Wanting to register a domain? You can register your domain name online with 1st Domains at https://www.1stdomains.nz/register 

On the 1st Domains website, you need to type the domain name you wish to register into the "Search for your new domain" field then press "Search". 
  
This will list domains with the extension you were wanting plus other options. You can then see whether the domain is available to be registered. If it is, tick it and click "Register the selected domain name(s)". 
  
The next screen takes you to the options of creating a new account or using an existing account, if you do not already have an account with 1st Domains then press "Create account". 
  
You will now be prompted to enter your contact details and billing information. 

After completing all the fields press on "Continue". 
  
On the next screen if you are unsure of what to use for your "Name Server 1" and "Name Server 2" then just make sure the box labeled "Park Domain" is ticked and press "Continue" 
  
Next is the option to add web or email hosting to your order. You can "add to cart" or "continue without hosting". If you are unsure, you can always come back once the domain has been registered and purchase those options.
  
You will now be prompted to enter your credit card details, after you have completed all the fields on this page press "Process Order". 
  
Your domain name will then be registered and a confirmation email will be sent to you.
