Eligibility & Restrictions

Open to anyone worldwide. No local presence or residency required. Registrants must be identifiable individuals (18+) or lawfully constituted entities.

Registration

1-10 years. Email verification required for new registrations; failure leads to suspension/deletion.

Transfer Procedure

UDAI (Unique Domain Authentication Identifier, 16 characters) — equivalent to auth code. No change to expiry date on transfer before expiry. Ownership change: both current and new registrant must complete written forms.

Terminology: 'UDAI' not 'auth code'. Important to communicate correctly with registrants.

📘 ICANN Transfer Policy (IRTP) — See ICANN Transfer Policy for the full IRTP framework, auth code rules, 60-day lock periods, and TEAC.

Registrant Change

Ownership change requires written confirmation from both current and new registrant. Form-based process.

📘 ICANN OwnerChange (COR) — See ICANN OwnerChange for COR triggers, FOA/DA modes, 60-day lock, and opt-out.

Renewal & Deletion

Standard. Email verification required; failure leads to suspension/deletion.

📘 ICANN ERRP — See ICANN ERRP for the standard gTLD expiry lifecycle (Auto-Renew Grace → RGP → Pending Delete → Released).

Restore / Redemption Grace Period

90-day RGP (one of the longest). No Pending Delete period after RGP.

📘 ICANN ERRP — See ICANN ERRP for RGP details and standard restore fees.

WHOIS / Privacy

IDN support added November 2022 (Māori language macrons). Standard WHOIS. Privacy services available via some registrars.

📘 ICANN Registration Data Policy — See Registration Data Policy for RDP 2025, RDAP, redaction defaults, and privacy/proxy rules.

NIS2 Compliance

N/A. New Zealand not subject to EU NIS2.

📘 NIS2 Compliance — See NIS2 Compliance for Article 28 requirements, registry implementation status, and operational impact.

Known Error Codes & Notes

Email verification: Email verification failure = domain suspension/deletion.
90-day RGP: Notably longer than most ccTLDs.
