Life Insurance and Income Protection: Do Kiwis Need Both?

[Life Insurance](/life-insurance) and [Income Protection](/income-protection): Do Kiwis Need Both?

It is one of the most common questions New Zealand financial advisers hear: do I really need both life insurance and income protection, or can I get away with just one?

The question is understandable. Insurance premiums are a real household cost, and when you are already managing a mortgage, KiwiSaver contributions, and daily living expenses, it is natural to look for ways to simplify. But the answer, for most working Kiwis with financial obligations, is that these two products address different risks - and having one without the other creates a gap that could prove devastating at precisely the wrong moment.

This article takes an analytical approach to the question. Rather than simply asserting that you need both, we examine the specific risks each product covers, identify the scenarios where one or both may be unnecessary, and provide a practical framework for making the decision based on your actual financial circumstances.

What Each Product Actually Does

Before assessing whether you need both, it is essential to understand what each product does - and, critically, what it does not.

Life insurance pays a tax-free lump sum to your beneficiaries when you die or are diagnosed with a terminal illness. The purpose is capital replacement: providing your family with the financial resources to clear debts, maintain their living standard, and fund future needs in your permanent absence. Once the lump sum is paid, the policy is complete.

Income protection pays a regular monthly benefit - typically up to 75% of your pre-tax income - if you cannot work due to illness or injury. The purpose is income replacement: maintaining household cash flow during a period of incapacity so your family can continue meeting its financial obligations while you recover. The benefit continues until you return to work, reach the end of the benefit period, or reach the policy's age limit.

The distinction is fundamental. Life insurance protects your family if you are gone permanently. Income protection protects your household if you are alive but cannot earn.

Life Insurance Income Protection
Pays when Death or terminal illness Unable to work due to illness/injury
Payment type Single lump sum Ongoing monthly payments
Duration One-off Until recovery or benefit period ends
Purpose Replace financial capital permanently Replace income temporarily
ACC overlap None ACC covers accidents; IP covers illness too

The Statistical Case

The question of whether you need both products is partly a statistical one. What are the actual probabilities of each risk?

According to data from multiple NZ insurers, the probability of a working-age adult experiencing a period of significant illness or injury that prevents work is substantially higher than the probability of death during those same working years. Partners Life's 2024-25 claims data shows the company paid $60.7 million in income protection claims - a figure that reflects the genuine frequency of incapacity events among working-age policyholders.

The Financial Services Council NZ has reported that one in seven New Zealand households experienced a serious illness event in the past five years resulting in inability to work for three months or more. These are not rare occurrences.

Meanwhile, ACC's annual data confirms the scheme paid $8.23 billion in injury-related claims in 2024-25. But ACC only covers accidents. According to research consistently cited across the industry, approximately 80% of long-term work absences are caused by illness, not accidents. This means the single greatest threat to your income - illness - has no government safety net whatsoever.

For life insurance, the risk is lower in absolute probability terms for younger adults but the financial consequence is total and permanent. A 35-year-old non-smoker has a relatively low probability of dying before 65, but the impact on their family if they do is catastrophic and irreversible.

When You Might Not Need Both

While most working Kiwis with financial dependants benefit from both products, there are legitimate scenarios where one or both may be unnecessary.

Scenarios Where Life Insurance May Not Be Needed

No financial dependants. If nobody relies on your income - no partner, no children, no ageing parents you support - the core purpose of life insurance (protecting dependants) does not apply. You may still want a modest policy to cover funeral costs or debts, but a large life insurance sum is unnecessary.

Sufficient existing assets. If your household has accumulated enough wealth that your death would not create a financial crisis - for example, a mortgage-free home, substantial savings, and a partner with independent income - life insurance may be redundant. This is rare for younger families but increasingly common approaching retirement.

Employer-provided cover only. Some employers provide group life insurance as a benefit. If the cover amount is adequate for your situation, you may not need additional personal cover. However, be aware that employer cover ceases when you leave that employer.

Scenarios Where Income Protection May Not Be Needed

Approaching retirement with substantial savings. If you are within a few years of retirement and have sufficient KiwiSaver and other savings to cover expenses, the cost-benefit of income protection may not justify the premiums.

Your partner can fully support the household. In dual-income households where the partner's income alone can comfortably cover all expenses, income protection on the lower earner may be less critical (though still valuable for maintaining the full lifestyle).

You are self-funding through savings. If you have genuinely liquid savings sufficient to cover 12-24 months of living expenses, you are effectively self-insuring against medium-term illness. This requires discipline and a substantially higher savings level than most Kiwis maintain.

When You Definitely Need Both

There are household profiles where both products are unambiguously necessary.

Single-income families with a mortgage. If one person's income services the mortgage and funds the household, both risks - death and incapacity - would be financially devastating. Life insurance protects against the permanent loss; income protection protects against the (more likely) temporary loss.

Self-employed individuals. Without employer-provided sick leave, every day of illness is a day without income. And without ACC coverage for illness, there is no government backstop. Income protection is arguably the single most important financial product for self-employed Kiwis, and life insurance remains critical if others depend on the business income.

Families with young children. The financial obligations of raising children extend over 15-25 years. A serious illness in the primary earner's late 30s or 40s - when household costs are highest - without income protection could force the family to drastically reduce their standard of living or exhaust savings during the very years those savings are most needed.

People with significant debts. High mortgage balances, business loans, or other fixed obligations do not pause for illness. Without income to service them, default becomes a real risk within months.

The Cost of Holding Both

A common concern is that holding both products is too expensive. Let us examine the actual numbers.

