Find a postcode

You can find New Zealand postcodes along with postal addresses, rural delivery, & PO Boxes using the Address & Postcode Finder.

How postcodes work

Postcodes are four digits, and each digit has a specific meaning.

The first digit of the postcode represents one of ten machine 'lines' (numbered 0 - 9), which process mail for a specific geographic region. These run north to south in ascending order.

The second and third digits reflect postal sort areas and our delivery network - urban posties, Private Boxes and Rural.

The fourth digit identifies the urban area, specific box lobby or rural delivery round.

How to use postcodes

A postcode should be used on all addresses. If the postcode contains a leading zero, this zero must be included. The postcode must not include separators or spaces.

There are only one or two spaces between town/city and postcode, for example:

  • Auckland 1112
  • Christchurch 8110
