ISO 3166-2:NZ

ISO 3166-2:NZ is the entry for New Zealand in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1.

Currently for New Zealand, ISO 3166-2 codes are defined for two levels of subdivisions:

• 2 islands (i.e., the North Island and the South Island)
• 12 regional councils, 4 unitary authorities, and 1 special island authority

Remote islands that are outside the authority of any regions, such as the Kermadec Islands and the New Zealand sub-antarctic islands, are not listed.

Each code consists of two parts, separated by a hyphen. The first part is NZ, the ISO 3166-1 alpha-2 code of New Zealand. The second part is either of the following:

• one letter: islands
• three letters: regional councils, unitary authorities, and special island authority
