An overlooked change: New Zealand is entering the era of monthly inflation data, as three housing market signals emerge

For most people, a reform recently announced by Stats NZ probably does not seem like the kind of news that would spark widespread discussion.

After all, compared with rising or falling house prices, changes in mortgage rates or adjustments to the official cash rate (OCR), an upgrade to economic statistics sounds more like something only economists and policymakers would care about.

Yet this change could be far more significant than many people realise.

Under the newly announced plan, New Zealand will begin publishing a monthly Consumers Price Index (CPI) in 2027, alongside more monthly indicators of economic activity, while gradually improving core economic statistics such as GDP and the balance of payments.

This means New Zealand is about to move beyond its longstanding reliance on quarterly inflation data and enter a new phase in which economic changes can be monitored more frequently.

On the surface, this is a statistical reform.

At a deeper level, however, it reflects a reality: the economy is moving ever faster, and markets, businesses and policymakers increasingly need information in real time.

As this change approaches, New Zealand’s property market is also sending some new signals worth watching.

From improving consumer confidence and changing household borrowing behaviour to an increasingly marked divergence in house price performance across the country, some easily overlooked shifts are quietly taking place.

What does the move from quarterly to monthly inflation data mean?

New Zealand has long been among the few OECD countries that still publish their consumer price index quarterly.

This means that whether the Reserve Bank of New Zealand is setting monetary policy or markets are forecasting interest rates, they must wait three months for each complete set of inflation data.

When economic conditions are changing rapidly, that frequency often falls short of providing timely information.

Over the past few years, New Zealand has experienced high inflation after the pandemic, aggressive interest rate rises and a property market correction. During that period, many economists noted that slow data updates made it harder to assess the economy’s direction.

Former Reserve Bank governor Adrian Orr repeatedly voiced public support for monthly inflation data, arguing that more timely information would help assess price pressures and economic conditions accurately.

Once monthly inflation data is introduced, markets are likely to react even faster to economic changes.

This is particularly important for the property market.

Interest rates have been among the most important influences on house prices in recent years, and changes in interest rates depend heavily on inflation data.

The first signal: consumer confidence is slowly recovering

New Zealand consumer sentiment has shown some positive changes over recent months.

The latest survey by independent economist Tony Alexander shows that in April this year, a sizeable proportion of respondents still planned to cut their spending over the coming months, but by June, that pessimism had eased considerably.

This does not mean consumers have returned to spending freely.

Grocery bills, insurance premiums, energy costs and mortgage payments continue to put pressure on many households.

But an important change is emerging in the market:

More people are beginning to feel that the hardest period may be over. For the property market, this shift often deserves more attention than house prices themselves, because housing is fundamentally a market that depends heavily on confidence.

When people worry about the economic outlook, they postpone plans to buy a home. As concerns about jobs, income and the future begin to ease, demand for homes often picks up first.

Over the past three years, one of the defining features of New Zealand’s housing market has been a wait-and-see approach.

That hesitation now appears to be gradually easing.

The second signal: few people are buying, but more are borrowing

The latest Reserve Bank of New Zealand data shows that banks approved more than 21,000 residential mortgages in April this year, an increase of more than 10% from a year earlier.

At first glance, this seems to suggest the mortgage market is recovering rapidly. A closer look, however, reveals a more complicated picture. The number of new loans for property purchases actually fell slightly from the same period last year.

Mortgage top-ups are recording the fastest growth.

In April this year, existing homeowners increasing their borrowing accounted for nearly half of all new mortgage approvals.

In other words, the most active mortgage customers are people who already own property, rather than those preparing to buy.

More homeowners are using the equity in their properties to apply for additional bank funding for renovations, repayment of other debts, or future investment and spending.

This does not necessarily mean the property market has fully recovered.

But it does point to another development worth watching: households are becoming more confident about the future than they were a year ago.

Meanwhile, around a quarter of new mortgage lending by value comes from customers refinancing with a different bank.

This shows that competition among banks for mortgage business remains intense in the current market.

For borrowers, this generally means more room to negotiate and more opportunities to secure favourable interest rates.

The third signal: regional housing markets are diverging faster

Where New Zealand’s property market once tended to rise or fall in unison nationwide, divergence is now its defining feature.

The latest Cotality and QV data shows that house prices nationwide remain broadly flat.

But differences in performance between regions are widening.

Over the past year, standalone house prices rose by more than 10% in over 20 suburbs nationwide, with the vast majority concentrated in regions such as Southland and the West Coast.

These markets share several characteristics:

Relatively affordable house prices;

Stable local economic performance;

Strong support from agriculture and export industries;

Continued activity among first-home buyers and small investors.

Auckland, by contrast, continues to face significant pressure on prices.

Although market activity has improved from last year, house prices overall remain around 23% below their record peak in early 2022.

Some areas have even continued to record substantial falls over the past year.

Prices in areas such as Wiri, Wesley and Glen Innes, for example, are still adjusting.

Supply is one important reason for this divergence.

Auckland has seen substantial residential development in recent years, with new homes continuing to come onto the market while buyer demand has recovered relatively slowly.

When buyers have plenty of choice, price growth is naturally constrained.

Regional markets with limited supply and a more stable employment and industry base, meanwhile, have shown greater resilience in house prices.

This also means future property market opportunities and risks will increasingly depend on the particular location, rather than a simple nationwide movement in the same direction.

The housing market in the data era may look different

Over the past few years, many people have been waiting for an answer to one question:

When will house prices start rising again?

Over the coming years, however, the market may need a different perspective. The key question may shift from whether house prices will rise to which areas will recover first and which will remain under pressure.

As monthly inflation data is rolled out, markets will be able to monitor economic changes more promptly.

Changes in consumer confidence, inflation pressures, employment conditions and interest rate expectations could all feed through to the property market faster than before.

For buyers, this means the pace of market change could accelerate.

For investors, it also means future opportunities will depend more on choosing the right regions than simply waiting for the entire market to rise together.

Observations and reflections

New Zealand’s property market has undergone a deep correction over the past three years.

Although house prices have yet to rebound across the country, changes are already taking place within the market.

Consumer confidence is improving, household borrowing activity is gradually increasing, and differences in regional performance are becoming more pronounced.

Meanwhile, New Zealand is building a more timely and transparent system of economic statistics.

Individually, these changes may seem unremarkable. Together, however, they could signal that the property market is entering a new phase.

New Zealand’s housing market may be moving beyond an era in which all regions rise and fall together, towards a new cycle shaped more by economic fundamentals, population movements and differences in regional development.

For buyers and investors, the focus now needs to extend beyond the outcome of the next OCR meeting to where these quiet changes will ultimately direct capital, people and opportunities.
