Continuous Employment In New Zealand: Calculating Continuous Service After Breaks

If you’re running a small business, “continuous employment” can sound like one of those HR phrases you only hear when something goes wrong - a resignation, a restructure, a leave dispute, or a payroll question you didn’t see coming.

But in practice, continuous employment (also commonly called “continuous service”) sits underneath a lot of day-to-day employment decisions in New Zealand. It can affect when employees qualify for certain entitlements, what happens when there’s a gap between engagements, and how you should treat changes like restructuring, temporary closures, or employees moving between related businesses.

In this guide, we’ll break down what continuous employment generally means, how to think about common “break” scenarios, and what you can do to reduce risk (and admin headaches) as your team grows.

Important: This article is general information only and isn’t legal advice. Leave and holiday pay calculations can be technical under the Holidays Act 2003 and often depend on the facts (and on payroll set-up), so it’s worth getting advice if you’re unsure.

What Does “Continuous Employment” Mean For A New Zealand Employer?

In simple terms, continuous employment generally refers to an employee’s unbroken period of service with you as their employer.

This matters because many employee rights and entitlements hinge on time - for example, whether the employee has been employed for a certain minimum period, or how long they’ve been in the role when something changes (like a restructure or termination).

There isn’t always a single definition that applies in every situation, because different laws and entitlements can treat continuity slightly differently. For most small businesses, though, the practical question is:

• Has the employment relationship continued without being ended and restarted?
• If there was a “break”, was it a true termination, or just time away from work under an ongoing employment agreement?

One common misunderstanding is assuming that a period where an employee doesn’t work automatically equals a “break in service”. That’s not necessarily true.

For example, an employee may be away from work but still remain continuously employed if they are:

• on annual leave
• on sick leave
• on parental leave (or other approved leave)
• stood down temporarily in a way that doesn’t end the employment relationship
• on an unpaid leave arrangement that both sides agreed to (though unpaid leave can affect some Holidays Act calculations and, in some cases, anniversary timing)

This is why having a clear Employment Contract is so important - it sets out how the relationship works in the real world, including what happens when someone is away from work, how leave is taken, and what you treat as resignation/termination.

Why Does Continuous Employment Matter For Employee Entitlements?

From an employer’s perspective, continuous employment matters because it often affects:

• when leave entitlements kick in (and how they’re calculated);
• notice and termination processes (and how you handle final pay and accrued entitlements);
• redundancy and restructure planning (especially around what employees are entitled to under their agreement);
• risk management - because employment disputes often turn on whether service was continuous or broken.

Here are a few practical examples of where continuous service tends to become important:

1) Holiday And Leave Entitlements

In New Zealand, annual holidays generally become available after the employee completes 12 months of continuous employment, and then continue to become available on each anniversary date (with “holiday pay” calculations applying when the leave is taken).

Other leave types (like sick leave) have their own eligibility rules. For example, sick leave generally becomes available after 6 months of employment, but the Holidays Act has specific criteria around what counts as “6 months” (and there are also ongoing rules about carrying over sick leave).

So if you’re not sure whether someone’s employment has been continuous - particularly if they’ve left and come back - it can directly impact what you should be paying, what leave should be available, and what you should show in payroll records.

2) Termination And Final Pay

If employment ends, you’ll often need to calculate outstanding entitlements in the final pay (for example, annual holiday pay, alternative holidays, and any other contractual payments).

Where small businesses can get tripped up is when the employee “kind of left” but also “kind of didn’t”. For instance, if someone stops turning up, or you stop rostering them, but nobody clearly ends the employment relationship in writing.

Having a clean process (and clear documentation) is a big part of reducing risk when employment ends - whether it’s resignation, termination, or redundancy. If you’re dealing with termination scenarios, it can help to have the right documents and process in place early, such as an employee termination documents suite.

3) Business Changes (Restructures, Sales, Or Transfers)

Continuous employment issues also pop up when:

• you sell your business and employees move to a buyer
• you restructure and “re-hire” into new roles
• you operate through multiple entities (e.g. separate companies for different parts of the business)
• you acquire another business and take on staff

These scenarios can be legally complex. Whether service is recognised as “continuous” can depend on how the change is structured, what the old and new employer agree, and (in some industries) whether specific employee transfer protections apply (for example, Part 6A of the Employment Relations Act, which can preserve employment on transfer for certain “vulnerable workers”). If you’re buying or selling, it’s worth getting advice early and using documents tailored to the deal (including, where relevant, an Asset Sale Agreement).

