Income Protection Wait Period vs Benefit Period in NZ (2026): The Trade-off That Sets Your Premium

The wait period and the benefit period are the two levers that decide what your income protection costs. Here's how each one works, how they price your cover, and how to pick a combination that fits your savings and your situation.

Two settings on an income protection policy do more to shape your premium than almost anything else: the wait period (how long you go without a benefit before payments start) and the benefit period (how long those payments can keep coming). Most people sign up on price without thinking much about either. But these two levers are where price and protection trade off against each other, and getting them right is the difference between paying for cover you don't need and being short when it matters.

This guide explains what each setting does, how they move your premium in opposite directions, and how your own savings and situation point to a sensible combination.

TL;DR: A longer wait period lowers your premium; a longer benefit period raises it ²³. Wait periods commonly run from 2 to 104 weeks, and benefit periods from 2 years up to age 65 ²³. The benefit period matters most, because it caps how long your income is actually protected. Match the wait period to your savings buffer, not to the cheapest quote.

What is the wait period in income protection?

The wait period, sometimes called the stand-down or waiting period, is the gap between the day you become unable to work and the day your monthly benefit starts being paid. Choose a 4-week wait period and you carry the first four weeks yourself; the insurer's payments begin after that. Choose a 13-week wait period and you cover the first three months on your own.

NZ insurers offer a range of options. AIA, for example, publishes wait periods of 2, 4, 8, 13, 26, 52 or 104 weeks ². The principle is straightforward: the longer you agree to wait, the cheaper the cover, because you are asking the insurer to step in later and, in many cases, for less total time.

The wait period is best thought of as your excess, the same idea as the excess on your car or house insurance. You take on the short, survivable part of the risk yourself, and you insure the part you could not absorb on your own. The right wait period is therefore tied directly to how long you could keep the household running on savings, sick leave and any other cover before the benefit needs to kick in.

What is the benefit period, and why does it matter most?

The benefit period is the maximum length of time your monthly payments can continue once a valid claim starts. It is the ceiling on how long your income is actually protected. Common options include 2 years, 5 years, or cover through to age 65 (and to age 70 for some occupations) ³.

Here is why this setting matters more than the wait period. A wait period decides whether you wait four weeks or thirteen at the front end, a difference measured in weeks. A benefit period decides whether a serious, long-running illness is covered for two years or for the next twenty-five, a difference that can run to hundreds of thousands of dollars. If you are off work for six months, almost any benefit period covers you. If you are off work for a decade with a chronic illness, only a to-age-65 benefit period keeps paying.

The trade-off is cost. A to-age-65 benefit period is the most expensive option because the insurer is exposed to the longest and largest possible claims. A 2-year benefit period is much cheaper, but it quietly caps your protection at exactly the kind of long-term event that does the most financial damage. That is the central tension in this decision, and it is worth weighing deliberately rather than defaulting to whatever is cheapest.

How do wait and benefit periods change your premium?

These two settings pull your premium in opposite directions, which is what makes them useful levers. A longer wait period lowers the premium ². A longer benefit period raises it ³. You can use one to offset the other, for instance, lengthening the wait period to help afford a longer benefit period.

The pattern is consistent across the market: the cheapest combination is a long wait and a short benefit period (bottom-left), and the most expensive is a short wait and a long benefit period (top-right). Most people are best served somewhere in between, and the right spot depends far more on their circumstances than on the headline price.

A useful way to think about it: spend your premium where the risk is genuinely uninsurable on your own. A few weeks without income is uncomfortable but survivable for many households. A multi-year loss of income is not. That argues for protecting the back end (a longer benefit period) and self-funding more of the front end (a longer wait period) where your savings allow it.

How does your savings buffer set the right wait period?

The wait period should follow your savings, not the other way around. The question to answer is simple: how many weeks could the household keep running, on cash savings plus any sick leave, before the benefit has to start?

Most full-time employees have at least the statutory minimum of 10 days of sick leave a year under the Holidays Act ⁸, and many have annual leave to draw on as well. Layer an emergency fund on top and a salaried employee can often comfortably carry an 8 or 13-week wait period, which meaningfully reduces the premium. Someone self-employed with thinner leave entitlements and lumpier cash flow may want a shorter wait, even though it costs more, because they have less to fall back on in those first weeks.

A rough way to line it up:

Illustrative only; the right wait period depends on your full situation.

The mistake worth avoiding is buying a short wait period out of caution while sitting on six months of savings. You end up paying a higher premium to insure weeks you could easily cover yourself. The opposite mistake, a long wait period with almost nothing in the bank, is covered below. We go deeper on this trade-off in income protection vs a savings buffer.

Should you choose a 2-year, 5-year or to-age-65 benefit period?

This is the more consequential of the two decisions, because it sets the limit on your protection for the events that matter most. Each option suits a different situation.

• 2-year benefit period. The cheapest, and it covers the large majority of claims, which resolve within two years. The risk it leaves open is the smaller number of serious, long-running conditions that keep you off work for years. It can suit people who mainly want to bridge a temporary setback, or who have other assets to fall back on for a prolonged event.
• 5-year benefit period. A middle ground. It covers most long claims while keeping the premium below the to-age-65 option. Some people use it as a balance between cost and protection, particularly if they expect their financial obligations (a mortgage, dependent children) to ease within that window.
• To age 65 (or 70). The most complete and most expensive. It is the only option that protects against the worst case, a chronic illness or serious injury that ends your working life early. For someone whose household depends on their income and who would face real hardship from a permanent loss of earning capacity, this is often where the cover does its most important work.

