How to Register a Company in New Zealand: Complete Guide 2026 (Companies Office, NZBN, IRD)

Last verified: 2026-05-02 Author: MmowW Scrib🐮 — Document Preparation Service operated by a Gyoseishoshi (行政書士) office in Japan Primary sources: companiesoffice.govt.nz · legislation.govt.nz · business.govt.nz · ird.govt.nz · mbie.govt.nz

Registering a company in New Zealand is one of the fastest, cleanest incorporation processes anywhere in the OECD. A motivated solo founder with all information ready can move from idea to Certificate of Incorporation and NZBN within a single business day, end-to-end, online, for under NZ$130 + GST. But “fast” does not mean “simple”: the Companies Act 1993 (No 105) imposes a hard set of statutory requirements — at least one qualifying resident director under s.10(d), a physical NZ registered office under s.186, prescribed director and shareholder consents under s.12, and an immediate set of post-incorporation obligations covering IRD numbers, GST, and KiwiSaver if you intend to hire. This pillar guide walks through every step, every requirement, every fee, and every common mistake from a Gyoseishoshi document-preparation perspective. By the end you will know exactly what to prepare, what to file, what to expect from the Companies Office Registrar, and what to do in the first 30 days after the certificate lands in your inbox.

Quick Answer (TL;DR)

To register a New Zealand limited liability company in 2026 you must (i) reserve a proposed name with the Companies Office (NZ$10 + GST, valid 20 working days under s.23), (ii) submit an online application via the NZ Companies Register paying the NZ$118.74 + GST incorporation fee, (iii) collect electronic consents from every director (s.12(1)(b)) and every shareholder (s.12(1)(d)), (iv) appoint at least one director who lives in New Zealand or in an enforcement country (Australia) and is also a director of an Australian-registered company (s.10(d)), (v) provide a physical NZ registered office (s.186), and (vi) once the Registrar issues your Certificate of Incorporation under s.12, immediately apply for an IRD number, register for GST if your turnover will exceed NZ$60,000 (Goods and Services Tax Act 1985, s.51), and set up your share register, register of directors, and minute book under ss.87, 189 and 215. The whole process is online, paperless, and typically takes a few hours of active work plus a 1–3 day window for consent signatures.

1. Overview

The Companies Office, a business unit of the Ministry of Business, Innovation and Employment (MBIE), administers the New Zealand Companies Register. The Registrar of Companies is the statutory officer with sole authority to register, dissolve, and enforce filings under the Companies Act 1993. Every New Zealand limited liability company in operation today — from a one-person Wellington SaaS startup to a listed FMC reporting entity — is registered with this single Registrar through this single online portal: https://companies-register.companiesoffice.govt.nz/.

Under New Zealand law a “company” is a body corporate registered under the Companies Act 1993 (s.10). The default and almost universal form for trading entities is a company limited by shares. Once registered, the company has separate legal personality (s.15), the capacity, rights, powers and privileges of a natural person (s.16), perpetual succession (s.15(2)), and shareholder liability is limited to the amount unpaid on shares (s.97).

Unlike many other common-law jurisdictions, NZ does not distinguish between “private” and “public” companies at registration. The same Companies Act 1993 applies to all companies — additional reporting obligations attach later if the company becomes an FMC reporting entity under the Financial Markets Conduct Act 2013 or a “specified” entity under the Financial Reporting Act 2013. For 95%+ of founders this distinction never matters: the company they register is and remains a closely held, privately owned vehicle.

NZ has no separate “Pty Ltd” suffix as in Australia, no “GmbH” as in Germany, no “SARL” as in France. The required suffix on every NZ company is “Limited” or its abbreviation “Ltd” (Companies Act 1993, s.20). That single word, placed at the end of the chosen name, is what tells the public — and the courts — that liability is limited.

2. Legal Foundation

The primary statute is the Companies Act 1993 (No 105), consolidated as at 1 July 2025. The full text is available at https://www.legislation.govt.nz/act/public/1993/0105/latest/whole.html. Five further Acts cross-cut into incorporation and immediate post-incorporation:

Director’s duties under ss.131–138 attach from incorporation — duty to act in good faith and in the best interests of the company (s.131), duty to exercise powers for proper purpose (s.132), duty to comply with the Act and the constitution (s.133), the reckless trading prohibition (s.135), the duty of care (s.137). These duties are mandatory under s.30 — a constitution cannot contract out of them. Founders sometimes wonder whether to “ease into” director responsibilities; legally there is no easing in. From the moment the certificate is issued, you are bound.

