ACC Versus Income Protection Insurance: What New Zealanders Actually Need

The Short Answer

ACC covers injuries from accidents. It does not cover illness. Income protection insurance covers both. If you are a self-employed tradesperson diagnosed with bowel cancer, ACC pays nothing for the months you spend off work. No weekly compensation, no rehabilitation support. You are entirely on your own unless you hold private cover.

We regularly sit down with households that assume ACC replaces 80% of all lost income. It replaces 80% of accident-related income only, up to a capped amount, and nothing at all for illness. Industry data from the Financial Services Council of New Zealand indicates illness is roughly twice as likely as injury to keep a working-age New Zealander off work for an extended period. ACC and income protection serve different purposes and work as complements: ACC handles accident-related injuries up to a cap, while income protection handles illness, mental health conditions, and the income above that cap.

How ACC Works

New Zealand's Accident Compensation Corporation operates under the Accident Compensation Act 2001. It is a no-fault scheme: if you suffer a personal injury caused by an accident (as defined in section 25 of the Act), ACC covers treatment costs, rehabilitation, and income replacement regardless of who was at fault. Everyone in the country is covered, including visitors.

ACC pays weekly compensation at 80% of your pre-injury earnings, subject to a cap. For the year from 1 July 2025 to 30 June 2026, that cap sits at approximately $2,418 per week, based on maximum insurable earnings of around $157,209 per year (set annually by Order in Council under the Accident Compensation Act 2001). Anyone earning above that threshold receives less than 80% replacement from ACC.

ACC does not pay for the first week of incapacity. If the injury is work-related, your employer covers that first week at 80% of your usual pay. If the injury happened outside work, such as a cycling crash on a Saturday morning, there is no statutory obligation on your employer to cover the gap. You absorb it through sick leave, savings, or simply going without.

ACC is not free. It is funded by levies. Employees pay the earner levy (deducted from wages). For someone earning $80,000, that is roughly $1,100 per year (based on the current ACC earner levy rate). Employers pay the work levy, and self-employed workers pay both. ACC is a universal safety net for accidents, but its scope ends at accidents.

What ACC does not cover

• Cancer, heart disease, stroke, and other serious illnesses
• Mental health conditions (depression, anxiety, burnout) unless they are a direct consequence of a covered physical injury or meet the criteria for work-related mental injury under section 21B of the Accident Compensation Act 2001
• Gradual-process conditions (repetitive strain, chronic fatigue) unless they qualify as occupational diseases linked to your work
• Age-related degeneration
• Contagious diseases
• Injuries sustained during extended periods overseas (coverage rules are limited under the Act)

The mental health exclusion deserves emphasis. Mental health conditions are among the leading causes of long-term work absence in New Zealand, and standalone mental illness falls entirely outside ACC's scope. Section 21B of the Act covers work-related mental injury only in narrow circumstances, broadly where the worker was exposed to a specific traumatic event at work. If burnout or a depressive episode stops you from earning for six months, ACC pays nothing.

How Income Protection Insurance Works

Income protection (sometimes called income replacement insurance) is private cover that pays a monthly benefit if you cannot work due to illness or injury. It fills the gap ACC was never designed to cover. Policies typically replace up to 75% of your pre-disability gross income and can be structured to pay until you recover, for a fixed period (two or five years), or through to age 65.

Two structural features shape every policy and its cost:

• Wait period (stand-down). The number of weeks between when you stop working and when the insurer starts paying. Common options are 4 weeks, 8 weeks, or 13 weeks. A longer wait period means a lower premium, so matching this to your sick leave entitlement and emergency fund is a practical way to manage cost.
• Benefit period. How long the insurer will keep paying if you remain unable to work. A two-year benefit period is cheaper than a to-age-65 policy, but the financial consequences of a claim lasting longer than two years are severe.

How income protection interacts with ACC

Most income protection policies include an ACC offset provision. If you are injured in an accident and ACC is paying weekly compensation, the insurer reduces its payment so the combined total does not exceed your insured benefit (typically 75% of income). ACC pays first and the insurer tops up the difference. For an illness claim, ACC pays nothing and the insurer covers the full benefit amount. The scenarios later in this article show exactly how this plays out in dollars.

