If you’re building a startup in New Zealand, it’s normal to want to offer equity early. You might be bringing on a co-founder, hiring your first key employee, or setting up incentives for the team that’s about to do the hard yards with you.
But equity can get messy fast if you don’t set the rules upfront.
That’s where a vesting period comes in. A well-designed vesting period can help you reward people who stay and contribute, protect your cap table if someone leaves early, and make your business more investable.
Below, we’ll walk you through how vesting periods typically work in New Zealand, what choices you’ll need to make as a business owner, and what legal documents usually sit behind a vesting arrangement.
What Is A Vesting Period (And Why Do Startups Use It)?
A vesting period is the timeframe over which a person earns their equity entitlement. Instead of someone receiving (and keeping) all of their shares on day one, they become entitled to the shares gradually over time, usually as they continue working in the business and meeting expectations.
From a small business owner or founder perspective, a vesting period is mainly about:
- Retention: giving people a reason to stay long enough for the business to benefit from their contribution.
- Fairness: aligning rewards with actual time and effort invested.
- Risk management: protecting the company if someone leaves early, underperforms, or there’s a falling-out.
- Investor readiness: showing that founder and team equity is structured sensibly, so the cap table doesn’t become a “clean-up” job later.
Without a vesting period, you can end up in an awkward (and expensive) position where someone who only contributed briefly still owns a meaningful chunk of your company.
And once shares are issued, it can be difficult to unwind without clear contractual rights (and the necessary company approvals) to buy them back, require a transfer, or otherwise deal with unearned equity.
How Vesting Periods Are Commonly Structured In New Zealand
There isn’t one “official” NZ template for equity vesting. But in practice, a vesting period is usually structured around a few common building blocks.
1) The Overall Vesting Period Length
Many startups use a vesting period of 3 to 4 years, but this is commercial, not a legal requirement.
Shorter vesting periods can work for senior hires who are already proven, or where you want a faster reward cycle. Longer vesting periods are often used when the equity grant is sizeable or the role is critical to long-term growth.
When you’re deciding on a vesting period, ask yourself:
- How long will it realistically take for the person’s contribution to “pay off” for the business?
- How difficult would it be to replace them if they left?
- Will the vesting period still make sense if your business raises capital or changes direction?
2) The “Cliff” (If You Use One)
A vesting period often includes a cliff. This is the initial period where nothing vests, and once the cliff is reached, a portion vests at once.
A common example is a 12-month cliff within a 4-year vesting period.
Why do business owners like cliffs? Because they reduce the risk of issuing equity to someone who leaves quickly (or turns out not to be the right fit) before they’ve made a meaningful contribution.
3) Ongoing Vesting After The Cliff
After the cliff, vesting can happen in different ways, such as:
- Monthly vesting: smaller, regular increments (often seen as fair and predictable).
- Quarterly vesting: slightly chunkier increments, less admin.
- Milestone-based vesting: equity vests when a specific project or performance goal is achieved (more complex to draft properly).
Milestone-based vesting can be powerful, but it needs very clear definitions. If a milestone is vague (for example, “increase revenue significantly”), you can end up with disputes that damage your culture and distract from growth.
4) What Happens If Someone Leaves Before Vesting Completes?
This is the part that really matters.
A vesting period is only useful if your documents clearly say what happens when someone stops being involved in the business. Usually, you’ll need to decide how you want to handle:
- Unvested equity: typically, it is forfeited or never issued (depending on structure).
- Vested equity: the person may keep it, or the company/other shareholders may have buyback rights.
It’s common to build rules around “good leaver” vs “bad leaver” scenarios, but the definitions need to be drafted carefully and consistently across your documents (and in a way that fits with employment processes and your company’s governance requirements).
Founder Vesting vs Employee Vesting: What’s The Difference For Your Business?
It’s easy to think equity vesting is mainly an employee incentive tool. In reality, it often matters even more for founders, because founder equity stakes are typically large and can seriously affect investor confidence.
Founder Vesting
Founder vesting is often used to ensure that if a founder leaves early, they don’t walk away with a large permanent ownership stake while the remaining founder(s) do the heavy lifting.
