Shareholder Loans In New Zealand: Key Legal Essentials

If you run a small company in New Zealand, there’s a good chance you’ve already come across shareholder loans - even if you didn’t call them that at the time.

Maybe you covered a supplier invoice from your personal account to keep cashflow moving. Maybe you injected money to get the business through a slow season. Or maybe you’re thinking about taking money back out after a profitable quarter.

Shareholder loans can be a practical way to fund (or withdraw funds from) a company. But they also sit right at the intersection of company law, tax, and record-keeping - which means if you don’t set them up properly, they can create confusion between owners, issues with IRD, and disputes when a shareholder exits or the business is sold.

Below we break down what shareholder loans are, how they work, and the key legal essentials to get right from day one.

What Are Shareholder Loans (And Why Do Small Businesses Use Them)?

A shareholder loan is money owed between a company and one of its shareholders. It can work in either direction:

• Shareholder to company: you personally lend money to the business (the company owes you).
• Company to shareholder: the company lends money to you (you owe the company).

In many small NZ companies, shareholder loans happen informally at first - because they’re convenient. Instead of going to a bank, you use your own funds to:

• pay startup costs (stock, equipment, website build, rent bond)
• cover temporary cashflow gaps
• fund growth (hiring, marketing, extra inventory)
• keep the company solvent while waiting on customer payments

On the flip side, owners sometimes take money out of the company as drawings, reimbursements, or “temporary advances” - and that can end up recorded as a shareholder loan from the company to the shareholder.

The important thing is this: once money moves between you and the company, you need to be able to clearly explain what it is. Is it a loan? Is it salary? Is it a dividend? Is it a reimbursement? The label matters because the legal and tax consequences can be very different.

Shareholder Loan vs Capital Injection (Shares)

One common point of confusion is the difference between lending money to the company and putting money in as equity.

• Loan: the company owes the shareholder and (usually) should repay it under agreed terms.
• Equity (shares): the shareholder owns more of the company, and the money is not repaid as a “debt” (returns generally come through dividends or sale value).

Deciding whether funding should be debt or equity often depends on your goals (repayment, risk, tax, investor expectations, and who controls the company). If you’re issuing shares or bringing in new investors, it’s worth getting your share structure clear early - including how decisions are made and what happens if someone wants out - often through a properly drafted Shareholders Agreement.

Is A Shareholder Loan Legally Binding In New Zealand?

Yes - a shareholder loan can be legally binding. But whether it’s enforceable in practice (and whether it’s treated the way you expect by IRD, your accountant, or other shareholders) depends heavily on documentation and conduct.

Even if a loan is verbally agreed, verbal arrangements can be messy when memories differ or circumstances change. For a company, the better approach is simple: write it down, document the key terms, and keep clean records.

Why Documentation Matters

A written shareholder loan record helps you show:

• who the parties are (the company and the shareholder)
• the amount advanced (or withdrawn)
• when it was advanced
• whether interest is payable
• when repayment is due (or how it will be repaid)
• what happens if the shareholder leaves or sells shares

Without clarity, shareholder loans can turn into shareholder disputes fast - especially where there are multiple owners, different financial contributions, or informal withdrawals over time.

Company Law Basics: The Company Is A Separate Legal Person

In NZ, once you operate through a company, the company is its own legal entity. That means:

• the company’s money is not “your money” (even if you own 100% of the shares)
• payments between you and the company should have a clear legal basis
• the company should keep proper accounting records and follow its governance processes

This separation is also why it’s important to have your internal rules sorted. Depending on how your business is set up, that might include a Company Constitution and shareholder arrangements about funding, repayments, and approvals.

What Terms Should A Shareholder Loan Agreement Include?

There’s no one-size-fits-all approach. A shareholder loan that’s meant to be repaid next month looks very different to a long-term funding arrangement that sits in the business for years.

That said, most shareholder loans should address a few core legal and commercial points.

