Paid Sick Leave Entitlements and Obligations for NZ

When you’re running a small business, sick leave can feel like one of those “simple” HR topics that suddenly becomes complicated the moment someone actually needs time off.

You might be asking:

What exactly counts as paid sick leave in New Zealand?
Who is entitled to it (and when)?
How do you manage proof, payroll, and ongoing performance fairly?
What are your options if a pattern starts impacting operations?

Getting this right matters for two reasons. First, because you have legal obligations under New Zealand employment law. Second, because clear, consistent sick leave processes protect your business from misunderstandings, disputes, and avoidable disruption.

This guide breaks down paid sick leave for employers in a practical, plain-English way - including entitlements, evidence rules, record-keeping, common pitfalls, and best-practice steps to keep your workplace compliant and running smoothly.

What Is Paid Sick Leave In New Zealand (And Why It Matters For Employers)?

Paid sick leave is time off work where you continue to pay an employee because they are:

sick or injured; or
caring for a spouse/partner or someone who depends on them, who is sick or injured.

In New Zealand, minimum sick leave entitlements come from the Holidays Act 2003. Even if your business is small, you still need to meet these minimum standards.

From an employer perspective, paid sick leave isn’t just a “benefit” - it’s a compliance obligation. If you get it wrong (for example, by declining sick leave when the employee is entitled, or paying it incorrectly), you can end up facing:

wage and leave arrears;
penalties or enforcement action (in more serious cases); and
employment relationship issues (including grievances) that cost time and money.

The good news: with clear employment documents and a consistent process, sick leave management becomes much more predictable.

Which Employees Are Entitled To Paid Sick Leave (And When Does It Start)?

One of the most common questions we hear from business owners is whether new staff, casual staff, or part-timers are entitled to paid sick leave.

Eligibility: The “6-Month” Rule

In general, an employee becomes entitled to paid sick leave after 6 months of continuous employment, provided they meet the eligibility tests under the Holidays Act 2003.

In practical terms, most employees become entitled after 6 months if they have also met the Act’s minimum work pattern test (for example, over that period they’ve worked an average of at least 10 hours per week, and at least 1 hour in every week or at least 40 hours in every month).

Once they meet eligibility, they receive their sick leave entitlement and then receive it again after each subsequent 12-month period (again, subject to the Act’s rules).

How Much Paid Sick Leave Do Employees Get?

The statutory minimum is commonly understood as:

10 days paid sick leave per year (once eligible), and
unused sick leave can be carried over, up to a maximum balance of 20 days (unless your employment agreement provides more).

Your employment agreement can offer more than the legal minimum, but it can’t offer less.

What About Casual Employees?

“Casual” is often used differently by different businesses, so this is where employers can accidentally trip up.

Some casual employees won’t meet the eligibility tests due to genuinely irregular work. But others who are labelled “casual” may actually work regular hours and become entitled.

If your team includes casual staff, it’s worth checking that your documentation and payroll settings match reality. A properly drafted Employment Contract can help set expectations clearly and reduce confusion later.

Employees Versus Contractors

Paid sick leave is an employee entitlement, not a contractor entitlement. If you engage people as contractors, it’s important you’ve genuinely structured the relationship as contracting - misclassification risks can be significant.

If you’re not 100% sure, it’s worth tightening up your contracts and engagement process early, especially if you’re growing quickly.

How Do You Calculate And Pay Sick Leave Correctly?

From an operational perspective, the biggest pain point usually isn’t approving sick leave - it’s paying it correctly and keeping accurate records.

What Rate Do You Pay Sick Leave At?

Generally, paid sick leave is paid at the employee’s relevant daily pay (or average daily pay, where appropriate under the Holidays Act rules).

This matters if someone’s hours vary, or if they earn commission, allowances, or variable pay. If you’re unsure which method applies, it’s worth getting advice, because “close enough” calculations can still lead to arrears later.

Do You Pay Sick Leave On Days They Don’t Work?

Typically, you only deduct sick leave if the employee was scheduled (or would otherwise have been expected) to work that day.

For example:

If an employee is sick on a normal rostered workday, that’s usually sick leave (if they’re eligible and have a balance).
If they’re sick on a day they weren’t going to work anyway, it generally shouldn’t be deducted.

Sick Leave Versus Working From Home

A common modern scenario: an employee is unwell but says they can “work from home and push through”.

As an employer, you should think about:

whether they’re actually fit to work (and whether working may worsen their condition);
health and safety risks (including fatigue and stress); and
whether you’re creating inconsistent expectations in your team (for example, pressuring people to work while sick).

If you do allow working from home while unwell, make sure it’s genuinely voluntary and not a substitute for proper sick leave where needed.

Can You Ask For A Medical Certificate (And When Should You)?

Most employers want to do the right thing - but you also need to protect your business from abuse of leave entitlements.

New Zealand law allows employers to ask for evidence in certain situations. The key is to do it lawfully and consistently.

When Can You Request Proof?

Under the Holidays Act 2003, you can generally require proof (for example, a medical certificate) if an employee takes sick leave for 3 or more consecutive calendar days (even if some of those days are not days the employee would normally work).

You can also ask for proof within the first 3 consecutive calendar days, but if you do, you generally need to pay the employee’s reasonable costs of getting that proof (and the request still needs to be reasonable in the circumstances).

