If you run a company in New Zealand, there’ll come a point where a “normal” shareholder vote isn’t enough.
Some decisions are considered so important (and potentially so risky) that the law expects a higher level of shareholder agreement. That’s where a special resolution comes in.
In this guide, we’ll break down what a shareholders special resolution is, when you’re likely to need one, and the practical steps to pass it properly. We’ll also cover common mistakes we see small businesses make (often without realising) and how to avoid headaches later.
This article is general information only and isn’t legal advice. Because the rules can depend on your constitution, shareholders agreement and the Companies Act 1993, it’s worth getting advice on your specific circumstances.
What Is A Shareholders Special Resolution?
A shareholders special resolution is a formal decision made by a company’s shareholders that requires a higher approval threshold than an ordinary resolution.
Under the Companies Act 1993, a resolution is generally treated as “special” if it is approved by at least 75% of the votes of those shareholders entitled to vote and voting on the resolution (including at a meeting). If the special resolution is passed by written resolution, the Act generally requires approval from shareholders holding at least 75% of the votes of shareholders entitled to vote (subject to any different threshold in the company’s constitution, where permitted).
That 75% threshold is a big deal. It’s designed to ensure major company changes can’t be pushed through by a simple majority without broad shareholder support.
Special Resolution Vs Ordinary Resolution (In Plain English)
- Ordinary resolution: usually passes with a simple majority (more than 50%). This is used for day-to-day company decisions.
- Special resolution: needs a higher level of agreement (typically 75%), because it’s used for major changes that could affect shareholder rights, company structure, or risk profile.
If you’re a founder, director, or shareholder trying to keep the company compliant and investor-ready, it helps to treat special resolutions as part of your “legal foundations” from day one, not as paperwork you scramble to assemble later.
Do You Always Need A Meeting?
Not always. A special resolution can be passed at a shareholder meeting, or by a written resolution signed/approved by shareholders (depending on your company’s rules and what the Companies Act allows for your situation).
Either way, what matters is that the resolution is properly drafted, the correct approval threshold is met, and the company records are updated.
When Do You Need A Shareholders Special Resolution?
For small businesses, the most common times a shareholders special resolution comes up are when you’re changing the “shape” of the company, changing shareholder rights, or doing something that significantly changes risk.
Here are some typical examples.
1. Changing The Company Constitution
If your company has a constitution, changes to it will usually require a special resolution. This is common when:
- you bring on investors and need to update governance rules
- you want to add or change share transfer restrictions
- you need to create or adjust share classes and rights
- you’re tightening decision-making rules as the business grows
In practice, a constitution often works alongside (and should align with) your Company Constitution and your Shareholders Agreement, so you don’t end up with internal documents pulling in different directions.
2. Major Transactions Or Structural Changes
Not every “major transaction” requires a special resolution under the Companies Act by default. However, special resolution requirements often arise through:
- specific Companies Act pathways (for example, certain amalgamations or arrangements)
- your company’s constitution
- your shareholders agreement (for example, “reserved matters” that require a special resolution or supermajority)
In practice, this can include things like:
- approving a major asset sale or business sale pathway (where your constitution/SH agreement requires it)
- entering into arrangements that effectively change control of the company (where approval thresholds apply under your documents)
- approving certain restructures or reorganisations
If you’re planning a sale, investment round, or restructure, it’s worth getting your corporate documents checked early. It’s much easier to fix governance issues before the transaction is in motion.
3. Changing Shareholder Rights Or Share Structure
If you’re changing the rights attached to shares (for example, voting rights, dividend rights, or rights on liquidation), you may need a special resolution and, in some cases, additional approvals from the affected class of shareholders.
This often comes up when you:
- issue new share classes (e.g. preference shares)
- convert shares from one class to another
- vary rights attached to an existing class
Founders sometimes assume they can “just update the cap table” and move on. But if the paperwork isn’t done correctly, you can end up with disputes later about who owns what and what rights they actually have.
4. Share Buybacks
Depending on how the buyback is structured, share buybacks can trigger special resolution requirements and other compliance steps (including solvency requirements).
Because buybacks can materially affect remaining shareholders and company capital, they’re one of those areas where doing it “properly” really matters.
5. Any Time Your Constitution Or Shareholders Agreement Requires It
Even if the Companies Act doesn’t strictly require a special resolution for a specific decision, your company constitution or shareholders agreement might.
This is why document consistency matters. If your shareholders expect special approval for key decisions (like issuing new shares, taking on major debt, or appointing directors), that should be clearly reflected in your company documents and followed in practice.
How Do You Pass A Shareholders Special Resolution In NZ?
Passing a shareholders special resolution is usually straightforward, but there are a few critical steps you shouldn’t skip.
Here’s the typical process.
Step 1: Check The Companies Act And Your Company’s Internal Documents
Start by confirming:
- whether the decision legally requires a special resolution (or whether an ordinary resolution is enough)
- what your constitution says about notice, voting thresholds, and procedure
- whether your shareholders agreement adds any extra approval requirements
It’s common for small businesses to rely on informal practices early on (“everyone’s on board, so let’s just do it”). That works until there’s a disagreement, a new investor, or a due diligence process.
Step 2: Draft The Resolution Clearly (And Specifically)
A special resolution should be written so that a shareholder can understand exactly what they are approving.
It should usually include:
- the full company name
- the wording of the resolution (what is being approved)
- that it is intended to be a special resolution
- the date and method of passing (meeting or written resolution)
If the resolution is authorising a document (like an amended constitution, or an agreement), it’s often best practice to attach it or clearly identify the approved version. Vague resolutions can lead to arguments about what was actually approved.
Step 3: Decide Whether You’ll Use A Meeting Or A Written Resolution
There are two common pathways:
- Meeting: you call a shareholders meeting, give proper notice, and take votes.
