How to Protect Your Business Contracts Against Unforeseen Circumstances

Unexpected events can turn a sensible deal into a costly problem very quickly. A supplier may stop delivering, freight costs may spike, a key venue may close, or a government restriction may delay performance. Many New Zealand businesses only discover the gaps in their contracts when something has already gone wrong.

The most common mistakes are relying on a short template that says nothing about disruptions, assuming a force majeure clause covers every kind of delay, and accepting a provider's standard terms without checking who carries the risk. Another common issue is relying on verbal assurances instead of making the written terms spell out what happens if circumstances change.

The good news is that you can reduce a lot of this risk before you sign. The right contract wording will not eliminate every commercial problem, but it can give your business clearer options, stronger leverage and a better chance of limiting losses. This guide explains how to protect your business contracts against unforeseen circumstances for businesses in New Zealand, what clauses matter most, and where founders often get caught out.

Overview

Protecting a contract against unforeseen circumstances means allocating risk before something goes wrong. Your contract should say what counts as an unexpected event, who must notify whom, whether obligations pause or continue, when prices can change, and how either side can exit if performance becomes impossible or commercially unworkable.

For New Zealand businesses, the practical aim is not to predict every disruption. It is to make sure the agreement gives you a workable process when delays, shortages, shutdowns or legal changes affect performance.

  • Define the events that trigger relief, such as natural disasters, supply chain disruption, strikes, utility outages, pandemics or changes in law
  • Check whether the affected party is excused from performance, delayed only, or still required to find alternatives
  • Set notice rules, evidence requirements and timelines for updating the other party
  • Deal with pricing changes, minimum orders, substitutes and partial performance
  • State when either party can suspend, renegotiate or terminate the contract
  • Match the contract terms to insurance, lease obligations, financing commitments and other linked agreements
  • Make sure the risk allocation in standard terms reflects the reality of your business operations

What To Know Before You Start

For a New Zealand business, protecting a contract against unforeseen circumstances means deciding in advance who carries the risk of disruption and what happens next. If the contract is silent, the outcome may depend on general legal principles that are narrower and less flexible than most business owners expect.

In practice, this issue comes up in supply agreements, service agreements, logistics arrangements, manufacturing terms, event bookings, software subscriptions, commercial leases and contractor arrangements. It also matters when you are the customer, not just when you are supplying goods or services.

Why standard contracts often fall short

Many standard terms are written to protect the party who drafted them. They may include a force majeure clause, but the wording is often tight, one-sided, or vague about what relief is actually available.

For example, a clause may excuse a supplier from delay but still require you to keep minimum spend commitments. Another may let a provider suspend services without giving you any termination right. This is where founders often get caught, especially before they accept the provider's standard terms.

Force majeure is only part of the answer

A force majeure clause is a contractual mechanism that deals with certain events outside a party's control. New Zealand law does not automatically insert a broad force majeure right into every contract. If you want one, it generally needs to be written into the agreement.

The wording matters. Some clauses only cover extreme events such as earthquakes or war. Others extend to labour shortages, transport failures, cyber incidents, public health restrictions, or changes in law. A clause that is too narrow may not help when the problem you face is commercially serious but not listed in the contract.

You also need to check what the clause actually does. It may:

  • pause performance for a limited period
  • remove liability for delay but not for payment obligations
  • require the affected party to mitigate the impact
  • allow termination after a long disruption period
  • exclude relief where the event could have been avoided or overcome

Frustration is not a reliable fallback

Some business owners assume that if an event makes the contract difficult, the law will simply cancel it. That is not usually how it works. The legal doctrine of frustration can apply where an unforeseen event makes performance impossible or radically different from what the parties agreed, but the threshold is high.

Higher costs, reduced profit, staff shortages or inconvenience may not be enough. If you rely on frustration instead of clear contract drafting, you may end up in a much weaker position than you expected.

Unforeseen circumstances are broader than disasters

The main risk is not limited to dramatic events. Plenty of contract failures start with more ordinary business problems.

Examples include:

  • a key imported component becomes unavailable
  • a subcontractor stops operating
  • shipping delays make delivery dates unrealistic
  • a venue or premises becomes inaccessible
  • a software provider changes features critical to your operations
  • new compliance requirements increase the cost of performance
  • a sharp increase in raw material prices makes the original pricing unsustainable

Good contracts address these situations directly rather than treating all disruption as a legal afterthought.

