.nz extensions, including .co.nz, .org.nz and the short .nz, are
open to anyone. There is no local-presence or eligibility requirement:
search, register, done.
Buying one
Register from either site. On phas.nz prices show in NZD and the charge is made in NZD; on phas.au the same domains are priced in AUD. Everything else, including renewals, DNS and forwarding, is identical.
What comes with it
The same as every phas domain: a managed DNS zone set up automatically, free email forwarding, redirects and a parked page, and DNSSEC in one switch.
Renewals
.nz domains renew the same way as every other extension here. See
How domain renewals and billing work.
Doing business on both sides of the Tasman
A .com.au beside your .co.nz needs an Australian identifier such as an
ABN. We collect it at checkout and file it for you; see
.au domain eligibility.
