Employer and Group Health Insurance in NZ (2026): What Happens When You Leave the Job

Work health cover usually stops when the job stops. Here is how NZ group health insurance works, what a continuity option does, and why your pre-existing conditions matter most on the way out.

A lot of New Zealanders get their first health insurance through work, often without thinking much about it. You join an employer, you are added to the group scheme, and a useful benefit quietly sits in the background. The catch is that this cover is usually tied to the job. When the job ends — whether you resign, retire or are made redundant — the cover can end with it, and the moment you leave is often the worst time to be starting from scratch with a new insurer.

This article explains how group health schemes work in New Zealand, why they are usually easier to get on than a personal policy, what actually happens to your cover when you leave, and the one feature — the continuity option — that can protect everything you have built up. It also covers the catch that catches most people: the conditions you developed while on the group scheme.

TL;DR: Group health cover is usually easy to join because there is no individual underwriting ⁷, but it generally ends when your job does. Many schemes let you convert to a personal policy on the same terms without new health questions — but only if you act inside a short continuity window, commonly around 45–60 days after leaving ⁸. Miss it and standard underwriting applies, which can exclude conditions you developed on the scheme.

How does employer and group health insurance work in NZ?

A group (or "workplace") health scheme is a single arrangement an employer sets up to cover its staff, rather than each person buying their own policy. Health insurance is the second most common type of cover New Zealanders hold after life insurance, and roughly 37% of the population — around 1.45 million people — now have some form of it ⁶. A good share of that is arranged through work.

Health insurance in New Zealand is mostly about access to private treatment: skipping public surgical waitlists for non-urgent operations, seeing specialists faster, and getting diagnostics done sooner. The market is dominated by a few names. Southern Cross Health Society is the largest health insurer, covering more than 951,000 members as at 30 June 2025 — about one in five New Zealanders — and is also the largest provider of workplace schemes, insuring around 3,600 businesses ¹². Other insurers, including nib, AIA and Accuro, also write group cover, and each sets its own terms.

The key thing to understand is the structure. On a group scheme:

• The employer holds the master policy and the staff are insured members under it.
• New staff are usually added automatically when they join and meet the eligibility rules (often permanent employees working a minimum number of hours).
• The employer often pays some or all of the premium, sometimes with staff topping up to add family members.

Because the policy belongs to the employer, your membership is a benefit of employment — not something you own outright. That single fact drives almost everything that follows.

Why is group cover usually cheaper and easier to get on?

Two features make group schemes attractive, and both come from the same place: the insurer is pricing and accepting a whole group rather than each individual.

No individual underwriting on the way in. This is the big one. A personal health policy is medically underwritten — you complete health questions, and the insurer can exclude pre-existing conditions or load the premium based on your history. Most group schemes accept staff on automatic-acceptance terms with no individual underwriting — no health forms, no medical exams ⁷. That means someone can be covered immediately even for a pre-existing chronic condition such as diabetes, cancer or heart disease that would normally be excluded or heavily restricted on a personally underwritten policy ⁷. For anyone with a health history, this is genuinely valuable cover they might not be able to buy on their own.

A single, often lower cost. Because the group is priced as a whole, the cost per head can be lower than each person buying comparable individual cover, and the admin sits in one place.

It is worth being clear-eyed about the limits, though. Automatic acceptance usually applies up to a set level of cover; higher amounts or certain benefits can still require underwriting. Premiums are not fixed either — group rates can rise at renewal as the membership ages or claims grow, the same way personal premiums do. And whether any given claim is paid still depends on the scheme's terms, stand-down periods and exclusions. Easy to join is not the same as unlimited.

What happens to your cover when you leave or are made redundant?

This is the part many people only discover at the wrong moment. Because the cover is attached to your employment, leaving the job generally ends your membership of the group scheme. That applies whether you resign, retire, or are made redundant. Redundancy can feel especially harsh here, because you lose both the income and the cover at the same time.

What does not happen automatically is any kind of free continuation. Your cover does not quietly follow you to your next job, and it does not convert into a personal policy on its own. Once your employment ends, there is usually a short period before the cover lapses, and what you do in that window matters a great deal.

The risk is sharpest for anyone who used the scheme. If you joined the group with a pre-existing condition that was accepted without underwriting, or if you developed a condition while you were a member, that history is now part of your medical record. Walk away and apply fresh to a personal policy later, and that condition will be assessed under full underwriting — which can mean an exclusion, a loading, or in some cases a decline ⁷. The protection you had on the group scheme does not carry over by default.

There is one bright spot built into most schemes to deal with exactly this problem: the continuity option.

What is a continuity option and why does it matter?

A continuity option (sometimes called a continuation or transfer option) is a right, written into many group schemes, to convert your group membership into your own personal policy without going through new underwriting — keeping the acceptance terms you already had, including for conditions that would otherwise be excluded ⁸.

In plain terms: it lets you take your cover with you and keep the conditions you developed on the scheme covered, rather than starting again from a blank application. For someone who has been on a group scheme for years, or who has had a health event during that time, this can be the difference between continuous cover and being effectively uninsurable on the open market.

The reason it matters so much is the catch in the next section: without it, the conditions you developed on the group scheme are exactly the ones a new personal policy is likely to exclude.