- Written resolution: shareholders sign/approve a written document approving the special resolution (often easier for closely held companies).
Which one is best depends on your shareholder base, your timelines, and what your constitution allows. If you have multiple shareholders in different locations, a written resolution can be efficient. If the decision is contentious, a meeting may be better to ensure procedure and discussion are properly handled.
Step 4: Meet The Approval Threshold (Usually 75%)
This is the heart of it: the special resolution must receive the required level of support.
In most cases, that means at least 75% of votes of those shareholders entitled to vote and who actually vote on the resolution at a meeting. For written resolutions, the threshold is generally measured by the votes of shareholders entitled to vote who sign/approve the resolution (rather than “votes cast” at a meeting), subject to your constitution.
If your company has different share classes or special voting rights, the calculation can get more complicated. This is also where companies can accidentally get it wrong, especially if they’ve issued shares informally or haven’t updated their share records properly.
Step 5: Record It Properly (This Step Is Not Optional)
Once the resolution is passed, the company should:
- keep the signed resolution (or meeting minutes) with the company records
- update any registers affected (e.g. share register, director records, constitution records)
- make any required filings or notifications (where applicable)
Think of this as the “proof” you’ll need later. It’s often essential during investor due diligence, bank finance applications, audits, or a business sale.
Where the decision also needs director approval or board steps, you may also need supporting corporate records such as a Directors Resolution.
Common Mistakes Small Businesses Make With Special Resolutions
Most companies don’t get into trouble because they intended to do the wrong thing. They get into trouble because they didn’t realise the decision they made needed a different process.
Here are some common mistakes we see with shareholders special resolutions.
Using The Wrong Resolution Type
If a matter requires a special resolution and you pass an ordinary resolution instead, the decision can be vulnerable to challenge.
Even if all shareholders were “basically fine with it” at the time, problems can arise later if relationships change or new shareholders come in.
Not Following Notice Or Procedure Requirements
If you’re holding a meeting, you usually need to follow notice rules (timeframes, how notice is given, what information must be included).
If you don’t follow the correct procedure, you risk the resolution being invalid or disputed.
Informal Approvals That Aren’t Recorded
It’s very common for founders to approve things by email or in a quick conversation. The issue is that “everyone agreed” is hard to prove later if the company records aren’t clear.
This becomes a big issue when you:
- raise capital
- bring on a co-founder
- try to sell the business
- enter a dispute with a shareholder
Clean corporate records aren’t just “legal admin” - they’re part of what makes a company investable and sale-ready.
Company Documents Don’t Match Reality
If your share register, constitution, and shareholders agreement aren’t aligned with how the business actually operates, passing a special resolution can become messy.
This can happen when businesses grow quickly, issue shares informally, or use generic templates that don’t reflect the real deal.
It’s often worth getting the documents reviewed and updated so they work together as a practical set, not just “paperwork you have somewhere”.
How Special Resolutions Fit Into Your Wider Company Governance
A shareholders special resolution is one part of running your company properly. The real goal is having a governance setup that supports your business as it grows, including:
- clear rules about decision-making and control
- clear rights and obligations between shareholders
- records that match what has actually happened in the company
- well-drafted agreements for key events (investment, exits, disputes)
Shareholders Agreement Vs Constitution: Why Both Matter
In many small businesses, the Shareholders Agreement covers the “relationship rules” (what happens if someone wants to leave, how decisions are made, dispute resolution, drag/tag rights, etc.).
The Company Constitution is the public-facing rulebook for how the company is governed under the Companies Act framework.
If you’re making changes that require a special resolution, it’s a good prompt to check whether your documents still reflect your business, especially if you’ve recently brought on new shareholders, raised funding, or changed how the company operates.
What If Shareholders Don’t Agree?
If you can’t reach the required threshold, the special resolution won’t pass.
That doesn’t automatically mean the business is stuck, but it does mean you’ll need to consider options such as:
- negotiating a revised proposal that the required majority can support
- checking whether an alternative structure exists that doesn’t require a special resolution (without trying to “work around” shareholder rights)
- reviewing any deadlock or dispute provisions in your shareholders agreement
If a disagreement is brewing, getting legal advice early often saves a lot of cost (and stress) compared to trying to fix things after positions have hardened.
Do You Need To Notify The Companies Office?
Sometimes, yes - but it depends on what the special resolution is for.
Some changes mainly require internal record-keeping (for example, keeping signed resolutions and updating company registers). Other changes can trigger Companies Office filings (for example, certain changes to share capital or changes to a constitution that must be notified/updated on the register, depending on the type of change and how your company is set up).
The key is to treat the special resolution as one step in a compliance chain, rather than the final step. If you’re unsure what follow-on actions apply, it’s worth checking your specific situation with a corporate lawyer so you don’t miss a required filing or update.
Key Takeaways
- A shareholders special resolution is a formal shareholder decision that usually requires at least 75% approval under the Companies Act 1993 (with the threshold applying slightly differently depending on whether it’s passed at a meeting or by written resolution).
- You’ll commonly need a special resolution for major company changes like amending the constitution, changing shareholder rights, or for other decisions where the Companies Act, your constitution or your shareholders agreement sets that higher threshold.
- To pass a special resolution properly, you should check your constitution and shareholders agreement, draft clear wording, use the correct process (meeting or written resolution), meet the approval threshold, and record it in company records.
- Common issues include using the wrong resolution type, not following procedure, relying on informal approvals, and having inconsistent company records.
- Special resolutions work best when your company governance is set up properly, including a consistent Shareholders Agreement and Company Constitution.
- If you’re planning growth events (like raising capital or selling the business), keeping your corporate records tidy can prevent delays and reduce legal risk during due diligence.
