If you’re negotiating a contract and you see the words “cascading clause”, “tiered clause” or “waterfall clause”, it can feel like you’ve stepped into a different language.
Don’t stress - a cascading clause is simply a drafting technique lawyers use to manage uncertainty and reduce the risk of a clause failing altogether.
This (2026 updated) guide explains what a cascading clause is, why they’re used in New Zealand contracts, when they can help (and when they can backfire), plus the practical steps you should take before agreeing to one.
What Is A Cascading Clause?
A cascading clause (sometimes called a tiered clause or waterfall clause) is a contract clause that sets out multiple alternative versions of the same obligation, usually arranged from the most preferred option to the least preferred.
The idea is that if the “top” option can’t apply (for example, because it’s found to be unenforceable, too broad, or doesn’t match what happens in real life), the contract “falls down” to the next option - and so on.
In practice, a cascading clause can help you keep some legal protection even if the strongest version of the protection doesn’t hold up.
What Does A Cascading Clause Look Like?
You’ll often see cascading clauses used for things like:
- Restraint of trade / non-compete obligations (e.g. different time periods and geographic areas)
- Termination and notice periods (e.g. different notice requirements depending on role, tenure, or trigger event)
- Liability caps (e.g. a preferred cap, with lower fallback caps if the first is invalid)
- Dispute resolution steps (e.g. negotiation → mediation → arbitration → court)
- Pricing / payment mechanisms where different outcomes apply depending on a defined trigger
A classic example is a restraint clause that says (paraphrased):
- For 12 months in New Zealand; if that’s too wide, then
- For 9 months in the North Island; if that’s too wide, then
- For 6 months in Auckland.
The structure gives a decision-maker “options” without rewriting the contract later.
Why Do Businesses Use Cascading Clauses?
Cascading clauses are usually about risk management. In real business relationships, you often need to make a contract work even when:
- the parties can’t predict every future scenario;
- the law draws a line between what’s reasonable and unreasonable (especially with restraints);
- different parts of the deal carry different risk levels; or
- enforcement might be tested months (or years) after signing.
Instead of gambling on one clause that might be knocked out entirely, the parties “cascade” through alternatives so the agreement is more likely to remain effective.
Common Situations Where Cascading Clauses Help
Here are some practical situations where a cascading clause can be genuinely useful:
- Protecting goodwill when someone leaves: If your business relies on relationships and know-how, a cascading restraint can help protect you without overreaching.
- Managing a tricky negotiation: Sometimes the other party won’t agree unless they see your preferred position - but they also want reassurance there are fair fallbacks.
- Reducing the “all or nothing” risk: If one version fails, you may still have a workable backup.
- Making complex deals more operable: For example, a dispute process that escalates step-by-step can keep things moving instead of deadlocking.
It can also be helpful where you’re trying to keep your contract aligned with broader documents like a Company Constitution or a Shareholders Agreement, especially if ownership changes or a co-founder exits.
Where Do You Commonly See Cascading Clauses In NZ Contracts?
Cascading clauses aren’t limited to any one industry. In New Zealand, we often see them across employment, commercial contracts, and startup documentation.
Restraints Of Trade (Non-Competes And Non-Solicits)
This is one of the most common areas for cascading clauses.
Restraint clauses need to be reasonable to be enforceable. A clause that’s too broad (in time, geography, or restricted activity) risks being struck out or limited.
Cascading drafting is used to offer “narrower” options if the broadest option doesn’t stand.
In an employment context, this is often paired with a properly drafted Employment Contract (and potentially separate restraint documentation, depending on the scenario).
Liability And Risk Allocation
Liability clauses are another common area, especially when the parties are negotiating how much each side is “on the hook” for if something goes wrong.
A cascading clause might include:
- a primary liability cap (e.g. fees paid in the last 12 months);
- a secondary cap (e.g. a fixed dollar amount); and
- a final fallback (e.g. the minimum cap permitted by law).
These clauses often sit alongside indemnities, exclusions and warranties, and they need to be drafted carefully so they don’t contradict each other.
Dispute Resolution Processes
Many businesses prefer not to jump straight into court. A cascading dispute resolution clause can require parties to attempt:
- good faith negotiation;
- then mediation;
- then arbitration; and/or
- then court proceedings (as a last resort).
This can be particularly helpful where you want to preserve an ongoing relationship (like supplier arrangements, service agreements, or partnerships).
Termination And Exit Rights
Cascading clauses can also appear in termination rights - for example, different notice periods depending on the reason for termination, the contract stage, or severity of breach.
In some cases, rather than a cascading clause, parties use a more formal change document such as a Deed Of Variation to update terms once circumstances are clearer. Which approach is better depends on whether you want flexibility now, or certainty plus a controlled change process later.
Are Cascading Clauses Enforceable In New Zealand?
Cascading clauses can be enforceable in New Zealand, but they’re not a “magic fix”. Whether they work depends heavily on:
- how they’re drafted (clarity matters a lot);
- what type of clause it is (restraints are treated differently from, say, payment clauses);
- the context of the agreement (bargaining power, negotiation history, commercial purpose); and
- whether the cascading options are genuinely separable (so one option can stand on its own).
In other words, it’s not enough to stack alternatives and hope the law will “pick one”. The clause needs to be structured so it’s actually workable.
What Can Go Wrong With A Cascading Clause?
Cascading clauses can cause headaches when they’re drafted poorly. Common issues include:
- Uncertainty: If it’s unclear which tier applies, you can end up arguing about the meaning rather than solving the problem.
