Get an authorisation code (UDAI)?
A authorisation (UDAI) code is the key to your domain name. You need to protect your authorisation code, and make sure that your provider does not share your authorisation code with anyone else. Learn how to generate or request a UDAI code for your domain name.
Please note: There is no longer an ability to test an authorisation code that you have received. There are also some terminology changes below based on the new set of .nz Rules and the launch of the new .nz Registry System.
What is a authorisation code?
An authorisation code (UDAI) is a unique eight-digit code needed to transfer a .nz domain name from one domain name provider (registrar) to another. Some registrars also use authorisation codes to validate a change of domain name holder.
Authorisation codes are sometimes only able to be used once. It’s best to check with your domain name provider if you need to use your authorisation code for more than one transaction.
Step 1: Check to see if you can generate a authorisation code directly
Check your registrar to see if you can generate a UDAI for your domain name directly.
Some registrars or domain name providers offer automated UDAI generation. This function is usually accessed by logging into your registrar account and going to your dashboard.
Step 2: Check your WHOIS registration details
Check your WHOIS registration details using our WHOIS Lookup. Enter the domain name and click Lookup to see your domain name details. Make sure they are up to date.

Step 3: Request an authorisation code from your domain name provider.
To get a UDAI code, you may need to email or call your domain name provider (Registrar). They may also ask for evidence to prove that you are the domain name holder.
Registrars will only provide an authorisation once they are confident it is the registrant requesting it.
