Frustration Of Contract In New Zealand: What It Means For Agreements

If you run a small business, you've probably had a moment where a deal that looked straightforward suddenly becomes impossible to carry out. A supplier can't deliver, a venue shuts down, a key event is cancelled, or a new legal restriction changes what you can do.

When something big and unexpected happens after a contract is signed, you might wonder: "Do we still have to perform this agreement?"

In New Zealand, the idea of contract frustration (often called "frustration of contract") can sometimes apply in these situations. It's not a "get out of contract free" card, but it may be relevant where an agreement genuinely can't be performed due to events outside the parties? control.

Below, we break down what frustration of contract means, when it can apply, what happens if a contract is frustrated, and (most importantly) how you can reduce the risk of being caught out in future agreements.

What Is Frustration Of Contract?

Frustration of contract is a legal principle that can apply when, after a contract is formed, an unexpected event occurs (through no fault of either party) that makes the contract:

• impossible to perform, or
• radically different from what the parties originally agreed.

When a contract is "frustrated", the general idea is that the parties are discharged from further performance from the point of frustration. In other words, you're usually not required to keep doing the parts of the contract that haven't been performed yet.

This concept exists to deal with situations where it would be unfair (or unrealistic) to insist on strict performance because the underlying assumptions behind the deal have collapsed.

Why This Matters For Small Businesses

For small businesses, frustration of contract often comes up in real-world agreements like:

• supplier and manufacturing arrangements
• service contracts and project work
• venue hire and events
• commercial arrangements where a key input becomes unavailable
• some commercial lease scenarios (depending on the facts and the lease wording)

It's also closely connected to how your contracts are drafted in the first place. If your contract already deals with certain "unexpected events" (for example via a force majeure clause), frustration might be less likely to apply because the contract has already allocated that risk.

Frustration Is Different From "Just Being Unhappy With The Deal"

It's worth saying upfront: frustration is not about one party regretting the bargain, running out of cash, or finding the deal inconvenient.

Commercial hardship on its own is usually not enough. The event typically needs to be genuinely outside the parties? control and serious enough that the contract can't sensibly continue.

Also, frustration is different from situations where:

• one party has breached the agreement (that's a breach/termination issue)
• the contract was entered into based on wrong information or misleading conduct (that may raise misrepresentation or Fair Trading Act issues)
• the contract is poorly drafted or incomplete (that's a contract drafting problem, not frustration)

Before you get into frustration arguments, it helps to check whether you have a solid, enforceable contract in the first place. If you're ever unsure, it's useful to understand what makes a contract legally binding so you're not trying to rely on legal principles when the real issue is the contract fundamentals.

When Can A Contract Be Frustrated In NZ?

Whether frustration of contract applies depends heavily on the facts. There isn't one "magic checklist", but there are common themes courts look at.

In practical terms, frustration is more likely where:

• the event occurred after the contract was formed
• the event was not caused by either party
• the event was not something the parties reasonably contemplated (or allocated risk for) when signing
• the event makes performance impossible or fundamentally different, not just more expensive or difficult

Examples Of Events That Can Lead To Frustration

Every situation is different, but examples that can be relevant include:

• Illegality / change in law: a new law or government order makes the contracted activity unlawful
• Destruction of something essential: the subject matter of the contract is destroyed (e.g. a specific venue burns down before a booked event)
• Non-occurrence of a key event: where the contract is built around an event or circumstance that fails to occur (and that circumstance was central to the deal)
• Extreme interruptions: a significant interruption that defeats the purpose of the contract, not merely delays it

That said, not every "major disruption" frustrates a contract. For instance, if an alternative method of performance exists (even if inconvenient), frustration might not apply.

What About COVID-Style Disruptions?

Large-scale disruptions (like pandemics, natural disasters, or major supply chain breakdowns) can raise frustration arguments, but the outcome depends on:

• what the contract actually says (especially any force majeure, delay, suspension, and termination rights)
• what the parties assumed when contracting
• whether performance is truly impossible, or just harder
• how long the disruption lasts compared to the contract term

This is why "boilerplate" contracts can be risky. Two businesses might face the same external event, but have completely different outcomes depending on the wording of their agreement.