There is no universally correct answer. The honest framing is that the longer benefit periods cost more precisely because they cover the events you most need covered. Whether that cost is worth it depends on your obligations, your other assets, and how exposed your household would be to a long-term loss of income. This is exactly the kind of trade-off worth talking through rather than guessing at.

What goes wrong with a wait period that's too long?

A long wait period is an easy way to cut the premium, and it is the right move for plenty of people. But it goes wrong in one specific way: when the wait is longer than you can actually fund.

If you choose a 13-week wait period but only have three weeks of expenses saved, you have a 10-week hole. During those 10 weeks the benefit has not started, your sick leave has run out, and the bills keep arriving. The cover technically exists, but it does not help you when the pressure is highest, in the first few months, which is when most short and medium claims sit anyway.

The other thing to watch is the interaction with illness. ACC covers injury and starts paying weekly compensation relatively quickly ⁴, but it does not cover illness at all. Income protection is the cover that fills the illness gap, and illness is behind a large share of long absences. If you set a long wait period assuming "something will tide me over", check that the something actually exists for an illness as well as an accident. We cover that distinction in off work through illness, not injury.

The fix is not to default to the shortest wait period. It is to match the wait period honestly to the buffer you genuinely have, and to revisit it if your savings change.

How do these settings interact with ACC and sick leave?

For injuries, ACC sits underneath your income protection, and most policies are designed to work alongside it rather than duplicate it. ACC pays weekly compensation at 80% of your pre-injury gross weekly earnings once its own stand-down ends, but only for injury, not illness ⁴. There is a cap: the maximum gross weekly compensation is $2,418.55 from the 1 July 2025 indexation, sitting on maximum liable earnings of $152,790 for the 2025/26 year ⁵⁹. There is also a minimum of $752.00 gross a week for a full-time earner ⁶. Higher earners face a gap above the cap that ACC does not fill.

The timing matters for your wait period choice:

• Work injury. Your employer must pay the first week at 80% of usual pay, and ACC weekly compensation then begins from day 8 ⁷.
• Non-work injury. There is no first-week compensation, so you rely on sick leave or annual leave during that week ⁷.
• Illness. ACC pays nothing, so the entire wait period is funded by you, until your income protection benefit starts.

Because ACC moves quickly for accidents but does nothing for illness, the wait period mainly bites on the illness side. That is the scenario to plan around. Sick leave (a minimum of 10 days a year ⁸) and savings are what bridge an illness wait period, and your income protection benefit picks up after that. Our explainer on why ACC is not income protection walks through the five places where relying on ACC alone leaves a household exposed.

How do you pick the combination that fits your situation?

There is no single right answer, but a few questions usually get you most of the way there:

• How long could you genuinely self-fund? Count savings, sick leave and annual leave in weeks. That number points to your wait period ⁸.
• How exposed is your household to a long-term loss of income? Mortgage, dependants and a lack of other assets all push toward a longer benefit period, because that is what covers the worst case.
• Are you employed or self-employed? Thinner leave and lumpier income tend to argue for a shorter wait period, even at a higher premium.
• Can you trade one lever for the other? Lengthening the wait period can help fund a longer benefit period, putting your premium where the risk is genuinely uninsurable on your own ²³.
• What does ACC already cover? For accidents, ACC does a lot of the work up to its cap ⁴⁵; the case for income protection is strongest on the illness side it does not touch.

Income protection in New Zealand typically replaces up to around 75% of your pre-tax income, because insurers will not let you insure more than you earn ¹. Within that, the wait and benefit periods are the dials that set both your premium and your real level of protection. Cover and these settings can be compared across major NZ insurers, including AIA, Partners Life, Fidelity Life, Asteron Life and Chubb Life, on definitions and price. Not every provider in the market is shown, and each insurer's product disclosure statement sets out its own terms.

Frequently asked questions

What is the difference between a wait period and a benefit period? The wait period is how long you go without a benefit after becoming unable to work, before payments start. The benefit period is the maximum length of time those payments can continue once a claim begins ²³. The wait period is your excess at the front end; the benefit period is the ceiling on how long your income is protected.

Does a longer wait period make income protection cheaper? Generally yes. Agreeing to a longer wait period lowers the premium, because the insurer starts paying later and, in many cases, for less total time ². The catch is that you must be able to fund that longer wait from savings, sick leave or other cover.

Which benefit period should people choose? It depends on exposure to a long-term loss of income. A 2-year benefit period is cheapest and covers most claims; a to-age-65 benefit period costs the most but is the only option that protects against a chronic illness or injury that ends your working life early ³. A 5-year period sits in between. There is no universally right answer.

How do I match the wait period to my savings? Work out how many weeks the household could run on cash savings plus any sick and annual leave, then choose a wait period around that length ⁸. More savings can support a longer, cheaper wait period; little or no buffer points to a shorter one, even though it costs more.

How does ACC affect my wait and benefit period choice? ACC pays weekly compensation at 80% of pre-injury gross earnings for injuries, capped at $2,418.55 gross a week from 1 July 2025, but it covers nothing for illness ⁴⁵. Because the wait period mainly bites on the illness side, plan it around what would bridge an illness, not just an accident.

Can I change my wait or benefit period later? Often you can request changes, but they are subject to the insurer's terms and may involve fresh underwriting, especially if you want shorter waits or a longer benefit period. It is worth reviewing these settings as your savings and circumstances change rather than assuming the original choice still fits.
