Trauma insurance pays a lump sum when you are diagnosed with a serious condition. The part people miss is that you are insured against a policy definition, not against a disease name.
In this article
Trauma insurance, also called critical illness cover, pays a lump sum when you are diagnosed with one of the conditions your policy lists and that diagnosis meets the policy's definition of it.
Both halves of that sentence matter. Policies advertise the length of their condition list, and the lists are long. In practice the great majority of claims come from a much shorter group: cancer, heart attack and stroke. Beyond those, the list is doing less work than it appears to.
The definition is where the money actually is. A policy does not pay because a specialist used a particular word. It pays because your diagnosis meets a written test: a tumour of a certain stage, a heart attack evidenced in a particular way, neurological deficit persisting for a set period. Two policies can both list the same condition and pay differently on the same diagnosis, because the wording behind the name is not the same.
This is the single reason comparing trauma policies on price and condition count is misleading. The comparison that matters is between definitions, and it is not something most people can reasonably do for themselves.
There are two ways to hold trauma cover, and the choice changes what your family is left with after a claim.
The trauma cover sits on top of your life cover. A trauma claim pays out and reduces the life cover remaining by the same amount. It is usually the cheaper option, and for many households it is a reasonable one.
The trauma cover is separate. A trauma claim does not touch your life cover, so the protection your family relies on if you die is still fully in place. It usually costs more for the same sum insured.
The trade is straightforward once it is stated plainly: accelerated buys a lower premium, standalone buys the certainty that surviving a serious illness has not quietly reduced what your family would receive later.
Two features change the shape of a trauma policy considerably, and they are worth asking about by name.
Partial or severity-based payments pay a proportion of the sum insured for an early-stage or less severe diagnosis that does not meet the full definition. Early-stage cancers and some cardiac procedures commonly sit here. A partial payment usually reduces the remaining cover by the amount paid, though not always, and the proportion paid varies by insurer and condition.
Buy-back lets you reinstate cover after a claim, commonly around 12 months later, generally without new health questions. That matters because a person who has claimed once is often uninsurable on the open market afterwards. The reinstated cover normally excludes the condition you claimed on and anything closely related to it, so it is protection against the next unrelated event, not the same one again.
Neither feature is universal, and where they exist the terms differ. They are a large part of what separates two policies that look identical on price.
Trauma and income protection are often discussed together and they answer different questions.
Income protection replaces part of your income, month by month, while illness or injury keeps you from working. Trauma pays one lump sum on diagnosis, whether or not you stop working at all. Someone can be diagnosed, treated, and keep working through it, and the trauma claim is still payable.
The lump sum tends to go where a monthly benefit cannot reach: treatment not funded publicly, travel for treatment, a partner reducing their hours, or paying down the mortgage so the household simply needs less each month. Our guide to income protection insurance in New Zealand covers the monthly side, including why ACC does not respond to illness.
Neither one replaces life cover, which answers the question of what happens to the debt if you do not survive. Our guide on what happens to your mortgage when you die sets out how the layers fit together.
Policies list the conditions they cover, and the list is long, but the great majority of claims in practice come from cancer, heart attack and stroke. What matters more than the length of the list is the definition attached to each condition: a policy does not pay because you have been told you have a heart condition, it pays because your diagnosis meets the wording set out in that policy.
Generally not. Inland Revenue's position is that amounts paid under a personal sickness or accident policy are usually excluded from taxable income, and are only likely to be taxable where the payment is calculated by reference to loss of earnings (Source: Inland Revenue). A trauma payment is a lump sum tied to a diagnosis rather than to lost income, so it does not normally fall into that category. Confirm your own position with your accountant.
Accelerated trauma sits on top of your life cover, and a trauma claim reduces the life cover left behind. It is usually cheaper. Standalone trauma is separate, so a claim does not touch your life cover. It usually costs more. The question is whether you want the cheaper premium or the certainty that a trauma claim leaves your family's life cover intact.
They solve different problems. Income protection replaces part of your income month by month while you cannot work. Trauma pays a single lump sum on diagnosis, whether or not you stop working, and it is the money that covers the things a monthly benefit does not: treatment not funded publicly, travel, a partner taking time off, or simply reducing the mortgage so the household needs less to run. Many people hold both, at different levels.
Usually yes. Most New Zealand policies apply a stand-down of around 90 days from the start of cover for certain conditions, cancer in particular, so a diagnosis in the first few months may not be claimable. Pre-existing conditions, and anything you disclosed that the insurer chose to exclude, sit outside the cover as well.
