Selling Your Business as a Retirement Plan in NZ: Why Owners Need KiwiSaver Too (NZ, 2026)

A business sale is a fragile retirement plan: 74% of NZ enterprises have no employees and may not sell. Why owners need KiwiSaver and investments alongside, with a diversification plan and checklist.

Ask a self-employed New Zealander what their retirement plan is and you'll often get a version of the same answer: "I'll sell the business." It feels logical. You've poured decades, capital and most of your savings into it, so why not let it fund the next chapter? The trouble is that using selling your business as your retirement plan in NZ leans the whole thing on a single, illiquid, hard-to-value asset — the most concentrated retirement plan there is. And it's also the most common: New Zealand has 617,330 enterprises, and 74% of them have no paid employees ¹ — owner-operated businesses where the value is bound up in one person.

This guide explains why a sale is a fragile plan on its own, the four risks that can derail it, and how a modest, diversified pot of KiwiSaver and investments alongside the business turns "I hope it sells" into "I'm fine either way".

TL;DR: A sale should not be your only retirement plan. 74% of NZ enterprises have no paid employees ¹ — owner-dependent businesses that are slow to sell and easy to undervalue. Building KiwiSaver and investments alongside the business gives you a liquid, diversified pot worth up to $260.72 a year in government contributions ², independent of finding a buyer.

Is selling my business a reliable way to retire?

On its own, no. A sale can be a wonderful part of a retirement plan — but as the whole plan it asks one asset to do too much. With 74% of New Zealand's 617,330 enterprises having no paid employees ¹, the business is the owner: their time, skills and relationships. That value is difficult to transfer to a buyer and difficult to bank in advance.

A diversified investor who loses 20% in a bad market still has the other 80% working, and time to recover. An owner whose entire retirement is the business has no such buffer. If the sale falls through, comes in low, or doesn't happen on schedule, there is no second engine. The fix is not "don't sell" — it's "don't only sell". Build a separate, liquid pot in parallel so the business sale becomes the upside, not the lifeline.

The four risks of relying on a sale

A business sale can fail you in four distinct ways. Most owners are exposed to at least two of them, and the risks compound rather than cancel out.

Timing risk

You don't get to choose the year you need to retire. Health, burnout, a family event or simply running out of energy can force the question early — and the market for small businesses moves in cycles. Selling into a downturn, a credit squeeze or a sector slump can knock years of value off the price. A salaried saver can delay drawing down for a year or two and let markets recover; an owner who has to sell in a soft market crystallises the loss permanently. A good sale also often takes 6–24 months to negotiate and settle, so "I'll sell when I'm ready" can become "I'll sell whenever a buyer turns up".

Valuation risk

Owners routinely overestimate what their business is worth. Buyers pay for transferable, documented, recurring profit — not for goodwill that walks out the door with you. If the business depends on your relationships, your technical skill or your seven-day weeks, a buyer discounts heavily or structures the deal as an earn-out, paying you over several years only if the business keeps performing without you. That turns a clean "sell and retire" into "stay involved and hope". Multiples shift with interest rates and sector sentiment too, so the number in your head from five years ago may bear no relation to today's offer.

No-buyer risk

This is the one owners least like to confront. For a small, owner-operated business — the 74% with no staff ¹ — there may simply be no buyer at any sensible price. The skills don't transfer, the customer relationships are personal, and a competitor would rather poach your clients than pay for them. Plenty of trade and professional-services businesses don't sell at all; they wind down, and the "retirement asset" turns out to be a job that ends when the owner stops. A succession plan that assumes a buyer exists is a hope, not a plan.

Concentration risk

Even if timing, price and a buyer all line up, the deeper problem is that everything you own is one asset, in one industry, in one country, exposed to one set of risks — your health, your sector, one regulatory change, one large client leaving. Standard portfolio theory says you reduce risk by spreading across uncorrelated assets. An owner whose home, income and retirement are all tied to the same business has the opposite: maximum concentration at the exact life stage when you can least afford a shock.

How does KiwiSaver diversify you away from a single asset?

KiwiSaver is the simplest, cheapest way for an owner to build a second asset that behaves nothing like the business. It's liquid at 65, professionally diversified across thousands of global companies, government-supported, and it keeps compounding whether or not anyone ever wants to buy your business.

