Due diligence basics
How to check a company in New Zealand
Before you sign, pay or take on a new supplier, it pays to know who the company really is. Here is a simple order of checks that works for any New Zealand company.

Start with the legal entity, not the website
A trading name on an invoice or a website is not the same as the legal entity behind it. The first job is to find the registered company and its New Zealand Business Number (NZBN). That is the anchor every other check hangs off.
Once you have the legal name and NZBN, you can line up what they told you against what the public record says. A mismatch between the name on a contract and the name on the register is worth a question before you go further.
- Find the full legal name, not just the brand or trading name.
- Note the NZBN and company number.
- Check the entity type, for example a New Zealand limited company or an overseas company.
Check the company status
Status tells you whether the company is currently registered and able to trade, or whether something has changed. A company that is registered and in good standing is the normal case. Other statuses are factual flags that deserve a closer look.
If a company is in liquidation, in receivership, in voluntary administration, or has been removed from the register, that changes how you would deal with it. None of these on their own tell you the whole story, but they tell you to slow down and ask more.
Look at how long it has been around
Incorporation date is a simple signal. A company that has traded under the same entity for years is a different prospect from one registered last month. Neither is good or bad by itself, but age helps you set the right level of caution.
Watch for a brand that claims a long history while the legal entity behind it is new. Sometimes there is a clean explanation, like a restructure. Sometimes it is worth asking about.
Confirm the details match
Cross check the registered office and the addresses you have been given. Confirm the company you found is the one you are actually dealing with, especially where several companies share a similar name.
If you are about to pay an invoice, confirm the company on the invoice is the registered entity you expect, and confirm any change of bank details through a channel you already trust rather than by replying to the same email.
Invoice and payment redirection scams often rely on a name that looks almost right. Matching the legal entity and confirming bank details separately is a cheap habit that prevents an expensive mistake.
Set up monitoring for anything ongoing
A check is a snapshot. If you will deal with a company over months or years, the position can change after you first looked. Monitoring means you find out when something on the record changes, rather than finding out after it has cost you.
This matters most for suppliers you depend on, customers you extend credit to, and partners whose standing affects your own.
Questions and answers
Is it legal to check a New Zealand company?
Yes. Company registration details such as name, status, incorporation date and registered office are public records in New Zealand. Looking them up is a normal part of doing business.
How long does a basic company check take?
Doing it by hand across a few sources can take 20 to 40 minutes per company. A Checkbase report brings the public record together in one place so you can read it in a few minutes.
What is the single most useful thing to check?
The legal entity and its current status. Almost every other question becomes easier once you have the right registered company in front of you.
