Equity Investment In New Zealand: Legal Considerations For Startups

Raising capital is exciting - until you realise that equity investment isn’t just “getting money into the business”. It’s a legal and commercial decision that can reshape who owns your company, who controls key decisions, and what happens if things don’t go to plan.

If you’re a startup founder or small business owner in New Zealand and you’re considering bringing in investors (whether friends and family, angels, or institutional investors), getting your legal foundations right from day one can save you serious time, cost, and stress later.

This guide is general information only and isn’t legal advice. Because fundraising rules can turn on the details (who you offer to, how you market, what you say, and the documents you use), it’s worth getting advice on your specific raise before you accept any money.

In this guide, we’ll walk you through what equity investment means in practice, the common deal structures you’ll see in NZ, and the key legal documents and laws to keep in mind before you take anyone’s money.

What Is Equity Investment (And Why Does It Matter For Your Business)?

Equity investment is where an investor puts money (or sometimes other value, like assets or services) into your business in exchange for an ownership interest - usually shares in a company.

Unlike a loan, an equity investment generally doesn’t come with a guaranteed repayment schedule. Instead, the investor’s “return” is tied to the success of your business, such as:

• future dividends (if your company pays them);
• selling their shares later (for example, at a higher price in a later funding round); or
• a business sale (trade sale) or other “exit”.

From your perspective as a founder, equity investment can be a great way to fund growth without immediate repayment pressure. But there’s a trade-off: you’re giving away a portion of ownership and (often) decision-making power.

That’s why the key question isn’t just “how much can we raise?” - it’s also:

• How much ownership are we giving up?
• What control rights is the investor asking for?
• What happens if we need to raise again?
• What happens if a founder leaves, or the business is sold?

These issues are usually governed by the Companies Act 1993, your company’s constitution and shareholder arrangements, and the specific investment documents you sign.

Is Your Business Ready For Equity Investment?

A lot of equity deals fall over (or become painful later) because the business wasn’t “investment-ready” from a legal point of view. The good news is that being ready is usually achievable - it just takes some structured prep.

1) Make Sure You’re Using The Right Business Structure

In New Zealand, most equity investment happens into a registered company (rather than a sole trader or partnership), because companies can issue shares and offer clearer ownership rules.

If you’re already a company, great. If not, you may need to incorporate before raising equity.

You’ll also want to consider whether your company should adopt or update a Company Constitution. A constitution can set rules around share issues, director powers, shareholder decision-making, and share transfers - and investors often expect one to be in place (or will require amendments as part of the deal).

2) Know Your Numbers (And Your Cap Table)

Before negotiating, you need a clean view of:

• who currently owns what (the cap table);
• how many shares exist and what rights they carry;
• any existing options, convertible instruments, or promised equity; and
• any debts or liabilities that could affect valuation.

Even in small businesses, it’s common to discover informal promises like “we’ll give you 5% later” or “you’ll get shares when we hit X milestone”. These can derail negotiations if they’re not documented properly.

3) Get Your Key Contracts And IP In Order

Investors are usually investing in your future value - and a big part of that is your contracts and intellectual property (IP).

Common issues investors look for include:

• IP not being owned by the company (for example, a founder personally owns the code or brand);
• missing agreements with contractors or developers; and
• unclear customer or supplier terms.

If your value relies heavily on IP (software, brand, product design, proprietary processes), it’s worth getting proper advice early - an Intellectual Property Lawyer can help you identify gaps and fix them before they become deal-breakers.

What Are The Common Equity Investment Structures In NZ?

Equity investment can be structured in a few different ways. The “right” structure depends on your stage, valuation certainty, investor expectations, and how quickly you need to move.

1) Straight Equity (Share Subscription)

This is the most direct option: the investor pays money and your company issues new shares to them.

Typically, this is documented in a Share Subscription Agreement, which sets out things like:

• how much is being invested;
• how many shares are issued and at what price;
• conditions that must be met before completion (if any); and
• warranties (promises) the company and founders make about the business.

This structure is common when you have a clear valuation and both sides are ready to settle terms.

2) Term Sheet First (Then Full Documents)

Many deals start with a high-level Term Sheet. This usually summarises the key commercial points before the parties spend time and money on the full legal documents.

Term sheets can be partly binding and partly non-binding, depending on how they’re drafted. It’s important not to treat them as “just a casual summary” - if the term sheet is vague or one-sided, it can shape the rest of the deal in ways that are hard to unwind later.

3) Convertible Instruments (Valuation Deferred)

Early-stage businesses sometimes use instruments that delay setting a valuation until a later funding round. Two common examples are:

• a Convertible Note (a debt instrument that can convert into shares later); and
• a SAFE Note (a market-style agreement designed to convert into equity in the future, typically without being structured as “debt”).

These instruments aren’t standard “one size fits all” statutory products in New Zealand - they’re commercial structures that need to be tailored to your company, your constitution, and the Companies Act 1993 requirements around issuing shares and director approvals.

They can help you move faster, but they still carry legal and commercial risk - especially around conversion triggers, discounts, valuation caps, what happens if you never raise another round, and whether the instrument behaves like debt in practice (including in downside scenarios).

From a founder perspective, the big watch-out is that “quick funding now” can quietly become “expensive dilution later” if the terms aren’t balanced.

4) Different Share Classes (Preference Shares)

Some investors will want a separate class of shares (often called “preference shares”) with special rights, such as:

• priority on exit proceeds (liquidation preference);
• anti-dilution protections;
• veto rights on major decisions; or
• enhanced information rights.