Because these rules can be technical and fact-dependent, it’s a smart move to ensure your employment agreement and policies set out:

when proof can be requested;
what form of proof is acceptable; and
how costs will be handled if the request is made early.

This is one of those areas where having a tailored Employment Contract and a clear staff policy can save you a lot of back-and-forth later.

Privacy: Handle Health Information Carefully

If you’re collecting medical certificates or health information, you’re collecting sensitive personal information. That means you must handle it carefully and store it securely, including in line with the Privacy Act 2020.

As a practical baseline:

Only ask for information you actually need (usually, confirmation they’re not fit for work and the expected timeframe).
Limit who can access it internally.
Store it securely and don’t keep it longer than needed.

Even if you’re a small business without a dedicated HR team, getting your privacy basics right is essential. Having a Privacy Policy and internal process for handling employee data helps demonstrate you’re taking your obligations seriously.

What If An Employee Has Used All Their Sick Leave (Or Takes Lots Of Sick Days)?

This is where many small business owners feel stuck: you want to support your people, but you also need your business to function.

There are a few different situations to separate out.

1. The Employee Has No Sick Leave Left

If an employee has used all their paid sick leave, you have options - but you should approach it carefully and consistently.

Common approaches include:

Annual leave by agreement (if the employee wants to use it);
unpaid leave by agreement; or
alternative duties or adjusted working arrangements (where appropriate).

Try to avoid making on-the-spot decisions that aren’t documented, because that can create “custom and practice” expectations across your workplace.

2. There’s A Pattern Of Sick Leave (e.g. Mondays/Fridays)

Patterns happen for many reasons - sometimes legitimate (for example, ongoing health issues or family responsibilities), sometimes not.

As an employer, your best protection is to:

keep accurate attendance and leave records;
apply your rules consistently across the team;
have a calm conversation early, focused on support and expectations; and
ask for evidence when permitted and appropriate.

If you jump straight to disciplinary action without a fair process, you can expose your business to risk. If you ignore a genuine performance issue for too long, you can end up with bigger operational problems later.

3. Long-Term Illness Or Injury

If an employee is away for an extended period or has ongoing fitness-for-work issues, this can turn into a complex area involving:

medical incapacity;
potential accommodations and workplace adjustments; and
proper process before making any decisions about ongoing employment.

This is a situation where getting tailored advice early is worth it, because the “right” approach depends heavily on the facts, the role, and the medical situation.

How Should Employers Set Up Sick Leave Policies And Processes From Day One?

If you want fewer headaches when managing paid sick leave, the best time to set up your process is before your first sick day request lands in your inbox.

Put The Right Documents In Place

At a minimum, you should have:

a clear Employment Contract that references sick leave entitlements and your process; and
a staff handbook or workplace policies that explain how leave requests, proof, and communication should work.

This doesn’t need to be overly complicated - it just needs to be clear and tailored to how your business operates (rostering, shifts, remote work, who approves leave, and so on).

Include A Clear Process For Requesting Sick Leave

To avoid confusion, your sick leave process should cover:

how the employee must notify you (text, phone call, email, app);
when they must notify you (e.g. before their shift starts);
who they should notify (direct manager, business owner, roster manager);
when you may request medical proof; and
what happens if they can’t attend work and can’t make contact.

Train Your Managers (Even If That’s Just One Person)

In small businesses, the “HR department” is often you.

It’s still important to make sure anyone who approves leave understands:

when the employee is entitled to paid sick leave;
how to respond consistently;
what not to ask (for example, overly detailed medical information); and
how to document decisions properly.

Keep Good Records

Accurate leave records protect both you and your employees. If a dispute comes up later, clear records can make the difference between a quick resolution and a drawn-out process.

Make sure you track:

sick leave balances and entitlement dates;
when sick leave was taken and for how long;
any agreed alternative leave arrangements (annual leave/unpaid leave); and
any proof requested and received (stored securely).

Think About The Bigger Compliance Picture

Sick leave usually sits alongside other employment obligations like wages, hours, and workplace policies. If you’re scaling your team, it can be worth a broader check of your employment setup so everything aligns (contracts, policies, privacy handling, and termination processes if things go wrong).

If you need to formalise policies beyond sick leave (like conduct, confidentiality, privacy, and disciplinary processes), a workplace policy package can help you stay consistent as you grow.

Key Takeaways

Paid sick leave for employers in New Zealand is governed by the Holidays Act 2003, and you need to meet minimum entitlements even as a small business.
Employees generally become entitled to paid sick leave after 6 months (subject to the Holidays Act eligibility test), and sick leave can be used for the employee’s illness/injury or to care for certain dependants.
Paying sick leave correctly matters - especially where hours and pay vary - because incorrect calculations can lead to arrears and disputes.
You can request medical proof in certain situations, including after 3 consecutive calendar days, and if you ask for proof earlier you’ll generally need to cover the employee’s reasonable costs.
Health information is sensitive, so store it securely and only collect what you genuinely need, in line with good privacy practices and the Privacy Act 2020, supported by documents like a Privacy Policy.
If sick leave becomes frequent or problematic, focus on early, fair conversations and proper process - avoid snap decisions that can create legal risk.
The best protection is having clear employment documents from day one, including a tailored Employment Contract and workplace policies that set expectations for leave and evidence.
