Whether you own a house in Christchurch, this guide is designed to help you understand your real risks and how to protect your most valuable asset. Our guide covers:
Know This First - House Insurance is Getting More Expensive and Harder to Obtain
Consumer's 2025 report into house insurance, which is free to download and read, is arguably the most in-depth research into home insurance costs available. It saw contributions from the Christchurch City Council, Natural Hazards Commission and insurance bodies, with extensive findings, including:
- Christchurch homeowners face unique insurance challenges, and policy costs vary significantly across insurers.
- Christchurch isn't like the rest of New Zealand when it comes to house insurance - the city is still dealing with the aftermath of the 2010/2011 earthquakes, navigating complex TC land categories, and managing properties that range from brand new rebuilds to damaged homes still awaiting repairs.
- The earthquakes changed everything. Over 170,000 properties were damaged, entire suburbs were red-zoned, and the city's land was divided into technical categories that determine building viability.
- Add in liquefaction risk that insurers now understand properly, flooding in areas that never flooded before the quakes, lateral spread near rivers, and the reality that Christchurch sits on a swamp barely above sea level, and it's clear Christchurch homeowners face insurance challenges no other city understands.
- Our research is focused on cutting through the confusion to give Christchurch homeowners what's needed - suburb-specific risk assessments based on TC land categories and strategies to ensure homeowners are genuinely protected when the next significant event hits.

Know This First - House Insurance is Getting More Expensive and Harder to Obtain
Consumer's 2025 report into house insurance, which is free to download and read, is arguably the most in-depth research into home insurance costs available. It saw contributions from the Christchurch City Council, Natural Hazards Commission and insurance bodies, with extensive findings, including:
- House insurance costs have skyrocketed 916% since 2000 - the highest increase of any product tracked by New Zealand's Consumer Price Index over 25 years, massively outpacing inflation.
- By 2035, many New Zealanders may struggle to obtain home insurance due to climate change risks, as insurers are already retreating from high-risk areas globally and much of New Zealand's risk is re-insured overseas.
- Up to 700,000 people and 411,516 buildings in New Zealand are at risk of river flooding, with an additional 72,000 people exposed to severe coastal flooding.
- 85% of New Zealand homes could be underinsured by an average of 28%, creating a potential insurance gap of $184 billion (now $242 billion) that could devastate families after disasters.
- In 2023 alone, extreme weather events cost insurers $3.8 billion - eclipsing all previous records and directly driving premium increases across the country.
- Australian-owned insurers IAG and Suncorp control 92% of NZ's insurance market with insurers such as State, AMI and AA Insurance (part-owned by Suncorp), and appear to make higher profit margins here than in Australia.
- The cost of insurance has become the fourth biggest financial concern for New Zealanders, behind only housing, food, and household debt, with 17% dropping house insurance due to the cost.

MoneyHub Founder and Head of Research Christopher Walsh Explains Why House Insurance is Too Important to Get Wrong:
"House insurance is highly property-specific, and we strongly encourage you to verify all details independently to ensure you select the best policy for your needs. Both sum insured and area replacement policies have unique benefits and risks. We suggest obtaining quotes for both options from multiple insurers to make an informed decision. Before buying any insurance policy, always review the policy documents, check your property's specific risks and make sure you understand the cover you're buying. Underestimating rebuild costs or skipping annual reviews can lead to significant financial exposure. While this guide highlights the benefits of area replacement for its ability to mitigate rebuild cost risks, we recognise that sum insured policies can be a viable and cost-effective option for many homeowners. It's essential to make sure your sum insured is accurate and regularly updated". |

