Is It Illegal Not to Give Employees a Contract of Employment?

If you are hiring in New Zealand, one of the easiest mistakes to make is assuming a verbal agreement is enough, copying a casual template from overseas, or letting a new starter begin work before the paperwork is sorted. Those shortcuts can create real risk. A missing or non-compliant employment agreement can lead to disputes about pay, hours, duties, notice, trial periods and leave, often at the worst possible time.

The short answer is that New Zealand employers must provide a written employment agreement to every employee. You cannot simply rely on a handshake deal or a few emails. You also need to make sure the agreement includes the right minimum terms and that you give the employee a fair chance to seek advice before signing.

This guide explains what the law expects, when the agreement must be given, what needs to be included, and where businesses commonly get caught out before they hire their first worker or before they sign updated terms with an existing team member.

Overview

Yes, it is effectively unlawful in New Zealand to employ someone without giving them a written employment agreement. The Employment Relations Act 2000 requires every employee to have a written agreement, and employers must keep a signed copy or record that the employee was given the agreement. The bigger issue for most businesses is not just having a document, but making sure it is legally compliant and used properly.

• Every employee must have a written employment agreement.
• The employer must provide the agreement and give the employee a reasonable opportunity to get independent advice before signing.
• The agreement must contain mandatory terms, including an explanation of how to resolve employment relationship problems.
• Trial periods, availability clauses, deductions and restraint clauses only work if they are drafted correctly.
• A verbal promise can still create expectations, so your written contract should match what you actually offer.
• Misclassifying a worker as a contractor does not avoid employment law if the real relationship is employment.

What Is It Illegal Not to Give Employees a Contract of Employment Means For New Zealand Businesses

For New Zealand businesses, this means you should not let an employee start work until you have given them a compliant written employment agreement and a fair opportunity to review it. If you skip that step, you expose the business to avoidable legal and practical problems from day one.

Under New Zealand employment law, employers must have a written employment agreement with every employee. This applies whether the person is full time, part time, fixed term, or casual. It also applies whether you are hiring your first worker, adding a senior manager, or taking on someone for a short seasonal role.

The agreement can be an individual employment agreement or, in some cases, a collective agreement may apply first. If a collective agreement does not end up applying, the employee still needs an individual written agreement.

What the employer must do

Before you sign a contract with a new employee, the employer should:

• give the proposed employment agreement to the employee
• advise them that they are entitled to seek independent advice
• give them a reasonable opportunity to get that advice
• consider and respond to any issues the employee raises
• keep a signed copy of the final agreement, or a record that it was provided

This is not a box-ticking exercise. If you email a contract at 5 pm and expect it signed before a 9 am start the next day, that may not be a reasonable opportunity to seek advice, especially for a more complex role.

What must be in the agreement

A written employment agreement in New Zealand must include certain minimum terms. At a practical level, the document should clearly set out the working relationship so both sides know where they stand.

The agreement should usually cover:

• the names of the employer and employee
• a description of the work to be performed
• where the employee will work
• the agreed hours, or an indication of the arrangements relating to hours
• the wage or salary rate, or the method of calculating pay
• an explanation of how to help resolve employment relationship problems, including reference to the 90 day timeframe for raising a personal grievance
• a statement that the employer will comply with obligations around rest and meal breaks
• any other matters required by law, depending on the role and terms used

Many businesses also include clauses dealing with confidentiality, intellectual property, notice periods, leave administration, company property, social media, secondary employment and post-employment restraints. These extra clauses can be useful, but they do not replace the mandatory basics.

Can you rely on a verbal agreement?

No, not as a substitute for a written employment agreement. A verbal promise may still be relevant evidence of what was discussed, but it does not satisfy the legal requirement to provide a written agreement.

This is where founders often get caught. They speak with someone they know, agree on a start date and pay rate over coffee, and assume they can sort the document later. If the person starts work before you put proper written terms in place, you may end up arguing about what was agreed after the relationship has already soured.

What happens if you do not provide one?

The main risk is not just technical non-compliance. Without a proper agreement, disputes become harder to manage and your position becomes weaker if there is a disagreement over hours, notice, bonuses, duties or whether the person was on a valid trial period.

Potential consequences can include:

• penalties for failing to comply with minimum employment standards
• difficulty enforcing clauses that were never properly agreed
• increased risk of personal grievance claims
• arguments over whether the worker was permanent, casual or fixed term
• problems proving what was promised about pay, availability or notice
• reputational issues if onboarding practices are poor

For a small business, even a straightforward employment dispute can drain management time and cash flow. Getting the agreement right before the employee starts is usually much cheaper than fixing a dispute later.

Legal Issues To Check Before You Sign

Before you sign, the key question is not only whether there is a written contract, but whether the terms fit the real job and comply with New Zealand law. A generic document can be almost as risky as no document at all.

Employee or contractor?

Before you classify someone as a contractor, stop and look at the real working relationship. Calling a person an independent contractor in the document does not settle the issue if, in practice, they work like an employee.

Businesses should consider factors such as:

• who controls how, when and where the work is done
• whether the person can work for others
• whether they provide their own tools and take commercial risk
• how integrated they are into the business
• whether they are being paid for time worked rather than a defined result

If the relationship is really employment, you need an employment agreement and the worker gets the benefit of employment protections. Misclassification is a common issue for startups trying to stay flexible in the early stages.

Permanent, fixed term, casual or part time?

The contract should match the actual arrangement. If someone has regular weekly hours, calling them casual does not necessarily make them casual.

Fixed term arrangements need extra care. You must have genuine reasons based on reasonable grounds for ending employment at the end of the term or on a specified event, and those reasons need to be recorded in the agreement. A fixed term cannot be used simply to avoid normal employee rights.

