How to Invest $1 Million in New Zealand
Our guide explains how to invest a $1 million lump sum in New Zealand - whether it's come from a business sale, an inheritance, selling a property, or a lifetime of saving. We cover what to do before you invest a cent, how to build a diversified and tax-smart portfolio, whether to invest it all at once, and the mistakes that cost people the most.

Summary
Two instincts tend to take over, and both are often mistakes:
Know This: $1 million is a lot, but it isn't infinite. Drawn down sensibly, it produces a comfortable income, not unlimited spending - at a sustainable rate, it might generate in the region of $40,000 to $60,000 a year, on top of NZ Super (if you're eligible to receive it). Thinking of it as an income-producing asset, rather than a windfall to spend, is the mindset that makes it last. Our guide, How to Turn $500,000 Into a Retirement Income in New Zealand, explains how the income side works.

- $1 million can arrive all at once - the sale of a business, an inheritance, the proceeds of a property disposal, or simply the moment KiwiSaver and savings nudge up to seven figures after consistent investing. The question that follows is daunting - what do I actually do with it?
Two instincts tend to take over, and both are often mistakes:
- The first is to rush - to feel the money must be "put to work" immediately, often into whatever someone has just recommended.
- The second is the opposite - to freeze, leave it sitting in the bank, and let inflation quietly erode it for years.
- It's widely accepted that, for most people, the right path runs between the two - a calm, deliberate plan that gets the money into a diversified, low-cost, tax-smart portfolio matched to your timeframe and goals.

MoneyHub Founder Christopher Walsh shares his observations:
"I was contacted a couple of years ago by the surviving adult child who had inherited their parent's estate, around five million dollars. The nature of their email was to raise alarm about a financial adviser's behaviour who was insistent on investing it asap, and all into two funds run by one manager. Unfortunately, this fund manager was known for paying generous trail commissions to advisers. Of course, I'm not a financial adviser, but I explained that there is no need to rush any decision and explained to them the reasons the financial adviser may have such enthusiasm for making the investment. I'm suspicious that the adviser may read death notices as a source of leads, but of course I have no proof of that. However, what's important is that the reader understood the information, which led them to make an informed decision about what to do. If this is you, please don't rush - the best decisions take time". |