The Major Must-Know Risks for Christchurch Properties and the Impact of Climate Change
Canterbury Regional Council hazard maps and media stories only give you a limited appreciation of the significant issues that homeowners across greater Christchurch face. We outline the major risk areas to help you understand it's essential to buy the most appropriate insurance for your home.
1. Land Categories and Ongoing Settlement
Christchurch's TC land classification system arguably drives insurance complexity. While the earthquakes were over a decade ago, properties continue to experience differential settlement, especially on TC3 land. Current risk factors include:
Our View: Many properties show new cracks and movement years after repairs were completed. Insurance companies now understand these risks better and price accordingly - TC3 properties face significantly higher premiums or outright decline.
2. Flooding (Christchurch's New Normal)
Post-earthquake land settlement has fundamentally changed Christchurch's flood risk. Areas that never flooded now do regularly. Problem zones include:
Our View: The earthquakes dropped some areas by up to a metre. Combined with rising groundwater and sea levels, flooding is now Christchurch's primary insurance concern. The March 2023 floods showed this isn't improving.
3. Liquefaction Risk Remains
While less dramatic than 2011, liquefaction risk hasn't disappeared. Any moderate earthquake still triggers it in:
Our View: Insurers haven't forgotten the high costs from liquefaction claims. Properties in these zones face higher premiums and more stringent policy conditions, even for well-performing TC1 land nearby.
4. Coastal Hazards and Erosion
Christchurch's coastline faces multiple threats. Rising seas meet sinking land, creating accelerating problems for:
Our View: Some coastal properties are effectively uninsurable for natural hazards. Others face premiums that make holding the property uneconomic. Managed retreat is actively discussed for several areas.
1. Land Categories and Ongoing Settlement
Christchurch's TC land classification system arguably drives insurance complexity. While the earthquakes were over a decade ago, properties continue to experience differential settlement, especially on TC3 land. Current risk factors include:
- TC3 properties requiring specific foundations and ongoing monitoring
- TC2 land with moderate liquefaction risk during any seismic activity
- Properties near rivers are subject to lateral spread
- Areas of ongoing settlement causing structural damage
Our View: Many properties show new cracks and movement years after repairs were completed. Insurance companies now understand these risks better and price accordingly - TC3 properties face significantly higher premiums or outright decline.
2. Flooding (Christchurch's New Normal)
Post-earthquake land settlement has fundamentally changed Christchurch's flood risk. Areas that never flooded now do regularly. Problem zones include:
- Flockton Basin and St Albans (the "Flockton Lake" phenomenon)
- Mairehau and Shirley (impacted by land level changes)
- Southshore and South New Brighton (tidal flooding)
- Heathcote Valley and Woolston
Our View: The earthquakes dropped some areas by up to a metre. Combined with rising groundwater and sea levels, flooding is now Christchurch's primary insurance concern. The March 2023 floods showed this isn't improving.
3. Liquefaction Risk Remains
While less dramatic than 2011, liquefaction risk hasn't disappeared. Any moderate earthquake still triggers it in:
- Eastern suburbs (Bexley, Parklands, Aranui)
- Kaiapoi and surrounding areas
- Parts of Halswell and Wigram
- Richmond and St Albans river corridors
Our View: Insurers haven't forgotten the high costs from liquefaction claims. Properties in these zones face higher premiums and more stringent policy conditions, even for well-performing TC1 land nearby.
4. Coastal Hazards and Erosion
Christchurch's coastline faces multiple threats. Rising seas meet sinking land, creating accelerating problems for:
- Southshore and South New Brighton (erosion and inundation)
- Sumner and Redcliffs (rockfall and erosion)
- Brooklands and Spencerville (already partially red-zoned)
- Waimairi Beach and North Beach
Our View: Some coastal properties are effectively uninsurable for natural hazards. Others face premiums that make holding the property uneconomic. Managed retreat is actively discussed for several areas.
Understanding the Factors Driving Christchurch's Higher Insurance Costs
Christchurch's building costs are increasing based on cost data filed by builders with Christchurch City Council. This is due to many reasons:
However, after any natural disaster, these costs spike 40% or more as demand overwhelms supply, as evidenced by recent examples explained in our Natural Disaster Home Insurance guide.
Our View: Christchurch already experienced this after 2011 - rebuild costs doubled, builders were booked for years, and homeowners paid whatever it took. The city still has fewer qualified builders than before the earthquake, meaning any significant event will create immediate shortages and price spikes. Our guide to sum insured vs area replacement explains how each option insures for rebuild costs.
- TC3 land requiring specialised foundations
- Geotechnical testing and monitoring requirements
- Higher standards for liquefaction mitigation
- Limited pool of experienced builders post-rebuild
- Materials shortage as the city continues rebuilding

