Partnership Pros And Cons In New Zealand: A Legal Perspective

If you’re starting a business with someone you trust, a partnership can feel like the “obvious” choice. It’s flexible, it’s relatively simple to set up, and it lets you combine skills, contacts and capital from day one.

But partnerships can also come with big legal and financial risks - especially if you don’t put the right agreements (and expectations) in writing early on.

In this guide, we’ll walk you through the advantages and disadvantages of a partnership from a New Zealand legal perspective, so you can choose the structure that actually fits the way you want to run (and grow) your business.

What Is A Partnership In New Zealand (Legally Speaking)?

In simple terms, a partnership is when two or more people go into business together with a view to making a profit.

There are a few ways this can look in practice:

• General partnership: the most common form - usually governed by the Partnership Act 1908 and the terms you and your partner agree to.
• Limited partnership: a more formal structure under the Limited Partnerships Act 2008, often used where there are passive investors (limited partners) and active managers (general partners).

Many small businesses operate as general partnerships without realising it - for example, two friends start invoicing clients together, share a business bank account, and split profits. Even without paperwork, you may already have a partnership (and the legal obligations that come with it).

If you want a clear snapshot of how partnerships work, What Is A Partnership is a helpful starting point.

Do You Need To Register A Partnership?

A general partnership doesn’t have a “registration” process in the same way a company does. However, you still need to handle the practical setup properly, such as:

• IRD numbers and income tax responsibilities (including how you’ll allocate profits) (note: this is general information only and isn’t tax or accounting advice)
• GST registration (if you expect to exceed the registration threshold, or if you register voluntarily) (note: this is general information only and isn’t tax or accounting advice)
• business bank accounts and accounting systems
• contracts with customers and suppliers (in the partnership name, or individual names)

And most importantly: you’ll want a written agreement setting out how you’re actually going to run things.

Advantages Of A Partnership For Small Businesses

Let’s start with the positives. The main advantages of a partnership tend to be about simplicity, shared workload, and flexibility - especially in the early stages of a business.

1) It’s Relatively Simple And Low-Cost To Set Up

Compared to forming a company, a general partnership can be quicker and cheaper to start. There’s no Companies Office incorporation process, no company constitution (unless you’re also using a company), and usually less admin upfront.

This is one reason partnerships are common for:

• service businesses (consulting, marketing, design, trades)
• hospitality ventures (small cafes, catering teams)
• family-run businesses
• side hustles that turn into “real” businesses

2) You Can Combine Skills, Time, And Money

A partnership can be a practical way to bring together different strengths. For example:

• one partner manages sales and client relationships
• one partner delivers the technical work
• one partner funds equipment or initial stock

That shared contribution can make it easier to grow revenue early - and it can reduce pressure on you as an individual founder.

3) Decision-Making Can Be Faster (When You’re Aligned)

When partners are on the same page, a partnership can feel agile. You can make decisions quickly without needing formal board resolutions or shareholder processes (as you would in a company).

This can be a big advantage if your business needs to respond quickly to customer demand or changing costs.

4) Flexibility In How You Share Profits And Roles

A key benefit of partnerships is that you can agree on a structure that fits your reality - not just a 50/50 split because it sounds fair.

For example, you might agree that:

• profits are split 60/40 based on time contribution
• one partner is repaid capital first before profits are divided
• different profit splits apply depending on service line or project type

This is exactly where a properly drafted Partnership Agreement can make your life much easier later (especially if circumstances change).

5) Privacy And Control (Compared To Some Other Structures)

Partnerships generally have fewer public filing requirements than companies. For some small businesses, that “low visibility” approach feels more comfortable.

That said, privacy doesn’t reduce your legal obligations - you still need to comply with the laws that apply to your industry and the way you operate (for example, consumer law and privacy law if you’re dealing with customers and collecting personal information).

Disadvantages Of A Partnership (And Why They Matter Legally)

Now for the part many business owners only discover after something goes wrong. The disadvantages of a partnership usually come down to risk allocation - particularly personal liability and relationship breakdown.

1) You Can Be Personally Liable For The Business’s Debts

In a general partnership, partners typically have personal liability for partnership debts. In practice, this often means liability can be joint and several - so a creditor may be able to pursue one partner for all of the debt (and it’s then up to the partners to sort out contributions between themselves). That means if the partnership owes money (for example, unpaid supplier invoices, lease obligations, damages from a claim), your personal assets may be at risk - not just the business’s assets.

Importantly, this can apply even if:

• you didn’t personally cause the problem
• the other partner signed the contract
• you weren’t involved in the decision

This is often the biggest legal “trade-off” when weighing up the pros and cons of a partnership.

2) You Can Be Liable For Your Partner’s Actions

Under partnership law principles, each partner can often bind the partnership (and the other partners) when acting in the ordinary course of the partnership business. The position can be different if the other party is on notice of restrictions (or the action is outside the usual scope of what the partnership does).

Here’s a common scenario: your partner enters into a contract with a supplier, or commits the business to a long-term expense. If that decision is within the scope of the partnership business, it may affect you too - even if you disagree.

This risk is one reason it’s crucial to be clear about:

• who can sign contracts
• spending limits
• who approves hiring staff
• who can take on debt or finance

3) Disputes Can Be Messy Without A Written Agreement

Many partnerships begin with trust and good intentions - but problems usually arise when the business starts succeeding (or when it starts struggling).