Founder vesting is also a way to create accountability between co-founders, especially where contributions are expected to evolve over time (for example, one founder starts full-time later, or one founder is handling funding while another builds product).
This is usually documented through a combination of:
- a Founders Agreement that sets expectations, roles, and equity arrangements; and
- a Share Vesting Agreement that sets out the vesting mechanics and what happens on exit.
Employee Vesting
Employee vesting is typically about attraction and retention: offering a genuine upside to key hires when you may not be able to match larger companies on salary.
For employee equity, you’ll usually need to make sure the vesting terms align with (and don’t accidentally contradict) the person’s employment arrangements, including their duties and confidentiality obligations. This is where having a clear Employment Contract becomes important.
As a business owner, one practical point to think about is administration: who tracks vesting, who confirms milestones (if used), and what records you’ll keep to avoid disagreements later.
How Vesting Is Actually Implemented (Shares, Options, Or Vesting Conditions)
When people talk about a vesting period, they’re usually describing the commercial concept (“you earn equity over time”). Legally, you still need a structure that actually makes that happen.
In New Zealand, vesting is commonly implemented in a few ways (and the right one depends on your company’s stage, cap table, and fundraising plans). Because these arrangements affect share issues, transfers and (sometimes) financial assistance or buybacks, they need to be set up in a way that complies with the Companies Act 1993 and your company’s constitution (if you have one), and follows the correct board/shareholder approval process.
1) Issuing Shares Upfront, With Buyback/Transfer Mechanics
One approach is to issue the shares upfront, but make them subject to rules that allow the company (or other shareholders) to buy them back or require a transfer if the person leaves before they vest.
This approach can work, but it needs careful drafting to make sure the mechanism is clear, enforceable, and consistent with your governance documents (including any required approvals and solvency requirements that apply to share buybacks).
It also raises practical questions, like:
- How is the buyback price calculated (nominal value, fair market value, or something else)?
- Who is the buyer (the company, existing shareholders, or both)?
- What approvals are required to trigger the buyback or transfer?
2) Granting Options That Vest Over Time
Another common approach is to grant options (a right to acquire shares later), and the options vest over the vesting period.
This can be cleaner from a cap table perspective, because the person doesn’t become a shareholder until they exercise their options (subject to your plan rules).
If you’re exploring this pathway, you may want to consider whether you need something like an employee share scheme or option plan, and how it will interact with your future funding rounds. It’s also important to get tax advice early: employee share schemes and options can have material tax consequences in New Zealand, and the “right” structure often depends on the specific facts.
3) Agreeing To Issue Shares In The Future As Vesting Occurs
Sometimes, startups don’t issue anything upfront. Instead, the agreement says that shares will be issued progressively as vesting milestones are reached.
This can reduce early-stage complexity, but you must still be careful about:
- what happens if the company is sold during the vesting period;
- whether there are any triggers for accelerated vesting (if you want them); and
- how you document board/shareholder approvals for future share issues.
Because these structures can affect shareholding and control, your Company Constitution (if you have one) and shareholder arrangements should line up with the vesting terms.
What Legal Documents Do You Need To Support A Vesting Period?
The vesting period itself is only one part of the picture. The bigger goal is to ensure the arrangement is clear, enforceable, and doesn’t create unexpected consequences for the business later.
Common documents we see used in NZ startups include the following.
Share Vesting Agreement Or Equity Vesting Terms
This is usually the key document that defines:
- the vesting period and vesting schedule (including any cliff);
- what counts as “continued service” (employee, contractor, director, consultant, etc.);
- good leaver / bad leaver rules (if used);
- what happens to vested vs unvested equity on exit; and
- any acceleration events (for example, a sale of the business).
Shareholders Agreement
If you have multiple shareholders, a Shareholders Agreement often sets the ground rules for things like decision-making, transfers of shares, and what happens if someone wants to exit.
Vesting provisions and buyback/transfer rights often need to “plug into” these rules, so the documents don’t contradict each other.
Company Constitution (If You’re Using One)
Your constitution can include rules about share issues, share transfers, and shareholder rights. If your vesting arrangement relies on share buybacks or transfer restrictions, you want to make sure your Company Constitution is consistent with the equity deal you’re offering.
