Navigating Employee Rights When a Business is Sold
5 May 2025

When a business is sold, employers must balance their legal duty to employees with the practical realities of making a sale. The Employment Relations Act 2000 (ERA) requires employers to keep employees informed about any changes that could impact their jobs and to give them an opportunity to share their thoughts and provide feedback before decisions are finalised. However, this requirement can be challenging when a business sale is involved.


Why This Matters


Selling a business is a complex process and almost always affects employees, because their jobs with the current employer typically end when the sale is completed. The law requires employers to discuss these potential changes with employees before making final decisions. However, sharing sale details too early can be risky for business owners, because it involves sensitive commercial information.


Common Approaches


  1. After-Sale Consultation: Many businesses wait until a sale agreement is signed before discussing the impact with employees. This allows employers to protect confidential business details but does not fully meet the legal requirement for early consultation.
     
  2. Conditional Sale Agreements: Some businesses use conditional sale agreements, meaning the sale only goes through once certain conditions are met. This allows time to consult employees before the sale is finalised; although, it may not fully satisfy the ERA’s requirements.


Protecting Confidential Information


Employers are allowed to withhold certain confidential details from employees if sharing them would harm the business. However, they must have a valid reason for keeping information private. Confidential information, in this case, refers to details shared under an expectation of secrecy.


Finding the Right Balance


Balancing transparency with business interests is challenging. While employers must act in good faith by informing and consulting employees, they also need to protect the business. Exploring different approaches, such as conditional sale agreements, can help businesses navigate this tricky situation while staying as compliant as possible with employment laws.


Recent Case Law


The above issues have been addressed by the Employment Court in 2024 inBirthing Centre Limited v Matas. The Court of Appeal subsequently declined the appeal against the findings brought by the Birthing Centre Limited. The case involved the acquisition of a private birthing centre by the MidCentral District Health Board (“MDHB”). The transaction resulted in the vendor closing its centre, terminating the employment of all midwives, with the MDHB offering them new employment. The MDHB requested that the employees not be informed of the negotiations due to confidentiality reasons and the terms of the agreement were only announced after the transaction was finalised. Although the affected employees were consulted about some terms and conditions of employment with MDHB, the termination and transfer of their employment was effectively concluded by the time they were notified.


Several employees raised personal grievances for unjustified dismissal and breaches of good faith alleging they were not adequately consulted. The key focus of the arguments before the Employment Court were whether the threshold had been met allowing the vendor to withhold details of the sale until completion on the grounds that it was commercially sensitive. The Employment Court held that the vendor had failed to meet its obligations and concluded“a fair and reasonable employer could in the circumstances have considered options for exploring whether it could maintain the integrity of [its] commercial position as well as the DHB’s commercial position, while informing its employees of the proposal in a confidential way”.


The Employment Court further held that the vendor had failed to:


  • consider whether providing information to the union was viable on an embargoed basis;
  • direct employees not to share information during the consultation process;
  • include as a condition of sale that staff be consulted on a confidential basis and their view sought before the sale agreement became unconditional. 


Conclusion


It is necessary to take into account basic employee rights when selling a business. Although it may be important to protect commercially sensitive information, employers need to look at ways to ensure that employees are kept informed about potential decisions which will affect their employment. A business will need objective evidence to justify maintaining confidentiality of information, including evidence of unreasonable prejudice to their commercial position which would occur if they did share information with employees prior to finalising a sale.

Alternative Holidays Current system If the full-time employee works on a public holiday that is an OWD, they get one full alternative holiday , no matter how many hours they worked. The full-time employee must take their leave on another OWD. The full-time employee can cash their leave up after 12 months. Proposed new system The full-time employee earns alternative holiday hours , matching the number of hours they worked (or were on call and called in) on the public holiday. The full-time employee can take the hours on any day they could normally work . The full-time employee can cash their hours up at any time . Leave Payments Current system Leave payments require multiple calculations to account for variable hours and payments. Annual leave taken soon after parental or volunteer leave is paid at a lower rate . Proposed new system All leave is paid at an hourly rate , based on the lowest hourly rate payable for the day the leave is taken plus an average for piece‑rate work. Fixed allowances are paid in full during leave. Annual leave after parental or volunteer leave is paid normally . Leave Compensation Payments (Replacing “Pay as You Go”) Current system Employers and workers can agree to “Pay as You Go” (8% of gross earnings) for casual short‑term work. Proposed new system A Leave Compensation Payment (LCP) of 12.5% of a worker’s ordinary hourly rate is paid on all casual hours . Workers with standard hours also get LCP on additional hours they work, instead of accruing annual or sick leave on those hours. Fixed‑term workers earn leave from day one .

Artificial intelligence ( AI ) is no longer a futuristic idea knocking at the door of legal practice. It is already here. For lawyers, the challenge is not simply to use AI, but to use it responsibly, carefully, and in a way that genuinely benefits clients. In broad terms, AI can process, organise, and generate information at speed. In legal practice, that can be valuable. AI can assist with first drafts of correspondence, summarising lengthy emails or documents, preparing chronologies, comparing versions of agreements, identifying recurring clauses, and improving the clarity of client updates. For example, a lawyer reviewing a large chain of correspondence may use AI to prepare an initial summary of key dates and issues. A commercial lawyer may use it to highlight changes between document versions. A litigator may use it to organise background material before preparing advice. Used properly, AI can reduce time spent on repetitive tasks and allow lawyers to focus on judgment, strategy, and client service. However, AI is not a lawyer in disguise. It can produce inaccurate material, miss context, reflect bias, orgenerate confident-sounding answers that are wrong. In legal practice, there are also serious risks around privacy, confidentiality, professional responsibility, and over-reliance. AI may assist with the heavy lifting, but lawyers must still hold the pen. At Glaister Keegan Lawyers, our AI journey is guided by a balance of innovation and discipline. The firm has developed an artificial intelligence policy to guide the responsible, ethical, and practical use of AI. The policy includes strict requirements relating to privacy, confidentiality, competence, professional responsibility, and verification. Client confidentiality remains fundamental. The firm will take a careful and measured approach to the use of AI tools. Any AI tool used by the firm must provide appropriate safeguards for privacy, confidentiality and information security. This means adopting tools and processes that support the secure handling of client information, controlled access, and responsible use, while maintaining the standards of care, confidentiality, and professionalism our clients expect. Our staff are receiving appropriate guidance and training on the responsible use of AI tools, including their limitations and the circumstances in which they may be used. All AI-generated output will be checked by our staff before being used or relied upon. In short, we are embracing AI, but with the guardrails firmly in place. For us, AI is not about replacing people with prompts. It is about equipping our lawyers to work more efficiently, think more clearly, and continue delivering practical, trusted legal advice in a changing world.  About the Author - Adrian Sharma is a qualified Fiji lawyer and our AML Compliance Officer. As he works towards requalifying in New Zealand, he continues to contribute his strong legal and compliance knowledge, with a keen interest in how emerging technologies such as AI are shaping the future of business and professional services.
