Retiring With a Mortgage or Renting in NZ (2026): How It Changes Your Plan

The standard retirement numbers quietly assume you own your home, mortgage-free. If you'll still be renting or paying a mortgage at 65, your real target is far higher. Here is how much more, and what to do about it.

Almost every "how much do I need to retire" article you'll read in New Zealand is built on one quiet assumption: that you'll own your home outright by 65, with no mortgage and no rent. That assumption sits underneath the Massey University guidelines, the Sorted calculators, and most provider tools. It is also becoming less true every year. If you'll still be renting or still carrying a mortgage when you stop work, your real savings target is materially higher, and the standard numbers will undershoot you badly.

This guide shows you, in dollars, how much extra you need, why the guidelines assume a paid-off house, and how to rebuild your KiwiSaver plan around the reality of your housing.

TL;DR

TL;DR: New Zealand's headline retirement numbers (Massey's $705/week "no-frills" for a single metro retiree) assume you own your home mortgage-free.¹² If you'll still pay rent or a mortgage, add that housing cost on top of your savings target, often $15,000–$25,000+ a year NZ Super won't cover. Budget the housing cost in, then size your KiwiSaver to it.

Why do most retirement guidelines assume a paid-off house?

The most-cited NZ retirement benchmark is Massey University's New Zealand Retirement Expenditure Guidelines. They publish a weekly spend for four lifestyles, but every figure is calculated for households living mortgage-free in a home they own.¹² AMP's plain-English summary of the 2025 guidelines says it directly: "these figures assume you're mortgage-free," and "if you're still paying off a mortgage, other debt, or rent, your retirement spending may be higher."¹

That matters because housing is the single largest line in most household budgets. Strip it out and the numbers look manageable. Leave it in and the picture changes completely. NZ Super is the floor everyone gets: from 1 April 2026 a single person living alone receives $555.15/week after tax (about $28,868 a year), and a qualifying couple gets $854.08 each per fortnight, or $427.04/week each ($854.08/week combined).⁴⁵ That floor was designed around the idea that your roof is already paid for.

Here is the problem: the mortgage-free assumption is steadily becoming a minority experience. Total home ownership has fallen from 75% in 1991 to about 60% in 2023, and is projected to reach 48% by 2048.¹³ The Retirement Commission projects that about 40% of retirees, roughly 600,000 people, will be renting by 2048.¹² Among today's over-65s, the mortgage-free rate has already slipped from 78% in 2007 to 72% in 2017, with roughly 12% still paying a mortgage and another 12% renting.¹⁴

A common situation: someone in their late fifties with a solid KiwiSaver balance runs the Sorted number and feels on track, without noticing the calculator assumed their mortgage would be gone by 65. The plan isn't wrong; the starting assumption is.

How much more do you need if you'll still be renting?

Start with the Massey 2025 weekly spend, then remember it does not include rent. You have to layer your housing cost on top.

Now add rent. A single retiree renting a modest one-bedroom flat at, say, $450/week needs that $450 on top of the $705 no-frills figure, because the $705 never included it. A mortgage-free single retiree already faces a roughly $150/week gap between NZ Super ($555.15/week) and the $705.34 no-frills lifestyle; $450 of rent is a separate, additional cost of about $23,400 a year that sits entirely on top of that pre-existing gap.

Over a 25-year retirement (65 to 90), rent doesn't stop. Even before allowing for rent increases, $450/week for 25 years is more than $585,000 of spending the standard lump-sum estimates never planned for. For context, Kernel Wealth's estimate of the lump sum a single person needs on top of NZ Super for a "choices" metro lifestyle, about $293,000 over a 25-year retirement (ages 65 to 90), explicitly assumes a mortgage-free owned home.³ A renter needs that plus a rent fund.

What if you'll still have a mortgage at 65?

A residual mortgage behaves like rent with a finish line, but the finish line is often years into retirement, and the burden is brutal while it lasts. Treasury and Retirement Commission research found that 80% of over-65 mortgagees spend more than 40% of their NZ Super on housing.¹⁵ When 40 cents of every Super dollar goes to the bank, the "no-frills" lifestyle Massey describes is simply not reachable on Super alone.

Worked example: a $180,000 mortgage at 65

Scenario: Dave and Lena reach 65 with a KiwiSaver and savings pot, but still owe $180,000 on a 6.0% mortgage with eight years to run. Repayments are about $2,360/month, roughly $545/week.

NZ Super alone ($854.08/week combined) does not even cover the no-frills spend; the gap is about $83/week before the mortgage, and roughly $628/week once the $545 repayment is added. To clear an extra $545/week for eight years, Dave and Lena need roughly $227,000 of repayments funded, on top of the lump sum the guidelines already assume. That is the gap the standard number hides.

Strategies: clear the mortgage, downsize, or budget rent in

There is no single right answer, but there are three coherent paths, and which one fits depends on your equity, income and risk appetite.

1. Clear the mortgage before 65. The cleanest outcome. Directing extra repayments in your fifties, structured around your offset and revolving-credit facilities, can shave years off the term. This is where debt structuring work pays off: a $180,000 balance cleared three years early is roughly $90,000 of repayments you never have to fund from savings. We model the trade-off between extra mortgage repayment and extra KiwiSaver contributions, because at certain ages one clearly beats the other.

