Employer Reference Letters in New Zealand: Legal Risks and Best Practices

A reference letter for employee from manager can feel like a routine favour, right up until it creates a legal problem. New Zealand employers often get caught by a few predictable mistakes: giving glowing statements they cannot back up, sharing sensitive information without thinking about privacy, or refusing references in an inconsistent way that creates tension after a resignation or dismissal. Another common issue is mixing opinion and fact so badly that no one can tell what the business is actually standing behind.

The good news is that reference letters do not need to be risky if you handle them properly. The safest approach is usually a clear, accurate and limited statement that reflects what the business genuinely knows. This guide explains what a manager should include, what should be left out, when written references are risky, and how New Zealand businesses can build a sensible process before they sign anything.

Overview

A reference letter is not legally required in every case, but once your business gives one, the contents matter. The main risks usually sit in accuracy, privacy, consistency and the possibility that another employer will rely on what you say.

• Confirm who is authorised to give references on behalf of the business.
• Check whether the letter contains facts you can prove, rather than assumptions or office gossip.
• Limit personal information to what is necessary and fair to disclose.
• Keep the wording consistent with your employment records, performance reviews and exit documents.
• Decide whether a short confirmation of role and dates is safer than a detailed character reference.
• Record when the reference was given, to whom, and in what form.

What Reference Letter for Employee from Manager Means For New Zealand Businesses

A reference letter from a manager is a business communication, not just a personal courtesy. If it is written on company letterhead, sent from a work email, or given by someone acting in a management role, the business may be treated as standing behind it.

That matters for startups and SMEs because informal practices can quickly turn into inconsistent risk. One founder gives only dates of employment, another manager writes a detailed recommendation, and a third refuses to respond at all. When there is no policy, businesses often create unnecessary exposure.

What a reference letter usually does

In practice, a reference letter generally serves one or more of these functions:

• confirming that a person worked for the business
• describing their position, reporting line or core duties
• stating the dates of employment
• commenting on work quality, reliability or conduct
• supporting an application for a new role, promotion or professional opportunity

Some employers ask for an open-ended written reference. Others ask for a targeted letter responding to a specific role. The second option is often easier to control because the manager can keep the comments relevant and factual.

Is an employer required to provide a reference?

Usually, no. New Zealand employers are not generally under a broad legal duty to provide a flattering written reference on request. The employment agreement, workplace policy, settlement terms or a specific commitment made during an exit process may affect that position, so you should check those documents before you refuse or agree.

If your business has promised a reference in a termination arrangement or record of settlement, the wording matters. A promise to provide a neutral statement is very different from a promise to provide a positive recommendation.

Why founders and managers should treat references carefully

The main issue is reliance. A future employer may rely on the reference when deciding whether to hire the person. The employee may also rely on it if it affects their ability to get work. That creates risk if the letter is misleading, careless, unfairly negative or inconsistent with your records.

This is where businesses often get caught after a messy exit. A manager may feel pressure to be kind, or pressure to warn the next employer, and ends up writing something that is hard to justify. Before you sign, ask whether every meaningful statement in the letter is something the business can support with actual information.

What a safer business reference looks like

A safer reference letter for employee from manager is usually short, factual and deliberate. It generally focuses on matters the manager directly observed or can verify from business records.

That might include:

• the employee’s job title
• the period they worked for the business
• a brief description of responsibilities
• high-level comments on performance that match documented reviews
• an accurate statement about whether they resigned, if that is relevant and appropriate

It usually does not need speculation about personality, medical issues, family circumstances, protected attributes or allegations that were never established. Even where a manager strongly believes a point is true, belief is not the same as a provable fact.

Legal Issues To Check Before You Sign

Before you sign a reference letter, confirm that it is truthful, fair, privacy-compliant and internally authorised. A short delay to check the wording is far safer than sending a rushed note that creates problems later.

Accuracy and misleading statements

The first legal question is simple: is the reference accurate? If a manager says an employee “always met deadlines” but the personnel file shows repeated warnings for missed deadlines, that statement may be misleading. Problems can arise from both positive and negative exaggeration.

Take extra care with language that sounds absolute. Words like “always”, “never”, “outstanding” and “completely trustworthy” can be hard to defend. Measured wording is usually safer, especially where several managers had different experiences of the employee.

Before you sign, compare the draft against:

• the employment agreement
• job descriptions
• performance reviews
• warning letters or disciplinary records
• resignation correspondence
• any settlement or exit documents

Privacy and personal information

A reference often includes personal information, so privacy issues matter. In New Zealand, businesses should think carefully about whether they have a proper basis to disclose the information and whether the disclosure is relevant to the purpose of the reference.

Do not include extra detail just because the recipient asked for it. Sensitive information often creates avoidable risk, especially if it relates to health, family circumstances, complaints, investigations, pay, or protected characteristics. Even if a manager knows these details, that does not mean they belong in a reference.

As a practical step, keep the letter limited to what a reasonable employer would expect for assessing suitability for work. If you are unsure whether a point should be disclosed, pause before sending it.

Defamation and unfairly damaging comments

Negative references are not automatically unlawful, but unsupported damaging comments can be risky. If a manager says someone was dishonest, unsafe, aggressive or incompetent, those are serious claims. If the business cannot support them, the employee may argue the statement harmed their reputation and employment prospects.

That does not mean employers must stay silent about genuine concerns. It means those concerns should be handled carefully, factually and with proper support. For example, it is usually safer to refer to documented conduct findings than to make sweeping accusations.

