What is a UDAI? -- Jan 24 2012, 11:36 AM

A UDAI is the Unique Domain Authentication Identification and applies only to .nz domain names. It is a unique identifier issued at the time of registration of a domain name by the New Zealand SRS registry. It provides proof of authority to perform certain actions such as the transfer of a domain name from one registrar to another.

The UDAI can be obtained from your domain management control panel.
