Click on the subject below to open the dropdown for more information.

Successful domain registration via RCP or API requires:

  • two or more nameservers or a nameserver group

If you are registering a .nz (top level) domain and the same domain name already exists in one of the second level domains (like .co.nz), it is mandatory to use the UDAI (authcode) of that domain to register the .NZ domain name. If you have any issues getting your UDAI, you can email at info@dnc.org.nz.

New WHOIS Privacy Setting for .NZ domains from March 8, 2023.

Whether contact information is displayed in the WHOIS now depends on the domain's new PRIVACY attribute. The value is default set to PRIVATE for individuals (personal data will not be displayed) and PUBLIC for organisations.

Individual Registrant Privacy Option is no longer available.


Successful domain transfer via RCP or API requires:

Registration agreement The registry requires that a registration agreement is in place between the provider and the domain holder. The text of this registration agreement and any required supplements is the following:
