Audit Obligations in New Zealand for Overseas Owned Businesses

April 23, 2026 By Cynthia Forbes

Recently, New Zealand has made a deliberate move to attract more overseas capital. The Overseas Investment (National Interest Test and Other Matters) Amendment Act came into effect on 6 March 2026 to streamline screening processes, focusing more on sensitive transactions, which would ultimately make it simpler and faster to invest in New Zealand. What the reform does not change however, is the financial reporting and audit framework governing overseas-owned businesses already operating here.

If you’re already managing or thinking about opening an overseas -owned business in New Zealand, this article is for you. It outlines when an audit is required in New Zealand, how the rules apply to overseas owned and overseas incorporated entities, and the key issues overseas owners should be aware of.

What Does “Overseas‑Owned” Mean in New Zealand?

For New Zealand financial reporting purposes, overseas ownership generally refers to:

  • An overseas company registered on the New Zealand Overseas Register and carrying on business in New Zealand; or
  • A New Zealand incorporated company that is a subsidiary of an overseas parent.

Both structures are subject to specific audit and filing rules under the Companies Act 1993 and the Financial Reporting Act 2013.

When Is an Audit Required?

1. Large Overseas Companies

Every large overseas company is required to prepare audited financial statements and file them with the New Zealand Companies Office each year. An overseas company (or its New Zealand business) is considered “large” if any one of the following applies:

  • Assets Test: Total assets (including subsidiaries) were over $22 million. This must be true at the balance date for each of the last 2 accounting periods
  • Revenue test: Total revenue (including subsidiaries) was over $11 million. This must be true in each of the last 2 accounting periods
  • Additional rule: overseas companies (and their subsidiaries) are considered large if they have at least one subsidiary that qualifies as large

If these thresholds are met, an audit is mandatory, regardless of the level of activity in New Zealand.

2. New Zealand Subsidiaries of Overseas Parents

A New Zealand incorporated subsidiary of an overseas company is also subject to enhanced audit requirements.

If the subsidiary is classified as large, it must:

  • Prepare general purpose financial statements in accordance with XRB standards (typically NZ IFRS or NZ IFRS RDR); and
  • Have those financial statements audited by a qualified New Zealand auditor.

Unlike widely held New Zealand companies, overseas owned subsidiaries cannot opt out of audit under shareholder consent provisions.

3. Filing Obligations with the Companies Office

Where an audit is required, the following must generally be filed with the Companies Office within five months of balance date:

  • Audited financial statements of the overseas company or New Zealand subsidiary;
  • Group financial statements (if applicable); and
  • The auditor’s report.

If the New Zealand business itself is large, New Zealand branch or subsidiary financial information must be included, even where group accounts are prepared overseas.

Can Overseas Financial Statements Be Used?

In certain circumstances, overseas prepared financial statements may be accepted in New Zealand, but this is not automatic.

Possible concessions include:

  • Use of overseas GAAP where an exemption has been granted by the Financial Markets Authority (FMA);
  • Acceptance of overseas auditors in limited cases (commonly for listed or regulated overseas entities); or
  • Specific legislative exemptions (for example, certain Australian wholly owned entities).

However, exemptions are narrowly applied, and most privately owned overseas groups operating in New Zealand should expect to comply fully with New Zealand audit and reporting standards.

Who Can Perform the Audit?

Any statutory audit required under New Zealand law must be conducted by a qualified or licensed New Zealand auditor.

Key points include:

  • The engagement partner must be recognised under the Financial Reporting Act 2013;
  • Audit firms must also be appropriately registered; and
  • Overseas auditors cannot sign New Zealand audit opinions unless formally recognised in New Zealand.

This often requires coordination between group auditors overseas and a New Zealand audit firm.

Common Traps for Overseas Owners

Overseas owned businesses frequently encounter issues such as:

  • Assuming small New Zealand operations are exempt from audit (size is assessed on a group basis);
  • Missing filing deadlines due to overseas reporting timetables;
  • Preparing overseas GAAP accounts that do not meet New Zealand disclosure requirements; and
  • Underestimating the impact of acquisitions that immediately trigger “large” status.

Early advice and planning can significantly reduce compliance risk and cost.
