The UK's Agriculture and Horticulture Development Board (AHDB) offered an assessment of the New Zealand-UK trade deal's potential impact on pork exports. According to the assessment, any changes to trade flows for pork as a result of the trade deal will be minimal.

For pork, the chosen network consists of the UK, New Zealand, the EU, the USA and China. AHDB said pork is different to the other agricultural commodities it assessed, as New Zealand is a net importer rather than exporter. The UK is also a net importer, although it does export some pork products to New Zealand, the EU and China. In contrast, the EU and USA are significant global exporters.

The model predicts that there will only be slight changes to trade flows as a result of the trade deal coming into operation. The trade deal will remove existing tariffs on pork products from New Zealand, allowing them to access the UK market at zero tariff. However, the model does not expect exports to increase. This is because New Zealand only exports a tiny amount of pork, and these exports would not be price competitive on the UK market.

The UK already exports some pork to New Zealand. Again, the model does not expect the current position to change. This is because the trade deal does not improve UK access as New Zealand, as they already do not apply tariffs on pork imports. The deal also does not change the rigorous set of Sanitary and Phytosanitary (SPS) measures for access to the New Zealand market.