2.1 Te reo Māori, whenua, and tikanga considerations

Founders working with iwi, hapū, or whānau on whenua Māori (Māori freehold land) should be aware that incorporation under the Companies Act 1993 does not affect underlying Māori land rights. Where a venture intends to hold or operate on Māori land, additional approvals under Te Ture Whenua Maori Act 1993 may apply for transfers or leases — these are administered by Te Kooti Whenua Māori (the Māori Land Court), not the Companies Office. In practice many such ventures use a Companies Act 1993 company alongside a Māori land trust, with the company providing the operational vehicle and the trust holding the whenua. The corporate registration step is the same as for any other founder; the additional Te Ture Whenua layer sits beside it. Te Tumu Paeroa (the Māori Trustee) at https://www.tetumupaeroa.co.nz/ is the starting point for whenua-related due diligence.

2.2 Regulatory change monitoring

The Companies Office publishes registry updates at https://www.companiesoffice.govt.nz/news/. MBIE publishes consultation papers on Companies Act 1993 amendments at https://www.mbie.govt.nz/business-and-employment/business/regulating-entities/. Operators forming long-life vehicles (a holding company expected to last decades) should bookmark both pages — minor amendments to ss.214 (annual returns) and 159 (director changes) have occurred several times in recent years.

3. Key Decisions to Make Before You File

Before you touch the Companies Office portal, three structural decisions need to be made — and they are far cheaper to make right the first time than to amend later by special resolution under s.106.

3.1 Structure: limited liability company vs alternatives

A NZ limited liability company is the right answer for the overwhelming majority of trading ventures because of liability ring-fencing (s.97), tax efficiency (one corporate income tax rate of 28%), and credibility with banks, insurers, and customers. Alternatives — sole trader, partnership under the Partnership Law Act 2019, limited partnership under the Limited Partnerships Act 2008, branch of an overseas company under Part 18 of the Companies Act 1993 — are appropriate in narrower circumstances. Sole trader has zero registration cost but zero liability protection. Branch (overseas company) is appropriate where an existing overseas parent prefers to extend its own legal personality into NZ rather than create a separate subsidiary; it requires registration under s.334 within 10 working days of starting to carry on business in NZ.

3.2 Director residency — the s.10(d) question

This is the single most common stumbling block for international founders. Section 10(d) of the Companies Act 1993 requires that a NZ company must have at least one director who lives in New Zealand, or lives in an “enforcement country” and is also a director of a company registered in that enforcement country. The only currently designated enforcement country is Australia (Companies Act 1993 (Enforcement Country) Order 2015).

The Registrar’s working test for “lives in New Zealand” is physical presence in NZ for more than 183 days in a 12-month period. Less than 183 days may still satisfy the test in particular circumstances, but the Registrar may request further information. In practice the 183-day threshold is the safe harbour.

Practical decision points:

• 100% NZ-resident founders → no issue, sole director satisfies s.10(d).
• One NZ-resident, one overseas → the NZ-resident is the qualifying director.
• One Australian-resident who is also a director of an Australian-registered Pty Ltd → satisfies s.10(d) via the enforcement-country pathway.
• 100% non-NZ/non-AU → must appoint a qualifying NZ-resident director (a real director with real substance — a token directorship that does not satisfy the 183-day test risks Registrar enquiry).

This is a hard statutory bar. Constitution cannot waive it. No fee will accelerate it. Plan accordingly.

3.3 Constitution — adopt one or rely on default rules

Under s.27, a company may have a constitution. Under s.28, if it does not, the rights, powers, duties, and obligations of the company, the board, each director, and each shareholder are those set out in the Companies Act 1993 itself — Schedules 1 and 2 in particular.

A constitution may modify default Act provisions (s.31), subject to the mandatory provisions under s.30 (directors’ duties, prohibition on share buyback funded by trading insolvency, and so on) which cannot be contracted out of.

