Housing affordability has been a political and economic issue in both Australia and New Zealand for more than a decade, but the markets are now following noticeably different paths as policy settings and economic conditions diverge.

Australian property prices have remained relatively flat over the past 18 months after the sharp corrections of 2022-2023. Sydney and Melbourne prices are roughly 10-12% below their peaks, while Brisbane and Perth have actually appreciated. The national picture masks significant regional variation. Mortgage rates remain elevated with standard variable rates around 6.5-6.8%, well above the emergency lows of 2020-2021.

New Zealand experienced more dramatic corrections. Auckland property prices fell approximately 18% from peak to trough before stabilizing in mid-2025. Wellington saw even steeper declines of around 22%. The Reserve Bank of New Zealand’s aggressive interest rate increases hit the heavily mortgaged New Zealand market particularly hard. Current mortgage rates sit around 6.8-7.2%, slightly higher than Australia.

The policy response differs significantly. Australia’s various state governments have implemented different approaches—New South Wales allowing more density, Victoria focusing on social housing, Queensland pushing infrastructure-led development. The federal government has set ambitious building targets but lacks direct implementation levers. Progress has been uneven.

New Zealand’s government has taken a more centralized approach through the National Policy Statement on Urban Development, forcing councils to zone for greater density and removing many planning restrictions. The impact is starting to show in building consent numbers, which are running above the ten-year average despite higher interest rates.

Foreign investment restrictions differ markedly. New Zealand maintains relatively strict controls on foreign property purchases, with most foreign buyers requiring government approval. Australia has tightened foreign investment rules for established properties but maintains more open access for new construction. This affects both demand and development funding patterns.

Construction sector dynamics are creating different supply responses. Australia’s construction sector is dealing with multiple large builders entering administration, creating completion risk for buyers and supply disruption. New Zealand’s smaller market and different industry structure has avoided the same level of builder distress, though cost pressures are intense.

Migration patterns significantly impact housing demand. Australia’s strong immigration recovery post-COVID has added substantial housing demand, particularly in Sydney and Melbourne. Net migration to Australia reached nearly 500,000 in 2023-24. New Zealand’s migration has also been strong but on a smaller absolute scale. The compositional difference matters—Australia is attracting more family migration while New Zealand sees more temporary work visas.

Rental markets tell different stories. Australian rental vacancy rates in major cities are extremely low, with Sydney and Melbourne below 2%. This creates intense competition for rental properties and rapid rent growth. New Zealand’s rental market is somewhat less constrained, partly due to the larger property price corrections prompting some investors to sell rather than continue renting out properties.

Taxation treatment of property investment differs in important ways. Australia’s negative gearing provisions and capital gains tax discount for individuals create tax incentives for property investment. New Zealand removed mortgage interest deductibility for investors in 2021 (though the current government is gradually reinstating it), reducing the tax advantage of property investment. These different settings influence investor demand.

First home buyer segments are experiencing different support levels. Australia’s First Home Super Saver Scheme and various state-based grants provide some assistance, though whether these subsidize prices more than help buyers is debatable. New Zealand’s First Home Grant and HomeStart loans offer more targeted support but help fewer people given stricter eligibility criteria.

The build-to-rent sector is emerging differently in each market. Australia is seeing significant institutional investment in build-to-rent developments, driven partly by tax settings and partly by demand from renters priced out of ownership. New Zealand’s build-to-rent sector is smaller and less developed, though growing.

Social housing supply represents a significant policy difference. Australia’s social housing stock has declined as a percentage of total housing over recent decades, and new construction hasn’t kept pace with population growth. New Zealand has significantly increased social housing investment in recent years, though from a low base. Neither country is close to meeting social housing demand.

Regional markets show fascinating divergence. Australian regional markets that boomed during COVID (Gold Coast, Sunshine Coast, Byron Bay, Southern Highlands) have seen corrections but remain well above pre-pandemic levels. New Zealand’s regions followed similar patterns but with more severe corrections in tourist-dependent areas like Queenstown.

Demographic factors are starting to matter more. Australia’s larger population and continued strong immigration suggest sustained housing demand. New Zealand’s smaller population base and lower birth rate create different long-term demand dynamics. Both countries face aging populations wanting to downsize, but suitable downsizing stock is limited.

The investor market is particularly interesting. Australian property investors have faced rising interest rates but many locked in low fixed rates in 2020-2021, providing temporary protection. As these fixed terms expire, some investors are selling, adding to supply. New Zealand investors experienced cash flow pressure earlier due to higher variable rate prevalence.

Looking forward, the trajectories may continue diverging. Australia faces a supply challenge that’s difficult to solve quickly given construction sector issues and infrastructure constraints. Prices may stabilize or even appreciate again as supply fails to meet demand. New Zealand’s more aggressive planning reform may actually deliver meaningful supply increases over the next 3-5 years, keeping price pressure contained.

Affordability metrics remain dire in both countries. Median house price to median income ratios sit above 8 in Sydney and Auckland, well above the 3-4 considered affordable. First-time buyers without family support face enormous challenges accumulating deposits and servicing mortgages at current prices and rates.

The political sensitivity around housing means policies will continue evolving. Both countries face the difficult reality that improving affordability for buyers means reducing wealth for existing property owners, who represent a majority of voters and have substantial political influence. Resolving this tension will define housing policy for years to come.

For businesses, housing affordability impacts labor markets. Expensive housing makes it harder to attract and retain workers in major cities. Some companies are adapting by offering more remote work or establishing offices in more affordable locations. The economic productivity impacts of housing unaffordability are significant and under-appreciated.