Employment Contract Or Contractor Agreement
Where someone is earning equity because they’re working in your business, you should make sure their underlying work relationship is properly documented.
For employees, that usually means a tailored Employment Contract.
For contractors or consultants, you’ll typically want a contractor agreement or consulting agreement that clearly covers deliverables, IP ownership, confidentiality, and the fact that they’re not an employee (where that’s the intention).
IP Ownership Terms (So The Business Actually Owns What’s Being Built)
This is a big one that founders sometimes miss.
If someone is earning equity because they’re building product, writing code, designing branding, or creating systems, you’ll want to make sure the company actually owns the IP being created (or has the right licences).
Otherwise, you can end up with someone leaving early, keeping their IP rights, and your business being unable to continue using what it paid for (even if it “paid” in equity).
Depending on your setup, this can be covered through employment/contractor terms and/or a separate IP assignment or licence arrangement.
Common Vesting Period Mistakes That Can Cost You Later
A vesting period can be a powerful protection tool, but only if it’s thought through properly.
Here are some of the most common mistakes we see when startups try to set vesting up informally (or rely on a handshake).
1) Agreeing On Vesting But Not Documenting It Clearly
If the vesting rules aren’t written down in a signed agreement, you’re left relying on memory and goodwill. That can fall apart quickly if the relationship changes.
In disputes, unclear arrangements often lead to expensive negotiations, reputational damage, and time you really can’t afford to lose as a growing business.
2) Issuing Shares Without A Practical Way To Deal With Unvested Equity
Once shares are issued, you can’t simply “take them back” because someone leaves.
If you want buyback rights, transfer obligations, or other mechanisms to deal with unearned equity, these need to be properly drafted, legally workable under the Companies Act 1993, and consistent with the rest of your company’s legal framework (including your constitution and any required approvals).
3) Not Thinking Through “Good Leaver / Bad Leaver” Scenarios
Business owners often want a simple rule like “if you resign, you lose everything.”
In practice, you’ll want to think through different exit scenarios, such as:
- the person leaves due to illness or family reasons;
- you terminate employment for underperformance (and whether a performance process was followed);
- there’s misconduct;
- the role becomes redundant; or
- the person leaves because the business pivots and their role no longer exists.
These details matter because the more discretion and ambiguity there is, the more likely you’ll end up in conflict (especially when equity becomes valuable).
4) Not Considering What Happens On A Sale Or Investment Round
Imagine you’re 18 months into your vesting period and a buyer wants to acquire your company, or an investor wants to come in.
If your vesting terms are unclear about what happens on a “change of control” event, you can end up with:
- key people leaving right when you need them;
- misaligned incentives during a sale process; or
- investors asking you to restructure the cap table under pressure.
There’s no single right answer here (some companies use acceleration, some don’t), but you want to decide it deliberately, not accidentally.
5) Forgetting The Human Side Of Vesting
Vesting is legal and commercial, but it’s also cultural.
If your team doesn’t understand how the vesting period works (or feels it’s unfair), it won’t motivate them the way you intended.
Plain-English explanations and consistent administration go a long way to keeping things smooth.
Key Takeaways
- A vesting period is the timeframe over which equity is earned, helping you reward real contribution while protecting your startup if someone leaves early.
- Vesting periods in NZ are usually structured with a defined term (often 3–4 years), sometimes with a cliff, and then ongoing vesting monthly/quarterly or by milestone.
- Founder vesting can be just as important as employee vesting, because it protects the cap table and makes your business more attractive to investors.
- How you implement vesting (shares upfront vs options vs future share issues) affects your control, administration, and ability to unwind arrangements if things change.
- Vesting should be supported by the right documents, such as a Share Vesting Agreement, Shareholders Agreement, Company Constitution, and a clear Employment Contract where relevant.
- Getting vesting wrong (or leaving it vague) can lead to disputes, messy exits, and difficult fundraising conversations later, so it’s worth setting it up properly from day one. Where options or employee share schemes are involved, it’s also worth getting tax advice early, because the tax outcomes can be significant.
