The .nz domain is due to regain a working registry by midday today, when the new Domainz Registry System should be opened to the public.
Domainz, the national Internet registry owned by the Internet Society of New Zealand (Isocnz) has been unable to do business since 4pm Friday, when work began on transferring the old Waikato University register to a new system developed by Glazier System.
But problems over the weekend with registry data, and then power cuts, have delayed the switch to the new system.
Registrars were allowed to use the new system yesterday, when there appeared to still be problems logging in with new IDs and passwords and, in some cases, searching for domain names.
The results of a new name search are also accompanied by a list of "registrars" that includes companies - such as IDG Communications and Fletcher Challenge - with no interest in registering domain names for third parties.
