Shares vs property in New Zealand, why property still matters, and why most people need more diversification

Property has built a lot of Kiwi wealth, and that story makes sense because your home gives stability, reduces long term housing risk, and often forces consistent saving through a mortgage, which explains why the “Kiwi Dream” still centres on home ownership, with 85% of New Zealanders saying home ownership sits at its heart in Kiwibank’s State of Home Ownership Index.

The problem is not that property is “bad”, the problem is that most households already hold a massive property position by default, so adding more property often pushes the balance sheet into one asset class, one country, and one interest rate cycle, which increases stress when rates rise or when values stop climbing.

The stats show how property heavy we are

In the Stats NZ household net worth asset table for the year ended June 2024, households held about $926.5b in owner occupied dwellings and about $235.0b in other real estate, so roughly $1.16t in property assets.

In that same table, households held about $45.6b in shares in corporations, while pension funds sat around $135.7b.

If you add up all the asset categories in that table, total household assets come to about $2.40t, which means property sits at about 48.5% of household assets, and household property value is about 25x the value of direct shareholdings.

The credit system leans the same way

As at December 2025, registered banks reported total loans of $601.8b and housing loans of $385.6b, so housing sits at about 64% of all bank lending.

The Reserve Bank also notes that more than half of household wealth sits in land and houses, and it points out that the high value of the housing stock reflects rising land values more than investment into new and improved dwellings, which helps explain why property concentration creates bigger economic swings than people expect.

Why shares matter for your plan, and why they matter for New Zealand

Shares represent ownership in businesses that hire, invest, export, innovate, and lift productivity over time, so a stronger sharemarket and deeper capital markets support real economic growth rather than relying on repricing existing land.

MBIE puts it plainly: efficient capital markets provide capital for New Zealand businesses to invest and grow.

Treasury also flags the trade off: high investment in dwellings may crowd out capital investment into productive sectors, even while New Zealand still needs more homes, which is why the goal is balance, not ideology.

New Zealand also runs a relatively small equity market footprint, with stock market capitalisation at 35.69% of GDP in 2024 versus a world average of 69.42%, which fits the idea that we lean harder into property than many countries and we rely less on listed equity markets.

When more Kiwi savings flows into New Zealand shares and funds, liquidity improves and it becomes easier for companies to raise growth capital, and that is one reason NZX frames capital market reforms as a way to unlock access to capital and boost market liquidity and economic growth.

The balanced message for the readers

If you own a home, you already hold a large property exposure, so the smarter move often involves building the rest of your long term wealth through diversified productive assets, including a meaningful allocation to shares across New Zealand and global markets, so one asset class does not decide your future.

Property still plays a role, especially as a home base and, in some cases, as part of a broader plan, yet most households benefit from more diversification because it reduces concentration risk and spreads your future across more drivers of return than house prices and interest rates.