The Gaps That Cost the Most

Illness

Cancer, cardiovascular disease, and stroke account for a large share of long-term work absences. Industry estimates suggest roughly one in three working New Zealanders will experience a health event lasting more than three months before age 65. Every one of those illness-related absences falls outside ACC. Under the Holidays Act 2003, most employees are entitled to just 10 days of sick leave per year. That is enough for a bad flu, not for cancer treatment or cardiac rehabilitation.

Vinessa Orsbourn, Private Wealth and Risk Manager at Become Wealth: "Most people we sit down with have never added up what their household actually needs each month and compared it to what ACC would pay. The gap is usually larger than they expected."

It is also worth noting that health insurance covers treatment costs, while income protection replaces lost earnings. They solve different problems, and one does not substitute for the other.

Mental health

ACC covers mental injury only in the narrow circumstances defined by section 21B of the Accident Compensation Act 2001: where the mental injury is a direct consequence of a covered physical injury, or where it results from exposure to a specific traumatic event at work. Anything outside those criteria, including depression, anxiety, or burnout unrelated to a workplace trauma, receives nothing from ACC. An income protection policy with standard illness cover typically includes mental health conditions, subject to the policy terms and any pre-existing condition exclusions.

High earners above the ACC cap

If you earn well above $157,209, ACC's 80% replacement applies only up to the cap. The remainder comes from savings or debt unless you hold income protection insured at your actual income level. The Priya scenario below shows the dollar impact for a $210,000 earner.

Self-employed with variable or outdated earnings records

Under ACC's default CoverPlus arrangement for self-employed workers, compensation is calculated from liable earnings as declared to IRD. If your tax returns are behind schedule or your income has grown significantly since the last return was filed, the compensation figure may bear little resemblance to what you actually earn. CoverPlus Extra (CPX) allows you to nominate an agreed compensation level in advance, giving certainty, though levies are calculated on the higher nominated amount. Even with CPX, illness remains uncovered. For anyone self-employed, income protection is less a luxury and more a business continuity requirement.

What to Look for in a Policy

Policy wording varies between insurers, and the details determine whether a claim is paid. Three features deserve close attention:

• ‍Own occupation versus any occupation. An "own occupation" definition pays the benefit if you cannot perform the specific occupation you held before becoming disabled. An "any occupation" definition pays only if you cannot perform any work suited to your education, training, or experience. A surgeon who can no longer operate but could theoretically manage a clinic might receive nothing under an "any occupation" definition. If you have a skilled or specialised role, check this clause before you sign.‍
• Agreed value versus indemnity. An agreed-value policy locks in your insured income level at the time you take out the policy, regardless of earnings changes at claim time. An indemnity policy bases the benefit on your actual income at the time of claim, which can be lower if your earnings have dipped. Agreed value typically costs more but removes a potential dispute at claim time. This distinction matters most for self-employed workers whose income fluctuates year to year. If your claim falls in a down year, an indemnity policy could pay significantly less than you planned for.‍
• Pre-existing conditions. Insurers assess your medical history at application. Conditions disclosed (or that should have been disclosed) at that point may be excluded or loaded with a higher premium. Full disclosure upfront avoids disputes later.

Two people with similar incomes can receive very different policy terms depending on their occupation class, health history, and the insurer's appetite. A desk-based professional and a commercial diver will see meaningfully different premiums and conditions, even at the same income level.

What Does It Cost?

Less than most people assume. As at early 2026, a 40-year-old professional earning $120,000 per year might pay roughly $85 to $120 per month for an income replacement insurance policy covering approximately $5,000 per month (based on indicative quotes from major NZ insurers). The exact premium depends on occupation, wait period, and benefit duration. Extending the wait period from four weeks to thirteen weeks, or shortening the benefit period from age 65 to five years, can reduce premiums meaningfully.

