Area code information

National numbering format

Geographic (fixed/conventional) numbers have 1-digit area code with 7-digit subscriber number.

Access to Scott Base in Antarctica is a special case, where the area code 2409 is followed by the 4-digit number on the base. In international format, this is +64 2409xxxx.

McMurdo base, although an American operation, is also reported to be dialable as +64 2409xxxx as the facility is located within the Ross Dependency sector of Antarctica.

Wireless numbers normally have 2-digit area codes, followed by 6- or 7-digit subscriber numbers.

Many special services have 2-digit area codes with 6-digit subscriber numbers.

Further details are indicated in a Ministry of Economic Development announcement (September 2003, via ITU).

September 2005 - +64 21 mobile number lengths updated

Mobile numbers under +64 21 were followed by 6 or 7 digits since 2003. In September 2005, an extra digit was possible for numbers in range +64 210 e.g. numbers in formats +64 210 xxxxx, +64 210 xxxxxx or +64 210 xxxxxxx (that is, the national number length could be 8 to 10 digits, excluding any country code or trunk prefix).

Other +64 21 ranges continued to be limited to national number lengths of 8 or 9 digits (that is, +64 21 xxxxxx or +64 21 xxxxxxx).

1991-1993 - national renumbering

A New Zealand renumbering took place in the 1991-1993 period to consolidate the numbering plan so that conventional fixed numbers have a consistent format of a single-digit area code plus a 7-digit subscriber number. The New Zealand Phone Number Update program reduced the number of geographic area codes from 80 to 5.
