ACC CoverPlus Extra covers injury only. Income protection covers illness too. Here is where the line falls, whether the self-employed need both, and how the two coordinate without paying twice.
If you are self-employed in New Zealand, two products keep coming up when people talk about protecting their income: ACC CoverPlus Extra (CPX) and private income protection insurance. They sound like they do the same job, and that is where a lot of self-employed people get caught out. They do not. One covers injury, the other covers injury and illness — and the gap between them is exactly the thing most people would want covered.
This guide explains what each product does, why injury versus illness is the line that decides what you need, and how the two coordinate if you hold both.
TL;DR: ACC CoverPlus Extra pays for injury only — never illness.18 Income protection covers both illness and injury, typically up to about 75% of income.7 Many self-employed people hold CPX for injury and add income protection for illness, then coordinate the two with offsets so they are not paying twice for accident cover.
What does ACC CoverPlus Extra actually cover for the self-employed?
ACC CoverPlus Extra is an optional, agreed-value version of ACC work cover. You and ACC agree a cover amount up front, and if an injury stops you working, ACC pays 100% of that agreed figure (before tax) as weekly compensation — regardless of what your business is actually earning, and with no proof of lost income required at claim time.8
For the levy year 1 April 2026 to 31 March 2027, the agreed cover you can choose under CPX runs from a minimum of $40,401 to a maximum of $125,313.3 That is the band CPX works within for the self-employed.
The key word in all of this is injury. ACC covers personal injury — injury caused by accident, certain work-related conditions, and treatment injury. It does not cover general illness or sickness.1 So CPX is genuinely strong cover for one half of the risk you face, and silent on the other half.
What does income protection cover that ACC never will?
Income protection insurance is private cover you buy from an insurer rather than ACC. Its defining feature is that it replaces a portion of income lost due to both illness and injury — filling the sickness gap that ACC leaves entirely open.7 Agreed-value or indemnity income protection typically replaces up to about 75% of pre-disability income.7
That difference matters because, for most self-employed people, illness is at least as likely a reason for an extended period off work as an accident. Cancer, a cardiac event, a degenerative back condition, a serious mental-health condition — none of these are injuries, so ACC pays nothing.1 Income protection is the product built to respond to them.
Income protection is a contract with terms. Whether a claim is paid depends on the policy's terms, conditions, exclusions, stand-down periods and underwriting, and on the disclosure made when the cover was set up. This is a summary only — always read the policy wording.
Why injury vs illness is the line that decides what you need
Almost every decision in this area comes back to one question: was it an injury, or was it an illness? ACC answers only the first. Income protection answers both. The figure below shows how the same set of common scenarios splits across the two.
Injury vs illness: which cover pays
| Scenario | ACC CoverPlus Extra | Income protection |
|---|---|---|
| Broken leg from a fall | Pays (injury)8 | May pay, subject to wait period and terms7 |
| Cancer diagnosis | Does not pay (illness)1 | Pays, subject to terms7 |
| Heart attack | Does not pay (illness)1 | Pays, subject to terms7 |
| Back injury from a single workplace accident | Pays (injury)8 | May pay, subject to wait period and terms7 |
| Gradual/degenerative back condition (not from one accident) | Generally does not pay1 | Pays, subject to terms7 |
| Stress or mental-health condition (illness, not injury) | Does not pay (illness)1 | Pays, subject to terms7 |

Read down the "ACC CoverPlus Extra" column and the pattern is clear: it pays for the accidents and stays silent on the illnesses. That single column is the case for considering both products rather than one.