For self-employed policyholders, premiums are generally tax-deductible where the insurance replaces taxable income. This position is grounded in the general deductibility provisions of the Income Tax Act 2007 and detailed in IRD Interpretation Statement IS 07/01. Benefits received under a deductible policy are treated as taxable income. For employees paying premiums from after-tax personal income, the premiums are not deductible, but the benefits received are generally tax-free. The deductibility makes a real difference to the effective cost for self-employed policyholders. A $100 monthly premium effectively costs closer to $67 after tax at a 33% marginal rate.

Cost management comes down to three levers: wait period length, benefit period length, and reviewing your cover periodically to ensure you are not over-insured relative to your actual obligations. Insuring 75% of income when your fixed costs only require 55% is paying for cover you may not need.

Real-World Scenarios

Employee diagnosed with cancer

Laura, 38, earns $95,000 as a marketing manager. She is diagnosed with breast cancer and faces surgery, chemotherapy, and a recovery period totalling ten months off work. ACC pays nothing because this is illness, not an accident. Her employer provides the statutory minimum of 10 sick days under the Holidays Act 2003 (some employers offer more, but Laura's does not). After that, her income stops. With income protection at 75% of earnings and a four-week wait period, she receives approximately $5,300 per month for roughly nine months, totalling close to $47,700. Without it, she faces ten months with effectively no income while managing treatment costs and mortgage payments.

Self-employed plumber injured on site

Jake, 42, is a self-employed plumber earning $110,000. He falls from a ladder and breaks both wrists. ACC accepts the claim and pays 80% of his liable earnings from his last tax return, which showed $90,000. That gives him roughly $1,385 per week, well below the $2,115 per week his current income represents. His income protection policy, insured at 75% of $110,000, provides an insured benefit of approximately $1,588 per week. The insurer pays the difference between ACC's $1,385 and the insured $1,588: a top-up of about $203 per week. Had he enrolled in CoverPlus Extra at his actual income level, the ACC payment would have been higher, but the top-up principle remains the same.

High earner above the ACC cap

Priya, 50, earns $210,000 as a specialist consultant. She is injured in a car accident and unable to work for six months. ACC pays the maximum of approximately $2,418 per week. Her actual weekly earnings are around $4,038. The shortfall of roughly $1,620 per week would come from savings. Her income protection policy, insured at 75% of her earnings, provides an insured benefit of approximately $3,029 per week. The insurer pays the difference between ACC's $2,418 and the insured $3,029: a top-up of about $611 per week, recovering roughly $15,886 over six months that would otherwise come from savings or debt.

Frequently Asked Questions

If ACC is paying me for an accident, will my income protection insurer also pay?

Yes, but only the top-up. The insurer offsets whatever ACC pays and covers the difference up to your insured benefit. You receive a combined total, typically 75% of your pre-disability income, not double payments.

Does the proposed NZ Income Insurance Scheme change any of this?

The scheme proposed in 2022, which would have covered redundancy and health-related job loss through a levy-funded model, was shelved by the current government and has no active legislative pathway. It should not be factored into current planning.

Can I claim income protection for a pre-existing condition?

Only if the condition was disclosed at application and the insurer chose to cover it (sometimes with an exclusion rider or premium loading). Conditions that were not disclosed, or that were specifically excluded, will not be paid at claim time.

Is trauma insurance the same as income protection?

They serve different purposes. Trauma insurance pays a one-off lump sum on diagnosis of a specified serious illness (cancer, stroke, heart attack). Income protection provides ongoing monthly payments replacing lost income. Some people hold both: the lump sum covers immediate medical costs and adjustments, while income protection maintains cash flow during recovery.

Why Your Income Deserves the Same Protection as Your House

Your ability to earn an income funds your mortgage, your household, your retirement savings, and the financial goals that matter most to your family. Over a working life, that earning capacity is likely worth well over a million dollars, which makes it, by a wide margin, your most valuable financial asset. ACC protects a slice of it: accident-related injuries up to a capped amount. Income protection covers the rest.

A useful first step is to add up what your household actually needs each month and compare that to what ACC would pay if you were injured, and what anyone would pay if you were ill. If your situation involves specific complexity, such as self-employment with outdated tax returns, income well above the ACC cap, or pre-existing conditions that need careful disclosure, our insurance advisers can work through the numbers with you.