Is There A “Break” In Continuous Employment If Someone Isn’t Working?

Not automatically.

A key point for employers is this: continuous employment is about whether the employment relationship continues, not whether the employee is physically working shifts every week.

Here are common scenarios that look like breaks, but often aren’t.

Approved Leave (Paid Or Unpaid)

If the employee is on authorised leave (annual leave, sick leave, parental leave, or an agreed unpaid leave arrangement), they are generally still employed. That means the service may remain continuous.

That said, some types of unpaid leave can still have practical impacts under the Holidays Act - for example, it may affect some pay calculations, and in some cases extended periods of unpaid leave can affect the timing of annual holiday entitlement dates. Because the rules can be technical, it’s worth checking your specific situation.

From a business perspective, the most important thing is to have:

• a written agreement or written confirmation of the leave arrangement;
• payroll records showing how the time away was treated;
• clarity on whether the employee is expected to return and when.

Temporary Closure Or Stand-Down (Where Employment Continues)

Some businesses experience seasonal downtime, renovations, supply disruptions, or unexpected closure periods.

These situations can create a temptation to “pause” someone’s employment informally. The problem is: informal arrangements are where disputes start.

If you’re considering a stand-down or temporary reduction in hours, you should be careful and get advice because the legal position depends heavily on the facts and your employment agreement terms. You can also sanity-check your approach against concepts like employee stand down and whether you’re effectively varying the employee’s role or hours.

Reducing Hours Or Changing Rosters

If an employee’s hours reduce significantly, that doesn’t necessarily end their employment - but it can create legal risk if you change hours without following a proper process or without agreement.

This is especially important if you move someone from regular hours to “as needed” hours, because you may inadvertently create arguments about whether they were effectively dismissed, whether they remained employed, or whether the employment relationship changed in a way that wasn’t agreed.

If your business needs to cut back hours, it’s worth understanding your obligations and options, including in scenarios involving reducing staff hours.

When Does A Break Actually End Continuous Employment?

Generally, continuous employment ends when the employment relationship ends - for example, via resignation, termination, or a mutual agreement to end employment.

Where it gets tricky is when there’s a “gap” and then a return to work, and everyone treats it casually without documenting what happened.

Here are scenarios that commonly do break continuity (or at least raise a serious question about it):

1) A Clear Resignation Or Termination

If the employee resigns, and the employment ends, then any later re-hire is typically a new period of employment (unless there is a specific agreement or legal reason to treat it otherwise).

If you’re dealing with a resignation situation that is messy (like someone walking out), you’ll want to be careful - because the way you respond and document the exit can affect whether the employment relationship truly ended, and what you owe in final pay.

It’s also worth understanding notice expectations and whether any payment arrangements apply, including situations involving payment in lieu of notice.

2) Fixed-Term Contracts That End (And Are Not Renewed)

Fixed-term employment can create confusion about service. If a genuine fixed-term agreement ends, and there’s a gap, and then the employee is later re-hired, continuity may not carry through.

But if the fixed term was not set up properly, or the “end” wasn’t managed cleanly, you may face arguments that the employee was really ongoing.

Because of the risks here, fixed-term employment needs to be handled carefully from day one (including recording the genuine reason for the fixed term, and managing expiry correctly). If you’re using fixed-term arrangements, it’s worth reviewing whether your current approach aligns with best practice.

3) Casual Employment With Long Gaps

Casual work is another common area where small businesses stumble. If someone is genuinely casual, they may have irregular work and gaps between shifts.

But if the person works a regular pattern over time, they may not really be casual - and their entitlements (and what “continuous employment” looks like) can become disputed.

If you use casual staff (hospitality, retail, labour-based industries), make sure you understand the difference between true casual work and a regular part-time arrangement, because misclassification can lead to backpay risks and employment claims.

How Do You Calculate Continuous Service After A Break?

There isn’t a one-size-fits-all formula, because it depends on what the “break” actually was.

That said, for practical small business decision-making, you can often work through it using a structured approach.