For a 35-year-old healthy non-smoker earning $100,000:

Cover Specification Indicative Annual Premium
Life insurance $1 million, stepped $500 – $800
Income protection 75% of income, 13-week wait, 5-year benefit $800 – $1,300
Combined $1,300 – $2,100

The combined cost of approximately $25 to $40 per week provides protection against both the permanent loss of an income earner and the temporary loss of earning capacity due to illness. For context, this is comparable to a modest gym membership or a weekly family takeaway order.

Several insurers offer multi-policy discounts when you bundle life and income protection. AIA, for instance, offers up to 15% off when purchasing multiple eligible products. These discounts can reduce the combined cost meaningfully.

For budget-constrained households, there are levers to reduce cost without eliminating cover: extending the income protection waiting period from 4 weeks to 13 weeks (reducing premiums by 30-40%), choosing a 2-year benefit period instead of 5-year or to-age-65, or selecting level premiums on life insurance to reduce long-term total cost even though the initial premium is higher.

A Decision Framework

To determine what combination of cover is appropriate for your household, work through the following questions:

1. Does anyone depend on my income? If yes, life insurance is essential. If no, life insurance is optional (consider a modest policy for funeral costs and debts only).

2. Could my household survive financially if I could not work for 6-12 months? If no, income protection is essential. If yes (genuinely, accounting for mortgage, living costs, and no ACC coverage for illness), income protection may be lower priority.

3. Am I self-employed or a contractor? If yes, income protection should be the top priority - no employer sick leave and no ACC for illness means every day of illness is a day without income.

4. Do I have sufficient liquid savings to self-insure? If you have 12+ months of living expenses in readily accessible savings, you have more flexibility. If your savings would last less than 3 months, both products are critical.

5. What is my budget? If budget forces a choice between products (which it should not, given the relatively modest cost of both), prioritise income protection. The statistical probability of needing income protection is higher than the probability of a life insurance claim during working years.

How They Work Together in Practice

Consider a real-world sequence for a 42-year-old named David who is diagnosed with bowel cancer.

Month 1-3: David undergoes surgery and begins chemotherapy. He cannot work. His income protection policy has a 4-week waiting period, so after week 4, monthly payments of $6,250 (75% of his $100,000 income) begin flowing to cover the mortgage, utilities, and household expenses.

Month 3-12: David continues treatment and recovery. Income protection payments continue. His family maintains their standard of living. His life insurance policy remains in force but is not triggered - David is alive and his prognosis is positive.

Month 12: David returns to work part-time. His income protection policy pays a partial benefit to supplement his reduced earnings until he is back to full capacity.

Month 14: David returns to full-time work. Income protection payments cease. His life insurance policy continues, providing ongoing protection for his family.

In this scenario - which reflects one of the most common claim journeys - income protection was the product that made the difference. Life insurance provided peace of mind throughout but was not needed. Without income protection, David's family would have faced 10+ months of mortgage payments, bills, and living costs on no income (ACC does not cover cancer).

Now consider the alternative scenario where David's cancer is more aggressive and is ultimately terminal. Income protection covers the family throughout the treatment period. When David passes away, the life insurance lump sum clears the mortgage and provides long-term capital for the family. Both products were needed; each served its distinct purpose.

Common Mistakes

Having life insurance but not income protection. This is the single most common gap in New Zealand personal insurance. You are covered for the lower-probability event (death) but not the higher-probability event (extended illness).

Relying on ACC for all scenarios. ACC covers accidents only. The majority of long-term work absences - and the majority of income protection claims - are illness-related.

Assuming employer sick leave is sufficient. Ten days of statutory sick leave does not cover a three-month recovery from surgery, let alone a 12-month cancer treatment journey.

Choosing based on price alone. The cheapest policy is not always the best policy. Claims acceptance rates, benefit definitions, built-in features, and insurer reputation at claim time all matter.

Delaying the decision. Both products are cheaper when you are younger and healthier. A health event that occurs before you have cover in place could make you uninsurable or significantly increase your premiums.

Frequently Asked Questions

Do I need both life insurance and income protection in NZ?

For most working Kiwis with financial dependants, yes. Life insurance protects your family if you die, while income protection replaces your income if illness or injury prevents you from working. These are fundamentally different risks, and having one without the other leaves a significant gap. The statistical probability of needing income protection during your working years is higher than the probability of a life insurance claim.

Which should I get first - life insurance or income protection?

If budget forces a choice, many financial advisers recommend prioritising income protection. Your ability to earn income is your largest financial asset, and the probability of being unable to work due to illness is higher than the probability of death during working years. However, if you have dependants who rely on your income, life insurance is also critical and the combined cost of both is often more affordable than people expect.

How much does it cost to have both life insurance and income protection?

For a 35-year-old healthy non-smoker earning $100,000, the combined cost is approximately $1,300 to $2,100 per year, or roughly $25 to $40 per week. Multi-policy discounts from insurers like AIA (up to 15%) can reduce this further. Extending the income protection waiting period from 4 to 13 weeks is another effective way to lower the combined premium.

Does ACC replace the need for income protection insurance?

No. ACC only covers accidents, which account for approximately 20% of long-term work absences. The remaining 80% are caused by illness - including cancer, heart disease, and mental health conditions - for which ACC provides nothing. Income protection is the only product that covers illness-related income loss, making it essential alongside any ACC entitlement.

Can I bundle life insurance and income protection with the same insurer?

Yes. Most major NZ life insurers - including AIA, Partners Life, Fidelity Life, and Asteron Life - offer both products and provide multi-policy discounts when you bundle them together. Holding both products with the same insurer simplifies administration and can reduce your total premiums, though it is worth comparing across providers to ensure the best fit for each product.
