The Retirement Income Gap NZ 2026: What NZ Super Leaves You Short Each Week

NZ Super pays a single about $555 a week. A no-frills metro single needs roughly $705. That weekly gap is the retirement income gap, and KiwiSaver is built to close it.

NZ Super is the floor, not the plan. From 1 April 2026 it pays a single person living alone about $555 a week after tax, and a qualifying couple about $854 a week combined.¹² Few people retire on those numbers and nothing else. Once you put real grocery, power, rates and running-a-car costs next to that payment, a retirement income gap opens up. That gap is what your KiwiSaver, and any other savings, has to fill each week for the rest of your life. Working out your own retirement income gap is the first job of any retirement plan.

This guide puts the 2026 NZ Super figures next to Massey University's latest retirement spending data, shows you the weekly gap for singles and couples, turns that weekly number into a lump-sum target, and explains exactly how KiwiSaver drawdown closes it.

TL;DR: The retirement income gap is the weekly shortfall between NZ Super and what you actually spend. In 2026 a no-frills metro single needs about $705/week but NZ Super pays roughly $555, a gap of around $150/week. A metro couple wanting "choices" faces a gap of about $926/week against 2026 Super (Massey models it at $951.98 on the older Super base).¹⁵ KiwiSaver drawdown is the main tool that fills it.

What is the retirement income gap?

The retirement income gap is the difference between what NZ Super pays you and what your retirement actually costs each week. NZ Super is a flat, universal payment set by the government and adjusted each 1 April. Your spending is set by where you live, whether you own your home, and the lifestyle you want. When your costs are higher than your Super, the difference is the gap, and you have to fund it from somewhere else.

Massey University's Retirement Expenditure Guidelines (REG) measure this every year using real household spending data. They split households two ways:

• No-frills — a basic standard of living that covers the essentials with little room for extras.
• Choices — a more comfortable lifestyle with travel, eating out, hobbies and home upgrades.

And then again by location, metro (the main cities) versus provincial. The combination of those four splits is why "how much do I need to retire?" has no single answer. Yours depends on which box you fall into.

How big is the gap for singles vs couples in 2026?

Here is the picture using NZ Super after tax from 1 April 2026¹² against Massey's 2025 REG weekly household spending.⁵ NZ Super is shown at the M tax code, which is what most retirees with no other significant income are on.

Table note on how the gaps are calculated: the "Weekly gap" column is simply Massey's weekly spend minus NZ Super at the new 1 April 2026 rates ($555.15 single / $854.08 couple combined).¹² Where we quote Massey's or Lifetime's own published gap figures elsewhere in this guide ($42.33 for the provincial no-frills single,³ $951.98 for the metro choices couple⁴), those were calculated against the slightly lower pre-1-April-2026 Super ($538.42 single / $828.34 couple combined), which is why they run a little higher than the table. Lifetime's source page flags that it will refresh once the June 2026 REG report is published. The two sets of numbers describe the same households; they just use a different Super base.

A few things jump out. The smallest gap is the provincial no-frills single, only about $26/week against 2026 Super (Massey published it at $42.33 on the older Super base).³ The largest is the metro couple chasing a choices lifestyle, where the 2026 gap is about $926/week (Massey published $951.98 on the older base).⁴ In other words the gap ranges from a rounding error to nearly a thousand dollars a week, depending entirely on lifestyle and location.

A note on the couple figures. First, a no-frills metro couple spends less per person than a no-frills metro single, because two people share rent, power and one set of rates, which is why the couple no-frills gap looks small. Second, in Massey's data the no-frills metro couple ($937.38) actually spends less than the no-frills provincial couple ($1,060.65). That looks back-to-front, but it is straight from the source: provincial no-frills couples in the survey spent more on transport and home upkeep than their metro counterparts that year. It is the choices couple number, not the no-frills one, that balloons.

Why the gap is bigger in cities and for 'choices' lifestyles

Two forces drive the size of your gap, and neither is mysterious.

Housing. Massey's metro figures include real city housing costs. If you own your home mortgage-free at 65, your gap is smaller. If you are still paying off a mortgage, or renting, the metro numbers above understate your reality, because rent in Auckland, Wellington or Christchurch does not stop when you turn 65.

Discretionary spending. The jump from no-frills to choices is almost entirely travel, dining, vehicles, gifts and home improvements. For a metro couple that single decision, "we want to keep travelling and eating out," moves the weekly gap from about $83 to about $926.⁵ It is the most expensive lifestyle choice most people never consciously make; they just assume retirement will look like the last few years of work.

The practical takeaway: your gap is not fixed by the government. It is mostly set by you, and the levers are housing and lifestyle.

How a weekly gap becomes a lump-sum target over 25 years

A weekly gap feels manageable. The lump sum behind it is what surprises people. A 65-year-old today can expect a long retirement: Stats NZ cohort life tables suggest a man reaching 65 in the early 2020s can expect roughly 26 more years and a woman roughly 28 more years, taking many into their early 90s and beyond.¹² Planning to your early 90s, a retirement of around 25 to 28 years, is sensible.

Worked example: a metro couple, choices lifestyle

Scenario: Maria and Tane retire at 65 in Christchurch, mortgage-free, wanting the "choices" lifestyle. Christchurch sits in Massey's metro bucket, so their weekly gap above NZ Super is about $926 against 2026 Super (Massey published $951.98 for this household on the older Super base; we use that source figure below).⁴

The naive sum, $951.98 a week for 52 weeks across 25 years, comes to about $1.24m. Massey's own modelling lands lower, at around $1.14m ($1,142,000) for a metro choices couple, and around $446,000 for a provincial choices couple.⁶ The realistic figure is below the naive multiplication because your savings keep earning a return while you draw them down. That return is doing real work, which is exactly why the fund you sit in matters.