Key Terms To Consider

• Loan amount: the principal sum (and whether further advances are allowed).
• Purpose (optional but helpful): what the loan is for (e.g. working capital).
• Interest: whether interest is payable and how it’s calculated.
• Repayment terms: on demand, by instalments, at a set date, or when the company is able.
• Priority: whether the loan ranks behind other creditors (for example, a bank) or is subordinated.
• Default: what happens if repayment isn’t made when due (and what remedies apply).
• Set-off: whether amounts can be offset against dividends, salary, expenses, or share sale proceeds.
• What happens on sale/exit: whether the loan must be repaid before shares are transferred, or whether it transfers with the shares.

If your company has more than one shareholder, it’s also smart to ensure the broader governance documents match what you’re doing in practice. For example, if one shareholder is funding the business and another isn’t, you may want written rules on how that affects profit distributions, decision-making, and exit outcomes (often covered in a shareholders agreement).

Do You Need Security For A Shareholder Loan?

Sometimes. In many owner-managed businesses, shareholder loans are unsecured because the shareholder is comfortable taking the risk.

But there are scenarios where it’s worth thinking about security (especially if the amounts are significant), such as:

• where a shareholder is lending substantially more than others
• where the company has valuable assets and the shareholder wants protection
• where the business has external creditors and risk is higher

In those cases, a security arrangement may be appropriate. This is a technical area, so it’s worth getting advice to ensure the security is properly documented and registered if needed.

Common Legal And Tax Risks With Shareholder Loans (And How To Avoid Them)

Shareholder loans are common - but they’re also one of the areas where small businesses can accidentally create risk without realising it.

Here are some of the most common issues we see.

1. Treating Withdrawals Like “Free Money”

If you take money from the company without documenting it as salary, a dividend, or reimbursement, it often ends up as a shareholder loan from the company to you.

That might be fine - but it needs to be recorded and managed. If it grows over time, it can raise tax issues and create awkward conversations with other shareholders (or a buyer doing due diligence).

2. Not Charging Interest (When It Should Be Considered)

Whether or not interest should be charged depends on your circumstances - including tax considerations and commercial fairness (especially in multi-shareholder companies).

If interest is charged, you’ll want clarity on:

• the interest rate
• how/when it’s paid (monthly, quarterly, capitalised)
• how it’s recorded in the accounts

If interest is not charged, you still want that clearly recorded so nobody later argues that interest was implied.

3. Solvency, Related-Party Decisions, And Director Duties

Directors have duties under the Companies Act 1993, including duties relating to acting in good faith, exercising care and diligence, and avoiding reckless trading.

From a practical perspective: if the company is struggling financially, paying out shareholder loans (or making loans to shareholders) can be risky. Even though a loan isn’t the same thing as a “distribution” (like a dividend, which must meet a solvency test), directors still need to consider the company’s solvency and whether entering into (or repaying) a related-party loan is in the company’s best interests and consistent with proper governance.

Also, where the borrower or lender is a director (or a director-related person), you may need additional governance steps - for example, managing conflicts of interest, recording the director’s interest, and ensuring the decision is properly approved and documented. Depending on your constitution and circumstances, shareholder approval or additional disclosure steps may also be relevant.

This is one of those areas where getting advice early can save you serious headaches later - especially if you’re restructuring funding, reducing costs, or trying to keep the business afloat.

4. Messy Records (And Painful Due Diligence Later)

Shareholder loans often come under the microscope when:

• you’re selling the business
• bringing on a new shareholder/investor
• refinancing with a bank
• a shareholder relationship breaks down

If your books show a large shareholder loan balance with no clear paper trail, it can slow down the transaction or reduce the value of your business (because the buyer may see it as a liability that needs to be repaid at settlement).

If selling the business is on your radar, it’s worth tightening this up well before you go to market, and having a clear process for how the loan will be dealt with in the transaction documents (often alongside an Asset Sale Agreement or other sale structure).

5. Mixing Shareholder Loans With Salary, Dividends, And Expenses

It’s normal in a small business to have multiple ways money moves between owners and the company. The key is to keep them distinct. For example:

• Salary/wages: paid as employment income (and should be documented properly).
• Dividends: paid to shareholders in proportion to shareholding (subject to solvency and shareholder resolutions).
• Reimbursements: repayment of genuine business expenses personally paid.
• Loan repayments: paying back principal (and possibly interest) under a loan arrangement.

