Inherited a Large Sum? What to Do Next

If you have recently inherited a significant sum in New Zealand, the decisions you make in the next twelve months can shape your financial freedom for decades. This guide explains what to do after inheriting money in New Zealand, covering tax, relationship property, investment options, potential wholesale traps, and common mistakes. Whether the inheritance arrived as cash, shares, property, or a combination, the considerations below are relevant.

But before any of the practical guidance below, the most useful thing we can say is: there is no rush. The money will wait.

An inheritance almost always arrives alongside loss. Sometimes the grief is raw and recent. Sometimes it is complicated by family dynamics, by a sense of guilt, by relief you did not expect to feel, or by the strange conflict of receiving financial good fortune at the worst possible time. All of these responses are normal.

If you are reading this shortly after losing someone, start with the next section and give yourself time.

If at any point you would like to talk through your situation, our initial consultation is complimentary and entirely without obligation.

Grief, Guilt, and the Pressure to Act

Grief clouds judgement in ways most people do not recognise at the time. Decisions might feel urgent when they are not. Generosity could feel right when it may be premature. The fear of making a mistake can push you towards the first option someone suggests simply to make the discomfort stop.

For some people, the inheritance carries a weight beyond money. You may feel undeserving, or conflicted about benefiting from someone’s death, or anxious about honouring their memory through how you handle the funds. These feelings are entirely common and do not need to be resolved before you can make good decisions. They just need to be acknowledged.

Park the money in an on-call savings account. Take three to six months before making any permanent financial commitments. The interest rate will be unremarkable, and the protection it gives you against a rushed decision is worth far more than the foregone return.

To be clear: the pause applies to major financial decisions, not to estate administration. Applying for probate, notifying banks and insurers, filing the deceased’s final tax return, securing property, and keeping the estate moving are all immediate tasks, and some are time-sensitive. Many New Zealand estates take six to eighteen months to settle, and planning often happens in parallel with the administration process. The pause is about resisting the pressure to invest, gift, or deploy the capital before you have thought it through.

Everyone Will Have an Opinion

When word gets out about an inheritance, people surface. Relatives may have expectations, particularly if they feel the distribution was uneven. Your bank will call once a six-figure or larger deposit lands. The bank may suggest products they happen to offer. An acquaintance who has done well in property will encourage you to buy a rental. Someone will mention cryptocurrency. Your nephew might suggest a TikTok course on forex trading. (Politely decline.)

The simplest defence is a decision, made early, to take no major action for a defined period. If anyone asks, you are working with a professional and the plan is still being finalised. This is both true and sufficient.

The First Few Months: A Practical Sequence

Here is what a well-managed post-inheritance period typically looks like.

In the first few weeks, the priority is housekeeping and decompression. Park the net proceeds in one or more on-call savings accounts. If the sum is large, consider spreading it across institutions to stay within the Depositor Compensation Scheme limit of $100,000 per depositor, per licensed deposit-taker. (This guarantees you will not lose most of the sum in the highly unlikely event of a bank failure). Confirm all estate-related tax obligations with the executor’s accountant: the deceased’s final income tax return, any trust distributions, and anything else requiring attention. If you are the executor, you already know how much administrative work is involved. If you are purely a beneficiary, use this time to gather the documents you will need later: the grant of probate, bank statements, share registries, and property titles.

Over the following month or two, the focus shifts to planning. This is the time for important conversations: with your spouse about goals and priorities, with a family lawyer about relationship property and estate structures, and, if you choose to engage one, with a financial adviser about your options. One thing worth checking early: whether the professionals who served the deceased’s estate are the right ones for what comes next. The estate’s lawyer may be a wills and trusts specialist with limited experience in relationship property. The accountant may be a small-business practitioner unfamiliar with investment tax or the Foreign Investment Fund rules. This is a natural transition point.

From month three or four onwards, you are ready to deploy. The plan exists, the goals are sequenced, the tax position is clear, and you have had enough time to separate emotional impulses from considered decisions. Some people move faster, some slower. The point is to sequence the thinking before the spending. If you decide to work with a professional, a financial planner helps you determine what to do with the money to achieve what you want in life.

Do You Pay Tax on an Inheritance in New Zealand?