Frustration Versus Force Majeure

Small business owners often mix these up, so here's the simple distinction:

• Force majeure is a contract clause (it only applies if your contract includes it, and it applies according to its wording).
• Frustration is a legal doctrine that can apply even if your contract is silent on unexpected events.

If your contract has a force majeure clause that covers the event, you'll usually follow the process in that clause (e.g. notice requirements, suspension periods, termination triggers).

If the contract doesn't deal with the event (or the clause doesn't cover it), you might explore whether the contract is frustrated - but it's a higher threshold than many people expect.

What Happens If A Contract Is Frustrated?

If a contract is frustrated, the main practical effect is that both parties are typically released from their future obligations from the date of frustration.

However, that doesn't automatically answer the money question (and for small businesses, that's usually the biggest issue):

• Do you have to refund payments already made?
• Can you recover costs you've already incurred?
• What happens to deposits, part-payments, or progress payments?

The Court Can Make Orders About Money And Benefits

In New Zealand, legislation (now contained in the Contract and Commercial Law Act 2017, which picked up the old "frustrated contracts" framework) gives courts power, in some cases, to make orders about money paid and benefits transferred before the frustrating event.

In plain terms, the court may consider things like:

• money paid (or payable) before frustration
• expenses incurred by a party in performing the contract
• whether one party has received a valuable benefit (even if the full contract wasn't completed)

The goal is generally to reach a fair outcome on the facts, but the result isn't automatic and will depend on the circumstances (and any relevant contract terms).

This is one reason frustration disputes can become expensive: even if everyone agrees the contract can't continue, the parties may still fight about what a fair financial adjustment should look like.

Frustration Doesn't Always Mean "No One Is Liable"

Frustration generally applies where neither party is at fault for the event. But disputes often happen because one party says:

• the event wasn't truly outside the other party's control (e.g. they failed to take reasonable steps to avoid or mitigate it), or
• the contract could still be performed (just differently), or
• the contract already allocated the risk (so frustration shouldn't apply)

If you're in a disagreement, it's crucial to avoid acting too early - for example, walking away from the contract without following a proper legal process can create a separate breach issue.

Where you're considering ending an agreement, the safest approach is usually to get advice on terminating a contract based on your specific facts and the wording of your agreement.

How Do You Know If Frustration Applies To Your Agreement?

If you're dealing with a disrupted deal right now, here's a practical way to think about it (without getting lost in legal jargon).

Step 1: Identify The "Core Purpose" Of The Contract

Ask: what is the contract really about?

For example:

• A venue hire agreement might be about providing access to that specific venue on that specific date.
• A supply agreement might be about delivering specific goods meeting specific standards within a defined timeframe.
• A service contract might be about delivering a project outcome by a critical deadline (like a launch date).

Frustration is more likely where the event destroys the contract's core purpose, not just a side detail.

Step 2: Check The Contract Wording First

Before relying on frustration, review your agreement for clauses about:

• force majeure / events outside control
• delays and extensions of time
• suspension rights
• termination rights and notice requirements
• refunds, deposits, and limitation of liability

If the contract already deals with the situation, the contract terms will often guide what happens next.

If you don't have a clear agreement (or it's a patchwork of emails and quotes), you might want to tighten your contracting process going forward. Even a quick Contract Review can help you understand what your current contract actually does (and doesn't) protect you from.

Step 3: Look At Whether Performance Is Impossible Or Just Hard

A good "business owner" test is:

• If you had unlimited money, could you still perform the contract lawfully and realistically?

If the answer is "yes, but it would be painfully expensive," that leans away from frustration.

If the answer is "no, we literally can't do it (or it would be a completely different deal)," frustration may be worth exploring.

Step 4: Act Carefully (And Document Everything)

If you think frustration might apply, avoid jumping straight into aggressive emails or refusing performance without a plan.

