Restraint Of Trade

HR Policies

26 June 2025 (Last updated 3 Dec 2025)

Share on:

Many employers have information, trade secrets, and processes that enable them to be competitive in their field. Protecting this information is often vital to the success of their business. A restraint of trade clause protects employers from having their business affected by an employee trying to share sensitive information or processes with a similar business.

There are rules in place to ensure a restraint of trade clause is reasonable and does not affect an employee’s ability to find a new job.

Due to the complex nature of a restraint clause, it is recommended to seek independent legal advice before trying to enforce a restraint clause against an employee who joins a competitor or starts a competing business.

Types of restraint trade clauses

Below are the two most common types of restraint clauses in NZ:

  • Non-Competition: prevents a former employee from working for a company that conducts work that is similar to their former employer’s business.
  • Non-Solicitation: allows a former employee to work for a company in a similar field or industry. However, they are not allowed to contact clients from their former employer about the new business.

Each business has their own specific limitations and restrictions. For example, a restraint clause may prevent an employee from working a secondary job in a business similar to their current job. Alternatively, a restraint clause may state the employee is unable to work with former clients for a certain period of time.

Things to include in a restraint clause

A restraint of trade clause can only be enforced if the conditions are reasonable and the employer has a specific business interest to protect. Fear of competition is not a reasonable excuse to enforce a restraint of trade clause. It is also unreasonable to enforce a clause that makes it hard for the employee to find employment in their field of work.

Business interests that can be reasonably protected include:

  • specialised knowledge about processes, methods and techniques
  • confidential information
  • strong connections with existing customers and clients
  • trade connections

Most restraint clauses last for a few months or can be up to 12 months. It is not standard for a restraint clause in NZ to last longer than 12 months, but there may be an exception under special circumstances.

These clauses can also place limits on who and where a former employee can work. However, the conditions must be reasonable in relation to the geographical area and population. For example, a restraint clause may prevent former employees working a certain distance from their former employer or working with a certain group of people.

Challenging a restraint clause

An employee who believes they are subject to an unreasonable restraint clause may escalate this to the Employment Relations Authority (ERA). Depending on the circumstances, the ERA may work with both parties to develop more reasonable terms.

Breaching a restraint clause

There are ways for employers to stop business activity that breaches a restraint clause. They may be able to ask the ERA to step in and inform the employee to stop the activity. The ERA may also impose penalties and recover lost business or the cost of damage as a result of the employee’s breach.

Using confidential information

Not all skills and knowledge gained from an employee are considered confidential. This will depend on the information and how it has been applied in the employee’s new position.

In each industry, there is the potential for certain processes, knowledge, and trade secrets to be considered the sole property of an employer. Whether or not information is the confidential property of an employer depends on several factors:

  • is the information a trade secret that relates to the creation of a carefully guarded product, recipe, or the way a service is offered?
  • is the information highly sensitive to the business or confidential?
  • did the employer make it clear to the employee that the information was highly sensitive or confidential?
  • was the information gained directly from the employer, or did it come from another source?

If the employee is using a general skill learned from a former employer that is common knowledge in the industry, this would not be considered a breach of clause. However, if the skill or technique was specific to processes performed by their former employer, the court may consider the information to be confidential.

To avoid potential confusion and later conflict, employers should make it clear to employees whether or not the skills, techniques or information they learn are confidential or not. Some employers add a confidentiality clause to employment agreements to protect their business. This clause can help to explain what information is considered confidential.

If you include a confidentiality clause, when your employee leaves remind them that the confidentiality clause continues after they have stopped working for you.

Steps you can take to protect IP

There are steps that employers can take to protect their intellectual property and ensure your information remains secure.

  • Limit access to any customer database and change passwords regularly

  • Don't put any confidential information on public websites

  • There is copyright in software code and database structures and interfaces. Ensure ownership of all forms of copyright is clear around your app or software code

  • Check your sales agreement to ensure your vendors and suppliers are legitimate

  • Make sure all employees and third parties sign relevant agreements and documents

  • Trademark your business or trading name, logo, and advertising with IPONZ

Email usage policy

While email has been around for years, it is still a mode of communication that involves a lot of overseeing and supervision. It’s tricky nature and lack of tone can make it an easy way for things to get lost in translation. It is hard to imagine running a business without email because it is such a convenient, flexible and immediate tool. But the fact it is so easy to send an email can result in misuse or abuse. A carelessly phrased email forwarded to lots of recipients can quickly damage your reputation or break confidentiality, even when unintended. In this best practice guide for employers, we explain email usage within the workplace and recommend a standard email usage policy that you can implement immediately. Please note that the information is general and does not constitute advice. If you need help with policies, consult an employment relations professional. Email usage in the workplace There are many risks involved with email usage. Having a company wide policy for email usage and communication can protect you and your employees from potential risks. Your employees may send emails without considering the risks of confidentiality or even security. Without a clear written and established company policy, you cannot manage security and safeguard your business. As an employer, you are liable for the acts and omissions of your employees. Drafting an email usage policy When you draft your email policy, it should keep certain factors in mind: Decide the extent to which employees can use the Internet and email for personal purposes. You should set out the consequences for not following the policy, including disciplinary action and summary dismissal. The use of email and internet should be consistent with employee responsibilities and should comply with all other rules and procedures. Avoid permitting activities which might be illegal, offensive, or likely to have negative repercussions. Depending on the business you are in, a higher level of security could be useful on the email. The email usage policy should also mention styles of communication for outside work hours or outside working days. General email usage policy requirements The policy should be made available to all staff and stored in the company internal communication network, where it can be accessed anytime. Be very clear and explicit as to what is considered forbidden. Clearly set out what information gets recorded, logged, and who has access to the information. Mention why the improper use of email can be risky and that it may pose a threat to system security and the legal liability of the organisation. Outline in plain language how the company will monitor staff compliance with company rules on acceptable use of email and browsing. The policy should be regularly reviewed in accordance with the development of the internet and information technology. Monitoring email usage There are currently no laws prescribing the prohibition of monitoring an employee’s emails or Internet usage. However, there is controversy about the grey area of ‘telecommunications’ and if it includes emails and internet. While many companies monitor email usage, the key is it to do with caution and respect: Be open about monitoring the communication channels. Your employees have a right to know that their email and internet use is monitoring. Limit personal use and set restrictions clearly. Do not intrude on the privacy of the employee and provide a mechanism for employees to delete email from the system. Any personal information that is found that concerns employees must be used fairly. Establish a business purpose for monitoring (working time is used productively or checking if they have logged in). Do not monitor websites, viewed content unless the business purpose cannot be achieved by recording time spent on the Internet. Monitoring should be limited to an automated process. You should not monitor the content of the emails unless the traffic record alone is not sufficient. If you are using the results of the monitoring, give the employee an opportunity to explain the results. Disciplinary action for improper email usage An employer may dismiss an employee for improper email usage or misuse of workplace internet resources provided the employer: Clearly demonstrates the use was an unauthorised use as defined by the email usage policy or electronic communications policy. Investigates the employee in accordance with any workplace disciplinary policy and workplace relations law. Gives the employee an opportunity to respond to the allegations. Implement effective policies with Peninsula The changing world of telecommunications means it can be tricky to ensure the safety of your employees and your business.