The short answer is no. New Zealand has no inheritance tax, no estate duty, and no gift duty. The capital itself is not taxable.

New Zealand’s rules on inherited wealth differ meaningfully from those in Australia, the UK, and the US. The relevant bodies include Inland Revenue (tax), the Financial Markets Authority (investment regulation), and the frameworks set by the Property (Relationships) Act 1976 and the Reserve Bank’s Depositor Compensation Scheme. This guide covers each where relevant.

What is taxable is the income earned on inherited assets from the moment they become yours. Interest on deposits, dividends from shares, and rental income from property are all subject to income tax at your marginal rate. For most people inheriting a meaningful sum, the combined income from the inheritance and any existing earnings will push them into the 33% or 39% bracket under current New Zealand tax settings.

Inherited property. If you inherit residential property in New Zealand, the bright-line test does not apply when you sell it. This is a statutory exemption covering sales by the executor, the administrator, or the beneficiary. You do not need to hold the property for any minimum period. Other tax rules may still apply in some circumstances, particularly if the property was part of a business or development, so professional advice is worth seeking before selling.

Overseas inheritances. If the inheritance originates overseas, the picture is more complex. A UK estate may involve UK inheritance tax, payable before distribution. Ongoing income from overseas assets you retain is taxable in New Zealand. If you inherit overseas shares or units in foreign funds with a cost basis exceeding NZ$50,000, the Foreign Investment Fund rules apply. If you inherit a foreign superannuation interest, a separate set of rules governs withdrawals and transfers. An accountant experienced in cross-border estate issues is a worthwhile early conversation.

US shares held by a New Zealand resident. This one catches many families by surprise. If the deceased was a New Zealand resident who held US-listed shares or ETFs directly in their personal name, the estate may face US estate tax on those assets. The US threshold for non-US residents is just USD$60,000, and the rate is up to 40% on the value above the threshold. This obligation falls on the estate, not on the beneficiary directly, though it can reduce the total inheritance and delay distributions while the US filing is resolved. Holding equivalent investments through a New Zealand-domiciled managed fund avoids this exposure entirely, which is worth knowing for your own long-term planning as well.

What Most People Get Financially Wrong After Inheriting

There are a few common responses to a large inheritance in New Zealand, and each carries risks worth examining.

Leaving it all in the bank. This is the most popular default. It feels safe. The number on the statement stays still. But, consider what happens over time.

Suppose you inherit $800,000 and leave it in the bank at 4% gross interest. The deposit earns $32,000 a year. At a 33% marginal tax rate, roughly $21,400 remains after tax: an after-tax return of about 2.7%.

If inflation averages close to the Reserve Bank’s 2.5% midpoint, prices roughly double over 30 years. In 30 years your bank balance still reads $800,000. In today’s dollars, it buys approximately what $380,000 buys now. The number stayed the same. The purchasing power more than halved.

New Zealand has roughly 25 licensed deposit-takers, but the Depositor Compensation Scheme covers only $100,000 per depositor per institution. An $800,000 balance at one bank leaves $700,000 above the threshold. The real risk is unlikely to be a bank failure. It is the slow, invisible erosion described above. Term deposits are hardly the safe option most people assume.

Gifting large sums to children immediately. The impulse is understandable, especially if you feel the money was always meant to flow down a generation. But premature gifting has consequences. Once the money is gone, it is gone. If your own circumstances change, you cannot recall it. If your child is in a relationship, the gift may become relationship property under New Zealand law. And the arithmetic of your own retirement may not support the generosity you feel in the moment. Only gift once the full picture is clear.

Why Inheritance Proceeds Should Usually Stay Out of KiwiSaver

It may seem logical to put a large sum into KiwiSaver, which is, after all, a simple managed investment most people understand. But KiwiSaver is designed for retirement savings with strict withdrawal conditions. You generally cannot access KiwiSaver funds until age 65, with limited exceptions for first-home purchases or significant financial hardship.

If you are already over 65, KiwiSaver has a different limitation: it can only be held in one person’s name. You cannot jointly invest a shared pool of proceeds with your spouse, which limits its usefulness for couples making decisions together about a large capital sum, especially should one of you pass away.

