Cotality's latest suburb-level data shows 79% of suburbs recorded falling standalone house values over the three months to September. More than 750 suburbs fell by over 1%, while roughly 300 of the 1,422 suburbs tracked either held steady or increased. Townhouses were similarly mixed, with 74% of suburbs recording declines.

The latest national data reinforces the point. Property values fell another 0.3% in September, but Hamilton rose 0.4% and Christchurch increased 0.2%, while Auckland fell 0.5% and Wellington dropped 0.7%.

For someone relocating within New Zealand, or returning from Australia, that makes suburb-level research much more useful than asking whether "the NZ property market" is rising or falling.

Why national house-price figures only tell part of the story

National averages are useful for showing the broad direction of the market. Right now that direction is soft.

Cotality's September Housing Chart Pack showed property sales fell 11.6% year-on-year in August, the eighth consecutive annual decline. Elevated listings continued to give buyers meaningful choice, while higher mortgage rates and economic uncertainty kept demand subdued.

But national figures can hide substantial variation underneath.

Auckland and Wellington have been among the softer major markets, while Christchurch has shown greater resilience. Cotality also points to relatively stronger conditions in affordable, farming-supported areas of Canterbury, Southland and Otago.

For a buyer, the practical implication is simple: Don't assume the national trend describes the suburb you're considering.

1. Start with the suburb, not the city average

Even city-wide figures can be too broad.

Auckland is a good example.

Cotality's latest October update shows every major Auckland sub-market declined during September, but the scale varied. Papakura and Rodney fell just 0.1%, while Auckland City, Manukau and the North Shore recorded larger falls of around 0.5% or more.

Within those areas, individual suburbs can vary again.

The same principle applies in Wellington and Christchurch.

Two properties might both be described as being in the "Wellington market", yet differ considerably in:

• Recent price movement

• Supply of comparable homes

• School zones

• Transport connections

• Property type

• Natural-hazard exposure

• Insurance considerations

• Local employment

• Development activity

So before setting a price expectation, look at sales from the immediate area and comparable property type, not just a city-wide median.

2. Look at recent settled sales, not just asking prices

An asking price tells you what the vendor would like.

A settled sale tells you what buyers have actually been prepared to pay.

For each property you're considering, look for several recent comparable sales with similar:

• Land area

• Floor area

• Number of bedrooms

• Age and condition

• Property type

• School zone

• Street or micro-location

A three-bedroom renovated home on a quiet street might not be comparable with a three-bedroom house beside a motorway, even if they're in the same suburb.

In today's slower market, this matters because buyers generally have more time to compare.

Cotality describes current conditions as buyer-friendly, with elevated listings creating significant pricing leverage, although it also notes that most sellers aren't under enough financial pressure for prices to collapse.

3. Check whether you're buying a house or a townhouse market

Property type matters too.

Over the three months to September:

• 79% of standalone-house suburbs recorded falling values.

• 74% of townhouse suburbs recorded declines.

• 22 townhouse markets fell by at least 5%.

That doesn't mean townhouses are inherently better or worse buys.

It means the supply-and-demand dynamics can differ substantially.

A suburb might have limited standalone houses for sale but a large pipeline of new townhouses. In another area, townhouse supply may be tightly constrained.

For newer developments, investigate:

• How many similar properties are being built

• How many are currently listed

• Whether several developers are competing nearby

• Body corporate or residents' association costs where applicable

• Parking and outdoor space

• How recently completed properties have resold

The suburb name alone doesn't tell you that.

4. Pay attention to housing supply

Supply is especially important in a flat market.

A suburb with large numbers of similar properties available gives buyers more alternatives, and potentially more negotiating power.

At a national level, Cotality says elevated listings continue to give buyers much of the pricing power.

But supply varies enormously locally.

Check:

• Current listings

• How long properties remain advertised

• New developments underway

• Whether listings are accumulating or shrinking

• Whether similar houses are repeatedly being repriced

If you've been watching one suburb for several weeks and the same properties remain available, that can tell you something quite different from a suburb where good listings disappear quickly.

5. Don't confuse a falling suburb with a "bad" suburb

This is particularly important in the current market.

Nearly four in five house suburbs fell over the latest three-month period, so declining values alone aren't enough to decide whether an area is attractive or unattractive.

Many declines were small, around 1% or less.

Short-term movements can reflect:

• Higher mortgage rates

• A small number of sales

• Changes in the mix of properties selling

• Increased listings

• Local employment conditions

• Previous over-performance

• Buyer affordability

Likewise, a suburb that has recently risen isn't automatically a better place to buy.

For an owner-occupier, factors such as commute, schools, amenities, property quality and how long you expect to live there may be considerably more important than three months of price movement.

6. Understand what's happening in Auckland, Wellington and Christchurch

Auckland

Auckland remains one of the softer parts of the market.

