Key Takeaways
Group health insurance lets an employer offer health cover to staff under one workplace scheme. For small businesses in NZ, a group health insurance scheme can be a practical way to attract and keep good people, and the cost can be shared in different ways. This guide covers how schemes work, how employer-paid cover is taxed, and what your team needs to know.
- A group scheme covers eligible employees under one arrangement set up through the employer.
- Employers can pay all, part or none of the premium, depending on how the scheme is designed.
- Group schemes may offer simpler acceptance terms than individual policies, depending on the insurer and group size.
- If the employer takes out and pays for cover for an employee, fringe benefit tax (FBT) applies to the premiums.
- Cover usually ends when someone leaves, though some schemes offer a continuation option.
- A scheme works well when staff understand the benefit and the design is reviewed as the business changes.
What group health insurance is
A group health insurance scheme is a workplace arrangement where one insurer covers a group of employees on agreed terms. The employer sets up the scheme, decides who is eligible and chooses how much the business contributes. Staff then get health cover through work, usually for hospital and surgical treatment, with optional extras.
How a scheme differs from individual cover
With an individual policy, each person applies, is assessed on their own health history and pays a premium based on their own details. In a group scheme, terms and pricing are set for the group as a whole. Depending on the size of the group and the insurer, that can mean simpler acceptance terms and pricing that reflects the scheme rather than each individual.
Who can be covered
Most schemes cover permanent employees, and many allow partners and children to be added, sometimes at the employee's own cost. Some insurers offer schemes to quite small teams, while others set a higher minimum number of members. Minimum group sizes and participation rules vary, so it pays to compare options.
Why health insurance matters to staff
The 2026 Cultivate Workplace Benefits Report, a survey of 1,003 employed New Zealanders, found that about 27% of respondents were offered health insurance through work. The same research found 12% of workers said health insurance was the benefit most likely to attract them to a new employer, behind flexible working and an extra week of annual leave. For a small business competing with larger employers, a well-communicated health benefit can help you stand out.
A benefit people actually use
Unlike some perks, health insurance has a clear and visible benefit when someone needs treatment. Staff and their families can get non-urgent treatment for illness through the private system, alongside the public system run by Health New Zealand | Te Whatu Ora and ACC cover for accidents.
Faster treatment can mean less disruption
For a small team, one person waiting a long time for non-urgent surgery can affect everyone. Private cover can help staff get diagnosed and treated sooner, which can help them return to full duties sooner. Health insurance does not replace sick leave or income protection, but the benefit can reduce the time someone spends unwell and waiting.
How to design a group health scheme
Most schemes come down to a handful of design choices. Getting these right at the start makes the scheme easier to run and easier for staff to understand.
| Design choice | Common options | Things to consider |
|---|---|---|
| Who pays | Employer-paid, shared, or employee-paid at a group rate | Budget, tax treatment and how much uptake you want |
| Who is eligible | All staff, or defined groups such as permanent employees after a set period | Fairness, consistency and how you describe eligibility in employment agreements |
| Family members | Employee only, or partners and children added | Whether the business contributes to family cover or staff pay the extra |
| Level of cover | Hospital and surgical, with optional specialists and tests or day-to-day extras | Core hospital and surgical cover protects against the largest bills |
| Excess | Nil, or a set amount per claim or per year | A higher excess lowers the premium but increases what staff pay when claiming |
Acceptance terms
Depending on the size of the group and the insurer, group schemes may offer simpler acceptance terms than individual policies. In some cases this can mean fewer health questions or more generous treatment of existing conditions. Smaller groups may be more likely to be fully assessed. Our guide to health insurance and pre-existing conditions in NZ explains why these terms matter.
Employer-paid, shared or voluntary
An employer-paid scheme sends the strongest signal and usually gets the highest uptake. A shared scheme splits the cost, for example with the business paying for employee cover and staff paying for family members. A voluntary scheme, where staff pay their own premiums at a group rate, costs the business little but may see lower participation.
Tax and FBT on employer-paid health insurance
How the scheme is set up affects how the premiums are taxed. According to Inland Revenue, medical insurance premiums are one of the types of employer contributions that FBT can apply to.
Employer takes out and pays for the policy
If you take out and pay for an insurance policy for an employee, you must pay FBT on the premiums. If your scheme is set up this way, include FBT in your budget and your FBT returns.
Employee owns the policy and you pay the premiums
If the employee or a family member takes out the policy and the business pays the premiums, Inland Revenue treats those payments as taxable income for the employee under PAYE rather than as a fringe benefit. You do not pay FBT on these contributions.
Get tax advice for your setup
The right structure depends on your business, your payroll and your staff. Talk to your accountant about FBT, PAYE and deductibility before you choose how to set up and pay for the scheme.
What staff need to know
A group scheme is only valuable if staff understand what they have and what happens when circumstances change.
Leaving the business
Cover under a group scheme usually ends when someone leaves. Some schemes offer a continuation option that lets departing staff move to a personal policy without new health questions, provided they apply within a set time after leaving. This can be valuable for anyone who has developed a health condition while in the scheme. Make sure staff know the option exists and how to use the option before their last day.
What is and is not covered
Give staff a plain summary of the cover, the excess, any exclusions and how to make a claim. Encourage them to check with the insurer before booking treatment, as many policies require prior approval.
Communicating the benefit
A benefit only helps recruitment and retention if people know about the benefit. Mention the scheme in job ads, offer letters and onboarding, and remind staff each year what the scheme covers and how to use their cover.
Setting up and reviewing a scheme
- Decide your budget and how much the business will contribute.
- Agree who is eligible and when new staff can join.
- Choose the level of cover, the excess and whether family members can join.
- Get tax advice on FBT and PAYE for your preferred structure.
- Compare insurers and scheme terms with an adviser, including continuation options.
- Explain the scheme to staff and record the benefit consistently in employment documents.
- Review the scheme each year as your team, budget and premiums change.
Think about the long term
If health insurance becomes part of employment agreements, changing or removing the benefit later can be harder, and may need consultation or agreement with staff. Design a scheme you can sustain, and get employment advice before making changes to an existing benefit.

Frequently Asked Questions
How many staff do I need for a group health insurance scheme in NZ?
Minimum group sizes vary by insurer, and some offer schemes to quite small teams. An adviser can tell you what is available for a business your size.
Does the employer have to pay the full premium?
No. Schemes can be fully employer-paid, shared between the business and staff, or paid by staff at a group rate.
Is employer-paid health insurance subject to FBT?
If the employer takes out and pays for the policy, Inland Revenue says FBT applies to the premiums. If the employee owns the policy and the employer pays the premiums, the payments are taxed as income through PAYE instead.
What happens to health cover when an employee leaves?
Group cover usually ends when someone leaves. Some schemes offer a continuation option onto a personal policy without new health questions, if the employee applies within the set time.
Can group health insurance cover pre-existing conditions?
Sometimes. Depending on the insurer and the size of the group, schemes may offer simpler acceptance terms than individual policies, but smaller groups are often fully assessed.
