How to Invest $1 Million in New Zealand

Perhaps the most important decision about investing a million dollars is when you will start to spend it. Whether the million came from an inheritance, a business sale, or years of saving, the building blocks are the same: global and New Zealand shares, fixed interest, property, and cash. How much goes into each asset class depends on your phase of life, other assets, attitudes towards risk and return, and personal aims, including when you will start to spend some or all of it. Someone who is retired and drawing an income holds the same blocks as someone with twenty years of salary ahead, in very different proportions. You will also usually structure your investments in a way or ways to keep tax and fees sensible. Once you separate any money you might need soon from the money you will not, most of the later decisions follow from that split.

The rest of this post assumes the million is yours to invest. It is also assumed any tax on the source is settled, any debt you wanted gone is repaid, and a reserve for emergencies is already accounted for rather than potentially being sourced from the investment portfolio.

It also helps to be realistic about what a million dollars now is. "A million dollars is a serious sum, though it is not the sum it once was," says Hayden Mulholland, private wealth manager at Become Wealth. "Occasionally we'll meet people who've amassed or come into such a sum, and think it can do more than they realise. A million dollars still deserves care, especially if it arrives all at once, because without wise decision making it might not last as long as many people expect."

Match each part of the million to when you will need it

A common starting point is:

• Money you will need within roughly five years usually sits in cash, term deposits, and short-dated fixed interest, where a bad year in share markets cannot touch it.
• Money you expect to need in the following five to ten years suits a mix of fixed interest and shares, tilted more conservative (i.e., more fixed interest) as the date approaches.
• Money you will not need for a decade or more is usually weighted towards shares and property, because over that horizon the swings along the way are the price of the return.

The boundaries between these objectives can move with how certain and how flexible each need is. If someone needs a house deposit due in two years it may be wise to take little or no risk, and leave the sum in cash. Regular retirement withdrawals are different, because they arrive gradually and can often flex. The amount kept out of share markets should reflect how certain and how soon each need is, rather than five full years of spending. Investment risk and return is judged the same way at every age. It comes down to how much you need to take to reach your goals, how much your finances can absorb, and how much you can tolerate watching the balance fall in a bad year.

Why leaving $1 million in cash is the expensive choice

Taking a few months to decide how to invest is sensible, and it is what we usually suggest. Leaving the money in cash for years while waiting to feel certain is where the cost sits. Even at 3 percent inflation, the top of the Reserve Bank's medium-term target band, a million dollars earning nothing buys about a quarter less after ten years. Interest closes some of that gap, and tax at your marginal rate opens it again. Over that horizon, doing nothing has a six-figure cost.

Asset allocation is the decision that matters most

Asset allocation is the biggest single driver of how a portfolio behaves. Ibbotson and Kaplan's study of pension and balanced funds found the policy allocation explained about 90 percent of the variation in a fund's returns over time. Costs, behaviour, security selection, and tax then decide how much of the result you keep. In our own practice, asset allocation is set using independent third-party research, because the decision carries too much weight to rest on any one person's market opinion.

Write the allocation down, with the reasons behind it. When markets fall, the written version is what you read before deciding whether anything has changed. Usually nothing has: the fall sits within the range the allocation was built to withstand, and the right action is none. Without a written allocation, a bad quarter is judged on how it feels, and that is when portfolios get redesigned at the worst possible moment.

Rebalancing keeps the allocation true over time. The assets which have risen most gradually become a larger share of the portfolio than intended, so rebalancing trims what has outgrown its target and adds to what has fallen behind. A workable rule is to rebalance annually on a set date, or whenever an asset class drifts beyond a set band from its target, whichever comes first.

Watch your concentration in particular. If you own a home, a rental property, a portfolio of NZX shares, and a job in the same economy, you have likely made the equivalent of one large bet several times over: centring everything on New Zealand. While this might seem familiar, it can result in you being over-exposed to New Zealand-specific risks such as an outbreak of mad cow disease, or a natural disaster. Plus, you might also be missing great offshore opportunities. Count the business you own, the employer you depend on, property, and even any inheritance you expect as part of the same exposure, because they all rise and fall with the same economy.

Alternative investments such as gold, private credit, cryptocurrency, art, wine, and collectibles sit outside this article. Some can hold a small place in a seven-figure portfolio; none is a substitute for the building blocks above, and most are hard to value or to sell.

A seven-figure sum also attracts invitations, and some will describe you as a wholesale investor. Wholesale offers do not carry the prescribed disclosure and regulatory protections of retail offers, which is why they can be made only to people who fall within a category the legislation defines. An eligible investor can self-certify through a certificate confirmed by an accountant, lawyer, or financial adviser, and a 2025 High Court decision confirmed an offeror may generally rely on it. Eligibility is not evidence the investment is suitable or sound, and a wholesale offer deserves proportionately more scepticism, whatever flattery arrives with it.

