The Best NZ Company Databases in 2026: What They Include and How to Use Them

New Zealand has a well-maintained public company register that makes it possible to track new business activity in near real-time. If you work in accountancy, insurance, IT, recruitment or any other service that businesses need, understanding what data is available can give you a meaningful edge over competitors who rely on referrals and word-of-mouth alone.

The official sources

Companies Office / Companies Register

The Companies Office maintains the definitive register of every NZ company. It is publicly searchable at app.companiesoffice.govt.nz and shows:

• Company name and number
• Registered office address
• Directors (names and appointment dates)
• Shareholders (for small companies, names and shares held)
• Constitution status
• Registration date and annual return month

The data is official and free, but the search tool is not designed for prospecting. You cannot filter by region, industry, or registration date, and there is no bulk export for service providers.

NZBN (New Zealand Business Number)

Every business in New Zealand has an NZBN, a unique identifier that also pulls in trading names, industry codes (ANZSCO), and sometimes contact details that the business itself has submitted. The NZBN API is free for developers, and it adds useful context including inferred industry classification that the Companies Register alone does not provide.

The contact data gap

Neither the Companies Register nor the NZBN includes verified email addresses or phone numbers for the vast majority of newly incorporated companies. A brand-new company has no web presence, no Google Business Profile, and no directory listing yet. The founding director is often the only point of contact, and their details are not part of the public record.

This is the core challenge for anyone trying to reach new NZ companies at the moment they are most likely to need services. The companies exist in the register, but reaching them requires additional research.

How contact data is discovered

The most effective approach is a waterfall of data sources:

1. The company website (if one exists already)
2. Google Business Profile (if the director has set one up)
3. The director’s existing businesses (if they are a serial director, the contact from a previous company often carries across)
4. Email pattern inference: if the domain is known, common patterns like info@ or contact@ can be MX-verified
5. Email finder tools like Hunter.io (paid, best used when a domain is known)

A newly incorporated company typically has none of these set up on day one. Within 30 days, many will have a website and a Google listing. The window for reaching founders before they have chosen their service providers is roughly the first 30 to 60 days.

What commercial tools add

FreshFirms combines the Companies Register data with automated contact discovery and runs this process every weekday. The result is a feed of newly incorporated NZ companies, enriched with whatever contact details can be found from public sources, delivered to subscribers each morning. About 10 to 12 percent of new companies have a discovered email or phone number within the first 14 days.

For accountants, that translates to roughly 15 to 20 reachable companies per month per major region. For a practice targeting Auckland, that is more than 150 warm outreach opportunities per year, each one a business that incorporated in the last 30 days and has not yet chosen an accountant.

Compliance note

First-contact prospecting to business entities is permitted under the NZ Unsolicited Electronic Messages Act 2007 (UEMA) where there is an inferred commercial relationship. A newly incorporated company is actively seeking service providers, which creates that inferred relationship. Every email should include a clear business identity and an unsubscribe mechanism.