Negligent misstatement and reliance

The risk is not only saying something too negative. A glowing reference can also cause trouble if the next employer relies on it and later claims the business gave an unreasonably careless statement. This can be especially relevant where the role involves trust, money handling, vulnerable people, health and safety, or supervision duties.

Businesses should resist the temptation to “help someone move on” by overstating strengths or hiding serious documented concerns. A reference is not a favour if it creates foreseeable problems for the recipient or the next employer.

Consistency with exit arrangements and internal policies

Before you sign, check whether the employee left under agreed terms. Some businesses offer a standard factual reference as part of an exit discussion. If that has happened, a manager should not send a separate version that contradicts the agreed wording.

Your internal process should also cover who can give references. For many SMEs, the safest option is a simple rule that only one role, such as a founder, HR lead or nominated manager, can provide written references on behalf of the company.

Should you include a disclaimer?

A brief disclaimer can help set context, but it is not a magic shield. If the contents are false or careless, a disclaimer may not solve the problem. Still, some businesses choose to note that the letter is based on the manager’s knowledge of the employee in their role and is provided in good faith.

If you use a disclaimer, it should be clear and proportionate. It should not contradict the rest of the letter or try to excuse statements the business has not properly checked.

Written reference or verbal reference?

Written references are easier to control, but they also create a fixed record. Verbal references can feel more informal, yet they carry similar risks because the substance of what was said still matters. If your business allows verbal references, managers should follow the same rules: stick to facts, stay consistent, and avoid off-the-cuff opinions.

Many businesses use a simple approach where all external reference requests are channelled through one internal contact. That reduces the chance of inconsistent comments from different managers.

Common Mistakes With Reference Letter for Employee from Manager

The most common mistakes happen when managers treat a reference as personal rather than corporate. A reference given casually can still expose the business if it is inaccurate, excessive or inconsistent with what the company has already documented.

1. Promising a positive reference too early

This often happens during a difficult resignation, redundancy discussion or settlement conversation. A manager wants to calm the situation and says they will provide a “great reference” without checking the records. Later, the business either has to write something it cannot support or disappoint the employee and create conflict.

A better approach is to promise only that the business will consider a factual reference in line with its policy and records.

2. Letting managers freelance the wording

Founders often assume a trusted manager will know what to say. In reality, different managers have different risk tolerances, memory gaps and writing styles. One writes three lines, another writes a page of praise, and a third includes unnecessary personal details.

A standard process helps. Many SMEs use a reference template with approved fields, such as dates, role title and a short statement about key duties. If performance comments are allowed, they should be checked before being sent.

3. Including allegations instead of established facts

This is where businesses get into trouble after complaints or disciplinary issues that did not end in a clear finding. A manager may strongly suspect misconduct, but a suspicion is not the same as a concluded fact. References should not recycle unresolved allegations as though they were proven.

If there was a formal finding and it is genuinely necessary to mention it, get legal advice or a contract review on the wording before you send the letter.

4. Sharing too much personal information

Managers sometimes include material they think makes the employee sound more relatable, such as health issues, family responsibilities or reasons for leaving. Even positive intentions can create privacy problems and distract from the purpose of the letter.

Keep the content work-related. If the information does not help assess professional suitability in a fair and relevant way, it probably does not belong in the reference.

5. Writing in absolutes

Absolute statements sound confident, but they can be dangerous. If your business says an employee was “completely honest in all dealings” and later evidence suggests otherwise, that wording may be difficult to defend. Careful, measured wording usually reflects reality better.

Safer alternatives often use phrases like:

• “In my experience”
• “During the period I managed them”
• “They consistently met the expectations of the role”
• “They performed strongly in the areas of”

6. Forgetting the audience and purpose

A reference for a junior retail role will not look the same as a reference for a finance position, senior management role or job involving vulnerable clients. The more sensitive the role, the more carefully the business should think about what it says and what it leaves out.

Ask what the recipient is reasonably trying to verify. Then answer that question honestly and no more broadly than needed.

7. Keeping no internal record

If a dispute arises later, the business should be able to show what was sent and why. Keep a copy of the final letter, note who approved it, and record the date and recipient. That small administrative step can make a big difference if memories change.

A practical internal process for SMEs

If your business does not yet have a reference process, a simple one is usually enough. It can include:

• one authorised contact for all reference requests
• a standard template for factual confirmations
• a sign-off process for any performance commentary
• a rule against discussing sensitive personal information unless clearly justified
• a file note recording what was provided

This is especially useful before you hire your first worker or before your team grows to the point where former employees start seeking references regularly. Sorting out a policy early is much easier than fixing inconsistent practices later.

FAQs

Can a manager refuse to give a reference?

Often, yes. Unless the employment agreement, workplace policy or exit arrangement says otherwise, a business is not usually required to provide a written reference. It is still wise to handle requests consistently and professionally.

Should a reference letter be positive?

No. It should be accurate and fair. If the business cannot honestly provide a positive recommendation, a short factual confirmation of role and dates may be the safer option.

Can we give only dates of employment and job title?

Yes, many New Zealand businesses do exactly that. A neutral factual reference can reduce risk, especially after a difficult employment relationship or where records do not support broader praise.

Can a former employee see the reference we gave?

They may have rights to access personal information held by the business, subject to the relevant legal framework and any exceptions. Businesses should assume a written reference may later be seen by the employee and draft it accordingly.

What if another employer calls for an informal verbal reference?

Treat verbal references with the same care as written ones. Use a consistent script, stick to verified facts, and avoid spontaneous comments that go beyond what the business can support.