KiwiSaver remains a useful tool for regular contributions from employment income, but as a vehicle for deploying a significant inheritance, it is usually the wrong fit. Accessible managed funds, held outside KiwiSaver, offer similar investment exposure with the flexibility to withdraw when you need to.

One more thing before investing: if you carry any high-interest debt, paying it off first is almost always the right move. A car loan with an interest rate of 10% or more is costing you more than any realistic investment return will earn. Clear the expensive debt, then invest what remains.

Your Age Changes the Menu

An often-overlooked reality: the younger the inheritor, the wider the range of sensible options.

A 40-year-old inheriting $500,000 faces genuinely different choices from a 60-year-old inheriting the same sum. The 40-year-old may be weighing whether to repay a mortgage early, start or buy a business, purchase an investment property, or build a diversified share portfolio. A financial adviser (such as the team here at Become Wealth) can help weigh most of these competing options, because the trade-offs depend on the individual’s existing debt, assets, income, goals, and risk tolerance.

As we age, many of these choices self-select out. A 60-year-old has hopefully already repaid the mortgage, is unlikely to want to start a business, and may be unwilling to take on the obligations of becoming a landlord. By the time you are in your sixties, the conversation narrows naturally towards investment management and retirement income planning.

For younger inheritors, there is a separate risk worth naming. The allure of high-risk, high-excitement approaches tends to be stronger when you are younger and the sum feels like “found money” rather than the product of decades of your own hard work and restraint. Cryptocurrency, forex trading courses, or international schemes promoted by financial influencers on social media can all seem more appealing when the capital arrived suddenly and potentially without effort. The money may not have cost you anything to earn, grief aside, but it will cost you everything if you lose it. If the inherited sum is the largest amount of money you have ever held, approach it with the seriousness it deserves.

Inheritance and Risk Reduction

Receiving an inheritance can be a good moment to rethink whether your existing insurance still makes sense. Many people take out life insurance because they do not yet have enough savings or assets to fully support their family if something were to happen to them; an inheritance may reduce or even remove the need for that cover. At the same time, having more financial flexibility can make it possible to consider options that were previously unaffordable, such as more comprehensive health insurance. Reviewing insurance after an inheritance helps ensure your cover reflects your current situation, rather than financial limitations from earlier in life.

Be Wary of Wholesale Investment Offers

Here is a scenario worth preparing for: shortly after word gets out about your inheritance, someone approaches you with a private investment opportunity. It may be a property development, a mortgage fund, or an unlisted venture promising double-digit returns. They call it a wholesale offer, and because you now have capital, you may technically qualify.

Wholesale investments operate under a different regulatory framework from the retail products most New Zealanders are familiar with. Under the Financial Markets Conduct Act, offers made to wholesale investors are exempt from the disclosure requirements imposed on retail offers. The offeror does not have to provide the same level of information. The investment does not need a licensed manager or independent supervisor. And the Financial Markets Authority (FMA) has limited ability to intervene if things go wrong.

The qualification thresholds are lower than many people expect:

• You are investing $750,000 or more in a single product, or
• Your net assets exceed $5 million, or
• You self-certify as an “eligible investor” on the basis of prior experience.

For someone who has just inherited a meaningful sum, at least one of these thresholds may be met.

The FMA has flagged concerns clearly. In a thematic review of the wholesale investor exclusion, the regulator found promotional materials advertising high fixed returns while downplaying risk, digital advertising deliberately targeting inexperienced investors, and eligible investor certificates confirmed on grounds as flimsy as owning a KiwiSaver account or a rental property.

The Du Val Group, once a prominent Auckland property developer, collapsed in 2024 owing more than $268 million to investors, contractors, and lenders. Investors in the group’s Build to Rent Fund are expected to recover roughly 41 cents in the dollar. Investors in the Mortgage Fund and Opportunity Fund may recover less, or nothing. The group is now in statutory management, and the FMA investigation remains ongoing.

Three practical filters before committing capital to any wholesale offer:

1. Is the investment regulated by a licensed manager, or are you relying on the offeror’s good faith alone?
2. Can you get your money out within a reasonable timeframe, and on terms clearly stated in writing?
3. Who confirmed your eligible investor certificate, on what grounds, and did they actually review your experience?

