ACC vs income protection: the gap nobody explains
New Zealanders are told from childhood that ACC has them covered. It does — for injury caused by accident. It does not cover cancer, heart disease, mental illness or most degenerative conditions. That single distinction is the whole argument for income protection.

In short
- ACC covers personal injury caused by accident. It is not a general sickness scheme.
- Illness sits outside ACC almost entirely — cancer, heart disease, mental illness, most degenerative conditions.
- ACC weekly compensation is generally around 80% of pre-injury earnings, subject to statutory caps and rules.
- It stops when you can return to work, or when entitlement otherwise ends. It is not a long-term income.
- Income protection responds to illness as well as injury, which is exactly the space ACC leaves open.
- Most income protection policies offset ACC payments, so the two are designed to work together rather than double up.
- The self-employed and contractors carry the most exposure, because they have no sick leave behind them either.
What ACC actually covers
New Zealand’s Accident Compensation scheme is unusual internationally and genuinely good at what it does. In exchange for giving up the right to sue for personal injury, everyone in New Zealand gets cover for personal injury caused by accident — treatment costs, rehabilitation, and where the injury stops you working, weekly compensation.
The word doing the work in that sentence is “injury”. ACC is an accident scheme, not a health scheme. It responds when something happens to you — a fall, a crash, a strain with an identifiable cause, a treatment injury. It does not respond because you became unwell.
That is not a gap someone forgot to close. It is the deliberate design of the legislation, and it has been the design since the scheme began. But it is not what most New Zealanders believe. The widespread assumption that “ACC will cover me if I can’t work” is true for one category of misfortune and false for the larger one.
What sits outside it
Consider the conditions that actually stop New Zealanders working for long periods. Cancer. Heart disease. Stroke. Multiple sclerosis. Depression and other mental health conditions. Chronic pain of gradual onset. Degenerative joint and spine conditions. Autoimmune disease. Almost none of these is an accident, and almost none of them is covered by ACC.
- Cancer of any kind, unless it arises from a specifically covered work-related exposure.
- Heart attack and stroke, other than in narrow circumstances connected to a covered injury or covered work-related cause.
- Mental illness, unless it is a covered mental injury arising from a physical injury or from specified circumstances.
- Most degenerative conditions — osteoarthritis, disc degeneration, wear that has built up over years.
- Illness of gradual onset generally, outside the specific occupational disease provisions.
- Ordinary sickness of every kind, however disabling.
For a household, the practical question is simple: if the income stopped for two years, would the reason more likely be an accident or an illness? For most people, over a working life, illness is the larger risk. ACC does not touch it.

