What is a UDAI key?

UDAI is an acronym for Unique Domain Authentication.  All .nz domain names have a UDAI key which is specific to each domain and is used to change the registrar for your domain name.  UDAI’s are 8 characters long and consist of numbers and letters in both upper and lower case.  UDAI’s are case sensitive.  A UDAI key can be obtained by your current domain name registrar.  It provides an extra level of security for the domain name registration process
