What Is Generational Wealth and How to Build It?

How to build, protect, and pass on wealth across generations in New Zealand

Generational wealth is any financial asset passed from one generation of a family to the next. Shares, property, businesses, funds, KiwiSaver balances, cash savings, and even intellectual property all count. In practice, generational wealth in New Zealand usually comes from a combination of property, diversified investments, and the financial habits parents model for their children.

Whether you are still building wealth in your 30s or 40s, or you are in your 50s, 60s, or beyond and thinking about how to pass it on, this article covers the three things every family needs to get right: building assets worth passing on, protecting them from avoidable erosion, and transferring them in a way your family can actually sustain.

Why Generational Wealth Matters in New Zealand

New Zealand is about to experience the largest intergenerational wealth transfer in its history. According to JBWere, annual inheritances of roughly $27 billion in 2024 are projected to grow toward $1.6 trillion cumulatively by 2050. Baby boomers make up about 23 percent of the population yet hold more than half the country’s household wealth, much of it locked up in residential property.

Globally, a 20-year study of more than 3,200 families by the Williams Group found 70 percent of wealthy families lose their wealth by the second generation and 90 percent by the third. The Chinese proverb says it plainly: “wealth does not pass three generations.” New Zealand families, though, have genuine structural advantages here. No inheritance tax, no gift duty, well-established trust law, and a relatively simple tax code. These factors remove several of the structural hurdles families in the US, UK, and Europe face.

Consider two people entering their 20s. One carries a $50,000 student loan. The other graduates debt-free because a parent or grandparent covered the fees. Same degree, same job market, wildly different starting positions. The debt-free graduate can funnel cash into investments, take time out to travel, or save a house deposit while the other spends years playing catch-up. Multiply this across an entire family tree and the compounding effect becomes profound. Generational wealth provides choices. The choice to take a lower-paying role you love. The choice to start or buy a business without betting the house. The choice to ride out economic downturns from a position of strength rather than panic.

How to Build Generational Wealth: A Three-Stage Framework

Generational wealth is not reserved for the ultra-rich. In New Zealand, the median household net worth now sits at about $529,000, according to Stats NZ, driven largely by property values. Many families sitting on this level of wealth do not feel rich, yet the figure represents a meaningful head start for the next generation if managed well. Building wealth you can pass on follows the same principles as building wealth for yourself, with one critical difference: the time horizon stretches across decades, which actually works in your favour.

Stage 1: Lay the Foundation

Before thinking about building for the next generation, secure your own position. This means clearing consumer debt (credit cards, car loans, buy-now-pay-later schemes) and getting your basic estate documents in order. A current will and an enduring power of attorney covering both property and personal care are non-negotiable. Only about 55 percent of New Zealand adults have a will, which means nearly half the population will have their estate distributed according to legislation rather than personal wishes.

Skipping this step makes everything else fragile.

Stage 2: Accumulate and Diversify

Compounding is the single most powerful force in wealth creation. A 25-year-old investing $500 per month at a 7 percent annual return will accumulate roughly $1.2 million by 65. Wait until 35 and the same contribution produces about $567,000. Those 10 years of delay cost more than half the outcome. In our experience working with New Zealand clients, this is the point where people underestimate what disciplined, boring investing can achieve over a multi-decade horizon, and overestimate what property alone can deliver.

For most New Zealanders, a diversified investment portfolio combining local and international equities, bonds, and some property exposure offers the most reliable path.

On property and leverage. New Zealanders’ attachment to residential property is well-documented, and partly rational: bank lending allows investors to leverage capital in a way listed equities generally do not. A 20 percent deposit on a $1 million property means a $200,000 outlay controlling $1 million of asset value. If the property rises 5 percent, the return on your equity is 25 percent. Leverage magnifies returns in both directions, however, and this is the part many property advocates gloss over. The same maths work just as powerfully in reverse during a downturn. Property can absolutely be part of a generational wealth plan, but relying solely on it is a gamble, particularly when much of baby boomer wealth is already property-heavy. Diversification remains the simplest form of risk management available.

A business can also build intergenerational equity, but only about 30 percent of family businesses survive into the second generation and around 12 percent into the third, according to the Family Business Institute. If the children are not interested or capable, selling the business and investing the proceeds may serve the family far better than forcing an unwilling heir into the corner office.

Stage 3: Protect and Structure

Family trusts have long been a cornerstone of New Zealand estate planning. Under the Trusts Act 2019, trusts can now run for up to 125 years (up from the former 80-year maximum), and the legislation places clear obligations on trustees around record-keeping, beneficiary disclosure, and good-faith decision-making. A trust separates legal ownership from beneficial ownership, which can protect assets from creditors, relationship property claims, and poorly timed decisions by young beneficiaries.

A common misconception: trust income retained by the trustee is now taxed at 39 percent (from 1 April 2024), leading some families to question whether trusts still make sense. The answer depends entirely on your situation. If the trust distributes income to beneficiaries on lower marginal rates, the effective tax outcome improves. If the trust accumulates income, the rate is higher than most individuals would pay. Getting the distribution approach right is a conversation for your accountant and lawyer, not a dinner table guess.