How ACC weekly compensation works
Where ACC does accept a claim and you cannot work, weekly compensation is generally payable at around 80% of your pre-injury earnings, calculated under statutory rules and subject to a maximum set by legislation. There is an initial period at the start of an injury where an employer’s obligations and ACC’s begin at different points, and the calculation is different again for the self-employed and for people whose earnings are irregular.
- The rate is generally around 80% of pre-injury earnings, not 100%.
- There is a maximum insurable earnings level set by legislation, so higher earners are capped.
- Payments are taxed.
- Entitlement continues while you are unable to work because of the covered injury, and it stops when you can work again.
- ACC actively manages return to work, including rehabilitation and graduated return.
- For the self-employed, the calculation is based on past earnings unless a CoverPlus Extra agreement is in place.
Do not treat any figure you read online as current. Rates, caps, thresholds and the earnings calculation rules are set by legislation and regulation and are reviewed periodically. Check acc.co.nz for the numbers that apply now.
The two side by side
| ACC | Income protection | |
|---|---|---|
| Covers injury by accident | Yes | Yes |
| Covers illness | Generally no | Yes |
| Covers mental illness | Only in limited covered circumstances | Depends on the policy and any exclusions |
| Covers degenerative conditions | Generally no | Usually yes, subject to underwriting |
| Rate of payment | Generally around 80% of pre-injury earnings, capped | Chosen at application, commonly up to around 75% of income |
| How long it lasts | While the covered incapacity continues | To the benefit period chosen — two years, five years, or to age 65 |
| Who pays for it | Levies | Premiums you choose to pay |
| Certainty for the self-employed | Based on past earnings unless CoverPlus Extra is agreed | Agreed value structures can fix the amount in advance |
General description of how the two operate. ACC entitlements are set by legislation and change — check acc.co.nz for current figures.
They are not competitors. ACC is compulsory and you have it whether you want it or not. Income protection is the layer that covers the risk ACC was never designed to carry, and most policies are built on that assumption.
How the two interact on a claim
Most New Zealand income protection policies offset ACC weekly compensation against the benefit they pay. If ACC is paying you, the insurer generally reduces its payment so that the combined amount is the benefit you insured, not the two added together. You are not paying twice for the same money, and you cannot claim twice for it either.
That has two consequences worth understanding when you set cover up:
- 1Do not buy income protection expecting it to stack on top of ACC for an accident. For injury claims, income protection is topping up rather than doubling.
- 2Do buy it for illness, where ACC pays nothing and the policy is carrying the whole risk on its own.
- 3Read the offset clause, because what is offset varies — ACC, employer payments, other insurance, and sometimes other income.
- 4Tell both ACC and your insurer about the other claim. Undisclosed parallel payments lead to clawbacks later.
Who is most exposed
Everybody is exposed to the illness gap. Some people are exposed twice over.
- The self-employed and contractors, who have no employer sick leave, no redundancy protection, and whose ACC weekly compensation is calculated from past earnings unless CoverPlus Extra is in place.
- People with variable or newly established income, where a past-earnings calculation understates what they actually earn now.
- Sole income earners in a household, where there is no second income to fall back on.
- People with a large mortgage and a small emergency fund, which is most first-home buyers.
- Older workers, for whom degenerative conditions become more likely and are largely outside ACC.
- Anyone whose employer sick leave entitlement is measured in days rather than months, which is most employees.
The uncomfortable version of this: the New Zealander most likely to say “I’m covered, we have ACC” is often the one with the least protection against the risk that is actually most likely to stop them earning.
Where an adviser makes a difference
Every New Zealand insurer writes income protection 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.
- An adviser will show you what your ACC position actually is, including how weekly compensation would be calculated on your particular earnings.
- For the self-employed they will raise CoverPlus Extra alongside private cover, because the two solve different halves of the problem.
- They read the offset clause with you before you buy, not after a claim.
- They can structure waiting periods so that private cover starts where sick leave and any ACC entitlement end.
- They know which insurers handle the injury-or-degeneration grey zone more sensibly than others.
- At claim time they can run an income protection claim alongside an ACC claim so offsets are handled correctly rather than clawed back.
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.

Frequently asked questions
Does ACC cover illness in New Zealand?
Generally no. ACC covers personal injury caused by accident, along with treatment injury and certain specified work-related conditions. Ordinary illness — cancer, heart disease, mental illness, degenerative conditions — sits outside the scheme. That is the scheme’s design rather than an oversight.
If I have ACC, do I still need income protection?
For most working New Zealanders, yes. ACC covers one category of risk and income protection covers the much larger one. If your income stopped for two years, illness is statistically the more likely cause over a working life, and ACC would pay nothing towards it.
How much does ACC pay if I cannot work?
Weekly compensation is generally around 80% of pre-injury earnings, calculated under statutory rules and subject to a maximum set by legislation. Payments are taxed and stop when you can return to work. Because the rates, caps and calculation rules change, check acc.co.nz for the figures that apply now.
Will my income protection pay on top of ACC?
Usually not. Most New Zealand policies offset ACC weekly compensation against the benefit, so the combined amount is the benefit you insured rather than the two added together. The real value of income protection is in the illness claims where ACC pays nothing at all.
Does ACC cover me if I am self-employed?
Yes, you are covered for injury like everyone else, but the calculation of weekly compensation is based on your past earnings, which can be a poor reflection of what you earn now. CoverPlus Extra lets the self-employed agree a cover level in advance instead, which removes that uncertainty.
Does ACC cover mental health conditions?
Only in limited circumstances — such as a mental injury arising from a covered physical injury, or from specified events. Mental illness on its own is generally outside the scheme. Whether a private policy responds depends on the wording and on any exclusion applied at underwriting.
What happens if ACC says my problem is degeneration, not injury?
Then it is generally outside ACC, and you are relying on private cover or on nothing. This grey zone — whether a back or joint problem is an injury or the result of gradual wear — is genuinely fought over, and the financial consequences of the answer are significant. It is one of the strongest arguments for holding income protection regardless of how safe your job is.
