Many SMEs only think about domains once a decade—then a renewal, transfer, or DNS change becomes urgent. This guide explains the moving parts without turning you into a network engineer.
What is a domain registrar—and why does ownership matter?
A registrar records who controls the domain. You want the business (or director) to hold the account credentials, not an employee’s personal email that might disappear. Losing registrar access is one of the most painful website emergencies.
What is DNS, in one paragraph?
DNS translates your domain into instructions: where the website is hosted, where email is delivered, and sometimes verification records for security tools. A small DNS mistake can take a site offline or break email—changes should be planned, not rushed.
Which DNS records do business owners hear about most?
| Record type | Typical use |
|---|---|
| A / AAAA | Points the website hostname to a server IP. |
| CNAME | Aliases one hostname to another (common for www). |
| MX | Tells the internet where to deliver mail. |
| TXT | Verification, SPF/DKIM/DMARC for email authentication. |
How should you handle business email?
Many NZ businesses use Microsoft 365 or Google Workspace for reliability and support. You can keep email separate from website hosting—often a good idea—provided DNS is configured correctly. If you rely on “free email forwarding”, understand limitations and deliverability risks.
What are common pitfalls?
- Letting a developer register the domain in their own account without transfer documentation.
- Changing nameservers blindly and accidentally breaking email.
- Ignoring renewal reminders until the domain enters redemption.
- Using personal Gmail for critical registrar 2FA recovery.
Need help tying website and DNS together?
For domain and hosting context from a NZ provider, see domain registration on NZDH—then keep your governance rules (ownership, access) in your own runbook.
Frequently asked questions
Should DNS be at the registrar or the host?
Either can work. Choose one “source of truth” and document it. Split-brain DNS changes cause mistakes.
How long do DNS changes take?
Propagation can be minutes to hours due to caching. Plan cutovers during low-risk windows.
What is WHOIS privacy?
It hides personal details in public listings. You still must maintain accurate legal ownership internally.
Choosing and protecting your .nz domain
Register through a reputable provider—often the same place that hosts your site. Enable auto-renew and registrar lock; expired domains get snapped up by speculators. InternetNZ governs .nz policy; registrars must follow their rules. Keep login credentials in a password manager, not a single staff member's inbox.
Separate concerns: you can register a domain at one company and point DNS elsewhere, but understand who controls each login. Our domain registration service keeps DNS records documented when we manage hosting.
Email that survives hosting changes
MX records route email. Before changing nameservers for a new web host, copy existing MX, SPF, and DKIM records. Test with a low-TTL window if your provider supports it—see nameserver changes without breaking email.