- Contradictions: The tiers might conflict with other parts of the contract (especially definitions, termination clauses, or IP clauses).
- Unfairness concerns: If a clause feels overly one-sided, it can raise enforceability issues and also damage the relationship.
- Operational confusion: Your team may not know what you’re actually allowed to do (or what you’re required to do) day-to-day.
A simple rule of thumb: a cascading clause should make the contract more certain in practice, not less.
How Courts And Tribunals Tend To Think About These Clauses
New Zealand decision-makers generally want contracts to be:
- clear (so people can understand their obligations);
- commercially sensible (so the clause fits the deal); and
- fair and reasonable where the law requires it (especially in restraints and employment contexts).
That’s why “copy and paste” tiered restraints can be risky - you want each tier to be defensible and tied to real business needs.
How Do You Draft A Cascading Clause Properly?
If you’re considering using a cascading clause (or you’ve been sent a contract containing one), the goal is to get the clause to do three things:
- Be clear about what the tiers are;
- Be triggered in a predictable way; and
- Stay consistent with the rest of the contract.
1) Start With The Commercial Risk You’re Trying To Manage
Before you write (or negotiate) tiers, ask: what are we actually trying to protect?
For example:
- If you’re protecting customer relationships, a non-solicitation might be more appropriate than a broad non-compete.
- If you’re worried about a contractor walking away mid-project, you might need staged termination rights and handover obligations.
- If you’re concerned about losses, you may need a realistic liability cap rather than an absolute exclusion.
When the purpose is clear, the tiers are easier to justify and easier to enforce.
2) Make Each Tier Stand Alone
Each tier should be drafted so that it can operate independently.
That means each option should be complete in itself, not reliant on a reader “mixing and matching” bits from different tiers.
For example, for a restraint, each tier should specify:
- the restricted activity (what you can’t do);
- the duration (how long); and
- the geographic scope (where).
3) Keep The Number Of Tiers Sensible
More tiers doesn’t always mean more protection.
If you create a clause with 15 combinations of time and geography, you risk making it unreadable, harder to administer, and more likely to be challenged for uncertainty.
Usually, a small number of well-chosen tiers is more effective than a giant matrix of options.
4) Align It With The Rest Of The Contract
Cascading clauses often interact with other contract terms, like:
- confidentiality and IP ownership;
- payment and invoicing (especially if a breach changes pricing);
- termination rights and consequences; and
- dispute resolution processes.
If you’re already using a broader agreement structure (like a master agreement with statements of work), it can be worth ensuring the tiers don’t conflict with the overall framework (for example, by documenting project-specific changes using a Master Services Agreement approach).
5) Don’t Use A Cascading Clause To “Sneak In” An Unreasonable Position
This is a big one.
If your top tier is obviously unreasonable (for example, “you can’t compete anywhere in NZ for 5 years”), a fallback tier won’t necessarily save it - and it can also undermine your credibility in negotiation.
A better approach is to choose tiers that reflect what you could genuinely justify if challenged.
What Should You Do Before You Agree To A Cascading Clause?
Cascading clauses can be helpful, but you shouldn’t treat them as boilerplate.
Before you sign, work through a quick reality check.
Check Which Side The Clause Benefits (And Whether That’s OK)
A cascading clause is often inserted to protect one party (usually the party with more to lose if things go wrong).
That’s not automatically a problem - but you should understand the trade-off you’re making.
Ask yourself:
- Does this clause restrict my ability to earn income or work elsewhere?
- Could this create obligations that are hard to comply with operationally?
- Is there a practical reason the other party needs this protection?
Make Sure The Clause Is Usable In Real Life
If the tiers are so complex that no one can work out what applies, the clause won’t help you when you need it most.
For example, in a dispute resolution cascade, check:
- timeframes for each step (so the other party can’t delay forever);
- who pays for mediation/arbitration; and
- where disputes must be heard (jurisdiction and venue).
Consider Whether A Different Document Would Be Cleaner
Sometimes, instead of a cascade, you might be better off with:
- a clear single clause plus a controlled amendment process;
- a side letter for a special scenario; or
- a separate deed for one-off obligations (depending on the situation).
If the contract is being signed as part of a wider transaction (like a business sale), it’s also worth checking how the clause interacts with your overall deal documents - including whether the agreement is truly unconditional or subject to conditions that could change the risk profile.
Get The Contract Reviewed Before You Sign
A cascading clause can look “standard” at first glance, but the detail matters. Small drafting choices can change the effect of the clause completely.
If you’re unsure, it’s worth getting help through a proper Contract Review so you know what you’re agreeing to and what you can negotiate.
Key Takeaways
- A cascading clause is a tiered clause that sets out multiple alternative versions of an obligation, so if the top option can’t apply, the contract can fall back to the next option.
- Cascading clauses are commonly used for restraints of trade, liability caps, termination rights, and dispute resolution processes.
- They can be enforceable in New Zealand, but only if they’re drafted clearly and each tier can operate as a complete, workable option.
- Poorly drafted cascading clauses can create uncertainty, contradictions, and real operational confusion - which can increase disputes rather than prevent them.
- The best cascading clauses are tied to a clear commercial purpose, have a sensible number of tiers, and fit cleanly with the rest of the agreement.
- If you’re presented with a cascading clause (or you want to use one), getting tailored legal advice early can save you major headaches later.