Do CoverPlus Extra and income protection overlap or stack?
This is where the agreed-value design of CPX matters. Because CPX pays 100% of a fixed amount you chose up front — rather than 80% of whatever you actually earned — it can be combined and coordinated with income protection rather than purely overlapping with it.8
For an illness, there is no overlap at all: ACC pays nothing, and income protection does the work.17 For an injury, both could potentially respond, and that is the part that needs coordinating so you are not insured twice for the same event.
The practical answer is that the two are usually structured to fit together, not to double up. Income protection policies are designed to take ACC into account through offsets, which is the next piece.
How do offsets coordinate the two if you have both?
An offset is a clause in an income protection policy that reduces the insurer's payment by other income-replacement money you receive for the same disability — including ACC weekly compensation.
The logic is straightforward. If you are off work because of an injury, ACC may pay weekly compensation — up to 80% of pre-incapacity earnings once you have been off for the first week.2 An income protection policy with an ACC offset then pays the difference up to the benefit it insures, rather than its full benefit on top of ACC. For an illness, ACC pays nothing, so there is no offset to apply and the income protection benefit pays in full, subject to its terms.1
Used well, offsets let you cover both injury and illness without paying twice for accident cover. The benefit you are really buying with income protection, once ACC is in the picture, is illness cover plus any top-up where ACC falls short on injury.
Where ACC can fall short on injury is the cap. ACC weekly compensation is based on liable income up to a maximum — $156,641 for the 2026/27 levy year (up from $152,790 in 2025/26).4 Because ACC pays 80% up to that cap, the effective maximum works out to roughly $2,409 a week (80% of $156,641 ÷ 52).5 Higher earners whose income sits above that ceiling have a genuine gap that income protection can fill — even on the injury side.
A note on accuracy: CPX itself is agreed-value, so its payment is the figure you agreed, not 80% of past earnings. The 80% and the $156,641 cap above describe how ACC weekly compensation is calculated generally; how they interact with a CPX policy and an income protection offset depends on how each is set up.
What's the cheapest way to cover both injury and illness?
There is no single answer that fits everyone, because the cheapest sensible structure depends on your income, how variable it is, your levy classification, and your health. But the general shape many self-employed people land on looks like this:
- Use ACC CPX for the injury half. You are already paying ACC levies — the earners' levy alone is $1.75 per $100 of liable earnings from 1 April 2026, to a maximum of $2,741.22 on income up to the $156,641 cap.6 Setting CPX at a deliberate, accurate cover amount makes that spend work harder rather than leaving you on an old auto-set minimum.
- Use income protection for the illness half, structured with an ACC offset so you are not buying duplicate injury cover.
- Align the wait periods and benefit periods of the two so there are no awkward gaps or expensive overlaps between when ACC stops and the policy starts.
Whether that is genuinely the lowest total cost for you depends on the numbers. Buying a large income protection benefit without an ACC offset gives broader injury cover but costs more in premium. There is a trade-off, and it is worth pricing rather than assuming.
We're generally paid by commission from the insurer when you take out a policy through us; this doesn't change the premium you pay. We work with a panel of selected insurers, listed in our disclosure, and manage any conflicts in line with our duty to prioritise your interests.
When is CoverPlus Extra alone genuinely enough?
CPX on its own can be a reasonable position for some people — it is not automatically incomplete. It may be enough where:
- You have substantial savings or other income that could carry you through an extended illness without insurance.
- A partner's income could support the household if illness stopped your earnings.
- Your health or budget makes private income protection hard to obtain or afford, and CPX is the cover you can realistically hold.
The honest version is that CPX alone leaves illness uncovered.1 That is fine if something else covers that risk; it is a real exposure if nothing does. The point is to make it a deliberate choice rather than an accidental gap.
How do you build a self-employed cover plan that has no gaps?
Pulling it together, a self-employed plan that covers both halves of the risk usually involves a few deliberate steps.
1. Confirm your ACC cover type and amount. Check whether you are on CoverPlus or CoverPlus Extra, and whether the agreed CPX figure still matches your real income. Our CoverPlus vs CoverPlus Extra guide walks through that choice.
2. Decide how injury and illness will each be covered. ACC for injury; income protection for illness and any injury top-up above the ACC cap.
3. Coordinate the two with offsets, wait periods and benefit periods so they fit rather than duplicate.
4. Check the rest of the self-employed picture — KiwiSaver, life and other cover — using our self-employed financial checklist.
5. Review it annually, because levy bands, the ACC cap and your own income all move.

Frequently asked questions
Does ACC CoverPlus Extra cover illness? No. ACC covers personal injury only — injury from an accident, certain work-related conditions, and treatment injury. It does not pay for general illness or sickness, so CPX pays nothing if cancer, a heart condition or another illness stops you working.1 That is the main reason many self-employed people add income protection alongside it.
Do I need both ACC CoverPlus Extra and income protection? Many self-employed people choose to hold both — CPX for injury and income protection for illness — and coordinate them with offsets. Whether you need both depends on your savings, other income and health. Some people are comfortable with CPX alone; for others the uncovered illness risk is too large. This is general information, so the right answer depends on your situation.
Will I be paying twice if I hold both? Not if they are coordinated. Income protection policies commonly include an ACC offset, which reduces the insurer's payment by ACC weekly compensation for the same injury, so you are not insured twice for accidents.8 For illness, ACC pays nothing, so income protection does the work on its own.1
How much does ACC pay if I am injured? ACC weekly compensation pays up to 80% of pre-incapacity earnings after the first week off.2 Capped at the maximum liable income of $156,641 for 2026/27, the effective maximum is roughly $2,409 a week.45 Under CPX, ACC pays 100% of the agreed cover amount, up to the CPX maximum of $125,313 for 2026/27.38
How much of my income does income protection replace? Agreed-value or indemnity income protection typically replaces up to about 75% of pre-disability income, and it covers both illness and injury.7 The exact figure, wait period and benefit period depend on the policy and how it is set up.
Is income protection worth it if I already have CPX? It can be, because CPX covers injury but not illness, and illness is a common reason for extended time off work.1 Income protection is the product that responds to illness, and it can also top up ACC for higher earners whose income sits above the ACC cap.57 Whether it is worth it for you depends on your finances and health.