Instead, consider:

• sending a without prejudice proposal to renegotiate
• requesting evidence of the event's impact (where relevant)
• exploring a mutually agreed variation (often faster and cheaper than fighting)
• getting advice before you issue a notice of termination or cancellation

Many businesses resolve "frustration-style" situations commercially by documenting a revised outcome. That can be done via a simple contract update, or sometimes a Deed of Variation where you want more certainty and formality about the change.

How Can You Reduce Frustration Risk In Future Business Contracts?

You can't prevent unexpected events from happening, but you can prevent a lot of contract disputes by putting the right legal foundations in place from day one.

Here are practical drafting and process tips that reduce the risk of having to rely on frustration of contract later.

1) Use A Clear Force Majeure Clause (Tailored To Your Business)

A good force majeure clause should be tailored to how your business actually operates. It may cover things like:

• natural disasters and extreme weather
• pandemics and public health orders
• government restrictions, export/import blocks, or border closures
• supply chain breakdowns (where appropriate)
• industrial action

It should also set out the process: notice, mitigation obligations, suspension periods, and when termination is allowed.

Without this, you may end up arguing about frustration of contract, which can be slower, riskier, and harder to predict.

2) Build In "Plan B" Performance Options

If your contract allows alternative performance, frustration becomes less likely (because the contract has a built-in workaround).

Depending on your industry, that might include:

• substitution rights (e.g. equivalent goods if a specific product is unavailable)
• delivery flexibility (e.g. multiple delivery windows)
• remote delivery options for services
• split deliveries or milestone-based completion

The key is to keep these options clear so they don't create new disputes.

3) Be Specific About Deposits, Prepayments, And Cancellation

Deposits and upfront payments are where disputes often get personal fast - especially for small businesses with tight cash flow.

Your contract should clearly set out:

• whether a deposit is refundable and under what circumstances
• how cancellation fees work
• what happens if work has started (for services)
• how you calculate costs already incurred

This doesn't just reduce litigation risk - it also makes your customer/supplier relationships more straightforward.

4) Put Your Changes In Writing (Don't Rely On "We Agreed Over The Phone")

When circumstances change, many businesses do the sensible thing and renegotiate. The problem is that the renegotiation often isn't properly documented.

If you change key terms (scope, timing, price, deliverables), document it properly. Depending on what you're changing, this could be:

• a written variation clause process in the contract
• a formal deed (where you want stronger enforceability)

If you're ever unsure about whether you should be using a deed or a standard agreement, understanding the difference between deed and agreement can help you choose the right format for the situation.

5) Include A Practical Dispute Resolution Process

If things go sideways, you want a path to resolution that doesn't burn months (and thousands of dollars) before anyone even sits down to negotiate.

Many small business contracts include a staged process like:

• good faith negotiation between business owners/managers
• mediation
• then court action (as a last resort)

This won't prevent every dispute, but it can stop a stressful situation from becoming unmanageable.

6) Make Sure Your Contract Setup Is Solid From The Start

Frustration disputes often reveal a deeper issue: the business never had a properly drafted contract in the first place.

For example, you might have:

• unclear deliverables ("we'll do our best" style wording)
• missing timelines
• no clear termination rights
• no allocation of risk for external events

Putting proper agreements in place early can save you a lot of cost and stress later - and it usually makes your business look more professional too.

Key Takeaways

• Frustration of contract can apply in New Zealand when an unforeseen event (not caused by either party) makes performance impossible or fundamentally different from what was agreed.
• Frustration is not the same as a contract becoming inconvenient, unprofitable, or harder to perform - commercial hardship alone usually isn't enough.
• If a contract is frustrated, parties are generally discharged from future obligations, but the financial outcome (refunds, expenses, benefits received) can still be disputed and, in some cases, may be adjusted by a court under the Contract and Commercial Law Act 2017.
• Before relying on frustration, you should check the contract wording for force majeure, delay, and termination clauses, and be careful not to create a separate breach by acting too quickly.
• You can reduce frustration-related disputes by drafting contracts with clear force majeure clauses, practical variation processes, cancellation/refund terms, and dispute resolution steps.
• If you're not sure whether frustration applies, it's worth getting tailored advice - the answer often depends on the specific contract and the exact event.