If you don’t have clear written terms, you may end up relying on default rules under the Partnership Act 1908, which might not reflect what you assumed was “fair” or “reasonable”.

Typical dispute triggers include:

• one partner working significantly more hours than the other
• disagreement over reinvesting profits vs taking drawings
• different risk appetites (e.g. taking on debt, expanding, hiring)
• one partner wanting to exit, retire, or sell their share
• relationship breakdown (including family partnerships)

If you’re already facing this situation, the process of how to end a partnership (and what to consider legally) becomes very important, very quickly.

4) Raising Capital Can Be Harder

Most external investors prefer clear ownership structures, limited liability, and easy transferability of interests - which is often simpler through a company than a general partnership.

In a partnership, bringing in a new partner (or investor-like contributor) can create complications around:

• who controls decisions
• how profits are split
• what happens if someone exits
• who is liable for past and future debts

If your plan includes serious growth, investment, or scaling into multiple locations, it’s worth considering whether a company structure will better support that long-term plan.

5) Business Continuity Can Be Fragile

In many partnerships, the business is deeply tied to the individuals involved. If a partner leaves, becomes unwell, loses their licence, or passes away, the partnership may need to be restructured - and in some cases dissolved - unless you’ve planned for this in advance.

This is where “boring” legal planning becomes a business-saving move.

How Do You Reduce Partnership Risks Without Losing The Benefits?

You don’t need to avoid partnerships entirely. Plenty of New Zealand businesses operate successfully as partnerships - they just treat the legal setup as part of the business foundation, not an afterthought.

1) Put A Partnership Agreement In Place (Before You Need It)

A good partnership agreement is essentially your rulebook. It can cover the practical stuff you’ll otherwise argue about later, like:

• ownership and profit shares (and whether they change over time)
• roles and responsibilities (who does what, and how performance is measured)
• decision-making (unanimous vs majority decisions, reserved matters)
• banking and drawings (how money is taken out, spending limits)
• what happens if someone wants to leave (exit process and notice)
• buy-out provisions (valuation methods, payment terms)
• dispute resolution (steps before court - e.g. mediation)
• restraints and confidentiality (protecting clients, suppliers, IP, trade secrets)

In other words: it’s how you stay friends (and stay profitable) when the pressure is on.

2) Be Clear On Who Can Sign What

One of the most practical risk controls is having clear internal rules for contracts. You can set policies like:

• contracts over $X require both partners’ approval
• only one nominated partner can sign leases or finance agreements
• customer terms must be approved before being issued

If you’re entering supplier agreements, customer contracts, or service terms, it’s often worth getting a Contract Review so you’re not accidentally taking on obligations you can’t meet.

3) Treat Compliance As A Business Asset

Partnerships still need to comply with the laws that apply to their operations. Depending on your business, this can include:

• Fair Trading Act 1986 (advertising and promotions must not be misleading)
• Consumer Guarantees Act 1993 (product/service guarantees in many B2C situations)
• Health and Safety at Work Act 2015 (you must take reasonably practicable steps to keep people safe)
• Privacy Act 2020 (if you collect customer or employee personal information)

If you collect customer details online, run a mailing list, or store client records, having a clear Privacy Policy is a simple but important step to stay compliant and build trust.

4) Plan For “What If” Scenarios Early

It can feel pessimistic to plan for a breakup when you’re just starting out - but it’s one of the smartest things you can do.

Ask yourselves questions like:

• What if one partner wants to sell their share?
• What if one partner stops contributing time?
• What if the business needs cash and one partner can’t contribute?
• What if you get a big offer to buy the business?

When you agree on these rules upfront, you reduce the chance of disputes later (and you avoid relying on default legal rules that may not match your intentions).

Should You Consider A Company Instead Of A Partnership?

Sometimes the best way to manage the disadvantages of a partnership is to use a different structure - especially if you’re taking on higher risk, hiring staff, signing long-term leases, or planning to scale.

A common alternative is incorporating a company, which can provide limited liability (though there are still situations where directors can be personally liable, and banks often require personal guarantees).

If you’re thinking about that path, set up a company can be a cleaner foundation for growth.

What If You Want A “Partnership Feel” But With Company Protection?

Many founders run the business through a company, but still operate like business partners day-to-day. In that situation, your key governance document is usually a Shareholders Agreement, which covers similar issues to a partnership agreement (decision-making, exits, buy-outs, dispute resolution), but tailored for a company structure.

This can give you:

• more credibility with investors or lenders
• clear ownership units (shares)
• better continuity if someone exits
• more defined legal separation between business and personal assets (in many cases)

The “right” choice depends on your risk profile, industry, growth plans, and how you and your co-owner want to work together - so it’s worth getting tailored legal advice before committing.

Key Takeaways

• The main pros and cons of a partnership come down to flexibility and simplicity versus personal risk and potential disputes.
• A general partnership is often easy to start, but partners can face personal liability for debts and can also be affected by each other’s actions.
• Without a written agreement, you may be stuck with default rules under the Partnership Act 1908, which may not match what you intended.
• A well-drafted partnership agreement can clarify profit splits, decision-making, exit rules, dispute resolution, and who can sign contracts - protecting the business from day one.
• If you’re planning to scale, raise capital, or limit personal risk, a company structure (supported by a shareholders agreement) may be a better fit.
• Even simple partnerships still need to comply with key NZ laws, including consumer law, health and safety obligations, and privacy requirements where relevant.
