Trauma insurance: how critical illness cover works

Trauma cover — also called critical illness cover — pays a lump sum when you are diagnosed with one of the serious conditions listed in your policy and survive a short stand-down. It is money for living, not for dying.

In short

  • Trauma pays a lump sum on diagnosis of a listed condition, regardless of whether you can still work.
  • Cancer, heart attack and stroke account for the large majority of trauma claims.
  • Payment depends on meeting the policy’s medical definition, not on how unwell you feel.
  • Most policies apply a survival period, commonly 14 days, and a three-month stand-down for cancer and some cardiac conditions at the start of the policy.
  • Accelerated trauma reduces your life cover when it pays; standalone trauma does not, and costs more.
  • Severity-based policies pay part of the sum insured for earlier-stage conditions, which changes what a comparison actually means.
  • It fills a gap ACC does not touch: ACC covers accidents, and the conditions trauma insures are almost all illnesses.

What trauma insurance actually pays for

Trauma insurance pays you a lump sum if you are diagnosed with a condition on the list in your policy, provided the diagnosis meets the definition written there and you survive the stand-down period. There is no requirement to stop working, no requirement to be permanently impaired, and no restriction on how the money is spent.

That last point is the whole design. The costs of a serious illness are rarely the ones a household has budgeted for. Someone treated for cancer in New Zealand may have most of their treatment funded publicly and still be tens of thousands of dollars out of pocket — through lost income while they are in treatment, a partner reducing their hours to provide care, travel and accommodation for treatment in another city, drugs that Pharmac does not fund, and the mortgage that keeps falling due on the fifteenth of every month.

What people actually spend it on

  • Replacing income during treatment and recovery, for themselves and often for a partner who stops work to care for them.
  • Non-Pharmac drugs and treatments that the public system does not fund.
  • Paying down or clearing the mortgage, to reduce the monthly pressure while income is uncertain.
  • Travel and accommodation where treatment is not available locally.
  • Modifying a house, or buying help with children and housework.
  • Simply buying time — the ability to say no to work for a year without the finances collapsing.

The conditions covered, and how they are defined

New Zealand trauma policies typically list somewhere between thirty and sixty conditions. The length of the list is close to irrelevant. Three conditions — cancer, heart attack and stroke — dominate claims, and the definitions attached to those three are where a policy is won or lost.

A definition is a medical test written in contractual language. A heart attack definition may require specified troponin levels together with defined ECG changes or evidence of infarction on imaging. A cancer definition typically excludes certain early-stage and low-grade tumours, or pays them as a partial benefit. A stroke definition usually requires neurological deficit persisting for a set period, with imaging evidence.

How trauma conditions are usually grouped
CategoryTypical examplesWhat decides the claim
CancerMost malignancies past a defined stageHistological confirmation and the policy’s stage and grade exclusions
CardiacHeart attack, coronary artery bypass, angioplasty, heart valve surgeryBiomarker levels, imaging, and how many vessels are involved
NeurologicalStroke, multiple sclerosis, motor neurone disease, Parkinson’sEvidence of permanent deficit and specialist confirmation
Organ and systemicKidney failure, major organ transplant, chronic liver diseaseObjective clinical criteria, often requiring ongoing treatment
Loss of functionBlindness, deafness, loss of limbs, loss of independenceMeasured permanent loss against a stated threshold

Because the definitions are technical, insurers update them over time. Ask whether the insurer operates a wording pass-back — a promise that improvements to definitions will apply to existing policyholders. Not every insurer does, and on a policy you may hold for twenty-five years it is a meaningful difference.

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.

Accelerated, standalone and severity-based

Three structural choices determine what your trauma cover costs and what it does. They matter more than the brand on the policy.

Accelerated or standalone

Accelerated trauma is attached to life cover and draws it down. If you hold $700,000 of life cover with $200,000 of accelerated trauma and you claim the trauma benefit, you keep $500,000 of life cover. Standalone trauma is a separate sum insured that does not touch the life cover, and costs more for that reason. Accelerated with a buy-back option is the middle path many advisers use.

Severity-based or full-payment

Traditional trauma pays 100% of the sum insured when the definition is met, and nothing when it is not. Severity-based policies pay graded amounts — for example a partial payment for an early-stage cancer that would fail a traditional definition entirely, and the full amount for an advanced one. A severity-based policy can pay in more situations and pay less in some of them, which makes comparing two quotes on price alone actively misleading.

