All companies listed with the New Zealand Companies Office have just been assigned a New Zealand Business Number (NZBN).  This is the first step towards allocating all businesses in New Zealand a NZBN, and achieving a single searchable public register of businesses.  The purpose of NZBNs is to reduce the time and effort required on government forms and correspondence.  NZBNs have been automatically allocated to businesses and therefore there is no need for companies to take any action.  For more information click here.
