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:

Some of the New Zealand outlying islands that are outside the authority of any regions are not assigned codes, specifically:

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

Subdivision names are listed as in the ISO 3166-2 standard published by the ISO 3166 Maintenance Agency (ISO 3166/MA).