Before you sign a contract, check whether it gives your business a practical path through disruption, not just a theoretical legal clause. The best protection usually comes from a combination of force majeure wording, change mechanisms, termination rights and clear operational obligations.

1. Define the trigger events clearly

A clause is only useful if you can tell when it applies. Vague references to events beyond reasonable control can lead to arguments. A better approach is to use a general definition plus examples that suit your industry and supply chain.

Depending on the contract, the list may include:

  • natural disasters and extreme weather
  • earthquakes, floods and fires
  • pandemics and public health measures
  • strikes, lockouts and labour shortages
  • transport, freight or port disruption
  • internet, hosting or utility outages
  • government action, regulatory change or changes in law
  • acts or omissions of critical third party suppliers

Think carefully about exclusions too. If the event is really a pricing risk, the other side may resist calling it force majeure. In that case, a separate price review or hardship clause may be more effective.

2. Decide what happens to performance obligations

Your contract should say whether obligations are suspended, reduced, delayed, or replaced with alternative performance. If you leave this unclear, the parties may disagree about whether work must continue in a modified form.

Key points to address include:

  • whether deadlines extend automatically or only by agreement
  • whether partial performance is allowed
  • whether substitute goods, materials or services are acceptable
  • whether payment obligations continue during the disruption
  • whether service levels are reduced temporarily

This matters most where your own customer obligations depend on someone else performing first. A mismatch between linked contracts can expose your business to claims even if your supplier is excused.

3. Include notice and evidence requirements

If an unexpected event occurs, the contract should tell the affected party exactly what to do. A good clause requires prompt written notice, a description of the event, the expected impact, and regular updates.

Without this, you may only hear about a major problem after deadlines have already been missed. Notice provisions also help test whether the event is genuine or whether poor planning is being dressed up as an external disruption.

4. Require mitigation, not passivity

The affected party should usually be required to take reasonable steps to avoid or reduce the impact. That may include sourcing alternatives, reallocating labour, using substitute routes, or adopting temporary workarounds.

If mitigation is not addressed, one party may have little incentive to solve the problem quickly. In service agreements, this can be especially important where a provider has multiple clients and may prioritise whichever contracts are most favourable to them.

5. Deal with price changes and commercial hardship

Not every unforeseen circumstance makes performance impossible. Sometimes the real issue is that the original price no longer makes commercial sense. If the contract does not address this, a supplier may still be legally bound to perform at a loss, or may simply breach and force a dispute.

Consider whether the contract should include:

  • a price adjustment mechanism tied to objective inputs
  • a right to renegotiate after defined cost increases
  • a process for reducing scope if costs change materially
  • a right to terminate if renegotiation fails

This area needs careful drafting. Clauses that simply say the parties will negotiate in good faith can be too uncertain if they do not explain what happens when no agreement is reached.

6. Check termination and exit rights

If disruption continues, there needs to be an endpoint. A well-drafted contract says when either party can walk away and what happens to work in progress, deposits, prepaid amounts, confidential information and returned property.

Before you sign, look for:

  • the length of disruption required before termination is allowed
  • whether termination is available to both parties or only one
  • refund rules and payment for partially completed work
  • transition assistance if services need to move elsewhere
  • survival clauses for confidentiality, liability caps and payment obligations

7. Review liability caps and indemnities with the disruption clauses

A force majeure or hardship clause can lose much of its value if the liability section cuts across it. You need to read the contract as a whole.

For example, a supplier may be excused from delay but still indemnify the customer for losses caused by that delay. Or your liability cap may exclude indirect loss but leave direct replacement costs uncapped. The answer is not always to push for the lowest possible liability, but to make sure the clauses are internally consistent.

Your main contract should fit with your insurance cover and other commitments. If your lease, finance documents, customer contracts and supplier agreements all allocate disruption risk differently, a single unexpected event can create a chain of exposure.

Before you spend money on setup or commit to fixed delivery dates, compare the key risk points across your documents. This is especially relevant for businesses with imported goods, outsourced services, event dependencies or major equipment commitments.

9. Record key assumptions in writing

If the deal depends on a particular supplier, timing window, regulatory position, site access arrangement or technical environment, put that into the contract. Hidden assumptions are a common source of disputes.