Yet the self-employed are dramatically under-using it. Only 44% of self-employed New Zealanders actively contribute to KiwiSaver, versus 78% of employees ³ — less than half the rate. And 41% of self-employed members receive no government contribution at all ³, usually because irregular income means they never reach the annual threshold. That is a guaranteed return going unclaimed, year after year, by exactly the people whose retirement is most concentrated.

For employees, contributions, the employer match (paid on top of salary, and itself taxed via Employer Superannuation Contribution Tax, or ESCT) all happen automatically through payroll. As an owner, nobody does it for you — which is precisely why it gets skipped. The government contribution is the most generous deal in the system: contribute at least $1,042.86 between 1 July and 30 June and you receive the maximum $260.72 government top-up ². Budget 2025 halved that match from 1 July 2025 — down from 50c to 25c per dollar, with the maximum cut from $521.43 to $260.72 ⁴ — and added a $180,000 income cap above which you no longer qualify ². That cap is on taxable income, so for most owners it rarely bites. It's worth less than it was, but for a self-employed person paying in voluntarily it's still a guaranteed, risk-free return that the business sale can never match.

If you've had a lean year and haven't reached the threshold, you can make a voluntary lump-sum top-up to $1,042.86 by 30 June to claim the full contribution — note that employer contributions and past government contributions don't count toward it ². Self-employed members often fall short of the full government contribution without realising it, because no payroll system tops them up the way it does for employees. A voluntary online top-up before 30 June fixes it. (Bear in mind KiwiSaver locks up until 65, with limited exceptions such as a first-home withdrawal — so it's one piece of the plan, not all of it.)

What does a balanced owner's retirement plan look like?

The goal isn't to stop investing in the business — it's to stop the business being the only thing you own. A balanced owner's plan runs two engines in parallel: the business (high return, illiquid, concentrated, uncertain timing) and a diversified financial pot (lower headline return, liquid, spread across the world, predictable).

Figure: Concentrated vs diversified owner retirement (Smiths adviser framework; IRD / Stats NZ ¹²)

The scale of the alternative is real, not theoretical: total KiwiSaver funds under management have reached $123.1 billion, with an average balance of $36,349 per member ⁵. That's a national habit of building a liquid retirement asset — one the self-employed are largely sitting out.

How much should you hold outside the business?

There's no single right number, but the principle is straightforward: enough outside the business that, if the sale delivered nothing, you would still have a viable retirement. A common adviser starting point is to aim for a diversified pot that could cover your essential living costs in retirement on its own, then treat any sale proceeds as a bonus that funds the extras — travel, helping the kids, a better house.

Where you start depends on how close you are. The cost of building the pot rises steeply the longer you leave it, because compounding does most of the work in the early decades.

(The bands above are an adviser rule of thumb, not a regulatory standard.) A non-KiwiSaver investment account matters for owners because many retire — or want the option to — before 65, when KiwiSaver locks up. A managed fund or PIE outside KiwiSaver gives you that flexibility. Watch your Prescribed Investor Rate (PIR) on these: it's 10.5%, 17.5% or 28% depending on income (taxable income of $15,600 or less and total income $53,500 or less is 10.5%; up to $78,100 total is 17.5%; above that is 28%) ⁶. Owners with a lumpy income often sit on the wrong PIR and quietly overpay tax for years.

Starting now: the cost of leaving it to the last few years

Many owners plan to "get serious about investing once the business is established" — and then it never quite is. The problem is that compounding rewards time far more than amount. A dollar invested at 40 has 25 years to grow; the same dollar at 60 has five. Leaving the diversified pot to the final few years before sale means trying to build in five years what should have taken twenty-five, with none of the compounding tailwind.

It's getting harder, not easier, for the self-employed. After Budget 2025's changes, 24% of sole traders said they would reduce their KiwiSaver contributions, and a further 6% would stop entirely ³. That's a third of sole traders pulling back from the one diversified asset most of them already under-fund — exactly the wrong direction for a group whose retirement is so concentrated.

Fees matter over these long horizons too, and this is where an independent review earns its keep. Consider a growth fund on a typical balance. Across the Sorted Smart Investor growth-fund cohort the average total fee runs to about 1.07%, or $319.70 on a $30,000 balance, while low-fee index providers such as Simplicity charge as little as 0.25% — about $75 on $30,000 [Provider data]. On fundcompare.co.nz, the cheapest growth fund in the cohort sits at that ~0.25% level, against a peer median of 1.13% across the 67 funds in the cohort [Provider data]. Over a 25-year run, that fee gap alone compounds into tens of thousands of dollars — money that should be funding your retirement, not the fund manager's.