Another area families commonly misunderstand is the bright-line test. When residential property is inherited, the bright-line clock generally resets from the date the estate or trust acquires it for distribution purposes. Families who assume inherited property is automatically exempt can face unexpected tax bills if they sell within the applicable period.

Why Most Generational Wealth Does Not Last

According to the Williams Group research, the top three causes of wealth transfer failure are not bad investments or poor tax planning. Those account for less than 5 percent of failures. The real causes are behavioural, emotional, and entirely within the family’s control:

• Breakdown of trust and communication (roughly 60 percent of failures). Money is the last thing many families discuss openly, and it becomes the first thing they fight about when someone dies. A closer look at the thorny issues in New Zealand’s intergenerational wealth transfer reveals further complications around timing, aged care costs, and the Bank of Mum and Dad.
• Inadequately prepared heirs (about 25 percent). Receiving a large sum without financial literacy, experience, or guidance is like handing someone car keys without a driving lesson.
• No shared mission or purpose for the wealth (about 10 percent). When families lack a common understanding of what the money is for, spending and investment decisions fragment quickly.

Notice what is not on the list above. Market crashes. Inflation. Interest rates. All the things people lose sleep over barely register. This is encouraging, because controllables are fixable.

The Real Inheritance: Financial Literacy, Communication, and Values

Harvard’s Study of Adult Development, running for more than 80 years, concludes the strongest predictors of wellbeing and health in later life are close relationships, not net worth. Money creates options, but it does not create fulfilment on its own. The families who preserve wealth across generations tend to share concrete habits, not just good intentions:

• They hold structured money conversations. Research suggests children form basic financial habits by the age of seven. Waiting until they are adults is leaving it too late. An annual family finance meeting, even an informal one, where parents share household goals, explain how investments work, and ask children what financial questions they have, normalises money as a topic rather than a taboo.
• They model behaviour rather than lecture. Children watch how parents spend, save, invest, and react to financial setbacks. The lesson absorbed through observation is far more durable than any slide deck.
• They introduce heirs to the family’s advisers early. Bringing adult children to a meeting with your financial planner before any inheritance event builds familiarity and competence. It also gives the adviser a chance to understand the next generation’s goals and risk appetite.
• They focus on values first and dollars second. Work ethic, self-reliance, contribution to community, and an understanding of risk are assets no market crash can wipe out.

Fidelity research shows roughly 88 percent of millionaires are self-made. They built wealth through consistent habits, not windfalls. Passing on those habits alongside some capital gives the next generation the best of both worlds: a financial head start and the mindset to make the most of it.

Building Generational Wealth: New Zealand Versus the Rest of the World

Much of the global advice on generational wealth is written for an American audience with American tax rules. The differences matter.

In the US, families routinely spend significant sums on estate tax planning, Roth IRA conversions, generation-skipping trusts, and complex charitable structures to minimise a 40 percent federal estate tax. In the UK, inheritance tax is 40 percent above £325,000. A New Zealand family passing on a $2 million estate faces none of these imposts. This structural benefit should not be taken for granted; tax policy is always subject to change and successive governments have floated broader capital or wealth taxes.

New Zealand does not offer some of the tax-advantaged transfer vehicles available elsewhere. There is no equivalent of a US 529 education savings plan with tax-free growth, and KiwiSaver offers limited beneficial tax treatment. The relative simplicity of the New Zealand tax code means less opportunity for sophisticated avoidance, but also far less opportunity to be caught out by unexpected liabilities.

One genuine risk for New Zealand families is asset concentration. Property comprises roughly 48 percent of total household assets nationally, and many families hold even higher proportions. A sustained property downturn could materially erode generational wealth. Families building a legacy should think carefully about whether their assets are spread widely enough to withstand one bad decade in a single sector.

Common Questions About Generational Wealth

Is this only for the wealthy?

No. Generational wealth can be a paid-off family home, a modest share portfolio, or the gift of a debt-free education. Contributing to KiwiSaver, paying down your mortgage ahead of schedule, investing small sums regularly, and having a will in place are all meaningful steps, regardless of income or assets.

Does New Zealand have an inheritance tax?

Not currently. Estate duty was abolished in 1992 and gift duty in 2011. This makes New Zealand one of the most favourable jurisdictions in the developed world for intergenerational transfers, though future governments may change this.

Is a family trust still worth it after the 39 percent trustee tax rate?

It depends entirely on your circumstances. Trusts still offer asset protection, controlled distribution to beneficiaries, and the ability to bypass probate. The tax picture varies by family. Professional legal and accounting advice is essential before setting up or restructuring a trust.

What is the single biggest mistake families make?

Not talking about money. The Williams Group study found roughly 60 percent of wealth transfer failures stem from breakdowns in family communication. Having honest, structured conversations about money, expectations, and values is the single most effective step a family can take. Even one annual sit-down, where all generations are present, can change the trajectory.

Generational Wealth and How to Build It

Generational wealth is not about creating a dynasty or raising children who never have to work. Most self-made millionaires will tell you the habits and lessons learned along the way were worth more than any inheritance. The goal is to give the next generation a running start, not a hammock.

New Zealand families have genuine advantages: no inheritance tax, well-established trust law, and a simple tax code. Pair these with consistent investing, sensible diversification, a properly drafted will, and regular, open family conversations about money and the odds shift dramatically in your favour.