What to Do Before You Invest a Single Dollar
The temptation with a large sum is to act fast - please resist doing so - a few weeks spent getting your foundations right are worth far more than a quick decision you can't undo. MoneyHub receives too many emails from New Zealanders who have rushed into an investment without fully considering it. Our suggested considerations include:
- Parking the funds somewhere safe and boring first: A call account, cash fund or short-term deposit can be the right home while you make a plan. Money sitting in cash for a few weeks costs you almost nothing; a rushed investment can cost you a great deal.
- Clear expensive debt: Paying off a credit card or high-rate loan is a guaranteed, risk-free return equal to the interest rate. Our guide to credit card debt explains how expensive (and common) this kind of debt can be. A mortgage is not as clear - clearing it buys certainty and peace of mind, but you may earn more by investing; that's a genuine personal call. Our mortgage repayment calculator offers further insights you can test with your situation.
- Set aside an emergency buffer: Keep enough in cash to cover the unexpected and any spending you'll need in the next two to three years, so you're never forced to sell investments at a bad time. Too few New Zealanders have emergency funds, but allocating funds to establish one gives you a lot of financial freedom - our guide to emergency funds is worthwhile reading.
- Decide the money's job and timeframe: Is this your retirement income, a legacy for your children, or capital you won't touch for 20+ years? The answer drives everything that follows - money you need in three years is invested completely differently from money you won't touch for two decades.
- Be on high alert for anyone who suddenly wants to help: A large sum attracts attention. While it's always good to trust people, we suggest being deeply sceptical of unsolicited "opportunities," guaranteed returns, and anything with an urgent pitch. Our guide, New Zealand Investing Mistakes, explains pitfalls in detail, and the same traps apply to any windfall.
Warning: The Depositor Compensation Scheme only protects $100,000 per bank - $1 million parked in one place is mostly uncovered
Bank failures in New Zealand are rare, but the entire point of parking money is to take zero risk. Sensible options while you decide include:
- Since 1 July 2025, the government's Depositor Compensation Scheme (DCS) protects depositors up to $100,000 in the unlikely event their bank or other licensed deposit taker fails.
- The limit is per depositor, per institution - so if you hold multiple accounts with the same bank, your total protection is still capped at $100,000.
- This means if you invest $1 million in one bank while you plan, $900,000 of it sits outside the safety net.
Bank failures in New Zealand are rare, but the entire point of parking money is to take zero risk. Sensible options while you decide include:
- Spreading it across several licensed deposit takers: If two or more banks failed, you'd be protected up to $100,000 at each one. Joint accounts help - each account holder is covered up to $100,000, so a couple holding money jointly is effectively protected up to $200,000 per institution.
- Know what isn't covered: The DCS covers standard banking products - transaction, savings, notice and term deposit accounts. Managed funds, including cash PIE funds, are generally not DCS-protected (they are protected differently, through custodial structures). Trust accounts are capped at $100,000 per trust, regardless of how many trustees are named - relevant if your windfall is sitting in a family trust or estate account.
- The Reserve Bank publishes a list of all deposit takers offering DCS-protected deposits, and every deposit taker must list its protected products on its website. Our DCS guide has further details.
Warning: Scammers specifically target New Zealanders with lump sums to invest
Please protect yourself with these checks:
Know This: The other threat to a windfall isn't criminals - it's people you know. Loans to family, a relative's business "opportunity", or pressure to gift money early are among the most common ways lump sums quietly shrink. None of it is a scam, which is exactly why it's hard to say no.
Please decide your policy before anyone asks ("it's all committed to fixed investments" is a commonly used answer we suggest considering), document any family loans formally, as if they were a bank's, and never lend or guarantee more than you could afford never to see again.
- The FMA has repeatedly warned about a scam pattern aimed at exactly this situation - someone with a large sum searching for a safe home for it.
- It typically starts when the victim sees an advertisement or visits a fake comparison website, where they're prompted to enter their contact details.
- These phony comparison sites often appear as paid, sponsored links in search results, sitting alongside legitimate sites, and exist purely to harvest personal details for criminals selling fake investments.
- The victim then receives a call or email from someone claiming to be an investment adviser from a well-known firm, offering an investment opportunity - usually with a well-known New Zealand bank - and may be given detailed but fraudulent investment documentation. The offer is typically a term deposit or bond paying just enough above market rates to be tempting.
- MoneyHub has been contacted several times by would-be victims of this scam; in every instance, we warned them and they cut off contact. But not everyone emails us to ask, and reported losses have been significant. We suspect many more have been defrauded and stayed silent out of shame.
Please protect yourself with these checks:
- Verify independently: Call the bank or firm on the number from its official website - never a number you were given by the caller or in an email.
- Check the FMA's list of warnings and alerts before moving any money. Be aware that scammers may tell you an FMA warning is incorrect, out of date, or about someone else - the FMA publishes warnings precisely because it has serious concerns.
- Treat urgency as a red flag: Language like "expires soon" or "last chance today" is a tactic to pressure you into acting quickly. No legitimate term deposit needs a decision within hours.
- Get a second set of eyes. Speak with someone you trust - a friend, family member or adviser - before transferring anything.
- If it's already happened, contact your bank immediately - they have processes to deal with fraud - and report it to the FMA.

How to Think About a $1 Million Portfolio
Once your foundations are set, a sound portfolio is built from three simple building blocks, mixed to suit your timeframe and preferences:
Know This: The right mix of these depends mostly on your age and how soon you'll spend the money - which is the subject of our guide to Asset Allocation by Age. As a rule, the longer your investment horizon, the more growth you can hold.
Important: The home-bias trap is alive and well in New Zealand
Diversification beats concentration
- Growth assets (shares and share funds) - this is the engine of long-term returns. Over long periods, shares have historically outpaced everything else, which is why it's arguable that even retirees usually need a meaningful allocation.
- Income and defensive assets (bonds and bond funds) - lower returns, but steadier; they cushion the portfolio when shares fall.
- Cash (savings and term deposits) - safety and near-term spending money, kept out of the market's reach.
Know This: The right mix of these depends mostly on your age and how soon you'll spend the money - which is the subject of our guide to Asset Allocation by Age. As a rule, the longer your investment horizon, the more growth you can hold.
Important: The home-bias trap is alive and well in New Zealand
- We believe most New Zealanders hold far too much of their wealth in local assets - the family home, local rental(s), and a portfolio tilted heavily towards New Zealand and Australian shares.
- New Zealand is a tiny slice of the world's markets, so concentrating here leaves you exposed to one small economy.
- A $1 million portfolio is the point to fix this deliberately - you can consider holding the bulk of your growth assets globally. However, if you decide to do so, it's not without tax consequences - see the tax section below.
Diversification beats concentration
- The single biggest risk with a large sum is putting too much in one place - one company, one rental property, one "sure thing."
- Spreading across hundreds or thousands of holdings around the world turns $1 million from a fragile bet into a resilient portfolio.
What $1 Million Could Become - and What Doing Nothing Costs
The table below shows how $1 million could grow at different net annual returns (after fees and taxes, no withdrawals). Returns are never this smooth in practice - markets rise and fall along the way - but the long-run maths is what matters:

| Net annual return | 10 years | 20 years | 30 years |
|---|---|---|---|
| 3% | $1,340,000 | $1,810,000 | $2,430,000 |
| 5% | $1,630,000 | $2,650,000 | $4,320,000 |
| 7% | $1,970,000 | $3,870,000 | $7,610,000 |