For closely held companies, a typical constitution installs:

• Pre-emptive rights on transfer of shares (modifying s.41 default)
• Restrictions on issue of shares (modifying ss.42–47 default)
• Customised quorum and voting rules (modifying Schedules 1 and 2)
• Indemnity and insurance for directors (s.162)

A 2026 founder planning to bring in investors within 12–24 months should adopt a constitution at incorporation — disapplying the s.41 pre-emptive right so the board can issue shares to incoming investors without first offering them to existing shareholders, and defining share classes if preference, redeemable, or non-voting shares are envisaged. Doing this at incorporation is far cheaper than amending later by special resolution.

4. Required Documents and Information

Section 12 of the Companies Act 1993 prescribes the documents that must accompany an application for registration:

4.1 Director consent (s.12(1)(b))

Every person named as a director must sign and return a written consent in the prescribed form before incorporation can proceed. The consent certifies that the person is not disqualified under s.151 — that is, not (a) under 18, (b) an undischarged bankrupt, (c) prohibited under ss.382, 383, or 385, (d) prohibited under the Takeovers Act 1993 / Financial Markets Conduct Act 2013 / Securities Markets Act 1988, (e) subject to a property order under the Protection of Personal and Property Rights Act 1988, or (f) disqualified by court order under any other Act.

4.2 Shareholder information

For each initial shareholder the application must record full legal name, residential address, number of shares held, and class of shares (if more than one class). Section 36 prescribes that shares must be issued for consideration that the board considers fair and reasonable to the company and existing shareholders.

4.3 Registered office and addresses

Three statutory addresses are required (ss.186–187A):

• Registered office (s.186): must be a physical address in New Zealand. A postal box is not acceptable. Every legal document of any consequence — court process, Inland Revenue notices, Registrar enquiries — may be served at this address.
• Address for service (s.187): must be a physical address; legal documents may be served here.
• Address for communication (s.187A): may be electronic; used for routine correspondence.

A change of registered office takes effect 5 working days after notice is given to the Registrar (s.186(2)).

5. Step-by-Step Process — Companies Office Online

The Companies Office operates a fully online registration system. There is no paper-based incorporation pathway for ordinary companies in 2026.

Step 1 — Create a RealMe / Companies Office Online Services Account

Go to https://companies-register.companiesoffice.govt.nz/, click Login → Create an account, and authenticate via RealMe (NZ government identity service) or create a Companies Office login. Verify the email address. RealMe reduces friction at later steps including IRD onboarding, so most founders prefer it.

Reference: https://companies-register.companiesoffice.govt.nz/help-centre/managing-your-online-account/setting-up-your-online-services-account/

Step 2 — Reserve the company name (s.22)

From the dashboard, select Reserve a company name. Enter the proposed name (e.g. “Aroha Holdings Limited”). The registry automatically checks availability against the Companies Register and the Trade Marks Register. Pay the prescribed fee (NZ$10 + GST). Reservation is valid for 20 working days (s.23).

A name will be refused if it is identical or almost identical to an existing registered name (s.22(1)(b)) or is offensive (s.22(1)(d)). You may also reserve a name with a Te Reo Māori spelling — kia ora to founders proudly choosing names like “Whenua Tech Limited” or “Tāmaki Manaaki Limited” — these are registered the same as any other name, with the spelling exactly as chosen.

Practical tip: search the existing register at https://app.companiesoffice.govt.nz/companies/app/ui/pages/companies/search before reserving. Even though the system runs an automated check, a human review of similar names will save you a refusal.

Step 3 — Apply to incorporate

Once a name is reserved, the system unlocks the Apply to incorporate workflow:

1. Confirm the reserved name
2. Enter registered office address (must be a physical NZ address — s.186)
3. Enter address for service and address for communication
4. Add directors: name, date of birth, place of birth, residential address
5. Confirm director qualification under s.151 (residency, not disqualified)
6. Add shareholders: name, address, shares held
7. Choose: with or without constitution (if with, upload PDF)
8. Declare ultimate holding company (if any — s.13(1)(b))

Step 4 — Send consent forms to directors and shareholders

The system automatically emails each director a director consent link, and each shareholder a shareholder consent link. Each person must click the unique link, authenticate, and sign electronically.

