What it does
The Customs (New Zealand Rules of Origin) Regulations 2006 (the Regulations) prescribe the technical methods for determining whether goods qualify as “originating” from New Zealand for the purposes of claiming preferential tariff treatment under the Customs Act 1901. They operate by giving operational meaning to concepts such as “regional value content” and “change in tariff classification” that the Act leaves to be defined. Specifically, the Regulations supply three separate formulas (build‑down, build‑up, factory cost) for calculating regional value content, and set out detailed rules for valuing materials that are used or consumed in production. The Regulations also provide a “tracing” mechanism: where a non‑originating material would not itself satisfy a required tariff‑classification change, it is nonetheless deemed to satisfy that change if it was produced wholly in New Zealand, or in New Zealand and Australia, from other non‑originating materials that individually meet the change (regulation 2.1). This prevents a single non‑qualifying input from disqualifying the finished good through a cascading failure of the tariff‑shift test.
The valuation rules in Part 4 are the mechanical core of the regime. They distinguish between materials imported into New Zealand by the producer, materials acquired in New Zealand, and materials produced by the producer itself. For each category a distinct valuation approach is mandated. Imported materials are valued in accordance with the WTO Customs Valuation Agreement; acquired materials use their purchase price plus transport to the factory; self‑produced materials require the sum of all production costs (including general expenses) plus a normal‑trade profit element. Critically, the Regulations then impose asymmetrical adjustments: for originating materials the producer may add freight, insurance, packing, duties that have been paid and are not refundable, and waste/spoilage costs; for non‑originating materials those same items must be deducted if they were originally included. This asymmetry directly increases the recorded value of originating inputs and decreases the recorded value of non‑originating inputs, making it easier to hit a required regional value content threshold.