Casual employment also needs careful drafting. If the employee in reality works regular and ongoing hours, the label may not hold up.

Trial periods and probation

A trial period only works if it is included in the written agreement and agreed before the employee starts work. If the employee does even a short period of work before signing, the trial period can fail.

Employers also need to check whether they are eligible to use a trial period under the current law at the time of hiring, because this area can change. Probationary periods are different. They can still allow performance to be assessed, but they do not remove the employee's ability to bring a personal grievance in the same way a valid trial period may.

Hours, availability and overtime

Unclear hours create some of the most common disputes. If you expect flexibility, the agreement should say exactly what that means.

Before you sign, check:

• whether hours are guaranteed, variable or rostered
• whether there is any genuine need for an availability clause
• whether compensation is offered if the employee must remain available beyond guaranteed hours
• how overtime is treated
• whether the pay structure still meets minimum wage rules for all hours worked

Founders often use broad wording like “reasonable additional hours as required”. That can be risky if the role routinely demands long unpaid hours without clear agreement.

Pay, deductions and benefits

The agreement should spell out how much the employee is paid, when they are paid, and what the pay covers. If you want the ability to make deductions in limited situations, such as for unreturned equipment or overpayments, the clause needs to be lawful and carefully drafted.

You should also make sure any bonus, commission or incentive wording is clear about:

• when the entitlement arises
• whether it is discretionary or guaranteed
• what happens if the employee resigns or is under notice
• how disputes about calculations will be handled

If payroll or tax treatment is involved, speak with an accountant or tax adviser as well.

Confidentiality, IP and restraints

If the employee will access customer lists, pricing, code, product plans or other valuable information, the contract should deal with confidentiality and intellectual property ownership. This matters especially for tech businesses, agencies, product companies and founder-led teams where employees create material central to the business.

Restraint clauses, such as non-solicitation or non-compete clauses, need special care. They are not automatically enforceable just because they appear in the contract. The clause must be reasonable in scope and necessary to protect legitimate business interests.

Policies and consistency

The contract should also work with your workplace policies. If your leave, flexible working, disciplinary, privacy or IT usage policies say one thing and the contract says another, disputes are more likely.

Before you rely on a verbal promise to close the hire, check that your offer, contract, onboarding messages and internal policies all line up. Inconsistency is often what turns a minor issue into a formal employment problem.

Common Mistakes With Is It Illegal Not to Give Employees a Contract of Employment

The most common mistake is thinking any written contract will do. In practice, many disputes happen because the agreement is late, copied from the wrong jurisdiction, or does not reflect how the person actually works.

Letting the employee start before signing

This is one of the biggest mistakes for small businesses. Once the employee has started, some clauses become much harder to rely on, especially a trial period.

If you are moving quickly and need someone urgently, it is still worth pausing before they begin work. A rushed start can create months of legal uncertainty.

Using an overseas template

A UK or Australian template may look close enough, but New Zealand employment law has its own mandatory requirements and wording expectations. Terms about leave, grievance processes, trial periods and minimum standards can all be wrong or incomplete.

This often happens when a founder downloads a template from the internet or reuses the contract from a previous employer. That shortcut can leave key New Zealand protections out of the document.

Calling someone casual when they are not

If a worker has regular weekly shifts and an ongoing expectation of work, a casual label may not reflect reality. This can affect leave, notice, availability and termination issues.

The written agreement should describe the arrangement honestly. If the business model changes, update the contract rather than keeping an outdated label for convenience.

Including a fixed term without proper reasons

A fixed term employee cannot simply be ended at a chosen date because it suits the business. The reason for the fixed term must be genuine and based on reasonable grounds, and the agreement needs to record both the way the employment will end and the reasons for that term.

This is where employers often get caught when they hire for “three months to see how it goes”. That is usually not a valid reason on its own.

Drafting vague duties and hours

If the job description is too broad and the hours are unclear, arguments often follow about whether the employee was required to do a task, travel, work weekends, or accept reduced hours. Precision matters.

Good drafting does not mean making the contract rigid. It means setting clear expectations while preserving flexibility where the business genuinely needs it.

Trying to contract out of minimum rights

You cannot use an employment agreement to remove minimum legal entitlements. Terms that undercut minimum wage, holidays, rest breaks, sick leave or other protected rights are a problem, even if the employee signed them.

This is one reason a short, home-made contract can be risky. It may look simple, but if it cuts across minimum standards, it can cause more trouble than it solves.

Forgetting to update contracts as the business grows

A business may start with a simple team structure, then add remote work, incentive plans, access to sensitive information, or management responsibilities. If the contract stays stuck in the early-stage version, it may no longer protect the business properly.

Review your employment agreements when:

• roles become more senior
• staff move to hybrid or remote work
• the business starts offering commission or bonuses
• employees begin creating valuable IP or handling key client accounts
• you expand into new regions or change operating hours

Updated contracts should still be introduced properly. Existing terms usually cannot just be changed unilaterally.

FAQs

Do all employees in New Zealand need a written employment agreement?

Yes. Every employee should have a written employment agreement, whether they are full time, part time, casual or fixed term.

Can an employee start work before signing the contract?

They can physically start work, but that creates risk for the employer. You should provide the agreement and have it signed before the employee starts, especially if you want to rely on a trial period.

Is an email offer enough?

No, not by itself. An email can record part of the arrangement, but it does not replace a proper written employment agreement that includes the required terms.

What if the employee refuses to sign?

You should not ignore the issue. Engage with the employee, give them a reasonable chance to get advice, and try to resolve any concerns. If no agreement is reached, get legal advice before allowing the employment relationship to continue on uncertain terms.

Can I use the same contract for every worker?

Not always. A base template can help, but the final agreement should match the actual role, hours, seniority, pay structure and risk profile of that worker.
