Calculate the right level of trauma insurance (also called critical illness cover) for your household and estimate the premium. Trauma cover pays a tax-free lump sum on diagnosis of a defined serious condition: cancer, heart attack, stroke, multiple sclerosis, major organ transplant, and many others.
Cancer alone accounts for around 59% of NZ trauma claims (AIA 2024 data), with heart conditions at 16% and neurological conditions at 11%. ACC does not cover illness, so trauma cover fills a critical gap for conditions that income protection may pay slowly or not cover in full.
This calculator models your cover needs based on debts to clear, recovery time costs, medical gap expenses, and household commitments, then estimates the annual and monthly premium based on your age, gender, smoker status, and choice between standalone and accelerated cover structures. Uses current rates from AIA, Partners Life, Chubb Life, Asteron Life, and Fidelity Life as at April 2026.
AIA NZ paid $139 million in trauma claims in 2024. The breakdown shows where your cover is most likely to be needed:
None of these conditions are covered by ACC. The NZ Cancer Registry reports 25,700 cancer diagnoses per year (2015-2019 average), projected to rise to 45,100 per year by 2040-2044.
Premium estimates are indicative only, based on market research across AIA, Partners Life, Chubb Life, Fidelity Life, and Asteron Life for standalone stepped trauma cover. Actual premiums depend on full medical underwriting, occupation, hobbies, family medical history, and any multi-policy discounts. Level premiums start 40-60% higher but do not increase with age. Accelerated trauma (linked to life cover) is typically 10-20% cheaper than standalone.
Trauma insurance (also called critical illness cover) pays a tax-free lump sum if you are diagnosed with a defined serious medical condition. Unlike health insurance which reimburses treatment costs, trauma pays cash you can use however you want: mortgage payments during recovery, private or overseas treatment, home modifications, paying off debt, topping up income, or covering childcare while you recover.
Most NZ trauma policies cover between 35 and 50+ medical conditions. Commonly covered conditions include:
Understanding what claims actually get paid helps calibrate cover amounts. AIA NZ (the largest NZ life insurer) paid $139 million in trauma claims in 2024:
| Condition Type | % of Claims | Typical Average Claim |
|---|---|---|
| Cancer | 59% | $150,000 to $300,000 |
| Cardiovascular (heart attack, bypass) | 16% | $100,000 to $250,000 |
| Neurological (MS, Parkinson's, stroke) | 11% | $150,000 to $400,000 |
| Musculoskeletal | 8% | Varies widely |
| Other (burns, organ failure, sight loss) | 6% | Varies widely |

| Feature | Standalone Trauma | Accelerated Trauma |
|---|---|---|
| Sum insured | Separate from life cover | Shared with life cover |
| Impact of trauma claim on life cover | No impact | Life cover reduces by trauma claim amount |
| Typical premium | Baseline | 10 to 20% cheaper |
| Best for | Families needing full protection against both illness and death | Budget-conscious, single people, or when life cover and trauma can reasonably share |
| Buy-back option | Not needed | Usually available: restores life cover after trauma claim without re-underwriting |
Trauma insurance has the same premium structure choice as life insurance:
For personal trauma insurance:
This differs from income protection (premiums deductible, benefits taxable) and aligns with life insurance tax treatment. For business-owned trauma cover used for key-person protection, different tax rules may apply and depend on specific circumstances. Consult your accountant.
Most NZ trauma policies impose a 3-month stand-down period on certain conditions after policy inception. A claim for one of these conditions within 90 days of the policy starting is usually declined. Commonly affected conditions include:
The rationale is to prevent people from buying cover after diagnosis but before formal confirmation. Buy trauma cover well before you think you might need it: delays can be costly.
Most NZ insurers offer optional or built-in children's trauma cover, typically:
Children's trauma cover provides a lump sum if a child is diagnosed with a covered condition such as childhood cancer, meningitis with permanent effects, severe burns, congenital heart disease requiring surgery, or major brain injury.
Trauma insurance is a life insurance product regulated in NZ by the Financial Markets Authority (FMA) under the Financial Markets Conduct Act 2013 and the Financial Advice Provider regime. Disputes can be escalated to the Insurance and Financial Services Ombudsman (IFSO). The duty of utmost good faith applies: non-disclosure of material health facts can void a claim. Always fully disclose medical history at application, even if it means higher premiums or loadings.