Suburb-Specific Considerations - Our View of Christchurch Right Now
There is a lot of data, and our summary below is subjective and not intended as insurance advice. What's important is that homeowners gather as many quotes as possible to get the best policy at an affordable price - comparing insurer by insurer is the only way to do this, but it’s also essential to understand the difference of cover offered by sum insured vs area replacement cover.
High-Risk Zones include:
Medium-Risk Zones include:
Lower-Risk Zones include:
High-Risk Zones include:
- TC3 land areas: Bexley, Parklands, Horseshoe Lake, Brooklands
- Flood-prone: Flockton Basin, St Albans, Mairehau, Heathcote Valley
- Coastal erosion: Southshore, South New Brighton, Sumner, Redcliffs
- Liquefaction zones: Aranui, Wainoni, Dallington, Avonside
Medium-Risk Zones include:
- TC2 land with moderate liquefaction potential
- Properties near waterways (Avon and Heathcote rivers)
- Older suburbs with deferred maintenance (Richmond, Linwood)
- Hill suburbs with rockfall risk (Cashmere, Huntsbury)
Lower-Risk Zones include:
- Western suburbs on good ground: Fendalton, Merivale, Ilam
- Newer developments with modern infrastructure: Wigram Skies, Prestons
- TC1 land away from waterways: Burnside, Bishopdale, Papanui
- Well-drained elevated areas: Upper Cashmere, Westmorland
Christchurch House Insurance Coverage Options - Area Replacement vs Sum Insured
Option 1: Sum Insured: The Standard (Risky) Option
Most Christchurch homeowners have sum insured policies. You calculate an estimate of replacement costs using a house insurance calculator - say $800,000 - and hope it's enough. However, problems can arise - which we outline below:
1) Christchurch Homeowners Consistently Underestimate
2) Online Calculators Don't Work Perfectly for Christchurch
This is because generic calculators can't account for:
The Post-Disaster Spike
Your $750,000 sum insured assumes normal market conditions. Christchurch already learned this lesson the hard way. After the earthquakes:
Suddenly, your $750,000 sum insured buys you $450,000 worth of building during surge periods after a natural disaster.
Option 2: Area Replacement: Arguably Essential for Christchurch Properties
Area replacement works differently - your coverage is based on floor area (say 180 square meters) multiplied by current rebuild costs. When disaster strikes and costs spike, you're paid the reasonable costs to rebuild your home, like for like.
Why it Matters More in Christchurch
Most Christchurch homeowners have sum insured policies. You calculate an estimate of replacement costs using a house insurance calculator - say $800,000 - and hope it's enough. However, problems can arise - which we outline below:
1) Christchurch Homeowners Consistently Underestimate
- Average underinsurance: We estimate this to be at least 30-40% of homes currently using sum insured
- TC3 properties: We estimate at least 60% are underinsured due to foundation requirements
- Our View: If you haven't updated your sum insured since the rebuild boom ended, you're almost certainly short
2) Online Calculators Don't Work Perfectly for Christchurch
This is because generic calculators can't account for:
- TC3 foundation systems (can add $100,000+)
- Geotechnical requirements specific to your land
- Ground improvement costs for liquefaction-prone areas
- Christchurch's specific compliance costs post-earthquake
The Post-Disaster Spike
Your $750,000 sum insured assumes normal market conditions. Christchurch already learned this lesson the hard way. After the earthquakes:
- Labour costs jumped 50-80%
- Materials became impossible to source
- Wait times meant years of temporary accommodation
- New building standards added massive costs
Suddenly, your $750,000 sum insured buys you $450,000 worth of building during surge periods after a natural disaster.
Option 2: Area Replacement: Arguably Essential for Christchurch Properties
Area replacement works differently - your coverage is based on floor area (say 180 square meters) multiplied by current rebuild costs. When disaster strikes and costs spike, you're paid the reasonable costs to rebuild your home, like for like.
Why it Matters More in Christchurch
- The city has already experienced massive rebuild cost volatility
- TC land categories create unpredictable foundation costs
- Many properties have unique post-earthquake repairs that are hard to value
- Future events will trigger immediate builder shortages (many left after the rebuild)