Values fell another 0.5% in September, with all of Cotality's major Auckland sub-markets declining during the month. In several areas, annual declines are around 3% or more.

For buyers, that generally means greater choice, but suburb differences remain significant.

Wellington

Wellington was the weakest major centre in September, falling 0.7%.

The region has also been affected by softer employment conditions and household caution.

For buyers, insurance, earthquake resilience, slope stability and building quality deserve particular attention alongside price.

Christchurch

Christchurch continues to look more resilient.

Values increased 0.2% in September, following a small rise in August. Cotality has also highlighted the relative resilience of parts of Canterbury.

That doesn't mean every Christchurch suburb is rising, or that buyers should expect continued growth. It does show why applying Auckland or Wellington assumptions to Christchurch can be misleading.

7. Research insurance and natural-hazard risk before making an offer

Suburb research shouldn't stop at price.

In New Zealand, two houses with similar values can carry very different physical and insurance risks.

Depending on the location, investigate:

• Flood zones

• Coastal inundation

• Landslip risk

• Earthquake exposure

• Liquefaction

• Previous weather damage

• Insurability and policy terms

This can affect both your long-term ownership costs and whether a lender will approve the property.

Your solicitor, insurer, building inspector and local council information can all form part of that due diligence.

8. Work backwards from your own budget

A suburb can look affordable based on its median value while still being unsuitable for your finances.

Before narrowing your search, work out:

• Your available deposit

• Likely borrowing capacity

• Monthly repayments

• Council rates

• Insurance

• Maintenance

• Body corporate fees where relevant

• Commuting costs

This is particularly useful for people returning from Australia. Our mortgage repayment calculators can help you quickly model what different purchase prices and loan amounts would mean for your monthly budget.

Auckland may offer different employment opportunities from Christchurch, for example, but the mortgage required can also be considerably different.

The useful comparison is therefore not simply "Which city has cheaper houses?"

It's:

"Where does the combination of property, lifestyle, employment and mortgage cost work for us?"

9. Use market weakness to improve your due diligence, not skip it

The strongest advantage buyers have in today's market may be time.

Property sales were down 11.6% year-on-year in August, listings remain elevated, and Cotality says buyers continue to hold much of the negotiating power.

Use that breathing room.

Before making an unconditional offer, consider:

• Building inspection

• LIM

• Title review

• Insurance

• Finance approval

• Comparable sales

• Planned development nearby

Buying in a softer market can improve your negotiating position, but the quality of the individual property still matters more than shaving another percentage point off the purchase price. Understanding how banks assess mortgage serviceability in New Zealand before you make an offer will also help you move quickly and with confidence when the right property appears.

A practical suburb-research checklist

Before deciding whether an area belongs on your shortlist, check:

Price

• What have genuinely comparable homes sold for recently?

• Are local values rising, falling or broadly flat?

Supply

• How many similar properties are currently available?

• Are listings sitting for longer?

Property type

• Are houses and townhouses behaving differently?

Location

• What are commute times, schools and amenities like?

Future supply

• Are large housing developments planned nearby?

Property risk

• What do the LIM, title, building inspection and insurance position show?

Finance

• Does buying there leave enough repayment and savings buffer?

The aim isn't to identify the suburb most likely to rise next.

It's to understand what you're paying for and what local conditions actually look like.

What's not in the headlines

A flat national market doesn't mean every area is flat.

September's national value decline was only 0.3%, yet Hamilton rose 0.4%, Christchurch rose 0.2%, Auckland fell 0.5% and Wellington fell 0.7%.

Most declining suburbs aren't crashing.

Although 79% of house suburbs fell over the three months to September, many declines were modest. The market remains subdued rather than distressed. For a broader view of what drove conditions across the year, the 2025 NZ property market review covering prices, sales volumes, listings and regional trends provides useful context.

Affordability appears to be influencing regional performance.

Cotality has identified more resilience in some lower-priced and farming-supported parts of Canterbury, Southland and Otago, while higher-priced Auckland and Wellington markets have generally been softer.

Buyers currently have more choice.

High listing levels and weak transaction volumes are giving buyers time to compare properties and negotiate, something that can be especially valuable for people relocating and unfamiliar with the local market.

Our takeaway

New Zealand doesn't have one property market.

It has thousands of local markets influenced by property type, affordability, supply, employment, infrastructure and buyer demand.

The latest data demonstrates that clearly. 79% of house suburbs declined over the three months to September, yet the scale of those falls varied widely, and hundreds of suburbs were flat or rose.

For buyers, particularly those relocating from another city or returning from Australia, that makes suburb research more valuable than trying to decide whether "New Zealand house prices" have reached the bottom. If you're an Australian buyer planning a move, our guide to buying property in New Zealand for Australian buyers covers the key steps, lending requirements and practical considerations involved.

Start with your lifestyle and borrowing budget. Then investigate recent comparable sales, stock levels, local risks and the individual property.