Know This: Inflation runs the same compounding in reverse.
Know This: Inflation runs the same compounding in reverse.
- At 2.5% inflation, you need roughly $1.28 million in 10 years and $1.64 million in 20 years just to preserve the purchasing power of $1 million today.
- Left earning nothing, $1 million buys what about $780,000 buys today after 10 years, and about $610,000 after 20.
- "Doing nothing" with a lump sum feels safe, but it is a decision with a six-figure cost - inflation is often the quietest fee you'll ever pay.
Should You Invest It All at Once or in Stages?
This is the question almost everyone with a lump sum asks. There are two approaches:
Research - including a well-known study by Vanguard - has generally found that investing a lump sum immediately beats drip-feeding it about two-thirds of the time, simply because markets rise more often than they fall, so time in the market usually wins. On the numbers alone, investing it all now is more often the better call. However, if you're not comfortable with doing that but want to invest within one month or less, you may want to invest the amount in buckets - perhaps in fifths over five days, or into tenths over two weeks.
Staging exists to manage regret and sequencing risk. There is a very real chance that you invest your $1 million the week before a market crash, and the emotional damage is not insignificant, even if markets usually recover quickly. For a large and irreplaceable sum, a middle path is often popular: invest a good portion now and stage the rest over the following 6 to 12 months. You give up a little expected return for a lot of peace of mind - and peace of mind is what keeps people invested.
- Lump sum: You invest the whole amount now, in line with your target mix.
- Staging (dollar-cost averaging): You drip-feed money into the market over several months, a year, or two. Our guide to dollar-cost averaging has more details.

Our View: For most people with a large lump sum, the best approach is to invest a meaningful portion straight away and stage the remainder over the next 6 to 12 months on a fixed schedule. It captures most of the "time in the market" benefit while protecting you from the gut-punch of bad timing on your whole sum at once.
Where You Can Invest It - Funds vs ETFs vs Shares vs Cash
You have four main ways to hold your investments, and for a portfolio this size, the choice genuinely matters - on cost, tax, and flexibility:
Our View: For a larger portfolio, a spread of holdings (e.g. a genuine portfolio rather than a single all-in-one fund) gives you more flexibility, especially once you're drawing an income. This means, for many people, selecting some funds and tax-efficient ETFs, and keeping an allocation in interest-earning cash investments such as a term deposit. Our guide to popular managed funds is a helpful starting point.
- Managed and diversified funds - the simplest option. A single low-cost diversified fund can hold your entire growth-and-income mix in one product, professionally managed and rebalanced for you.
- ETFs (exchange-traded funds) - often the lowest-cost way to own a global index, bought through an investment platform.
- Direct shares - holding individual companies yourself; more control, far more effort, and easy to get wrong.
- Cash - investing using term deposits, savings accounts and similar - any investment will usually have a cash element.

Our guide to popular managed funds is a helpful starting point.
Tax-Efficient Investing to Maximise Your $1 Million Investment
At this size, tax efficiency is essential because the sums involved are significant. We suggest considering the following essentials:
- Use PIE funds and get your PIR right: Income from a Portfolio Investment Entity is taxed at your Prescribed Investor Rate, which is capped below the top personal income tax rate - so a PIE is often more tax-efficient than holding the same money directly. On a $1 million portfolio, the wrong PIR can cost you meaningfully. See our guide to Tax on Investments and Savings.
- Be aware of the FIF rules on direct overseas shares and ETFs: Holding global shares directly, above the Foreign Investment Fund threshold, brings you into the FIF regime - while holding the same global exposure through a PIE fund sidesteps that complexity. This matters more at $1 million, where you're more likely to cross the threshold. See our guide to Tax-Efficient Investing.
- There's no general capital gains tax in New Zealand: The bright-line test on residential property is the main exception. It's one reason a share portfolio can be more tax-friendly than a rental for a retiree.
DIY vs a Financial Adviser or Wealth Manager
$1 million is a significant sum. While you can DIY your investments, for many people, advice is worth considering because the stakes and the complexity both rise.
You may not need ongoing advice if your situation is simple - you plan to invest in one or two diversified funds and have a clear plan (and the discipline) to stick to it. Plenty of New Zealanders manage seven-figure portfolios perfectly well with a mix of robust managed funds and perform an annual review to make sure their investments remain aligned with their plan.
Advice is usually worth considering when the picture gets complicated - a business sale, a rental property sale, a trust, blended-family estate planning, or simply the wish to hand the ongoing management - and the decision-making - to someone else. The value is as much in behaviour and structure as in picking investments.
Important: If you do seek advice, understand exactly what you're paying and what you're getting first - fees compound, and on $1 million, a percentage point a year is a large sum over a retirement, as the tables below show.

