How to compare TPD cover across insurers
TPD is defined cover, and the definition is the product. Whether you can get own-occupation, which occupation classes qualify, and when the wording converts to a harsher test are the three questions that decide what your policy is worth.

In short
- Own-occupation TPD pays if you cannot return to your own job. Any-occupation pays only if you cannot work in any job you are reasonably suited to. The gap is enormous.
- Own-occupation is not offered to every occupation class, and eligibility rules differ between insurers.
- Most policies convert from own-occupation to any-occupation, or to an activities-of-daily-living test, at a set age. That age differs.
- A home duties definition covers someone not in paid work, and the tests used vary widely.
- Accelerated TPD reduces your life cover when it pays; standalone does not and costs more.
- Waiting periods before a disability is treated as permanent — commonly three or six months — differ.
- TPD and income protection solve different problems and are not substitutes for one another.
What this is, plainly
TPD cover pays a lump sum if illness or injury permanently stops you working. It sounds simple. In practice it is the most definition-dependent product in the market, because “totally and permanently disabled” is not a medical fact — it is a contractual test, and insurers set that test in different places.
The most consequential difference is the occupation definition. Under own-occupation you are assessed against the job you actually did: a surgeon who loses fine motor control cannot be a surgeon, and the policy responds. Under any-occupation the same surgeon can teach or consult, so the claim fails.
Which of those you can buy depends on your occupation class, your insurer and your age at application, and it changes over the life of the policy because most wordings convert to the harsher test at a specified age.
The six things to compare
| Dimension | What to ask |
|---|---|
| Occupation definition | Is own-occupation available to me? If not, is there an intermediate definition based on duties or hours rather than any occupation at all? |
| Occupation class eligibility | Which classes qualify for own-occupation with this insurer, and how is my job classified? Class definitions are not standard between insurers. |
| Conversion age | At what age does the definition convert to any-occupation, or to an activities-of-daily-living test? Some convert at 60, some later, and some benefit types convert earlier than others. |
| Home duties definition | If I am not in paid work, what test applies? Ask for the specific list of tasks or activities and how many must be affected. |
| Standalone or accelerated | Does a TPD claim reduce my life cover? If so, can the life cover be bought back, and on what terms? |
| Waiting and assessment period | How long must the disability persist before it is assessed as permanent — three months, six months — and what evidence is required at that point? |
Why the conversion age is the sleeper issue
Most people buy TPD in their thirties or forties, when own-occupation is available and affordable. The wording then converts, often somewhere around 60 to 65, to a much harder test — either any occupation, or an activities-of-daily-living definition that requires you to be unable to perform basic functions like dressing, bathing or feeding yourself.
That is precisely the age band in which permanent disability becomes more likely. The cover people rely on most in their sixties is frequently narrower than the one they bought in their thirties, and almost nobody is told that at the point of sale. Ask for the conversion age and the post-conversion definition in writing.
Not sure what cover you actually need?
That is the question an adviser is there to answer. Tell us your situation and a licensed New Zealand adviser will compare the market and come back with a written recommendation — including where you can cut cover you do not need.
No cost to you and no obligation. General information only — not personalised financial advice.
What to watch for
These are the details that decide whether the cover does what you expected. Read them before you compare on price.
- Whether your occupation class qualifies for own-occupation with this insurer, and whether it would with another.
- The exact conversion age, and whether it differs between the TPD benefit and any TPD attached to trauma cover.
- Whether the definition requires you to be permanently unable to work, or unlikely ever to work again — the evidential bar differs.
- Whether a return to any paid work, even part-time and unrelated, defeats the claim.
- Whether the policy pays as a lump sum or in instalments, and whether any part is withheld pending review.
- Whether a TPD claim on accelerated cover permanently reduces the life sum insured your family relies on.
Where an adviser makes a difference
Every New Zealand insurer writes TPD cover to its own wording, and the words are where the money is. Two policies that look identical on price can pay very differently when it matters. Closing that gap is the entire job of an adviser.
- Own-occupation availability is occupation-class dependent and class definitions differ between insurers — an adviser knows which insurer classes your job most favourably.
- Conversion ages differ, and an adviser will show you what your cover becomes at 60 rather than only what it is today.
- Where own-occupation is unavailable, an adviser can compare intermediate definitions instead of accepting any-occupation by default.
- An adviser can price standalone against accelerated TPD and quantify what the buy-back is worth.
- TPD claims are heavily evidenced and often contested. An adviser knows what specialists need to write and when.
There are three ways to buy life cover in New Zealand, and they are not equivalent. You can buy direct from one insurer, which means you see one product range and one underwriting appetite. You can buy through your bank, which usually means a single insurer’s product sold under the bank’s brand, often with narrower definitions. Or you can go through an adviser, who quotes several insurers at once and is required to put your interests first.
The premium you pay is the same either way. Insurers build adviser commission into their pricing whether or not an adviser is involved, so going direct does not get you a discount — it just removes the person whose job is to argue your corner at application and at claim time.
- An adviser can see which insurer is currently taking your health history on standard terms, and which one will load or exclude it.
- An adviser can structure cover across two insurers if that produces a better outcome than putting everything with one.
- An adviser handles the underwriting back-and-forth, and is the person who chases the claim when a family is least able to.
- An adviser has to document why the recommendation suits you, which is a written record you can hold them to.

You decide, in your own time
There is no obligation and no cost to you. If the answer is that you already have enough cover, a good adviser will tell you that.
Frequently asked questions
What is the difference between own-occupation and any-occupation TPD?
Own-occupation assesses you against the job you actually did, so you can claim if you cannot return to that work. Any-occupation assesses you against any job you are reasonably suited to by education, training or experience, which is a much harder test to meet. The same disability can produce a paid claim under one and a declined claim under the other.
Which occupations can get own-occupation TPD in New Zealand?
It varies by insurer. Professional and white-collar classes are generally eligible; heavier manual occupations often are not, and some insurers restrict it further. Occupation class definitions are not standardised, so the same job can be classified differently at different insurers — which is one of the clearest arguments for quoting a panel rather than one company.
At what age does TPD cover change definition?
Most New Zealand wordings convert own-occupation to any-occupation, or to an activities-of-daily-living test, at a specified age somewhere in the sixties. The exact age differs between insurers and sometimes between benefit types within the same policy. Because permanent disability becomes more likely with age, this clause deserves more attention than it usually gets.
What is an activities of daily living definition?
A test that requires you to be unable to perform two or more basic functions — typically dressing, bathing, feeding, toileting and mobility — without assistance. It is a very high bar. Someone permanently unable to do any paid work may still pass all five activities and therefore fail the test, which is why a policy that converts to ADL is materially narrower than one that does not.
How much do insurers differ on the home duties TPD definition?
Substantially. It is one of the least standardised clauses in the market: the household tasks listed, how many must be affected, and the maximum sum insured available under the definition all vary. If you are insuring someone not in paid work, ask each insurer for the exact wording rather than the benefit name.
