealand’s 12.5% below what some competitors pay for comparable goods. That is a competitive edge in certain categories, not a reason to shrug. Which markets and which rival exporters matter to your product line will decide whether 12.5% is a hit or a handhold.
The structural problem the government keeps answering slowly
The reason New Zealand sits in the higher bracket is simple. It has no bilateral free trade agreement with the United States. Countries that do sit in more favourable brackets. New Zealand has FTAs with most major partners but not the one imposing the tariff, and the government’s response – negotiate more agreements – is the right answer to the wrong timeline.
Trade Minister Todd McClay has framed the rise as “not unexpected” and repeated that the government will keep pursuing “high-quality trade agreements with like-minded partners.” That is a multi-year project. It does nothing for the firm invoicing a US customer this week.
The uncomfortable truth is that the tariff rate is not the shock. Businesses can model a 12.5% cost. What they cannot model is uncertainty on timing coming from the top of government days before a plausible deadline. If the tariff lands on Friday night Washington time, exporters will have had exactly the warning the Prime Minister gave them, which is to say none. Price the risk in now, because the government’s certainty is arriving on a slower boat than the tariff.
