There are two types of country classifications: the four-numeric classification and the two-alpha classification.
Statistics NZ maintains the four-numeric classification according to the numeric codes and names assigned by the UN Statistical Division and the International Organization for Standardization.
The four-numeric classification of a country is a hierarchical classification with three levels. There are nine major groups in level 1, 27 minor groups in level 2, and 244 countries in level 3.

The two-alpha classification of country is a flat classification containing 246 countries.