These are powerful terms. They can be reasonable in the right context, but they need to be clearly documented and reflected properly in your constitution and shareholder arrangements.

What Legal Documents Do You Need For An Equity Investment?

Equity investment is one of those areas where DIY templates can cause real damage. You’re not just signing a document - you’re setting the rules of your ownership and governance for years to come.

While every deal is different, here are the most common legal documents involved in an equity investment in New Zealand.

Shareholders Agreement

A Shareholders Agreement is one of the most important documents for equity investment. It usually covers:

• how major decisions are made (and what needs investor approval);
• board composition and director appointment rights;
• rules for issuing new shares (future fundraising);
• restrictions on selling shares;
• what happens if a founder leaves (good leaver/bad leaver concepts); and
• exit mechanics (drag-along, tag-along, and sale process rules).

Even if your investor is “friendly”, it’s still smart to document expectations clearly. Most disputes don’t happen because people were bad - they happen because people remembered things differently.

Share Subscription Agreement (Or Investment Agreement)

This is the main contract documenting the investment itself. It usually includes:

• the subscription amount and share issue details;
• conditions precedent (steps required before completion);
• warranties by the company and founders; and
• limits on liability and claim timeframes.

Company Constitution Updates

If your constitution doesn’t match the deal terms, you may need to amend it (or adopt one). Investors will often want constitutional rules that align with:

• share class rights;
• pre-emptive rights;
• director and shareholder powers; and
• transfer restrictions.

This is where your Company Constitution becomes practical, not just paperwork.

Board And Shareholder Resolutions

Issuing shares usually requires formal company approvals. Depending on your setup, you may need:

• director resolutions approving the share issue;
• shareholder resolutions (especially if required under your constitution or shareholder agreement); and
• updates to the share register and Companies Office filings.

Founder And Key Person Protections

Sometimes investors will require founders to sign additional documents, such as:

• vesting arrangements (so equity is earned over time);
• restraint and confidentiality provisions; and
• IP assignment confirmations.

These aren’t necessarily “bad” - they’re often about ensuring the business isn’t crippled if a key person walks away. But they should be proportionate and clear.

What Laws And Compliance Issues Should You Watch Out For?

Equity investment sits at the intersection of company law, contract law, and (sometimes) financial markets regulation. You don’t need to memorise the legislation, but you do need to know where the risk areas are so you can get advice early.

Companies Act 1993 (Share Issues And Director Duties)

The Companies Act 1993 governs how NZ companies issue shares and the duties directors owe to the company.

In simple terms, directors must act in the best interests of the company and comply with legal requirements when approving major transactions (including share issues). If shares are issued incorrectly, you can run into disputes later - especially if the company grows and future investors do deeper due diligence.

Fair Trading Act 1986 (Be Careful With What You Say)

When raising equity, you’ll probably share forecasts, customer numbers, pipeline details, and growth projections.

The Fair Trading Act 1986 can apply where statements are made “in trade” and are misleading or deceptive (or likely to mislead or deceive). Whether it applies in a particular capital raise can depend on the circumstances - and investor claims may also arise under other legal frameworks (including contract, misrepresentation, and securities law principles).

That doesn’t mean you can’t be optimistic - but you should make sure statements you make to investors are accurate, can be substantiated, and are properly caveated where needed.

This matters even more if an investor later claims they relied on certain statements when deciding to invest.

Financial Markets Conduct Act 2013 (Offers, Disclosure And “Wholesale” Investors)

If you’re offering shares or other financial products, the Financial Markets Conduct Act 2013 (FMCA) may apply. In broad terms, offers that are made broadly to the public (or advertised publicly) are more likely to be regulated offers with disclosure requirements (such as preparing a product disclosure statement and using a registered disclosure document), unless an exemption applies.

Many startup raises are structured to rely on exclusions or exemptions (for example, offers to “wholesale” investors, certain small/close offers, or through licensed crowdfunding platforms). The line between a private raise and a regulated offer can be easy to cross - particularly if you market widely, use social media advertising, or approach a large number of people.

This is an area where tailored legal advice is especially important, because the compliance requirements can be significant and depend heavily on the exact offer structure, how it’s promoted, and the type of investor.

Privacy Act 2020 (If You Share Personal Information In Due Diligence)

During investment discussions, you may share customer lists, employee details, or other personal information. The Privacy Act 2020 requires you to handle personal information carefully and only disclose it where you have a lawful basis.

A practical approach is to anonymise data where possible and use controlled data rooms with clear access rules.

Key Takeaways

• Equity investment isn’t just funding - it changes ownership, control, and your long-term options, so it’s worth getting the structure right early.
• Most startups and SMEs raise equity through a company, so make sure your business structure, share records, and governance are in good shape before you negotiate.
• Common NZ equity investment structures include straight share subscriptions, term-sheet led deals, and convertible instruments like a Convertible Note or SAFE-style agreement (which should be tailored for NZ, not treated as off-the-shelf “standard forms”).
• A strong Shareholders Agreement and fit-for-purpose Company Constitution can prevent disputes by setting clear rules for decision-making, future fundraising, and exits.
• Be careful with investor communications: misleading statements can create legal risk, and the FMCA may apply depending on who you offer to and how you promote the raise (including whether you’re relying on a “wholesale investor” exclusion or another exemption).
• Don’t rely on generic templates for investment documents - equity terms affect your business for years, so it’s worth getting them tailored to your deal and goals.