Understanding the Investing Mistakes New Zealanders Make Over and Over
While every investment decision is unique, we list the themes of investment mistakes that are unfortunately not uncommon:
- Leaving it in cash for years: The most common error with a windfall is that it feels safe, but inflation steadily erodes a million dollars left idle.
- Home bias: Piling into New Zealand property and NZX-listed shares because they're familiar, leaving you exposed to one small economy. Our guide to investment property risks has more specifics.
- Over-concentration: Putting too much into a single company, rental, or "opportunity." Diversification needs to be at the heart of everything you do.
- Paying too much in fees: On $1 million, fees are real money. Many wealth and financial advisers charge 1% as an ongoing advice fee, but then you may also have to pay annual custodian fees (up to 0.3% of your investment), GST and brokerage to buy/sell ETFs. You may also be in funds that are not tax-efficient, such as Australian (AUD)- or UK (GBP)- based funds. Check what you're paying - this means every layer of it.
- Lifestyle inflation: Spending the windfall down faster than you realise, with nothing structural to show for it.
A Sample Portfolio (Illustrative)
This is a simplified illustration of how a diversified $1 million portfolio might be split for someone around 60 with a long horizon. It is not a recommendation - your right mix depends on your age, goals and risk tolerance - our asset allocation by age guide has more details.
Building Block |
Example Share of $1,000,000 |
Role |
Global shares (via a PIE fund) |
$500,000 |
The main growth engine, spread worldwide |
New Zealand and Australian shares |
$150,000 |
Growth, plus imputation credits on NZ dividends |
Bonds / income funds |
$250,000 |
Stability, and a cushion when shares fall |
Cash and term deposits |
$100,000 |
Buffer and near-term spending, out of the market |
Important: The exact percentages matter far less than the principles behind them: diversified, mostly global, low-cost, tax-aware, and matched to your timeframe.
What Fees Really Cost on a $1 Million Portfolio
- Fees compound in reverse - every dollar you pay in fees is a dollar that stops earning returns for the next 20 years.
- The table below shows $1 million invested for 20 years, assuming a 5.5% p.a. return before fees (illustrative only, before tax, no withdrawals).
- The gap between the cheapest and most expensive setup is $878,000 - almost 90% of your original investment, lost to fees.
| All-in annual costs | Typical setup | Value after 20 years | Cost vs lowest-fee option |
|---|---|---|---|
| 0.30% | DIY with low-cost index funds and ETFs | $2,756,000 | - |
| 0.80% | Actively managed diversified funds, no adviser | $2,506,000 | $250,000 |
| 1.60% | Full-service: ~1% advice fee + fund fees + custody + GST | $2,149,000 | $607,000 |
| 2.30% | High-cost wealth management: 1% advice fee + 1% fund fees + brokerage, admin and custody | $1,878,000 | $878,000 |
Frequently Asked Questions
Is $1 million enough to retire on in New Zealand?
For a mortgage-free household, comfortably so. On top of NZ Super, a sensibly invested $1 million can fund a very comfortable retirement. Whether it's "enough" depends on your lifestyle, housing and health - model it in our Retirement Calculator.
How much income will $1 million produce?
Drawn sustainably, roughly $40,000 to $60,000 a year, depending on how you draw it down - on top of NZ Super, with the higher end involving a gradual drawdown of capital rather than preserving it.
Should I invest it all at once or gradually?
The evidence favours investing it all at once most of the time, because markets usually rise. But staging the money over 6 to 12 months is a sensible way to manage the risk of bad timing on a large, irreplaceable sum. A blend of the two suits most people.
Where should I keep $1 million while I decide?
The best approach is usually somewhere safe and liquid - a call account, cash fund, or short-term deposits. The goal is to protect it, not to earn a return, while you make a plan.
Do I pay tax on investing $1 million?
You pay tax on the income and earnings (through PIE/PIR or your normal rate), but New Zealand has no general capital gains tax. Getting your PIR right and managing FIF on any direct overseas holdings are the two things that matter most at this size.
Should I use a financial adviser for $1 million?
Often worth it, especially if your situation is complex (a business sale, rentals, trusts, estate planning) or you'd simply rather not manage it yourself. Understand the fees first, and make sure any adviser is licensed.
