I'm getting error "Changes to the registrant's First Name, Last Name, or Organization are not allowed for the selected domain extension.", when I try to transfer my .co.nz domain to another person.
Can anyone please guide me how to resolve it.
I am sorry to hear that you are having trouble with your domain transfer but it would appear that we do not support 3rd parts transfers for .co.nz domains according to this article:
however you should be able to change the owner from godaddy to godaddy account.
I suggest calling into support to check what restrictions might be preventing the changes.