How a low-fee growth fund stacks up

Source: Sorted Smart Investor and MoneyHub for Simplicity Growth (prior-year returns 5.83% to Mar 2025, 16.04% to Mar 2024). For context, the FMA's sector benchmark for balanced funds — a lower-risk category than growth — was a 5.7% annual and 5% three-year average; we cite it as a balanced-fund reference point, not a like-for-like comparison to a growth fund's 6.01% ⁵. Returns are net of fees, before tax; past performance is not a guide to the future and these figures age quickly, so check current Sorted/MoneyHub data before acting. Across the whole system, KiwiSaver members paid $868.5 million in fees last year — about 0.7% of funds under management ⁵ — so where you sit on that fee spectrum is not a rounding error.

Simplicity is one option among several strong providers — Milford, Generate, Booster, Kernel, Fisher Funds and ANZ all run credible growth funds at different price points and styles. The right one depends on your timeframe, temperament and whether you value low cost or active management. That's the conversation a KiwiSaver advice session is for.

Your owner's retirement diversification checklist

Five steps that move you from "I'll sell the business" to a plan that holds up if you don't.

01 — Start (or restart) KiwiSaver contributions. If you're self-employed and not contributing, you're in the under-saving 44% ³. Set up a voluntary contribution today, however small.

02 — Capture the full government contribution every year. Pay in at least $1,042.86 by 30 June to claim the $260.72 top-up; top up with a lump sum if a lean year left you short ². Don't be one of the 41% who get nothing ³.

03 — Check your fund and your fees. Make sure your KiwiSaver risk level matches your timeframe, and that you're not paying cohort-average fees of ~1.07% when low-cost growth options sit near 0.25% [Provider data]⁵.

04 — Build a liquid pot outside KiwiSaver. A managed fund or PIE you can access before 65 gives you the flexibility to retire — or step back — on your own schedule, not the buyer's. Set your PIR correctly ⁶.

05 — Get an honest, independent business valuation. Replace the number in your head with a real one, and plan succession early so the sale becomes upside rather than the entire plan.

The annual review that keeps both plans honest

An annual review tests both engines: is the diversified pot on track, are you capturing the full government contribution, is your fund and PIR right, and is the business valuation grounded in what a buyer would actually pay? Reviewing this each year, with an independent adviser, keeps the sale as the bonus rather than the bet.

You don't have to choose between the business and a backup plan — you can build both. Start with our retirement planning service, run the retirement calculator, or book a free review.

Frequently asked questions

Is selling my business a safe way to fund retirement?

Not on its own. A business is illiquid, hard to value and may not sell at all — 74% of NZ enterprises are owner-operated with no staff ¹, which makes them slow to transfer. Treat a sale as the upside, and build a separate diversified pot (KiwiSaver plus investments) that funds retirement even if the sale disappoints.

How much KiwiSaver can a self-employed person get from the government?

Up to $260.72 a year. You need to contribute at least $1,042.86 between 1 July and 30 June, and your taxable income must be under the $180,000 cap ² — a cap that rarely bites for most owners. Budget 2025 halved the match to 25c per dollar from 1 July 2025 ⁴, but it's still a guaranteed return no business sale can match.

Why do so few self-employed people contribute to KiwiSaver?

Because nobody does it for them. Employees get automatic payroll deductions and an employer match; owners have to set it up themselves, so it gets skipped. Only 44% of the self-employed contribute, versus 78% of employees, and 41% of self-employed members receive no government contribution at all ³.

Should I keep reinvesting in my business or diversify into KiwiSaver?

Both. Reinvesting can grow the business, but it deepens your concentration risk. Diverting even a modest, regular amount into a diversified fund builds a second asset that behaves differently from the business and is liquid when you need it. The right split depends on your timeframe and how dependent the business is on you personally.

What's the difference between KiwiSaver and a regular investment account for an owner?

KiwiSaver attracts the government contribution but locks up until 65 (with limited exceptions, such as a first-home withdrawal). A non-KiwiSaver managed fund or PIE has no government top-up but can be accessed anytime — important if you might retire or step back before 65. Many owners use both, and should check their PIR (10.5%, 17.5% or 28%) on each ⁶.

How early should I start planning my business exit?

The earlier the better — compounding rewards time far more than amount, and a good sale typically takes 6–24 months to negotiate. Aim to have the diversified pot well underway 10–20 years out, and an honest independent valuation in hand 5+ years before you intend to sell.
