Starting a charity is an exciting step - you’re building something designed to make a genuine difference.
But before you start fundraising, applying for grants, or launching programmes, you’ll want to get your legal foundations right. A well-drafted charity constitution helps you do exactly that. It sets the rules for how your charity runs, how decisions get made, and how you stay compliant as you grow.
This guide is updated for 2026 so you can feel confident you’re working from current New Zealand expectations around governance, privacy and accountability - without drowning in legal jargon.
Let’s walk through what a charity constitution is, when you need one, what it should include, and the common mistakes that cause delays (or disputes) later on.
What Is A Charity Constitution (And Why Does It Matter)?
A charity constitution is your organisation’s “rulebook”. It’s the formal document that sets out:
- what your charity exists to do (its purposes);
- how it will be governed (who is in charge and how decisions are made);
- how money and property will be managed; and
- what happens if the charity changes or winds up.
In practical terms, your constitution is one of the first documents banks, funders, platforms and regulators will ask for. It also becomes your reference point when there’s uncertainty - for example, if committee members disagree about spending, membership, conflicts of interest, or who has authority to sign contracts.
If you don’t set clear rules upfront, you can end up with:
- governance deadlocks (no one knows who can decide what);
- arguments about who controls funds or property;
- delays when registering with the right regulator; and
- higher legal costs later when you need to “undo” a messy setup.
Getting your constitution right from day one is one of the best ways to protect your mission, your people, and the communities you’re supporting.
Do You Need A Constitution To Register A Charity In New Zealand?
In most cases, yes - if you’re setting up a charity with a formal legal structure, you’ll need a governing document. The exact document depends on how you set up your charity.
Common Charity Structures And Their Governing Documents
- Incorporated society (often used for membership-based community groups): usually has a “constitution” (sometimes called rules).
- Charitable trust (often used where trustees manage assets or long-term projects): usually has a “trust deed”.
- Charitable company (less common, but sometimes used for larger charities or where a corporate structure is preferred): usually has a company constitution (and other governance documents).
Choosing the right structure is important because it affects control, liability, reporting obligations, and how you bring people into your organisation (for example, members vs trustees vs directors).
If you’re deciding between structures, it can help to think about:
- Will you have members with voting rights?
- Do you want a board-style governance model?
- Will you employ staff or mostly rely on volunteers?
- Will you own assets, manage grants, or hold property long-term?
If you’re building a charity that may grow into complex operations, it’s worth getting legal advice early - changing governance documents later can be doable, but it’s rarely quick or painless.
For charities that operate through a company (or alongside one), the governance rules often sit in a Company Constitution, which can work alongside charity-specific requirements (like charitable purposes and asset lock provisions).
What Should You Include In A Charity Constitution?
A strong charity constitution is clear, practical, and tailored to how you’ll actually run the organisation (not just a generic template).
While the exact clauses depend on your structure and activities, most New Zealand charity constitutions should cover the areas below.
1. Name, Purposes And Charitable Nature
This is the “why” of your charity.
- Name: your legal name (and any trading name, if relevant).
- Purposes: what your organisation exists to do (your charitable purposes).
- Not-for-profit nature: confirm that profits and assets are used to further the charity’s purposes, not distributed to individuals.
Be careful with wording here. If your purposes are too broad, vague, or include non-charitable aims, it can complicate registration and create governance confusion later.
2. Membership Rules (If You Have Members)
If your charity is membership-based, your constitution should spell out:
- who can become a member (eligibility criteria);
- how people apply and how membership is approved;
- membership fees (if any);
- how members can resign;
- when membership can be suspended or terminated (and the process); and
- members’ rights (including voting rights).
This section matters more than many people realise. If a dispute ever arises (for example, around voting, access to information, or disciplinary action), you’ll rely heavily on what your constitution says.
3. Governance: Board/Committee, Roles And Decision-Making
This is the heart of your constitution - it’s where you define who is responsible for running the charity.
