Income Protection Insurance NZ: Why Your Earning Power Is Your Biggest Asset

Income Protection Insurance in New Zealand: What It Is, What It Costs, and Who Needs It

Income protection insurance replaces up to 75% of your gross income if illness or injury stops you from working. A typical policy for a 35-year-old professional costs $80 to $150 per month. Most working New Zealanders with a mortgage or dependants are underinsured against this risk, largely because they assume ACC or their employer will cover them. In most illness scenarios, neither does.

Consider the asset at stake. A 40-year-old earning $120,000 per year with 25 years until retirement has roughly $3 million of future earning capacity ahead of them, assuming flat real wages. Even someone on the median New Zealand salary of approximately $69,836 (based on Stats NZ Household Labour Force Survey data, year ended June 2025) has about $1.75 million of remaining lifetime earnings at the same age. Most people would never leave a $3 million house uninsured, yet the majority leave an asset of equal or greater value completely unprotected against illness.

In client reviews, the moment this gap becomes real is when someone maps out what their household would actually receive, week by week, if they could not work for a year due to illness. The number is almost always far lower than they expected. That disconnect between what people assume is covered and what actually is drives most of the conversations we have about income protection.

What ACC, Sick Leave, and Government Benefits Do Not Cover

New Zealand has a layered system of support if you cannot work. Each layer sounds reassuring on its own. The problem is where each one stops.

Gap 1: ACC only covers accidents

Under the Accident Compensation Act 2001, ACC pays 80% of your pre-injury weekly earnings if you are incapacitated by an accident. The scheme covers personal injury caused by accidents, certain work-related gradual process injuries such as occupational hearing loss, and mental injury caused by specific covered events. It does not cover illness. Cancer, heart disease, stroke, most mental health conditions, degenerative conditions, and chronic pain from wear and tear all fall outside ACC's scope.

ACC's weekly compensation is also capped. For the 2026/27 year, the maximum insurable earnings are $156,641 per annum under the Accident Compensation (Earners' Levy) Regulations 2025. If you earn above the cap, ACC will not replace your full income even for an accident. For a detailed comparison, see our breakdown of how ACC and income protection differ.

Gap 2: your employer's sick leave runs out

The Holidays Act 2003 entitles employees to a minimum of 10 days' paid sick leave per year. Some employers offer several weeks or even a few months of paid medical leave. Either way, the clock is finite. A serious illness typically means months away from work, sometimes over a year. Once your sick leave is exhausted, your pay stops.

Gap 3: government support is subsistence level

If you cannot work due to illness, the main government benefit is Jobseeker Support (Health Condition or Disability) or, for permanent incapacity, the Supported Living Payment. As of 1 April 2026, a single person aged 25 or over receives $372.55 per week after tax (at "M") from Jobseeker Support according to Work and Income. The Standard Disability Allowance, a supplementary payment, adds a maximum of $82.85 per week on top. These rates are adjusted each April.

Combined, that is roughly $455 per week after tax. For someone earning $100,000, about $1,530 per week after tax, mortgage repayments alone will often exceed the entire benefit.

How Income Protection Insurance Works in New Zealand

If you are unable to work because of illness or injury, an income protection policy pays a monthly benefit for the length of your chosen benefit period or until you return to work, whichever comes first. The benefit is typically up to 75% of your gross pre-disability income. When you need to claim, you notify your insurer (usually through your adviser), provide medical evidence, and payments begin after your waiting period expires.

Several decisions are built into a policy, and each one affects both cost and coverage:

• Waiting period. The number of weeks between becoming unable to work and your first payment. Common options are 4, 8, 13, or 26 weeks. A longer waiting period reduces the premium because you are self-insuring the early weeks. Aligning your waiting period with your employer's sick leave provision is a practical way to manage cost.
• Benefit period. How long payments last if you remain unable to work. Options typically range from 2 years up to age 65. A two-year benefit period is significantly cheaper than cover to age 65, but it leaves you exposed if recovery takes longer.
• Own occupation vs any occupation. An "own occupation" policy pays out if you cannot perform your specific job. An "any occupation" policy only pays if you cannot perform any job you are reasonably suited to by education, training, or experience. Own occupation cover provides stronger protection and costs more.
• Agreed value vs indemnity. Agreed value locks in the insured amount when you take out the policy. Indemnity assesses your income at the time of claim. Agreed value typically costs 15 to 20% more but removes the risk of a lower payout if your income has dropped or fluctuated.

Tax treatment: For employees, premiums are paid from after-tax income and benefits are received tax-free. For self-employed people who claim premiums as a business expense, benefits are treated as taxable income. The after-tax outcome is broadly comparable, though the cash flow timing differs. Self-employed policyholders should account for the tax liability on any benefit received, ideally with their accountant, before assuming the full monthly amount is available to spend.

These choices mean two people on the same salary can end up with very different premiums and very different levels of protection. The configuration matters as much as the decision to get cover in the first place.

A Worked Example: With and Without Cover

Sarah is 38, earns $110,000 a year as a healthcare professional, and has a $550,000 mortgage with repayments of approximately $800 per week (assuming roughly 6.5% interest over 25 years). Her partner works part time, earning $45,000. They have two school-age children. Sarah is diagnosed with breast cancer and is unable to work for 14 months.

Without income protection: Because this is an illness and not an accident, ACC does not apply. Sarah's employer provides 10 days' paid sick leave, then four weeks on a discretionary basis. After that, her personal income drops from approximately $1,650 per week after tax to Jobseeker Support of $372.55 per week: a 77% pay cut. That is the figure that matters. Sarah personally loses nearly $1,280 per week. At the household level, her partner's after-tax income of around $750 per week brings the total to approximately $1,122 per week against essential expenses of about $1,500 per week. The shortfall of roughly $378 per week accumulates to over $19,600 in 12 months, and that assumes expenses do not increase during treatment. Savings drain fast. Selling the house becomes a real possibility.