The application cannot be completed until every director and shareholder has signed. This is the most common cause of delay — a 24-hour gap while a co-founder finds time to authenticate. Send the application in the morning, follow up that afternoon.

Step 5 — Pay the incorporation fee and submit

After all consents are received, the applicant pays the incorporation fee NZ$118.74 + GST. The Registrar reviews the application — usually electronically — and, if satisfied, issues the Certificate of Incorporation under s.12. The certificate is conclusive evidence of incorporation (s.14). The company exists from the date shown on the certificate.

Step 6 — Receive certificate and NZBN

Within minutes (typical) to one working day, the certificate is emailed to the registered email address. A New Zealand Business Number (NZBN) is automatically issued at the same time. The NZBN is the unique identifier for the company across NZ government systems — Inland Revenue, ACC, Customs, banks, government procurement.

6. Costs and Timeline

6.1 Government fees (Schedule of Fees, Companies Office)

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

6.2 Indicative timeline

A motivated solo founder with all information ready can incorporate end-to-end within a single business day. A two-founder team where one founder is in a different time zone realistically completes within three working days.

7. Common Mistakes (Gyoseishoshi Perspective)

Across hundreds of NZ incorporations prepared in our document workflow, ten patterns repeat:

1. Naming a non-resident as sole director. Founder lives overseas, did not realise s.10(d) is mandatory. Either appoint a qualifying NZ/AU resident director or use a NZ resident director who is also a director of an Australian company. There is no waiver.

2. Using a postal box as registered office. Postal services seem more private. Section 186 requires a physical NZ address. Use a registered office service if confidentiality is needed — many NZ accounting practices and corporate services firms offer this.

3. Submitting the application before all consents are signed. The applicant rushes to pay. Confirm all directors and shareholders have completed the consent link before paying the incorporation fee.

4. Choosing a name almost identical to an existing company. Limited name research. Search the register at https://app.companiesoffice.govt.nz/companies/app/ui/pages/companies/search before reserving.

5. Forgetting to file return of allotment within 10 working days. Operational oversight. Diary the filing date as soon as new shares are issued (s.47).

6. Treating the constitution as optional and ignoring default rules. Misunderstanding of s.28. Read Schedules 1 and 2 of the Companies Act 1993 — if you do not adopt a constitution, those default rules govern your company.

7. Failing to apply for IRD number after incorporation. Assuming incorporation includes tax setup. Apply via myIR or Inland Revenue separately at https://www.ird.govt.nz/managing-my-tax/ird-numbers/ird-numbers-for-businesses-and-organisations.

8. Mis-stating director residential address. Privacy concerns. Residential address is required by s.151A — it appears on the public register. Consider this before naming a director, especially for high-profile individuals.

9. Missing the annual return filing month. No diary system. The Companies Office sends an email reminder, but the obligation is on the company. File before the last day of the filing month.

10. Issuing shares without board approval. Founders treat issue as automatic. Section 42 requires board resolution. Document it in the minutes.

8. After Completion — First 30 Days

Once the certificate of incorporation is issued, a sequenced post-incorporation programme is required.

Day 0–1

• Receive certificate of incorporation (s.14) and NZBN
• Set up the share register (s.87) — initial entries
• Set up the register of directors (s.189)
• Open the minute book

Week 1

• Apply for IRD number for the company via Inland Revenue myIR (https://www.ird.govt.nz/managing-my-tax/ird-numbers/ird-numbers-for-businesses-and-organisations)
• Open a NZ business bank account — banks require certificate of incorporation, IRD number, and AML identification of directors and shareholders
• Register for GST if required (turnover ≥ NZ$60,000 expected — GST Act 1985, s.51) at https://www.ird.govt.nz/gst/registering-for-gst
• Register as an employer (PAYE) if hiring (https://www.ird.govt.nz/employing-staff)

Month 1–3

• Adopt formal board minutes for share issuance (s.42), appointment of officers, banking authorities
• Put accounting system in place for financial records (s.194 — records must be kept at least 7 years)
• Confirm whether the company is a “specified” entity under the Financial Reporting Act 2013 requiring filed financial statements

Annual

• File annual return in the assigned filing month (s.214) — NZ$49.74 + GST
• Maintain registers up to date

Triggered events

• Issue of new shares → return of allotment within 10 working days (s.47)
• Change of director → notify Registrar within 20 working days (s.159)
• Change of registered office → 5 working days’ notice (s.186(2))
• Change of constitution → file amended document (s.32)

9. FAQ

Q1. Can I incorporate with just one shareholder and one director? Yes. New Zealand permits a single-shareholder, single-director company. Section 10 only requires at least one director and at least one shareholder, and they may be the same person.