For a single person with a smaller gap the target is far lower, but the principle holds: a modest-sounding weekly shortfall compounds into a six- or seven-figure savings goal once you stretch it across a retirement of 25 years or more.

How KiwiSaver drawdown closes the gap

This is the heart of it. NZ Super is the base layer; KiwiSaver is the top-up that turns your gap into an income. The job has two halves: build the balance before 65, then draw it down after.

Contributions before 65: building the balance

From 1 April 2026 the default minimum KiwiSaver contribution rate rises from 3% to 3.5% for both employee and employer, then to 4% from 1 April 2028. Employees can also elect higher rates of 4%, 6%, 8% or 10%.⁹ Employer contributions are paid on top of your own and are taxed at your ESCT rate before they land in your account.¹¹ On top of your own contributions, the government adds a contribution each KiwiSaver year (1 July to 30 June) if you put in enough of your own money.

Budget 2025 halved the government contribution to 25c per dollar, so the most you can now get is $260.72, down from $521.43.⁸ The KiwiSaver year runs to 30 June, so anyone who started work part-way through the year or took parental leave can fall short of the $1,042.86 threshold and miss part of the top-up. A KiwiSaver review checks this before the cut-off.

Withdrawals at 65: turning a balance into weekly income

Once you turn 65 (and have been in KiwiSaver at least five years if you joined after 65), you can withdraw your KiwiSaver however you like, in one lump sum, in chunks, or as a regular "pay cheque" that lands in your account each fortnight to sit alongside NZ Super. The regular-drawdown approach is common, because it mirrors a salary and keeps the rest of the balance invested and growing.

The fund you draw from is not a detail. Two things quietly decide how long your money lasts:

Make sure your PIR is right, because it caps the after-tax return funding your gap:

(Source: PIE income thresholds, aligned to IRD bands.¹⁰) For many retirees living mainly on NZ Super plus modest drawdown, the correct PIR is 17.5%, not the 28% they were on while working, so this is worth checking the year you stop earning a salary.

A KiwiSaver advice session covers fund choice, drawdown rate and PIR together, because changing one without the others rarely gives you the income you wanted. Comparing funds across the major NZ KiwiSaver providers, rather than a single in-house product, means the fund chosen is the one that fits your gap.

Key risks: inflation, longevity and renting in retirement

Three risks can blow out a gap you thought you had handled.

Inflation. NZ Super is adjusted each year, but your "choices" spending, travel, dining, healthcare, can rise faster than the index. A gap of $235/week today is a bigger gap in real dollars in 15 years. Staying partly invested in growth assets through retirement is how you keep up, rather than parking everything in cash.

Longevity. Plan to 85 and live to 92 and you have a seven-year hole at the end, exactly when health and care costs peak. With a 65-year-old man expecting ~26 more years and a woman ~28,¹² which carries the average retiree into their early 90s, under-planning your lifespan is a common drawdown mistake.

Renting in retirement. Every Massey metro figure assumes a fairly settled housing position. If you are renting at 65, your gap is materially larger and far more exposed to inflation, because rent rises while NZ Super only catches up once a year. Renters need a bigger KiwiSaver balance, not a smaller one.

How Smiths Financial sizes and funds your gap

The question behind every retirement review is the same: what is your number, and is your KiwiSaver on track to hit it? A free 30-minute review covers four steps:

1. Size the gap. Your real costs (not a table average) against your 2026 NZ Super entitlement, single or couple.

2. Set the target. Turn that weekly gap into a lump-sum goal across a realistic, long, retirement.

3. Check the engine. Confirm your KiwiSaver fund, fees and PIR are actually pulling toward that target, and that you are not leaving the government contribution on the table before 30 June.

4. Plan the drawdown. Map how your KiwiSaver pays you a fortnightly top-up alongside NZ Super, without running dry.

Frequently asked questions

What is the retirement income gap in NZ? It is the weekly difference between what NZ Super pays you and what your retirement actually costs. In 2026 NZ Super pays a single about $555/week and a couple about $854/week combined,¹² while a no-frills metro single spends about $705/week,⁵ leaving a gap of roughly $150 to be funded from KiwiSaver or other savings.

How much does NZ Super pay in 2026? From 1 April 2026, after tax on the M code, a single person living alone gets $1,110.30 per fortnight (about $555/week), and each member of a qualifying couple gets $854.08 per fortnight, $1,708.16 combined (about $854/week combined).¹²

How much do I need saved to close the gap? It depends on your gap. Massey's 2025 modelling puts a metro couple wanting a "choices" lifestyle at around $1.14 million ($1,142,000), and a provincial choices couple at around $446,000.⁶ A no-frills provincial single, whose gap is only about $26/week against 2026 Super (Massey published $42.33 on the older Super base),³ needs far less.

How does KiwiSaver help once I'm retired? From 65 you can withdraw your KiwiSaver as a lump sum or, more commonly, as a regular fortnightly payment that sits on top of NZ Super. Keeping the balance invested in an appropriate fund means it can keep earning while you draw it down. Fund fees, returns and your PIR all affect how long it lasts.¹³

What PIR should I be on in retirement? Your PIR is based on your income: 10.5% up to $15,600, 17.5% from $15,601 to $53,500, and 28% above that.¹⁰ Many people who retire stay stuck on 28% from their working years when 17.5% is now correct, so it is worth re-checking the year your salary stops.

Is the government KiwiSaver contribution still worth chasing? Yes, though it was halved in Budget 2025. You now need to contribute $1,042.86 of your own money in the KiwiSaver year to receive the maximum $260.72 top-up (down from $521.43), and earners over $180,000 are no longer eligible.⁷⁸
