If you are registering a domain for a New Zealand business, the first decision is usually the smallest-looking one: do you take yourbusiness.co.nz, yourbusiness.nz, or both? It is worth five minutes of thought, because the name you choose ends up on your vehicles, your invoices and your email address for years.
The short answer
If you are a New Zealand business selling to New Zealanders, .co.nz is still the safe default, and registering the matching .nz alongside it is cheap insurance. If you are starting fresh and want the shorter, more modern-looking address, .nz is a perfectly good primary choice — just take the .co.nz as well so nobody else can.
What each one actually means
Every domain ending in .nz is New Zealand’s country-code domain, overseen by the Domain Name Commission on behalf of InternetNZ. Underneath it sit the familiar second-level domains — .co.nz for commercial organisations, .org.nz for non-profits, .net.nz for network operators, .school.nz, .govt.nz and others.
Until 2014, .co.nz was effectively the only option for a business. Then registrations opened directly at the second level, so yourbusiness.nz became possible alongside yourbusiness.co.nz. Both are equally valid, both are equally trusted by search engines, and both are equally New Zealand.
.co.nz — the one people expect
Recognition is the whole argument, and it is a strong one. A generation of New Zealanders has been typing .co.nz since the 1990s. It is what customers guess when they cannot remember your exact address, what they expect to see on a van, and what they type when someone tells them your business name over the phone. If your customers skew older or your business is local and offline-first, that familiarity has real value.
.nz — shorter, and increasingly normal
Three characters shorter, which matters more than it sounds when your email address is being read out down a phone line or printed across the side of a trailer. It reads as current rather than dated. A decade after launch it no longer looks unusual, and plenty of well-known New Zealand brands now use it as their primary address.
.kiwi.nz and the rest
.kiwi.nz is a deliberate choice — playful, unmistakably local, and a good fit for tourism, hospitality and consumer brands with some personality. It is a poor fit if you need to be read as conservative and established, such as in professional services or finance. There is no wrong answer here, only a tone.
Why most businesses end up registering both
The reason is defensive, not technical. If you register only yourbusiness.co.nz, then yourbusiness.nz stays available to anyone — including a competitor, or someone who noticed your business doing well and would like you to buy it from them later at a price of their choosing.
Registering both costs roughly the price of a couple of coffees a month. Recovering a name someone else took, if it is even possible, costs vastly more in legal time and frustration. This is one of the few genuinely cheap risks to close in a business.
You do not need to build two websites. You point one at your site and set the other to redirect to it, so both addresses land in the same place. Any competent provider will do this for you, and registering both at once takes about as long as registering one.
Does the extension affect your Google ranking?
Not in the way people usually assume. Google treats .co.nz and .nz alike — both are recognised as New Zealand country-code domains, which helps you appear for searches from within New Zealand. Neither ranks above the other because of the letters after the dot.
What genuinely affects your ranking is what is on the site: whether your pages answer the questions people are actually searching, whether the site loads quickly, whether it works properly on a phone, and whether other New Zealand sites link to you. Choosing .nz over .co.nz will not move you up a single position. Publishing a page that properly answers a question your customers ask might.
Things worth knowing before you register
- There is no residency requirement. You do not have to be a New Zealand citizen or resident to hold a .nz domain, and you do not need a registered company. A sole trader can register one.
- You register, you do not buy. A domain is held for a term, typically one or two years, and lapses if it is not renewed. Set renewals to automatic. Expired domains are one of the most common and most avoidable ways businesses lose their website and email overnight.
- Check social handles at the same time. There is no point securing a domain if the matching name is taken on every platform you plan to use.
- Avoid hyphens and creative spelling. If you have to spell it out every time you say it aloud, it will cost you customers. Say the candidate name down a phone line to someone before you commit to it.
- Think about length in context. It has to fit on a business card, a van door and an email signature, and be typed correctly by someone on a phone with one thumb.
What about .com?
If you sell overseas, or plan to, a .com is worth having. For a business trading in New Zealand it is a supporting act rather than the headline. A .co.nz or .nz address tells a New Zealand customer immediately that you are local, that you charge in New Zealand dollars, and that you are in a workable time zone — signals a .com simply does not carry.
The common pattern is a .co.nz or .nz as the primary address, with a matching .com registered and redirected to it. If you later expand into Australia, the same logic applies to .com.au, which does have eligibility requirements .nz domains do not.
How to decide, in about a minute
- Search for your preferred name and see what is actually available. Many decisions get made for you here.
- If both .co.nz and .nz are free, take both. Pick whichever you prefer as the primary and redirect the other.
- If only one is free, take it. A working name today beats a perfect name you cannot have.
- If your business name is already taken by an unrelated business, adjust rather than fight. Adding your city or your trade often reads better anyway, and can help with local search.
