Why ACC Is Not Income Protection NZ (2026): Five Limits to Know

ACC is accident cover, not an income plan. Here are the five limits, illness, the 80% cap, the stand-down and more, that catch Kiwis out, and what private income protection fixes.

ACC is a good scheme. It covers every New Zealander for accidents, no-fault, regardless of how the injury happened, and it pays weekly compensation while you recover. But ACC is accident cover. It was never built to be an income plan, and the gap between those two things is where households get caught. In plain terms, ACC is not income protection: it is the accident half of a much bigger picture.

A common assumption is that ACC covers any loss of income, including from illness. It does not. This article walks through the five places where "I'm covered for income because of ACC" stops being true.

TL;DR: Is ACC the same as income protection?

TL;DR: No. ACC is accident-only cover that pays 80% of pre-injury gross earnings, capped at $2,418.55 a week on earnings up to $152,790, after a one-week stand-down. It pays nothing for illness, which drives most long-term work absences. Income protection covers both illness and injury and replaces income above ACC's ceiling.

The key number is 80%. ACC's weekly compensation is 80% of your pre-injury gross weekly earnings, before tax ¹. That sounds close to whole. The five limits below are why it usually is not.

Limit 1: Illness gets nothing, and illness drives most long absences

This is the limit that does the most damage, and the one most people miss.

ACC covers personal injury by accident only. It does not cover illnesses, diseases, infections, age-related conditions, or non-work-related gradual-process conditions. Cancer, heart disease, stroke and mental illness are all excluded unless an accident caused them ⁵.

Now line that up against why people actually stop working. Illness, not injury, is behind most long-term absences from work, and ACC covers none of it. Horizon Research found that in the previous five years a serious illness had stopped 14.4% of New Zealand adults, around 1 in 7, from working for three to six months, and a further 14.3% for more than six months ⁶. The NZ Disability Survey tells the same story from another angle: 41% of impairments among disabled adults were caused by disease or illness, versus only 34% caused by ACC-covered accidents ⁷.

A Partners Life survey found 34% of people wrongly believed ACC would cover their illness ⁸.

What this means in plain terms

If you are diagnosed with cancer next month and cannot work for six months, ACC pays $0. Your sick leave runs out in weeks. After that, your income depends entirely on savings or private cover.

Limit 2: The 80% cap leaves higher earners short

Even for a genuine accident, ACC does not replace all of your income. It replaces 80% of your gross pay ¹, and only up to a ceiling.

For the 2025/26 year, ACC's maximum liable earnings, the income ceiling behind the weekly cap, is $152,790 ³. From 1 July 2025 the maximum gross weekly compensation is $2,418.55, a 2.89% adjustment on the prior year ². Earnings above the ceiling are simply not replaced.

There is also a minimum: a full-time earner (working 30+ hours a week before injury) gets at least $752.00 gross a week, which is 80% of the adult minimum wage ⁴. That helps lower earners, but does little for higher earners.

Worked example: the cap on a $200,000 income

Scenario: Priya is a self-employed specialist earning $200,000. An accident keeps her off work.

The higher you earn above $152,790, the further the effective replacement rate falls below 80%. Priya is not getting "80% of income". She is getting 61% of hers. This is exactly the kind of gap a quick run through an income protection calculator makes visible, so you know your real replacement rate rather than the headline 80%.

Limit 3: The one-week stand-down

ACC does not pay weekly compensation for the first seven calendar days of incapacity. Payments begin on day 8 ⁴.

What fills that first week depends on how you were injured:

• Work injury: your employer must pay 80% for the first week ⁹.
• Non-work injury: you fall back on your own sick leave, annual leave, or unpaid leave ⁹.
• Self-employed with a non-work injury: that first week is on you.

A week without pay is survivable for most salaried employees with leave banked. For the self-employed and contractors, it is a straight hit to cash flow at the worst possible moment.

Limit 4: Return-to-any-suitable-work pressure

ACC is a rehabilitation scheme, not a long-term income scheme, and the rules reflect that.

When your vocational rehabilitation finishes, ACC runs a vocational independence assessment. If ACC decides you can work full-time in any job suited to your experience, education and training, not necessarily your previous occupation, your weekly compensation continues for only three more months and then stops ¹⁰.

You do not have to be able to return to your own career. If ACC assesses that you could do some other full-time role you are notionally suited to, the income support is on a three-month countdown. A surgeon who can no longer operate but could, in ACC's view, do deskbound work may find compensation ending even though their earning capacity has collapsed. This is the practical difference between any-occupation cover (you are paid only while you cannot do any suitable job) and own-occupation cover (you are paid while you cannot do your own job): ACC works on the harsher any-occupation test, while good private income protection can be written own-occupation.

Limit 5: The self-employed first-year compensation trap

This limit often affects people who assume they are well covered.

If you have recently gone self-employed, ACC calculates your first-year weekly compensation from the PAYE earnings in the 52 weeks before your injury, divided by the weeks worked, then pays 80% of that. Your self-employment income is excluded because you have not yet filed a tax return for it. ACC's own guidance is blunt about the result: "If you had no PAYE earnings in the 52 weeks before your injury and you don't qualify for the full-time minimum rate, your weekly compensation payment may be zero dollars" ¹¹.

