   .nz is the internet country code top-level domain (cctld) for new zealand. it is administered by internetnz through its subsidiary, nz registry services, with oversight and dispute resolution handled by the domain name commission ltd. registrations are processed via authorised registrars. as of march 2011 there were 433,183 registered .nz domains. == history == as with many long-standing domain registries the registry was maintained informally for some time. the first formally recognised administrative organisation was the university of waikato until the responsibility was delegated to internetnz when it was formed in 1995. prior to the current structure, the registry operator of .nz was domainz. historically, domainz was a subsidiary of internetnz which also operated as a registrar and vendor of other add-on services such as dns. this combination of a natural monopoly (the registry activities) and vertical integration (the registrar and other services) was seen by some as restricting competition so internetnz moved to separate the provision of registry services into a separate organisation with strong oversight. the final part of this transition process was the sale of domainz to melbourne it{{cite web | title=melbourne it buys nz domain inc