If any of these questions produce evasive answers, the investment is telling you something. Listen to it.

Cash, Shares, Property, or Business Interests: Different Inheritances, Different Decisions

Not all inheritances arrive as a bank transfer. What you inherit can shape the decisions you face.

Cash is the simplest starting point. The key decisions are how, when, and where to deploy it.

An existing share portfolio requires a different conversation. The deceased’s portfolio was built for their goals, their risk tolerance, overall asset base, and their time horizon. Yours are almost certainly different. Inheriting an investment portfolio does not oblige you to keep it as it stands. Reviewing and restructuring it to match your own circumstances is a must.

Property brings holding costs: council rates, insurance, maintenance, and potentially tenants. If the inherited property does not fit your financial plans, selling is a legitimate option. As noted above, inherited property is exempt from the bright-line test. Your ancestor who worked hard enough to own a house would usually prefer you made the smartest financial decision, not the most sentimental one.

Business interests add a layer of complexity most inheritors do not anticipate. If you inherit shares in a private company, check the shareholders’ agreement immediately. Check it with a lawyer experienced in this area of law. Many agreements include pre-emptive rights, forced-sale provisions, or restrictions on who can hold shares. You may also inherit governance obligations, including directorship responsibilities if the deceased sat on the board. If the company is actively trading, get legal advice quickly; these matters cannot wait for the grief pause.

Some inheritances involve all of the above, plus vehicles, personal effects, and debts. If you are waiting for the estate to settle, use the time to plan rather than simply waiting.

Relationship Property: A Consideration Worth Raising Early

Under the Property (Relationships) Act 1976, inherited assets are classified as separate property. This means they belong to the person who received them, not to both spouses, even in a long-term relationship.

However, separate property can become relationship property through commingling. Depositing inherited money into a joint bank account, using it to pay down a joint mortgage, or purchasing a jointly held asset can all change the classification. Even hanging an inherited picture in the lounge you share with a spouse can mean it is now classed as joint property! Once the boundary has been crossed, unwinding the position is difficult, if possible at all.

Some inheritors use a family trust to ring-fence inherited assets and preserve their separate property status. This can be effective, though trusts are not the automatic answer they were a generation ago. They carry their own costs, compliance obligations, and limitations. From 1 April 2024, the trustee tax rate on retained income increased from 33% to 39%, aligning with the top personal marginal rate. There are still processes to be followed, and a trust may not protect an inheritance in all instances (for instance, if you inherit a property, gift it to a trust, then move into it with your spouse, you would likely still be exposed). For smaller inheritances, the overhead may outweigh the benefit. A contracting-out agreement (sometimes called a prenuptial or postnuptial agreement) is another mechanism worth discussing with a family lawyer. The right structure depends on the size of the inheritance, your family situation, and your long-term intentions.

Transparency with your spouse matters here. Seek legal input before making decisions about how the inherited funds are held, so you are both informed and protected.

Getting on the Same Page With Your Spouse

If you have a spouse, an inheritance belonging to one person still affects both. How the money is managed, whether it changes your lifestyle, and what it means for your shared future are conversations worth having openly.

These conversations can surface unexpected differences. One spouse may feel the inheritance should be preserved for the next generation. The other may want to pay off the mortgage, travel, or fund a more lavish retirement. All of these instincts can be valid. The point is to surface them early and work through the priorities together. Structured financial planning turns competing wishes into a sequenced set of goals, each backed by numbers, so one does not crowd out the others.

Consider a common situation: a woman in her late thirties inherits her mother’s estate, comprising $350,000 in cash, a rental property, and a modest share portfolio. Her (recent) husband suggests using the cash to pay off their joint mortgage. This is well-intentioned, but it would convert separate property into relationship property. A brief conversation with a family lawyer before making the transfer allows her to consider the separate property classification, weighing whether the inheritance could benefit their joint life together. Making an informed decision is key, whatever this woman chooses to do.

“Many people who inherit a significant sum have never had to make a financial decision of this scale,” says Jonny McNamee, a financial adviser at Become Wealth. “The ones who do it well almost always have one thing in common: they involve their spouse in the conversation before they commit to anything. The inheritance may belong to one person legally, but the decisions affect both lives. Getting aligned early makes everything else easier.”

