The short answer: pick a .co.nz that matches your trading name, is easy to say over the phone, and skips hyphens and clever spellings. Expect $25–$50 a year. And make sure it’s registered in your name — the domain, not the website, is the asset you can’t rebuild.
Why the ending matters more than people think
A domain is your address on the internet — and in New Zealand, the ending does quiet work before anyone reads your page. In InternetNZ’s 2025 research, 74% of businesses and 62% of consumers said they find a .nz address more trustworthy than the alternatives. It says local in one glance: local prices, local phone number, someone in your time zone answering it.
That trust now extends to machines. When AI assistants weigh which businesses to mention for “electrician in Napier”, a .co.nz with consistent NZ details is exactly the kind of corroborating signal they lean on — more on that in our AI search guide.
The exotic endings — .xyz, .site, .online — are cheap for a reason. They read as temporary to customers who’ve spent thirty years typing .co.nz.
Choosing the name: a five-minute checklist
- Match your trading name. The name on the van, the invoice and the domain should be the same words. Machines cross-checking your details agree with humans on this.
- Say it aloud, once. If you have to spell it or say “dash” (“harbour — that’s H-A-R-B-O-U-R — hyphen — plumbing”), keep looking. Radio-test it: could someone hear it once and type it right?
- Skip hyphens and numbers. They’re where typos live. “4” and “four” will split your customers in half.
- Suburb in the name? Only if you’ll never move. hamiltonsparky.co.nz is great until you’re serving Cambridge and Te Awamutu too. Region beats suburb; trade-plus-name beats both.
- Shorter wins, but clear beats short. greenscapes.co.nz beats gsl-landscaping-waikato.co.nz. But clearandlong beats short-and-cryptic.
Two dollars of prevention: before committing, search the name on Google and the Companies Register. Sharing a name with an established business — especially one with bad reviews — is a headache you can dodge today.
The ownership check that saves real grief
Here’s the part that actually costs NZ businesses money: domains registered in the wrong name. It happens innocently — a helpful web person registers it under their own account, an agency puts it in their company name, a mate sets it up with his email. Everything works fine until the relationship ends, the agency closes, or the mate stops answering texts. Then the address all your customers know is legally someone else’s.
Check yours right now: the Domain Name Commission’s lookup at dnc.org.nz shows the registrant of any .nz domain. It should be you or your company. If it isn’t, request a transfer this week, while everyone’s friendly.
This is why we’re explicit about it on LaunchPad: the .co.nz is registered in your name from day one, we pay the renewals while you’re subscribed, and if you ever cancel, the domain goes with you. A provider who resists putting the domain in your name is telling you something — listen to it.
What it should cost
A .co.nz from mainstream NZ registrars runs $25–$50 a year. Watch the renewal price, not the first-year teaser, and turn auto-renew on — expired domains get scooped by squatters within days, and buying your own name back is an ugly negotiation. Registrar account security matters more than people think too: that login controls your address on the internet, so give it a strong password and 2FA — it’s the crown-jewel account in our website security basics.
One domain is enough to start. The variations (.nz, common misspellings) are cheap insurance once the business is established, but they’re optional extras, not day-one requirements. Day one is: right name, right ending, right owner.