Multiple claims

Standard trauma cover ends when it pays. Some policies allow further claims for unrelated conditions, sometimes after a stand-down, sometimes with a reduced sum insured. If you are insuring against a long life with more than one serious illness in it, that provision is worth understanding before you buy.

How much trauma cover to hold

There is no equivalent of the mortgage-plus-income calculation that sizes life cover. Trauma is bought to buy time, so the sensible way to size it is to ask how long you would want to be able to stop, and what would have to be paid during that period.

  1. 1Decide how long you would want to be able to be off work — one year is a common answer, two years is safer for a serious cancer diagnosis.
  2. 2Multiply your household’s essential annual outgoings by that period.
  3. 3Add anything you would want to clear outright, most often part or all of the mortgage.
  4. 4Add a realistic allowance for treatment costs the public system does not fund, and for travel.
  5. 5Subtract what income protection would pay over the same period, and any employer sick leave.
  6. 6The remainder is the trauma gap. For many New Zealand households it lands somewhere between one and three times annual household income.

Affordability is the constraint that usually decides it. Trauma cover is expensive relative to life cover, because claiming on it is far more likely than dying young. Where money is tight, a smaller trauma sum insured held permanently beats a large one that gets cancelled in five years — and income protection usually deserves the first call on the budget.

Where an adviser makes a difference

Every New Zealand insurer writes trauma 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.

  • Cancer definitions differ most where it matters least visibly — early-stage prostate and breast disease, melanoma depth thresholds, and carcinoma in situ.
  • Heart attack definitions have moved as troponin testing has changed. Older wordings can be harder to claim on than current ones, which is why pass-back matters.
  • Some insurers include a buy-back of life cover after an accelerated trauma claim at no extra premium; others charge for it or do not offer it.
  • Children’s trauma cover is inexpensive and included by some insurers as standard — it should never be the reason to choose an insurer, but it is worth asking for.
  • Severity-based and full-payment products cannot be compared on premium alone; an adviser can map the same diagnosis across both.
  • Where a health history makes trauma cover expensive, an exclusion on one body system is often a better outcome than a decline or a whole-of-policy loading.

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.

What happens if you get in touch

We are a referral service, not an insurer. We do not quote premiums and we do not sell policies. What we do is put you in front of one licensed New Zealand adviser who can compare the market properly.

  1. 1

    You tell us what you are looking at

    The form takes about a minute. Nobody asks for your medical history on a web form — that conversation happens with the adviser, properly, and only once you have decided to proceed.

  2. 2

    An adviser calls you

    A licensed New Zealand adviser talks through your situation: who depends on you, what you owe, what you already have in place, and what you are actually worried about.

  3. 3

    They compare the market

    The adviser quotes across the major insurers, checks which of them will take your health history on the best terms, and puts the options side by side in writing.

  4. 4

    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 trauma insurance in New Zealand?

A policy that pays a lump sum if you are diagnosed with one of the serious medical conditions listed in it, usually after a short survival period. It is also sold as critical illness or living assurance cover. You do not have to stop working to claim, and the money is not tied to treatment.

What conditions does trauma insurance cover?

Typically thirty to sixty conditions, but claims are dominated by cancer, heart attack and stroke. The length of the list matters far less than the wording of the definitions for those three, and whether the policy pays partial benefits for earlier-stage conditions.

How much trauma cover should I have?

Enough to fund the time you would want to take off. Multiply your household’s essential outgoings by the period you would want to be able to stop, add debt you would clear and treatment costs you would fund privately, then subtract what income protection would pay over the same period.

Is trauma insurance the same as critical illness cover?

Yes. New Zealand insurers use trauma, critical illness and living assurance for the same product. The names are marketing; the definitions in the policy schedule are what differ.

Does trauma insurance cover accidents?

Only where the result meets a listed definition, such as major head injury, severe burns or loss of limbs. Everyday accidents are ACC’s territory. Trauma cover exists mainly because ACC does not cover illness, and illness is where the financial risk sits for most people.

Can I still work after claiming trauma insurance?

Yes. There is no work test. The claim turns on whether the diagnosis meets the policy definition, not on whether you have stopped earning. That is the clearest difference between trauma cover and both TPD and income protection.

Does trauma cover end after I claim on it?

Usually. A standard policy pays once and ends. Some policies allow further claims for unrelated conditions, and some allow you to buy back life cover reduced by an accelerated trauma claim. Check both provisions before you assume you are still covered.