Update Your Will and Estate Plan

An inheritance changes your asset base, and your existing will and estate documents may no longer reflect reality. If the inherited sum is held differently from your other assets, whether in a trust, a separate bank account, or a mix of property and shares, your will needs to account for how those assets are owned and who should receive them. A will written when your primary assets were a house and a KiwiSaver account looks very different from one written after a substantial inheritance.

This is also a practical moment to check whether your enduring powers of attorney are current and whether the people named in them are still the right choices. If you have placed inherited assets into a family trust, the trust deed and your will need to work together rather than in isolation; misalignment between the two is one of the more common causes of post-death disputes. A brief review with a lawyer experienced in estate planning is worthwhile, and the cost is modest relative to the sums involved.

Building a Portfolio Designed to Last

Once the grief pause is over, the tax position is understood, and you and your spouse are aligned, (hopefully) the question becomes: what do you actually do with the money?

An initial response might be to repay any debt. This makes a lot of sense in most cases.

Then, for many inheritors, the answer can be to build a diversified investment portfolio spread across asset classes and geographies. Diversification is key, as New Zealand accounts for roughly 0.06% of global equity markets and carries elevated natural disaster risk relative to most comparable countries. Concentrating an inheritance in a single market or geography leaves you exposed to events a diversified portfolio would absorb.

A blend of defensive and growth financial assets may deliver total returns in the range of 5% to 6% over the long term. This is designed to steadily grow purchasing power over decades, which is exactly what most inheritors need. If you add this to what you’ve already built, you might be in a robust financial position.

For those approaching or already in retirement, the question becomes more specific: how do you create a reliable income without running down your assets too quickly? The shift from accumulation to retirement income planning is one of the most important transitions in personal finance, and an inheritance can meaningfully accelerate it.

Do You Actually Need a Financial Adviser?

If the inheritance is modest, your goals are straightforward, you have a solid grasp of investment fundamentals, and you are comfortable riding out market volatility without making reactive decisions, a self-directed approach can work well.

Where complexity tends to break DIY approaches is in the areas most inheritors eventually face: ensuring the funds are supporting and enabling your life, not the other way around. This includes financial modelling, appropriate diversification, tax-efficient structuring across multiple investments, relationship property preservation, behavioural discipline during market crashes, due diligence on wholesale offers, and potentially coordinating the moving parts between accountant, lawyer, and your financial system. Whatever your personal preference, independent research consistently shows the value of good financial advice exceeds the fee by a significant margin.

Good advice has a cost. Going without it typically costs more.

The Questions Worth Asking First

Your finances exist to serve your life, not the other way around. Before a single dollar is invested, the real work is understanding what you are investing for. The questions below are where good financial advice starts:

What has been weighing on you financially? An inheritance can resolve long-standing worries, but only if you identify them first.

What do you want your life to look like in five years? Think about where you live, how you spend your time, and who you spend it with.

Are there people you want to help? If so, how much can you give while still meeting your own needs?

What concerns, feelings, or needs do you have when you think about money?

Depending on how much you now have, the answers to these questions shape everything: how your financial life should be constructed, how much risk is appropriate, how income is drawn, when to be generous and when to be cautious, and what success actually looks like for you.

All at Once, or Gradually?

Once you have a plan, the question often becomes: invest the full sum immediately, or phase it in over time? The data consistently favours investing earlier rather than later. Markets tend to go up more often than they go down, and money waiting on the sideline earns less than money at work.

In practice, the decision is also psychological. If investing a large sum in one go keeps you awake at night, a phased approach over three to six months is a reasonable compromise. The small statistical cost of phasing is easily offset by the psychological benefit of sleeping soundly after a market dip the week you invested everything.

From Inheritor to Steward

An inheritance is the accumulated effort, restraint, and foresight of someone who is no longer here. The person who left it to you probably trusted you to do something worthwhile with it.

The shift from inheritor to steward begins with a pause, moves through planning, and arrives at an overall financial life you are genuinely comfortable with. If the inheritance has arrived but the plan has not, our team works with individuals and families across New Zealand. Your initial conversation with us is complimentary and entirely at your pace.
