NZ Company Formation FAQ: 15 Questions for Founders

Forming a company in New Zealand is fast, online, and inexpensive — but the rules under the Companies Act 1993 are specific, and a handful of common errors lead to delays or avoidable Registrar enquiries. This FAQ answers the fifteen questions NZ founders most often ask in 2026.

Q1. Who governs NZ company registration?

The Companies Office, a business unit of the Ministry of Business, Innovation and Employment (MBIE), administers the NZ Companies Register. The Registrar of Companies is the statutory officer responsible for registration, name reservation, annual returns, and enforcement under the Companies Act 1993.

Q2. Do I need a constitution?

Legally optional under Companies Act 1993, s.27. If a company does not adopt a constitution, the rights, powers, duties and obligations of the company, its board, each director, and each shareholder are those set out in the Companies Act 1993 itself (s.28) — particularly Schedules 1 and 2.

Most closely held companies adopt a short constitution to:

• Install pre-emptive rights on transfer of shares (modifying s.41);
• Restrict the issue of new shares (modifying ss.42–47);
• Define quorum and voting at board and shareholder meetings;
• Provide an indemnity and insurance regime (s.162).

A constitution is also nearly always required by external investors when an investment round closes.

Q3. How many directors and shareholders do I need?

At least one director and at least one shareholder — and they may be the same person. NZ permits a single-shareholder, single-director company.

Critical constraint: at least one director must satisfy s.10(d) — live in New Zealand or live in an enforcement country (currently only Australia) and be a director of a company registered there.

Q4. Can I be the sole director if I’m overseas?

Only if you satisfy s.10(d). A founder living in Singapore who is not a director of an Australian company cannot be the sole director of a NZ company. Either:

• Move to NZ (>183 days physical presence);
• Take a directorship in an Australian company while living in Australia; or
• Appoint a qualifying NZ-resident or AU-director-resident director alongside.

This is a hard statutory bar that cannot be waived.

Q5. What’s the difference between a NZ company and an Australian Pty Ltd?

Two big ones. First, NZ has no separation between “private” and “public” at registration — every company is just a company under the Companies Act 1993; reporting obligations are layered on top by the Financial Markets Conduct Act 2013 and the Financial Reporting Act 2013. Second, NZ’s residency requirement (s.10(d)) is at least one director, not a majority — Australia’s Corporations Act 2001 (Cth), s.201A requires at least one director ordinarily resident in Australia for proprietary companies, similar in spirit but different in detail.

Q6. What’s the cost?

GST is currently 15% under Goods and Services Tax Act 1985, s.8(1). The Schedule of Fees is at https://companies-register.companiesoffice.govt.nz/help-centre/managing-your-online-account/schedule-of-fees/.

Q7. How long does incorporation take?

A motivated solo founder with all information ready can incorporate end-to-end within a single business day. Online lodgement and instant Registrar review mean the Certificate of Incorporation is typically emailed within minutes once all director and shareholder consents are signed.

Q8. What’s an NZBN?

The New Zealand Business Number is the cross-government identifier for NZ businesses. For Companies Act 1993 companies, the NZBN is automatically issued at incorporation — there is no separate application.

The NZBN is the key that links the company to IRD, ACC, councils, and many private-sector services. https://www.nzbn.govt.nz/

Q9. Do I need an IRD number?

Yes. Although not a Companies Act 1993 step, every newly incorporated company must:

• Apply for an IRD number with Inland Revenue at https://www.ird.govt.nz/managing-my-tax/ird-numbers/ird-numbers-for-businesses-and-organisations.
• Register for GST if expected annual turnover exceeds NZ$60,000 (GST Act 1985, s.51).
• Register as an employer if hiring (PAYE).

For resident-director companies, the IRD number is typically issued same-day via myIR.

Q10. Can I use a postal box as the registered office?

No. Companies Act 1993, s.186 requires a physical NZ address as the registered office. Postal services seem more private, but s.186 does not allow them. Use a registered office service if confidentiality is needed — typically a law firm, accounting firm, or company secretarial service.

Q11. What happens if I don’t file an annual return?

Two stages. First, the Registrar will send reminders. If the return remains unfiled, the Registrar may remove the company from the register under s.318(1)(b) — typically after a notice period. Removal extinguishes the company; assets vest in the Crown as bona vacantia under s.324.

To restore, you must apply under s.328 (administrative restoration) or to the Court under s.329, paying the restoration fee of NZ$200 + GST. Far cheaper to file the NZ$49.74 + GST return on time in your assigned filing month.

Q12. What records does my company have to keep?

At a minimum:

• Share register (s.87);
• Register of directors (s.189);
• Minute book of shareholder and board meetings (ss.120, 153);
• Accounting records sufficient to enable financial statements (s.194). Must be kept for at least 7 years (s.194(3)).

The records can be kept at the registered office or at another notified place.

Q13. Can a foreign company “branch” into NZ instead of forming a subsidiary?

Yes. Overseas company registration under Part 18 of the Companies Act 1993 (ss.332–349). An overseas company carrying on business in NZ must register with the Registrar within 10 working days of starting (s.334). It is a different register from the NZ Companies Register.

Most operators prefer a NZ-incorporated subsidiary for liability ring-fencing and clearer customer-facing presence. The branch path is appropriate for short-term presence or where the parent’s existing identity is integral to the operation.

Q14. Can I change the company name later?

Yes. Companies Act 1993, s.23 allows a change of name by special resolution of shareholders (s.106 — 75% majority). The company files notice of change with the Registrar; the name change takes effect on the date the Registrar issues a new Certificate of Incorporation under s.24.

The company’s identity (and NZBN) is unchanged — only the name on the register. Existing contracts, IRD numbers, and bank accounts continue under the new name.

Q15. What about whenua Māori?

A Companies Act 1993 company is a separate corporate vehicle. If it intends to hold or operate on Māori freehold land, additional approvals from the Māori Land Court under Te Ture Whenua Maori Act 1993 may be required for any transfer or lease. Many founders working with iwi or hapū structure the venture as a joint venture — a Companies Act 1993 company alongside a Māori land trust — rather than the company holding the land directly.

The Companies Act 1993 incorporation step itself is the same; the additional layer is the relationship with the whenua and the trust deed. Te Tumu Paeroa (the Māori Trustee) at https://www.tetumupaeroa.co.nz/ is the central reference point for Māori land trust structures.

Bonus Q. What about Māori incorporations?

Māori incorporations are governed by Te Ture Whenua Maori Act 1993, Part 13 — a different statute and a different register, administered by the Māori Land Court rather than the Companies Office. Operators forming a Companies Act 1993 company alongside a Māori land trust should obtain specific information from Te Tumu Paeroa and the Māori Land Court.

Conclusion

NZ company formation is among the fastest and cheapest in the OECD — but the Companies Act 1993 has specific rules on director residency (s.10(d)), registered office (s.186), record-keeping (s.194), and annual returns (s.214). The Companies Office online portal at https://companies-register.companiesoffice.govt.nz/ handles incorporation in a single day for prepared founders. The NZBN is automatic; the IRD number is same-day; GST registration kicks in at NZ$60,000 turnover. Most founder errors fall in the s.10(d) directorship area — plan that first, and the rest of incorporation is straightforward.
