Navigating Medical Incapacity: A Guide for NZ Employers
When a team member is facing a long term illness or severe injury, it is an incredibly stressful time for everyone involved. For employers, business demands don't stop, and managing prolonged absences is tough.
In New Zealand, terminating an employee because they cannot work due to illness or injury is legally permissible, a process known as termination for medical incapacity. However, unlike redundancy or misconduct, medical incapacity is a no-fault situation. The employee hasn’t done anything wrong, which means the legal standard for fairness and empathy is exceptionally high.
Below are the answers to the most common questions, the legal pitfalls to avoid, and the truth about your rights to an employee's medical data.
Common FAQs for Employers
1. Can I dismiss someone who is away on ACC?
Yes. There is a common myth in NZ that you cannot touch an employee’s job if they are on ACC. New Zealand employment law recognises that an employer does not have to hold a position open indefinitely if the business can no longer sustain the absence. This threshold is legally referred to as the point where an employer can "fairly cry halt". However, if the injury is work related, you have heightened obligations under the Accident Compensation Act 2001 to assist actively with vocational rehabilitation before considering dismissal.
2. How long do I have to wait before starting a medical incapacity process?
There is no hard and fast statutory timeline, but case law typically views 12 weeks of continuous absence as a benchmark where a business can reasonably begin to evaluate if the absence can be sustained long term. Keep in mind, some employment agreements contain specific medical incapacity clauses specifying a timeframe (e.g., 4 or 5 weeks) after which a review can begin.
3. What if the employee has a mountain of sick leave left?
You cannot initiate a medical termination process if the employee still has accrued sick leave available that covers their current absence. They are legally entitled to exhaust their paid sick leave entitlements to recover.
Major Pitfalls to Avoid
If an employee brings a Personal Grievance (PG) for unjustified dismissal, the Employment Relations Authority (ERA) will meticulously scrutinise both your substantive reasons and your procedural fairness.
Pitfall 1: Treating the Process Like a Disciplinary Hearing
Because the employee is absent, some managers fall into the trap of using disciplinary language. Medical incapacity is an inquiry, not a punishment. Your tone must remain supportive, consultative, and focused on gathering information rather than penalising absenteeism.
Pitfall 2: Making Medical Assumptions ("Playing Doctor")
Never guess what a sick or injured worker can or cannot do. Dismissing an employee based on your own assumptions about their prognosis, without up to date, reliable medical evidence is a fast track to losing a personal grievance case.
Pitfall 3: Failing to Consider "Reasonable Accommodation"
Before you can "cry halt," you must genuinely investigate alternatives too dismissal.
Can they work reduced or flexible hours?
Can they perform "light duties" or a modified version of their role?
Is working from home an option?
If you bypass these questions and head straight for termination, the termination will likely be deemed unjustified.
Pitfall 4: Rushing the Timeline
A legally compliant medical incapacity process takes time, often weeks or months. You must give the employee reasonable opportunities to consult their own doctors, provide feedback, and bring a support person or representative to meetings.
Do Employers Have the Right to Full Medical Access?
The Short Answer: Absolutely not.
Under the Privacy Act 2020 and the Health Information Privacy Code 2020, an individual's medical records are strictly confidential. An employer has no inherent right to a worker's full medical history, nor can you demand unrestricted access to speak directly with their General Practitioner (GP) or specialist.
What You Can Ask For:
Proof of Sickness: You can require a standard medical certificate confirming they are unfit for work.
Targeted Workplace Assessments: During an incapacity process, you can ask specific, targeted questions regarding their functional limitations and prognosis. For example: "What specific duties can the employee safely perform?" and "What is the estimated timeframe for a return to full duties?"
Independent Medical Examinations: If the employment agreement allows it, you may request that the employee see an independent occupational health physician (at the company’s expense) to get a clearer picture of their ability to work.
The Employee's Right to Refuse
An employee can legally refuse to provide detailed medical info or sign a disclosure waiver. However, doing so carries a major risk for them: if they refuse to provide information, the employer is legally allowed to make a decision based entirely on the limited information they have on hand.
Empathy and Good Faith
In New Zealand, employment relationships run on a strict duty of good faith. When managing health related absences, balance the operational realities of your business with genuine compassion for the human being going through a tough time.
Disclaimer: Employment law can be highly situational. It is strongly recommended to seek expert legal or HR advice before initiating a formal medical incapacity process.