2. Downsize or relocate at retirement. Selling a larger home, clearing the loan, and buying smaller (or moving from Auckland/Christchurch to a cheaper region) can convert a residual mortgage into a mortgage-free home plus a cash cushion. The risk is transaction costs and timing, you don't want to be forced to sell in a flat market.

3. Budget rent in as a permanent line. If ownership isn't realistic, the honest move is to treat rent as a fixed retirement cost and build a dedicated rent fund inside your plan. That means a larger KiwiSaver and investment target, and usually keeping a portion of your portfolio in growth assets for longer to outpace rising rents. This is the core of retirement planning for the growing group of New Zealanders who will rent.

Where does home equity release fit (and what are the risks)?

For homeowners who are asset-rich but cash-poor, a reverse mortgage (home equity release) lets you borrow against the house with no required repayments while you live there. In NZ this market is dominated by Heartland Bank, whose current rate is 7.75% p.a. variable (down from 7.99% set in August 2025).¹¹

The catch is compounding. Because you make no repayments, the interest is added to the balance and itself earns interest, monthly. At 7.75% a balance left untouched roughly doubles in under a decade. Borrow $100,000 at 65 and the debt can exceed $200,000 by your late seventies, steadily eroding the equity, and the estate, you leave behind. A reverse mortgage can be a sensible tool to fund care or essential costs late in retirement, but it is a last lever, not a substitute for saving. We'd always model it against downsizing first.

How does this change your KiwiSaver target?

If housing stays in your budget, KiwiSaver has to carry more of the load, and Budget 2025 made that harder. The annual government contribution was halved to $260.72 (you still need to put in $1,042.86 a year, about $21/week, to get the full amount), and there's now a $180,000 income cap above which you get nothing.⁶⁷⁸ The default contribution rate rises to 3.5% from 1 April 2026 and 4% from 1 April 2028.⁹ Less help from the government means more of the target has to come from you.

Before you change anything, model your own number: our retirement calculator lets you put your real rent or mortgage in and see the gap NZ Super leaves, rather than starting from a guideline that assumes neither.

Ready-reckoner: extra annual KiwiSaver/savings to fund your housing

\*Indicative only; ignores investment returns, inflation and rent increases, which a personalised model includes. The point is the order of magnitude: housing adds a six-figure layer to your target.

Two practical KiwiSaver levers for non-homeowners:

• Use a higher-growth fund for longer. Renters can't lean on a paid-off house, so the portfolio has to work harder and for longer. Providers like Simplicity, Milford, Generate, Booster, Kernel and Fisher Funds all offer growth and high-growth options; the right one depends on your timeframe and how much of your income you'll draw early. We compare across providers rather than defaulting you to your bank's scheme in a KiwiSaver review.
• Check your PIR. Retirees on lower incomes often sit on the wrong Prescribed Investor Rate and overpay tax. From 1 April 2025 the rates are 10.5%, 17.5% and 28%, set by your last two years' income, with the thresholds at $15,600 and $53,500 of total income (10.5% if income up to $15,600 and total income up to $53,500; 17.5% if total income up to $78,100; 28% above that).¹⁰ Getting it right saves tax over a 25-year drawdown.

How does Smiths plan retirement for non-homeowners?

We start by throwing out the mortgage-free default. The first thing we ask is what your housing looks like at 65 and beyond, then we build the spending plan from your actual rent or mortgage rather than a guideline that quietly assumes neither. From there we run the trade-off between paying down debt and topping up KiwiSaver, set the fund and PIR to match a longer drawdown, and stress-test it against rent rises and a longer-than-average life. If equity release ever makes sense, we model it against downsizing so you can see both. Then we review it every year, because rents and rates move.

Frequently asked questions

Do the Massey retirement guidelines include rent or mortgage payments? No. The Massey NZ Retirement Expenditure Guidelines are calculated for households living mortgage-free in a home they own, and exclude rent or mortgage repayments.¹² If you'll still be paying for housing, you must add that cost on top of the published weekly figures.

How much extra do I need to retire if I'm renting in NZ? As a rough guide, your rent is an extra cost the guidelines never counted. Rent of $400–$550/week is roughly $20,800–$28,600 a year, and over a 25-year retirement that can add $340,000 or more to your savings target on top of the standard lump-sum estimates.³ A personalised model factors in returns and rent increases.

Is it bad to retire with a mortgage in New Zealand? It's increasingly common, around 12% of over-65s still have one, but it puts real pressure on a fixed income.¹⁴ Treasury research found 80% of older mortgagees spend more than 40% of their NZ Super on housing.¹⁵ The priority is a clear plan to clear, downsize, or fund the remaining repayments.

Should I use my KiwiSaver to pay off my mortgage at 65? Sometimes, but not automatically. Clearing a 6% mortgage is a guaranteed return, while a growth fund may earn more over a long retirement. Whether to repay the loan or stay invested depends on the rate, the term left and your other income. We model both before recommending one.

Is a reverse mortgage a good idea for NZ retirees? It can fund essential costs late in retirement, but at Heartland's 7.75% variable rate the compounding interest erodes your equity fast, a balance can double in under a decade with no repayments.¹¹ We treat it as a last lever and model downsizing first.

What's the maximum KiwiSaver government contribution in 2026? $260.72 a year, halved in Budget 2025 from $521.43. You need to contribute $1,042.86 yourself (about $21/week) to receive the full amount, and members earning over $180,000 are no longer eligible.⁶⁷⁸