Most constitutions cover:
- the governing body name (board, committee, trustees);
- how people are appointed, re-appointed, or removed;
- term lengths and rotation rules;
- office holder roles (chair, secretary, treasurer);
- meeting procedures and quorum requirements;
- voting rules (including casting vote rules, if any);
- delegations of authority (who can sign contracts and approve spending); and
- how you record decisions (minutes and resolutions).
One practical tip: think through “real-life” scenarios. For example, what happens if your chair resigns suddenly? Or if you can’t reach quorum for weeks? Or if two founders disagree? A tailored constitution helps avoid dead ends.
4. Money, Property And Financial Controls
Even small charities should have clear money rules - not because you expect problems, but because good governance builds trust with donors and funders.
Your constitution often deals with:
- how funds can be raised and applied;
- who controls bank accounts and payment approvals;
- financial reporting and record-keeping;
- how the charity can buy, sell, or lease assets; and
- whether the charity can reimburse expenses (and in what circumstances).
If you’ll be entering leases or using premises, your signing authority rules should align with what a landlord or lender will require - and if you’re negotiating premises, a Commercial Lease Review can be crucial to avoid locking your charity into risky terms.
5. Conflicts Of Interest (And How You Manage Them)
Conflicts of interest are common in the charity world - and they’re not automatically “bad”. They just need to be managed transparently.
Your constitution should address:
- what a conflict of interest is (including financial and non-financial conflicts);
- disclosure requirements (when and how to declare);
- how conflicted decision-makers are handled (e.g. they must not vote); and
- record-keeping (conflict register and minutes).
Having clear conflict rules helps protect both the charity and its decision-makers, especially when you start dealing with grants, supplier relationships, or paid staff.
Many charities also adopt a separate Conflict of Interest Policy to give more detail than a constitution typically includes.
6. Amendments: How You Change The Constitution
No constitution stays perfect forever. Your charity may evolve, and your governance rules may need to evolve too.
Make sure your constitution explains:
- who can propose an amendment;
- notice requirements (how far in advance members must be notified);
- voting thresholds (simple majority vs special resolution); and
- any requirement to notify or register changes with relevant bodies.
This is one of the most common areas where DIY constitutions fall over - they either don’t include an amendment process, or the process is too unclear to follow.
7. Winding Up And Asset Distribution (“Asset Lock”)
This is a big one for charities.
Your constitution should set out what happens if the charity winds up, including:
- how the decision to wind up is made;
- who is responsible for the process; and
- where remaining assets go.
For most charities, remaining assets should go to another organisation with similar charitable purposes (rather than to members, trustees, or founders). Getting this clause right is essential for protecting the charity’s integrity and meeting charitable expectations.
What Other Legal Documents Should Your Charity Consider?
Your constitution is a key starting point - but it’s rarely the only document you’ll need to run your charity smoothly.
Depending on what your charity does, you may also want:
Policies To Help You Run Day-To-Day
- Privacy compliance documents if you collect personal information (donors, service users, volunteers, beneficiaries). A clear Privacy Policy is often a baseline document for charities with websites, online donation tools, mailing lists, or client intake forms.
- Volunteer agreement if you rely on volunteers. This helps set expectations around roles, behaviour, expenses, confidentiality, and safety. A Volunteer Agreement can help reduce misunderstandings and protect your charity’s reputation.
- Whistleblower and complaint processes if you want strong internal accountability (especially important as you grow or handle sensitive services).
Employment Documents (If You Hire Staff)
If your charity hires employees, you’ll usually need properly drafted employment documents. It’s worth remembering that “charity” doesn’t mean you’re exempt from employment law.
A tailored Employment Contract helps clarify pay, duties, hours, IP/confidentiality, and termination processes, and can reduce the risk of disputes down the track.
Commercial Contracts (If You Operate Like A Business)
Many charities enter into contracts that look a lot like commercial arrangements - for example, with sponsors, suppliers, IT providers, venue hire companies, and service partners.
