There are extra import requirements for foods that have made people sick in the past, and foods that are more likely to make people sick. These "foods of regulatory interest" include a variety of products.
Foods of regulatory interest
Histamine-susceptible fish and fish products.
Ready-to-eat smoked fish and smoke-flavoured fish.
Bivalve molluscan shellfish.
Bovine meat and bovine-meat products.
Fermented meat products.
Meat paste and pâté.
Nuts, seeds and fruit
Peanuts, pistachio nuts, and their products (including peanut butter).
Tahini and crushed sesame seeds (and any products containing them).
Frozen berry fruits.
Food safety clearances
You'll need a food safety clearance to import any of these foods. That will require you to demonstrate the food's safety in one of 4 ways:
NZ Importer Assurance: A registered food importer that's verified by MPI can be issued with a NZ Importer Assurance (previously known as a Multiple Release Permit).
Manufacturer's declaration: Bovine meat and products containing bovine meat that are imported from Australia must be accompanied by a manufacturer's declaration that the meat is of Australian or New Zealand origin.
Official certificate: For some countries, MPI will accept official certificates (from the appropriate government agency) as assurance the food is safe. The certificate must be from the country of origin to for New Zealand. Certificates issued for other countries are not acceptable.
Sampling and testing: In some cases, food will have to be sampled and tested. MPI will tell you if this is required.
Foods from Australia
Most foods from Australia can be imported without food safety clearance, except:
bivalve molluscan shellfish and products containing them
bovine meat and meat products containing more than 5% bovine meat.