Q2. Do I really need a constitution? Legally optional under s.27. If you adopt none, s.28 says the Companies Act 1993 default rules govern the company — Schedules 1 and 2 in particular. Most closely held companies adopt a short constitution to install pre-emptive rights on transfer, restrict share issues, and handle deadlock cleanly.

Q3. What if I want to bring in an investor in 6–12 months? Plan at constitution stage. Disapply the s.41 pre-emptive right so the board can issue new shares to incoming investors without first offering them to existing shareholders, and define share classes if you envisage preference shares, redeemable shares, or non-voting shares (s.36). Far cheaper than amending later by special resolution.

Q4. What records does the company actually have to keep? At minimum: share register (s.87), register of directors (s.189), minute book of shareholder and board meetings (ss.120, 153), and accounting records sufficient to enable financial statements (s.194). Accounting records must be kept for at least 7 years (s.194(3)).

Q5. What happens if I never file an annual return? The Registrar will send reminders. If unfiled, the Registrar may remove the company from the register under s.318(1)(b). Removal extinguishes the company; assets vest in the Crown as bona vacantia (s.324). To restore, apply under s.328 (administrative restoration) or to the Court under s.329, paying the restoration fee. Far cheaper to file the NZ$49.74 + GST return on time.

Q6. How does NZ company formation compare to Australian Pty Ltd? Two big differences. First, NZ has no separation between “private” and “public” at registration — every company is just a company; 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 s.201A requires at least one director ordinarily resident in Australia for proprietary companies, similar in spirit but different in detail.

Q7. Can a foreign company “branch” into NZ instead of forming a subsidiary? Yes — this is the 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 to carry on business (s.334). Most operators prefer a NZ-incorporated subsidiary for liability ring-fencing and clearer customer-facing presence — the branch route is appropriate where the foreign parent specifically wants to extend its own legal personality.

Q8. Can I change the company name later? Section 23 allows a change of name by special resolution of shareholders (s.106). 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.

Q9. How does incorporation interact with 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. The Companies Act 1993 step is the same; the additional layer is the relationship with the whenua and the trust deed.

Q10. Does Scrib🐮 actually do this end-to-end for me? Scrib🐮 prepares your incorporation documents — application content, draft constitution, director and shareholder consents, post-incorporation share register and minute book templates. The submission to the Companies Register is operator-completed via the Companies Office online portal — that is a personal authentication step that no third party can perform on your behalf. Scrib🐮 walks you through the portal screen-by-screen in the submission guide.

10. Conclusion

New Zealand company formation in 2026 is one of the cleanest incorporation processes in the OECD: an entirely online flow administered by a single Registrar, a single statute, a single set of forms, and a fee structure under NZ$130 + GST. The two genuine choke points are director residency under s.10(d) and the s.63A-equivalent practice of collecting consents before paying the fee — both predictable, both manageable with an hour of planning.

What looks deceptively simple at the registration step becomes complex in the months that follow: the seven-year accounting record obligation under s.194, the 10-working-day return-of-allotment trap under s.47, the annual return diary discipline, and the cumulative weight of ss.131–138 directors’ duties. Founders who treat incorporation as the finish line typically discover, around month 14, that they missed something. Treating it as the start of a structured 30-day, 12-month, and ongoing programme is the difference between a healthy company and a Registrar enquiry.

If you can describe your structure in two sentences, name your directors and shareholders confidently, and produce a physical NZ address that satisfies s.186, you can register your company before lunch tomorrow. If any of those three are still in flux, fix them first — the NZ$118.74 + GST is small; the cost of an unwound, misaligned, or non-compliant structure is large.