Even if you’re mission-driven, you still want clear written agreements so everyone knows what’s expected and what happens if something goes wrong.
What Laws Do Charities Need To Keep In Mind?
A constitution helps your charity operate consistently, but it sits within a wider legal framework. The exact laws that apply depend on your charity’s activities, structure, and whether you have staff, members, or regulated services.
Some common compliance areas include:
Privacy Act 2020
If your charity collects, uses, stores, or shares personal information, you’ll need to take privacy seriously. That could include:
- donor information and payment details;
- mailing list subscribers;
- volunteer records;
- service user or beneficiary data (which can be especially sensitive).
You’ll generally need to collect information fairly, store it securely, only use it for appropriate purposes, and respond properly to access/correction requests. This is also a trust issue - people support charities because they trust them.
Employment And Health And Safety Obligations
If you employ staff (or even engage contractors), employment and workplace health and safety responsibilities can kick in quickly. Even for volunteer-heavy organisations, you’ll want to think carefully about safe practices, supervision, and incident reporting.
In practice, this often means getting your internal documents aligned: clear role descriptions, reporting lines, and processes for performance and conduct concerns.
Consumer And Fundraising Communications (Fair Trading Considerations)
Charities often advertise fundraising campaigns, events, raffles, and donation appeals. While not every charity message is “advertising” in a technical sense, it’s still important that public-facing communications are accurate and not misleading.
If you’re making claims about how funds will be used, what donors will receive, or what impact a donation will achieve, you should make sure your statements are clear and supportable. This helps protect your reputation and reduces the risk of complaints.
Common Mistakes When Drafting A Charity Constitution (And How To Avoid Them)
It’s completely normal to feel unsure when you’re setting up governance documents - most founders haven’t done this before.
Here are some of the most common constitution issues we see, and what to do instead.
Using A Generic Template That Doesn’t Match How You’ll Operate
Templates can be a helpful starting point, but they often include clauses that don’t fit your charity (or miss key clauses you actually need).
What to do instead: map out how your charity will run in real life - how decisions will be made, who will be involved, and what risks you might face - then tailor the constitution to match.
Unclear Authority To Spend Money Or Sign Contracts
If your constitution doesn’t clearly say who can approve spending or sign agreements, you can run into major issues with banks, funders, and suppliers - and internal disputes are more likely too.
What to do instead: include clear delegation rules (e.g. board approval thresholds, two-signature rules, and defined office holder powers).
Weak Conflict Of Interest Rules
This is one of the fastest ways to lose trust. Even where no one has bad intentions, a lack of process makes decisions look questionable.
What to do instead: require disclosures, manage voting/participation, and document conflicts properly.
Not Planning For Change (Amendments, Growth, And Succession)
Many charities start with a small founding group. Later, you might bring on new members, funders, trustees, or partners - and your constitution should be able to support that growth.
What to do instead: build in a workable amendment process and practical appointment/removal rules so you aren’t stuck later.
Forgetting About Digital Operations
In 2026, most charities handle at least some operations online - donations, email newsletters, social media, volunteer onboarding, event registrations.
What to do instead: make sure your constitution and related policies anticipate modern data handling, online communications, and approvals (especially if you use cloud tools and remote board meetings).
Key Takeaways
- A charity constitution is your organisation’s governance rulebook - it helps prevent disputes, supports compliance, and builds trust with donors and funders.
- Your constitution should clearly set out your charitable purposes, not-for-profit nature, governance structure, decision-making rules, and financial controls.
- Strong clauses around conflicts of interest, amendments, and winding up (including an asset lock) are essential to protect your charity long-term.
- Most charities also benefit from supporting documents like a Privacy Policy, volunteer agreements, and employment contracts if they hire staff.
- Charities still need to consider key legal obligations like privacy compliance (Privacy Act 2020), employment requirements, and accurate public communications.
- Avoid using one-size-fits-all templates - a tailored constitution is one of the best ways to be protected from day one.