Investing $1 million at different stages of life

Three example life stage scenarios are provided below. Each describes one possible allocation which might suit the situation.

Retired, or within five years of retiring

Someone who expects to start regular withdrawals within about five years faces sequence risk. A bad market in the first years of withdrawals does damage a later fall of the same percentage cannot match. The portfolio is at its largest then, and withdrawals to fund your lifestyle force sales of underlying investments in a down or falling market. The tempting approach to mitigate this risk is to retreat from growth assets (shares and property) altogether, though that just trades one risk for another. Making your retirement income last can mean thirty years of withdrawals, so your portfolio needs to be built to last. A better approach is a deeper reserve, which it might help to consider as being measured in years of withdrawals rather than in dollars.

An allocation here might hold $450,000 in global shares, $130,000 in New Zealand and Australian shares, $270,000 in fixed interest, and $150,000 in cash and term deposits. For a reader already drawing $50,000 a year from the portfolio to fund their retirement lifestyle, after NZ Super and any other income, the cash covers three years of withdrawals. The fixed interest, chosen for quality and intended to move far less than shares, can fund several more. A bear market is usually defined as a fall of 20 percent or more from a recent high. If one arrives early in retirement, this reader funds spending from the cash and fixed interest and leaves the shares to recover, instead of selling them at depressed prices. When markets recover, gains from shares are rebalanced back into cash and fixed interest to rebuild the reserve. A reader whose spending can flex, because travel can wait a year or part-time income continues, needs a shallower reserve; one drawing $80,000 a year needs a deeper one. What income a million dollars supports in retirement depends on factors including spending rate, other income sources, investment approach and performance, and longevity, rather than on allocation alone.

In your fifties with about ten years before drawing on it

A mortgage-free couple in their mid-fifties sold their business, kept working in salaried roles, and expected to for another ten years. Their salaries covered their living costs with a surplus to invest each year, and they did not expect to draw on the sale proceeds, a little over $1 million, until their mid-sixties. With term deposit rates rising, they wanted to ladder the whole amount across bank term deposits, which felt prudent. Term deposits suit money needed in the next few years. Their retirement could last thirty, so most of the million would have sat in an investment chosen for a horizon it did not have. Beyond a planned home renovation and a year of travel, none of the money was needed for at least a decade. The opposite instinct, investing every dollar the day the sale settled, carried its own risk: a fall in the first months they were not prepared to sit through.

An allocation for a reader in their position might hold $500,000 in global shares, $180,000 in New Zealand and Australian shares, and $200,000 in fixed interest. The remaining $120,000 sits in term deposits matched to the renovation and the travel. The middle of their retirement is probably more than twenty years away, which is why most of the money is in shares. They are not yet drawing on the portfolio, so a fall in markets forces no sales, and their surplus income buys more at lower prices while it lasts. The allocation also assumes they could watch the balance fall by a third in a bad year without abandoning it, which they confirmed before a dollar was invested.

At 40 with two decades before the money is needed

Someone with twenty years of salary ahead and no plans to draw on the money has the longest horizon of the three, so the allocation carries the most growth assets.

An allocation for this reader might hold $650,000 in global shares, $150,000 in New Zealand and Australian shares, and $200,000 in fixed interest, with no cash at all. The New Zealand and qualifying Australian-listed shares carry less currency risk and sit outside the FIF rules. The fixed interest is there to reduce the swings and to provide something to sell when rebalancing, which is why idle cash has no place here. In a simplified illustration, if shares fell 30 percent while the fixed interest held its value, the portfolio would be worth about $760,000. Nothing about the allocation would need to change, because falls of that size are expected somewhere in a twenty-year run. Structure matters more for this reader than for the other two, since a small annual tax difference has the longest time to compound.

When to invest $1 million: all at once or in stages

Expected returns and historical evidence favour investing immediately. Vanguard's research across global markets from 1976 to 2022 found a lump sum beat a staged entry about two-thirds of the time over rolling one-year periods. In its 60/40 example, investing immediately produced about 1.8 percent more median wealth after one year than staging the entry over three months. Other, similar research reaches the same or very similar conclusions. Staging equal amounts of a large sum over a set period, an approach known as dollar-cost averaging, trades a little expected return for far less regret if markets fall the week after you begin. A staged entry over six to twelve months is a reasonable compromise for anyone who would find an early fall on the whole sum hard to sit through.

Where seven-figure money goes wrong

Family requests, tempting yields, and frightening headlines all compete with the allocation you wrote down. The largest threat to a windfall is usually your own actions. Loans or gifts to family, a relative's business opportunity, or hasty investment decisions are the commonest ways a lump sum shrinks. Decide your policy before anyone asks, and if you are brave enough to loan to family, document it legally as a bank would. Chasing headline dividend and interest income is another potential pitfall worth naming, since a high yield can signal a falling or risky asset. Redesigning the portfolio whenever the headlines turn grim is the other common one to watch for. The remedy for each is the allocation you wrote down while calm, re-read before any change made under pressure.