So you can be paying ACC levies, be a full-time business owner, have an accident, and discover your compensation is calculated off income you no longer earn, or off nothing at all.

The fix exists, but you have to set it up in advance. ACC CoverPlus Extra lets you pre-agree a fixed compensation amount regardless of your tax returns, which is exactly what the newly self-employed or those with variable income need ¹².

The two ACC products for the self-employed

If you are self-employed and have never reviewed which one you are on, that is a five-minute conversation worth having before anything goes wrong.

What private income protection fixes for each limit

Income protection insurance is built to do the job ACC was never designed for. Private cover in New Zealand typically replaces up to 75% of pre-tax income and, unlike ACC, can be set up to cover both illness and injury ¹³. Cover can be compared across major NZ insurers, including Partners Life, AIA, Asteron Life, Fidelity Life and Chubb, on definitions and price. Below are the same five limits, mapped to the fix.

Many policies are structured to sit on top of ACC for accidents (so you are not paying twice for what ACC already provides) while paying the full benefit for illness. That structure helps keep premiums down. With own-occupation, agreed-value cover, the wait period and benefit period are the two main levers: a longer wait period for someone with a solid emergency fund can cut the premium while still protecting against the scenarios that would seriously affect a household budget.

And the quiet sixth limit: your KiwiSaver stalls

There is a limit nobody puts on the ACC brochure. When your income stops, your KiwiSaver contributions stop too, and so does the free money attached to them.

KiwiSaver's full government contribution requires you to personally pay in at least $1,042.86 between 1 July and 30 June; do that and you get the maximum $260.72 a year ¹⁴. Budget 2025 halved the rate from 50c to 25c per dollar and dropped the maximum from $521.43 to $260.72, with a new $180,000 income cap, all from 1 July 2025 ¹⁵. Default contribution rates are also rising: 3% employee and 3% employer now, to 3.5% each from 1 April 2026, then 4% each from 1 April 2028 ¹⁶.

If illness or injury parks your income for a year, you can miss the $260.72 government contribution, lose the employer match on every dollar you would have contributed, and surrender the compounding on all of it. ACC weekly compensation, where it applies, does not carry KiwiSaver employer contributions with it. Income protection that keeps your household solvent is also, indirectly, what keeps your retirement plan on track. It is worth pairing this with a KiwiSaver review so the two sides of your plan are not working against each other, and worth checking your PIR while you are there.

If your income drops during a claim, your correct PIR can fall too, another small thing that quietly goes unadjusted ¹⁷.

Your checklist: stress-testing your reliance on ACC

01. Could you stop work for illness, not just accident? If yes, ACC covers none of it ⁵. This is the first thing to close.

02. Do you earn above $152,790? Everything over the ceiling is uninsured by ACC ³. Know your real replacement rate, not the headline 80%, an income protection calculator will show it in a minute.

03. How long could you go unpaid for the first week? Map the 7-day stand-down against your leave and savings ⁴.

04. Is your job genuinely interchangeable? If not, the return-to-any-suitable-work test could end your support after three months ¹⁰.

05. Self-employed? Check which ACC product you are on. If you went self-employed recently, confirm you are not exposed to a year-one $0 result, and look at CoverPlus Extra ¹¹¹².

06. Have you priced the KiwiSaver cost of a year off? Lost employer match plus the $260.72 government contribution plus compounding adds up ¹⁴¹⁵.

Frequently asked questions

Does ACC cover illness in New Zealand? No. ACC covers personal injury by accident only. Illnesses, diseases, infections, age-related and gradual-process conditions are excluded unless an accident caused them, so cancer, heart disease and mental illness generally fall outside ACC ⁵.

How much does ACC pay if I cannot work? ACC weekly compensation is 80% of your pre-injury gross weekly earnings, before tax, after a one-week stand-down ¹⁴. There is a maximum of $2,418.55 gross a week from 1 July 2025 and a minimum of $752.00 for full-time earners ²⁴.

What is the ACC income cap for 2025/26? ACC insures earnings up to maximum liable earnings of $152,790 for the 2025/26 levy year. Income above that ceiling is not replaced, so higher earners receive well below 80% of their actual income ³.

Why might a newly self-employed person get $0 from ACC? First-year compensation is based on the PAYE earnings in the 52 weeks before your injury, not your new self-employment income. ACC states that with no PAYE earnings and below the full-time minimum, your weekly compensation can be zero dollars. CoverPlus Extra lets you pre-agree an amount to avoid this ¹¹¹².

Can income protection and ACC work together? Yes. Many NZ income protection policies sit on top of ACC for accidents and pay the full benefit for illness, which ACC does not cover at all. This keeps premiums sensible while closing the illness gap ¹³⁵.

Does ACC stop even for a serious injury? It can. After vocational rehabilitation, if ACC's vocational independence assessment finds you could work full-time in any suitable job, weekly compensation continues for only three more months and then stops ¹⁰.
