For many Australians and New Zealanders, the property market across the Tasman has become increasingly attractive. Australians often wonder whether New Zealand offers more affordable housing or a simpler lifestyle, while New Zealanders continue to see Australia as a destination offering larger cities, stronger employment opportunities and, in many regions, comparable housing values.

Despite their close relationship under the Trans-Tasman Travel Arrangement, buying property in either country is governed by different laws and investment rules.

Property prices: Australia versus New Zealand

Both countries have experienced substantial increases in residential property values over the past two decades, although the pace has varied.

Australia's largest cities—particularly Sydney and Melbourne—remain among the most expensive housing markets in the Asia-Pacific region. Brisbane, Perth and Adelaide have also recorded strong growth in recent years as interstate migration and population growth have increased demand.

New Zealand experienced one of the world's fastest rises in house prices during the pandemic before values softened as interest rates increased. Auckland remains the country's most expensive city, while Wellington and Christchurch have seen more moderate pricing.

When comparing major cities:

• Sydney generally remains more expensive than Auckland.
• Melbourne and Auckland are often broadly comparable depending on property type.
• Regional New Zealand can offer lower entry prices than many Australian coastal regions.
• Australia's mining and lifestyle regions continue to experience periods of rapid appreciation driven by local economic conditions.

Overall, neither country can now be regarded as a "cheap" property market. Affordability remains a significant political and economic issue on both sides of the Tasman.

Can Australians buy property in New Zealand?

The answer is generally yes.

Australians receive special treatment under New Zealand's overseas investment rules because of the close economic relationship between the two nations.

In most circumstances, Australian citizens who are living in New Zealand or hold the appropriate residency status can purchase residential property in much the same way as New Zealand citizens.

However, investment rules become more complex for Australians who are not ordinarily resident in New Zealand, particularly following reforms introduced in 2018 that restricted purchases of existing homes by many foreign buyers.

Professional legal advice is recommended before committing to a purchase.

Can New Zealanders buy property in Australia?

Generally, yes.

New Zealand citizens living in Australia enjoy significant rights under the Special Category Visa arrangements and are generally able to purchase residential property without many of the restrictions that apply to other foreign buyers.

However, New Zealand citizens who are not resident in Australia may still need to consider Australia's foreign investment framework and any applicable approval requirements.

As with any international purchase, buyers should obtain legal and taxation advice before proceeding.

Property valuation: Australia

Australia has also seen significant changes in how property values are assessed for taxation and government purposes.

Many state governments now rely on regularly updated land valuations and mass appraisal techniques rather than infrequent manual assessments. Digital sales data, comparable market transactions and computer-assisted valuation models play a much greater role than they did a decade ago.

These valuations influence:

• Land tax
• Council rates
• State government charges
• Some compulsory acquisition processes

They do not necessarily represent the price a property would achieve if offered for sale today.

New Zealand's approach

New Zealand also operates a nationwide valuation system through local councils.

Properties receive a Rating Valuation (RV), commonly updated every three years. The RV assists councils in calculating local authority rates but is not intended to represent an exact current market value.

Buyers and sellers typically rely on recent comparable sales, registered valuations and market conditions when negotiating purchase prices.

Like Australia, New Zealand increasingly uses sophisticated data analysis alongside traditional valuation methods.

Shared challenges

Although their systems differ, Australia and New Zealand face remarkably similar housing pressures:

• Population growth in major cities.
• Limited housing supply.
• High construction costs.
• Interest rate sensitivity.
• Affordability challenges for first-home buyers.
• Political debate over taxation, planning laws and housing policy.

Both governments continue searching for ways to increase housing supply without creating instability in their property markets.

The Australasian View

Australia and New Zealand share far more than geography. Their housing markets are increasingly influenced by similar economic forces, and citizens of each country continue to view the other as a realistic place to live, work and invest.

For prospective buyers, the opportunity exists on both sides of the Tasman, but familiarity should not be confused with simplicity. Taxation, residency requirements, financing and valuation systems differ in important ways.

The next phase of trans-Tasman property investment is unlikely to be driven solely by house prices. Lifestyle, employment opportunities, demographic change and government policy may prove just as influential as the cost of the home itself.