But — and this is the part people miss — the continuity option is time-limited and conditional. Based on typical NZ provider terms, the window to exercise it is commonly around 45 to 60 days (roughly two months) from when your employment ends ⁸. After that window closes, you generally lose the right to convert without underwriting, and standard health questions apply. The option is also usually only available while no claim is currently in progress and while you remain resident in New Zealand ⁸.

The exact period and conditions are set in each insurer's policy wording and vary between schemes, so the precise number of days is not universal. That is precisely why you should not guess it — you need to confirm the specific window for your scheme, in writing, before it runs out.

Will conditions you developed on the group scheme be excluded later?

This is the question that should drive your decision, so it is worth being direct about it.

If you exercise the continuity option in time, the conditions you had accepted on the group scheme generally carry across to your new personal policy on the same terms, without fresh underwriting ⁸. The cover you built up is preserved.

If you let the window close and apply for a personal policy later as a new applicant, those same conditions are assessed under standard underwriting. A condition that the group scheme covered automatically — say a heart condition, a back problem, or a cancer history — can then be permanently excluded, loaded with a higher premium, or occasionally declined ⁷. In other words, the very conditions that make cover most valuable are the ones most at risk if you do nothing.

There are two finer points worth knowing. First, even a continuity option is not a blanket guarantee for everything — there can still be stand-downs on the new personal policy, and acute care and other excluded categories work the same way they would on any health plan. Second, the rules differ by insurer and by plan, so two people leaving two different employers can face quite different outcomes.

Group scheme vs your own personal policy: the real trade-offs

It is tempting to assume the group scheme is simply the better deal because it is cheaper and easier to get on. While you are employed, that is often true. But the two products solve different problems, and the differences matter most at the point you leave.

Read across that table and the pattern is clear. The group scheme wins on ease and cost while you are in the job. The personal policy wins on portability and certainty — it is yours, it cannot be removed by a change of employer, and it locks in the terms you were accepted on. For many people the sensible answer is not "one or the other" but understanding how to move from the first to the second without losing ground, which is exactly what the continuity option is for.

How to protect yourself before you leave a job

If you have health cover through work and a job change is on the horizon — including a possible redundancy — a few steps taken early can protect cover that is very hard to replace later.

1. Find out what you actually have. Ask your employer or HR for the scheme details and the policy wording. Confirm the insurer, the level of cover, and whether a continuity option exists.

2. Pin down the continuity window in writing. This is the single most important number. Confirm exactly how many days you have from your last day of employment to convert without underwriting, since it varies by scheme ⁸. Do not rely on a rough estimate.

3. Check the conditions on the option. Most require that no claim is currently in progress and that you remain in New Zealand ⁸. If you have a claim underway or are moving overseas, get advice before you assume anything.

4. Act before, not after, your last day where you can. The window is short, and admin around leaving a job is busy. Starting the conversion early avoids a lapse that could trigger fresh underwriting.

5. Weigh continuity against a fresh personal policy. Sometimes converting is clearly best — especially if you developed conditions on the scheme. Sometimes a younger, healthy person can get competitive standard cover instead. Comparing across insurers is how you tell which applies to you.

6. If you run a business, think about the team too. Owners arranging cover for staff face the same continuity questions in reverse. Our guide to business protection covers where group cover fits alongside personal and key-person arrangements.

The common thread is timing. Almost everything about leaving a job with work health cover comes down to acting inside a window most people do not know exists.

Frequently asked questions

Does my work health insurance stop when I leave the job?

Usually, yes. Group health cover is tied to your employment, so resigning, retiring or being made redundant generally ends your membership of the scheme. It does not automatically transfer to a new employer or convert to a personal policy on its own. Most schemes do offer a continuity option to convert without new underwriting, but only if you act inside a short, time-limited window ⁸.

What is a continuity option on a group health scheme?

It is a right written into many group schemes to convert your group membership into your own personal policy without going through new health underwriting, keeping the acceptance terms you already had ⁸. It is the main way to take your cover — and any conditions you developed on the scheme — with you when you leave a job.

How long do I have to use the continuity option?

It is time-limited, commonly around 45 to 60 days (roughly two months) from when your employment ends, based on typical NZ provider terms ⁸. The exact period is set in each insurer's policy wording and varies between schemes, so confirm your own scheme's window in writing rather than relying on a general figure.

Will the conditions I developed at work be covered on a new policy?

If you exercise the continuity option in time, the conditions accepted on the group scheme generally carry across without new underwriting ⁸. If you let the window close and apply later as a new applicant, those conditions are assessed under standard underwriting and can be excluded, loaded or sometimes declined ⁷. That is the central risk of doing nothing.

Is group cover better than my own personal policy?

They solve different problems. Group cover is usually cheaper and easier to join because there is no individual underwriting ⁷, which suits you while employed. A personal policy is portable and stays with you regardless of your job. Whether a claim is paid under either depends on the policy terms, stand-downs and exclusions — always read the wording.

What should I do first if I'm leaving a job with health cover?

Get the scheme's policy wording and confirm two things: whether a continuity option exists, and exactly how many days you have to use it. Then weigh converting against a fresh personal policy, ideally before your last day, since the window is short and standard underwriting applies once it closes ⁸.