If you’re paying a working owner a wage, it’s worth making sure you have the right paperwork in place, including an Employment Contract where appropriate, so there’s a clear employment vs shareholder boundary.

How Do Shareholder Loans Work When There Are Multiple Shareholders?

Once you have more than one shareholder, shareholder loans can become sensitive - not because they’re “bad”, but because they directly affect fairness and control.

Here are a few common multi-shareholder scenarios:

One Shareholder Funds The Business More Than The Others

This often happens in startups and family businesses. For example, one founder can afford to inject cash, while the other contributes time, skills, or IP.

A shareholder loan can be a fair way to recognise the cash contribution without immediately changing share ownership - but you’ll want to be clear about:

• whether the loan is repayable before profits are distributed
• whether interest is payable
• what happens if the company can’t repay
• what happens if a shareholder wants to leave

This is where a properly structured shareholder relationship becomes important. If you’re allocating rights and obligations between owners, a Founders Agreement can also be helpful early on (before things get complicated), especially if roles and contributions are still evolving.

Shareholder Loans And Decision-Making

Even if you’re the major lender to the company, that doesn’t automatically give you extra voting power (votes usually attach to shares, not loans).

If you want certain “protections” as a lender (for example, requiring approval before the company takes on other debt, or restricting major spending), you might need to document that separately as part of your governance arrangements.

When A Shareholder Leaves Or Sells Shares

This is where shareholder loans often cause the biggest surprises.

Imagine this: you and a co-founder each own 50% of a company. You’ve lent the company $80,000 over two years. Your co-founder decides to exit and sell their shares. If your shareholder loan hasn’t been documented clearly, you can end up in a dispute about:

• whether the loan is real and repayable
• whether it should be repaid before the share sale completes
• whether the loan reduces what the business is “worth”
• whether the exiting shareholder is entitled to half the value of a business that is still indebted to you

Good agreements don’t just protect you - they protect the relationship by setting expectations early.

Practical Steps To Get Shareholder Loans Right From Day One

You don’t need to overcomplicate shareholder loans, but you do want to be consistent and intentional. Here’s a practical checklist to help you stay protected.

Step-By-Step Checklist

1. Decide what the payment is before money moves: loan, salary, dividend, reimbursement, or equity.
2. Record it properly in your accounts (your accountant can help set up the right ledger entries).
3. Put key terms in writing so everyone understands repayment expectations and interest (if any).
4. Make sure director approvals and governance processes are followed, especially where a director or shareholder is on the other side of the transaction.
5. Keep supporting evidence like bank transfer references, invoices (for reimbursements), and board/shareholder resolutions where needed.
6. Align your shareholder funding approach with your wider documents (constitution, shareholder arrangements, and any exit terms).

It can feel like “admin”, but it’s the kind of admin that prevents expensive clean-up later - especially if you raise capital, sell, or end up in a disagreement with a co-owner.

Key Takeaways

• Shareholder loans are a common and practical way for NZ small businesses to fund operations or manage owner withdrawals, but they need to be clearly identified and recorded.
• A shareholder loan can go either direction (shareholder-to-company or company-to-shareholder), and each has different legal and tax risks.
• Getting the loan terms in writing (amount, repayment, interest, and what happens on exit) helps prevent disputes and supports enforceability.
• In multi-shareholder companies, shareholder loans can create fairness and valuation issues if they aren’t aligned with your governance documents and exit arrangements.
• Director duties and solvency matter - even where a transaction is structured as a loan, directors should ensure it’s properly approved, documented, and appropriate for the company’s financial position.
• Clean records make future events (like selling the business, bringing in investors, or refinancing) much smoother and can protect the value of your company.

Important: This article is general information only and isn’t tax advice. Shareholder loans can have tax consequences depending on how they’re structured and recorded, so it’s worth speaking with your accountant and checking IRD guidance for your specific situation.