How $1 million is taxed in New Zealand: PIE, FIF and structure

Structure decides who owns the portfolio and how its returns are taxed. It is usually far cheaper to get structure right at the start than to unwind later. A portfolio investment entity is a common investment structure in New Zealand, and the structure of most KiwiSaver Schemes; it taxes your share of fund income at your prescribed investor rate, capped at 28 percent. If you hold offshore shares directly, the foreign investment fund rules apply once the total original cost of your non-exempt offshore holdings exceeds the threshold. The rules attribute taxable income to you personally under one of several methods, and can tax you in a year the shares paid you nothing. A PIE holding overseas shares does the same at fund level, so both routes can tax a losing year; the differences are the rate and who does the paperwork. Which arrangement leaves more after tax depends on your exact holdings, prescribed investor rate, your marginal rate, foreign tax credits, and the calculation method open to you. Any potential tax gap between structures is often smaller than financial product provider marketing implies, so treat tax efficiency as a tiebreaker between otherwise similar options, never the whole reason to pick a product.

One exposure is specific to portfolios of this size. US shares and US-listed funds held directly in your own name can require a US estate tax return on death once they exceed USD 60,000. The estate may then face a liability at rates rising to 40 percent. The rule applies to a New Zealand investor who is neither a US citizen nor US-domiciled, and the position differs for those who are. A global share allocation of several hundred thousand dollars held directly is well inside that range. Holding the same exposure through a New Zealand-domiciled fund generally avoids it, because you own units in the fund rather than the US shares themselves.

A family trust may serve defined succession or asset-protection objectives, but only where it is properly established, administered in practice, and run by trustees who observe their duties. Take personalised legal and tax advice before settling assets on one, and treat any purely tax-driven argument for a trust with suspicion until someone shows you the numbers.

Typically, someone with a sizeable sum to invest would not consider KiwiSaver, as money in a KiwiSaver Scheme is generally locked until age 65 apart from limited exceptions, and there are other ways to invest in a very similar manner. Any existing KiwiSaver balance is still part of your overall investments, so count it when working out how much you hold in shares and fixed interest across everything you own.

Choosing the specific investments last

By the time products are being considered, the allocation has already decided what each holding must do, and a few differences settle the rest. What matters: whether the holding is broadly diversified, the total cost including any underlying funds, how quickly you can withdraw and on what conditions, and whether you can explain what you own. What is usually a distraction: the brand on the fund, last year's performance ranking, and a large number of holdings quoted as if it measured diversification. If a provider cannot answer these questions plainly, look elsewhere.

Funds are usually the default at this scale, because broad diversification and professional administration matter more than owning shares by name. Direct holdings suit investors who want control over specific exposures and will carry the administration in full, including FIF returns where they apply. One well-chosen platform holding many funds is already diversified; two providers do not by themselves necessarily reduce investment risk.

What fees cost on $1 million, and what they buy

When considering fees which are often explained in percentages, translate figures into dollars. For instance, a combined 1 percent in management and advice fees on a $1 million portfolio is $10,000 a year. Advised portfolios in New Zealand typically run between 1.2 and 2.1 percent all-in once platform, custody, and fund costs are counted, so the first question for any provider is the all-in figure in dollars. Our own fees are published in full, with worked examples.

What a good fee buys is a portfolio built and maintained on evidence rather than opinion: the allocation set and reviewed, rebalancing done when it is due, structure chosen with care, and withdrawals planned. Under a discretionary investment management service, the buying and selling is handled for you, so a bad quarter never turns into a badly timed sale. Vanguard's research on the value of advice puts it at up to 3 percent in net returns, delivered unevenly rather than every year and with behavioural coaching the largest single part. On a million dollars, that is the difference between the fee being a cost and the fee being the cheapest part of the arrangement.

Liquidity: how quickly you can get the money back

Liquidity is one of the quiet advantages of a share and bond portfolio over property. Most listed shares and funds can be sold within days at close to the quoted price, and the money settles within a few business days. Direct property takes months, plus transaction costs in the tens of thousands. Two exceptions are worth knowing. Thinly traded shares can sell well below the quoted price when you need the money. Some unlisted funds can suspend withdrawals in stressed markets, a condition set out in the offer document and rarely read until it applies. Before counting any holding as something you could sell quickly, check how easily it trades and on what terms.

The test of a finished allocation

The allocation is not finished until you can say which part of the million is kept out of share markets, and how far the rest could fall in a bad year without you changing course. It also needs one more answer: what change in your own circumstances, rather than in markets, would justify changing it. Once those are answered, the remaining work is leaving the portfolio alone while compounding does the slow, unglamorous part.

A complimentary initial conversation with one of our advisers can help you decide how much of the million should be kept out of share markets and how much can go to growth. It can also aid decisions such as whether to invest at once or in stages, and perhaps most importantly, start to model what your million might reasonably be expected to achieve, or not achieve!
