Client codes

  • A client code is a unique number that identifies commercial importers and exporters for customs clearance purposes.
  • A client code is required for:
    • imports and exports valued at NZ$1000 or more
    • importing food for sale or food ingredients for use in food for sale, no matter the value
    • importing a motor vehicle, no matter the value
    • exports that need a permit, no matter the value.
  • Once you have a client code, you’ll need to use it for all eligible imports and exports.
  • You can apply for a client code yourself.
  • If you are using a customs agent, they can apply on your behalf. The customs agent will advise what documentation they require to be sent to them.

To apply for a client code yourself:

If you are a food importer, follow the instructions under 'Apply for a client code as a food importer" instead.

If you are importing food for sale or food ingredients for use in food for sale, no matter the value, you must register as a food importer.

  • You can apply for a client code as a food importer yourself.
  • If you are using a customs agent, they can apply on your behalf. The customs agent will advise what documentation they require to be sent to them.