With income protection (8-week waiting period, benefit to age 65, own occupation): After the waiting period, Sarah receives approximately $6,875 per month tax-free. That is 75% of $110,000, which equals $82,500 per year, divided by 12. Combined with her partner's income, the household can cover its expenses and maintain mortgage payments while Sarah focuses on treatment and recovery.

Approximate cost of the policy: For a 38-year-old professional in good health, a policy like this might cost $100 to $150 per month, depending on the insurer and specific terms. That is roughly $5 per working day to protect $110,000 of annual income. Two people with the same salary and occupation can receive different quotes depending on health history, smoker status, and the insurer. The numbers above are indicative, designed to show the scale of the gap.

Who Needs Income Protection in New Zealand

Anyone whose household would struggle financially if their income stopped for six months or longer.

That includes sole earners with dependants, dual-income families who rely on both salaries to meet their mortgage and living costs, and single people without a financial backstop. Dual-income households sometimes assume the other partner's income is the safety net, but in practice, most dual-income budgets are built around both salaries. Losing one does not halve expenses. The mortgage, rates, insurance, and school costs remain the same.

New parents and recently separated parents are particularly exposed. Their expenses have typically increased while their financial buffer has shrunk.

Self-employed people are the most exposed

If you are self-employed, you have no employer sick leave, no employer group cover, and no guaranteed income during recovery. You are also more likely to have irregular income, which makes the "agreed value" option worth considering. Insurers will require documentation of your income history (typically two to three years of financial statements or tax returns), and variable earnings can complicate both the application and any future claim. Self-employed premiums are generally tax-deductible as a business expense, with the trade-off that benefits received then become taxable income.

When you might not need it

If you are approaching retirement with sufficient invested assets to fund your lifestyle regardless of whether you work, the cost may no longer be justified. The same applies if you have substantial passive income streams or if you have deliberately built a self-insurance reserve large enough to bridge a prolonged period without earned income. An emergency fund of three to six months' expenses is valuable but typically not enough to cover a serious illness lasting a year or more. If you are weighing whether to reduce your insurance costs, income protection is usually the last cover to drop, not the first.

How Income Protection Fits Alongside Other Insurance

Income protection replaces lost income. It sits alongside three other forms of personal insurance, each addressing a different risk:

• Life insurance pays a lump sum if you die, protecting your dependants from debt and lost future income. The question of whether you still need life insurance as you approach retirement is a separate decision.
• Trauma insurance pays a lump sum on diagnosis of a specified critical illness such as cancer, stroke, or heart attack. It covers immediate costs and financial shock but does not replace ongoing income.
• Health insurance covers the cost of medical treatment: surgery, specialists, hospital stays. It can get you treated faster but does not replace the income you lose while recovering. There is a good reason to hold onto health insurance even when budgets are tight.

These products are complementary. Income protection is the one most New Zealanders are missing. The Financial Services Council's Money & You research into the perception gap (November 2023) found that only around 20% of New Zealanders hold income insurance, and roughly 70% of the population is underinsured overall.

Frequently Asked Questions

Can I get income protection if I have a pre-existing condition?

Usually, yes, but the insurer may exclude claims related to that condition or apply a loading (higher premium). Disclosure is essential: failing to declare a known condition can void a claim entirely.

Does income protection pay out for mental health conditions?

Most modern policies cover mental health conditions such as depression and anxiety, subject to the same definitions and waiting periods as physical illness. Some policies limit the benefit period for mental health claims to two years, even if the overall benefit period is longer. Check the policy wording before you commit.

What happens if I return to work part time during recovery?

Many policies include a partial disability or graduated return-to-work benefit, paying a reduced amount to bridge the gap between your part-time earnings and your pre-disability income.

How much does income protection cost in New Zealand?

It varies by age, occupation, health, smoker status, waiting period, and benefit period. As a rough guide, a 35-year-old office worker earning $100,000 might pay $80 to $150 per month for cover to age 65 with an 8-week waiting period. Premiums typically increase as you age and at policy renewal, particularly after age 50. Choosing a longer waiting period or a shorter benefit period brings the cost down, but reduces your protection. The only way to get an accurate figure is to request a quote based on your circumstances.

What is the difference between income protection and trauma insurance?

Trauma insurance pays a single lump sum when you are diagnosed with a specified serious illness. Income protection pays a monthly benefit for as long as you cannot work, up to your benefit period. Trauma cover helps with the immediate financial shock of a diagnosis; income protection replaces the ongoing income you lose during treatment and recovery. Many people hold both.

What happens when I make a claim?

You notify your insurer, usually through your adviser, and provide medical evidence confirming you are unable to work. The insurer assesses the claim against your policy definitions. If accepted, payments begin after your waiting period expires and continue monthly for as long as you remain unable to work or until your benefit period ends. The process typically takes two to four weeks from lodging the claim to the first decision, though complex cases can take longer.

Working Out Your Income Gap

The most useful exercise you can do takes five minutes: calculate what your household would actually receive, week by week, if you could not work for 12 months due to illness. Add up your employer sick leave, any group cover, and the government benefit you would qualify for. Compare that total to your actual household expenses.

If the gap is material, income protection belongs on your priority list. The areas where an adviser adds the most value are the ones with moving parts: coordinating a waiting period with your employer's sick leave, choosing between agreed value and indemnity when your income is variable, or structuring cover alongside ACC if you earn above the cap. If any of those apply to you, our advisory team can help you work through the numbers.