Step 1: Confirm Whether Employment Actually Ended

Ask:

• Was there a resignation letter or termination letter?
• Was final pay processed as though employment ended?
• Did you remove them from payroll (or did they remain employed but unpaid)?
• Did you communicate an “end date” in writing?

If the answer is “yes, employment ended”, then continuous employment generally ends on that date, and any later engagement is likely a new employment period.

Step 2: Identify What The Gap Period Was

If employment did not end, clarify what the employee was doing during the gap:

• Were they on leave? (paid/unpaid)
• Were they temporarily not rostered, but still employed?
• Was there a dispute or misunderstanding about whether they had resigned?
• Was there a closure or stand-down?

This is where written records matter. Even a simple email confirmation of “unpaid leave from X to Y with return date Z” can save you a lot of grief later.

Step 3: Apply The Relevant Entitlement Rule

Different entitlements have different triggers and calculations. For example:

• Annual holidays generally focus on whether the employee has reached an anniversary date (and the Holidays Act then has specific rules about “weeks” of entitlement and how holiday pay is calculated when the leave is taken).
• Sick leave eligibility depends on meeting the Holidays Act criteria (commonly after 6 months, but the way “6 months” is satisfied can vary depending on work patterns).
• Contractual benefits (like bonuses or extra leave) may be defined in the employment agreement, and your agreement might specify what counts as “service”.

Because of this, it’s smart to check:

• the Holidays Act rules relevant to that entitlement; and
• the wording in the employee’s employment agreement.

If you’re not sure, it’s better to get advice early rather than “guess and hope for the best” - especially where payroll calculations are involved, because errors can compound over time.

How Can You Protect Your Business When Employment Is Interrupted?

Most continuous employment issues aren’t caused by bad intentions - they’re caused by fast-moving business realities. Someone stops turning up. You close for renovations. You move a staff member into a different entity. You rehire someone after a few months.

The easiest way to protect your business is to treat every “break” as a documentation moment.

Put Agreements In Writing (Even When You Trust The Person)

If someone is taking unpaid leave, moving to reduced hours, or pausing work, confirm:

• the start and end date (or the review date);
• whether the employment relationship continues;
• how pay and leave will be handled during the period;
• what the return-to-work plan is.

This isn’t about being formal for the sake of it - it’s about preventing misunderstandings that become legal disputes later.

Use Clear Employment Agreements For Every Role Type

Many continuity disputes start because the business has inconsistent documents across staff, or because roles evolved without updating the paperwork.

A well-drafted employment agreement should clearly describe the nature of the role (permanent, fixed-term, casual), hours, duties, and how changes will be handled.

Even if you’re only hiring one person, having the right foundations matters. If your documents are out of date, a quick review can often uncover hidden risks early.

Be Careful When Moving Staff Between Related Entities

If you operate through multiple companies (or you’re changing ownership structure), it can get complicated quickly. An employee might think they’re still continuously employed “by the business”, while the legal employer (on paper) is different.

This is where you should get advice, because the structure and documents used can affect liability and employee entitlements. If you’re changing how the business is owned or operated, it may also be relevant to look at broader structuring work (like a Company Set Up), so your employment arrangements match the entity that actually employs staff.

Plan Ahead For Business Sales Or Restructures

If you’re buying, selling, or restructuring, continuous employment issues can impact:

• which entity is responsible for employee entitlements;
• what you need to disclose during negotiations;
• how employees transfer (if they transfer at all);
• what consents or documents are required (including, in some cases, compliance steps where statutory transfer protections apply).

Getting the transaction documents right (and aligning them with what happens to employees in practice) helps avoid “surprises” after the deal completes.

Key Takeaways

• Continuous employment is about whether the employment relationship has continued without ending - it’s not just about whether someone worked every week.
• Many “breaks” (like annual leave, sick leave, parental leave, or agreed time off) don’t necessarily break continuous service if employment still exists, though some unpaid leave can affect certain Holidays Act calculations and (sometimes) anniversary timing.
• Continuous service often affects leave entitlements, payroll calculations, termination outcomes, and restructure planning, so it’s worth getting right early.
• Where an employee leaves and later returns, the key question is whether there was a true termination/resignation and whether you documented it clearly.
• Casual and fixed-term arrangements can create continuity confusion, especially where the real working pattern doesn’t match what the paperwork says.
• The best protection is strong documentation: clear agreements, written records when work is interrupted, and a process for exits and re-hires.
