The short answer
Trauma insurance (also sold as critical illness cover) pays a tax-free lump sum when you are diagnosed with one of a defined list of serious conditions — cancer at a specified severity, heart attack, stroke, major organ failure, multiple sclerosis and typically 30 to 50 others.
You do not need to be unable to work and you can spend it on anything. That flexibility is the entire product.

What people actually spend it on
The brochures talk about medical costs. In practice, in New Zealand, the payout usually goes on the things insurance does not otherwise touch:
- A partner dropping to part-time or stopping work to be a carer
- Clearing or reducing the mortgage so the household's fixed costs shrink
- Treatment or drugs outside the funded list, or treatment overseas
- Travel and accommodation for treatment if you do not live near a major centre
- Home or vehicle modifications after a stroke
- Simply buying time — a year of not making financial decisions under pressure
Standalone vs accelerated — read this before you buy
Accelerated trauma is attached to a life policy: a trauma claim reduces your life cover by the amount paid. It is cheaper, and for many people it is fine — if you claim on trauma and survive, you can often reinstate the life cover later, sometimes automatically after 12 months.
Standalone trauma sits on its own and does not touch your life cover. It costs more.
The mistake is not choosing one or the other. The mistake is not knowing which you bought.
It pays when you are diagnosed — not when you die, and not when you stop working.
The definitions are the product
Every trauma policy pays "on cancer". They do not all pay on the same cancer. Policies define severity thresholds — early-stage and in-situ cancers are often paid at a reduced partial benefit or not at all; heart attacks require specified troponin levels or ECG changes; strokes require evidence of permanent deficit.
Two policies at the same price can behave completely differently at claim time, and the difference is buried in definitions no comparison table shows. This is the single strongest argument for having someone who reads wordings for a living involved in the decision.
The honest case against
Trauma cover is the product most likely to be over-sold, and it deserves a fair criticism: it pays on a list. You can be seriously, expensively unwell in a way that ruins your finances and still not meet a listed definition. Income protection pays on your inability to work regardless of what caused it, which is a broader trigger.
If budget forces a single choice, income protection is usually the more complete cover. Trauma earns its place as the thing that handles the first twelve months — the shock, the lump costs, the partner who stops working — while income protection handles the long middle. Full comparison →
How much do people take?
There is no formula as clean as life cover. A common approach is to size it to twelve to twenty-four months of household outgoings, plus any specific known cost (a mortgage tranche you would want gone, or a drug benefit gap). Smaller amounts of trauma are far more common — and more affordable — than the headline sums people imagine.
Common follow-up questions
Is trauma insurance worth it in New Zealand?
It depends on what else you hold. If you have no income protection, trauma is a partial substitute that pays quickly but on a narrower trigger. If you already have income protection, trauma covers the lump costs income protection does not. If you have neither and can only afford one, most advisers would start with income protection — though the right answer genuinely differs by household.
Can I buy trauma cover on its own?
Yes — that is standalone trauma. It costs more than accelerated cover attached to a life policy, but it does not erode your life sum insured when it pays.
Does trauma cover children?
Many policies offer a child's trauma benefit, usually a modest sum (often $25,000–$50,000) covering a defined set of childhood conditions. It is inexpensive. What it really buys is the ability for a parent to stop working without financial consequence during a child's illness.
If I claim, does the policy end?
Usually the cover reduces by the amount paid, and on accelerated policies your life cover reduces too. Some policies allow reinstatement of the trauma cover after a period, sometimes excluding the condition already claimed on. Worth checking — it is the difference between a one-shot policy and ongoing protection.