Before you rely on a verbal promise, ask whether the contract should expressly state:

  • critical dependencies
  • required approvals or third party inputs
  • delivery windows that matter commercially
  • minimum stock, staffing or system requirements
  • who bears the consequences if those assumptions fail

Common Mistakes With How to Protect Your Business Contracts Against Unforeseen Circumstances

The biggest mistakes usually happen before the problem starts. Businesses often accept vague drafting, skip negotiation on practical risk points, and assume a general clause will solve a very specific operational issue.

Treating force majeure as a magic solution

A short clause that says neither party is liable for matters beyond their control can sound helpful, but it may not answer the questions that actually matter. Does the event have to make performance impossible, or just harder? Does the affected party need to mitigate? Can the other party terminate? Do payment obligations continue?

If those questions are not answered, the clause may create more debate than protection.

Failing to define supply chain dependencies

Many SMEs depend on one manufacturer, importer, courier network or software provider. If your contract promises fixed delivery or service outcomes without recognising those dependencies, your business may wear the risk even though the disruption started elsewhere.

This often appears in wholesale, ecommerce, events, construction-adjacent services and specialist consulting arrangements.

Accepting one-sided standard terms

Standard terms often let the drafting party suspend, vary pricing or terminate on broad grounds, while giving the other side very limited rights. That imbalance is easy to miss when everyone is focused on price and timing.

Before you sign, read the clauses on delay, variation, suspension, termination, and liability together. The risk is usually in the interaction between them.

Ignoring notice requirements

Some contracts require notice within a very short timeframe for relief to apply. If your team misses that step, your business may lose the benefit of the clause entirely.

This is not just a legal drafting issue. It is also an internal process issue. Someone in the business needs to know what to do when a disruption appears.

Leaving price pressure out of the contract

Commercial reality changes. Freight, labour, currency exposure and material costs can shift sharply. If the contract is fixed price and long term, but has no review mechanism, the parties may end up in dispute even though the relationship was workable at the start.

Where cost volatility is a genuine risk, address it openly. It is usually easier to negotiate a fair review process before signing than after margins collapse.

Assuming email promises override the signed contract

If the written agreement says it is the entire agreement between the parties, side conversations and informal assurances may not carry the weight you expect. Founders often rely on commercial understanding that never makes it into the final document.

If a point matters during disruption, make sure the contract says it clearly.

Forgetting the customer-facing impact

If your supplier contract gives limited protection, your business may still have obligations to your own customers under your sales terms and under consumer and fair trading laws where they apply. A delay upstream does not automatically remove downstream responsibility.

This does not mean you can contract out of every risk. It means your internal supply contracts and external customer commitments should be consistent and realistic.

FAQs

Is a force majeure clause automatically included in New Zealand contracts?

No. A force majeure right usually needs to be written into the contract. If the agreement does not include one, you may need to rely on other legal arguments, which can be much narrower.

Can a business end a contract just because costs have gone up?

Not usually, unless the contract allows for price review, renegotiation or termination in those circumstances. Cost increases alone do not automatically end a contract.

What should a contract say about unforeseen circumstances?

It should define the triggering events, require prompt notice, explain whether obligations are suspended or modified, require mitigation, and set out termination and payment consequences if the disruption continues.

Do standard supplier terms usually protect both parties fairly?

Often no. Standard terms are commonly written in favour of the party providing them. Before you accept the provider's standard terms, check delay clauses, liability caps, termination rights and any broad discretion to vary pricing or services.

What if the contract depends on another supplier or landlord?

The dependency should be stated clearly in the agreement. If performance relies on a third party, your contract should explain what happens if that third party fails, delays or withholds access or landlord consent.

Key Takeaways

  • Protecting your contracts against unforeseen circumstances starts with clear risk allocation before you sign, not after a disruption occurs.
  • A force majeure clause can help, but only if it clearly defines the events covered and the consequences for performance, payment, mitigation and termination.
  • General legal doctrines such as frustration are not a reliable substitute for careful drafting and usually apply only in limited situations.
  • Price review mechanisms, hardship clauses, notice requirements and linked-contract checks are often just as important as the force majeure wording itself.
  • Founders commonly get caught by one-sided standard terms, hidden supply chain dependencies and verbal promises that never make it into the contract.
  • Your contract should match your operational reality, including third party suppliers, insurance, customer commitments and any critical assumptions the deal depends on.