Summary
Compare Policy Details
- If you're serious about switching insurers, or want to negotiate a better deal with your existing one, compare compare compare. It's the only way to have any bargaining power when it comes to bringing down the cost of house insurance.
- Useful resource: We've compared house insurance policies side-by-side to make it easier to see where you're covered, and where you're not. Download our policy comparison table in XLS (Google Sheets).
- Why MAS Pricing Isn't Included: MAS offers area replacement policies, which are priced based on your property's floor area and rebuild costs, unlike sum insured policies that use a fixed dollar amount. Because rebuild costs vary significantly by property size, location, and construction type (e.g., heritage features, coastal specifications), providing generalised pricing for MAS would be misleading. For accurate pricing, we suggest getting a quick estimate with MAS estimate directly or a full quote, as well as other insurers like Tower and Initio, to compare coverage and costs specific to your property.
- For Sum Insured Options: Tower and Initio consistently deliver the best combination of price and comprehensive benefits. Both offer excellent coverage within the sum insured model - just remember you're still carrying the rebuild cost risk.

Compare House Insurance Quotes With Our Three Trusted Insurers - MAS, Tower and Initio - Different Coverage, Different Risks
The Uncomfortable Truth: Many New Zealand homeowners have sum insured and are unknowingly carrying a six-figure liability. They're saving $20-$30/month but risk losing $200,000+ if disaster strikes and building costs spike further which means their sum insured estimate is too low. Our guide to Area Replacement vs Sum Insured explains more.
MoneyHub's Position: After Christchurch showed us 40% building cost spikes, and with climate events becoming routine, area replacement isn't "premium" insurance - it's actual insurance. Sum insured makes you the insurer of last resort, and while area replacement may cost 10-20% more, we believe that insurance that leaves you $200,000 short isn't good value at any price.
The cheapest insurance can be expensive if it doesn't cover the cost of rebuilding. The best insurance - the kind that actually protects your biggest asset - is worth every cent.
Compare all three today - the 3-6 minutes it takes could save you $200,000 tomorrow - visit MAS, Tower and Initio to see live quotes from trusted insurers.
- Get a MAS Area Replacement Estimate (1-2 Minutes): Pays full rebuild costs even if they spike 40% after disaster

6) Southern Suburbs
Halswell/Wigram/Aidanfield
Hillmorton/Hoon Hay/Spreydon
Woolston/Opawa/Waltham
1) Eastern Suburbs - TC3 Land
CentralBexley/Parklands/Queenspark
- Risk factors: These suburbs sit on TC3 land with severe liquefaction risk. Many properties still show ongoing settlement despite repairs. The water table is barely below ground level.
- Key concern: Foundation requirements can add $150,000+ to the cost of any rebuild. Properties here need specific engineering solutions that standard insurance calculators don't capture. Some streets have been abandoned entirely.
Aranui/Wainoni/Avondale
- Risk factors: A Mix of TC2 and TC3 land with high deprivation, adding complexity to insurance. Many properties have deferred maintenance from earthquake damage that was cash-settled rather than repaired.
- Insurance reality: Some insurers won't touch these suburbs. Those that charge premiums that can exceed $5,000 annually for modest homes. A history of multiple claims makes it harder to obtain coverage.
New Brighton
- Risk factors: Coastal erosion and liquefaction. Properties face storm surge, rising seas, and ground that turns to soup in any shake. Some areas have dropped over a metre since 2011.
- Key concern: These suburbs face insurance retreat within 5-10 years. Coastal hazard zones are expanding annually. Properties that survived the earthquakes may not survive the insurance market.
2) Northern Suburbs - The Flood Zone
St Albans/Mairehau/Flockton
- Risk factors: The infamous "Flockton Lake" appears whenever it rains heavily. Post-earthquake land settlement created new low points where water pools. Stormwater systems can't cope.
- Recent issues: The May 2021 floods caused water to enter hundreds of homes. It happened again in 2022 and 2023. Each event makes it harder to obtain insurance.
- Key concern: Properties here are subject to annual flooding. Insurers effectively blacklist some addresses after multiple claims.
Papanui/Bishopdale/Northlands
- Risk factors: Generally good ground (TC1), but aging infrastructure and increased rainfall are causing surface flooding.
- Insurance impact: Premiums have doubled in five years as insurers recognise flood risk extends beyond traditional zones.
Belfast/Marshland/Spencerville
- Risk factors: Semi-rural areas with high water tables, poor drainage, and some TC3 land. Spencerville is partially red-zoned. Limited services increase rebuild complexity.
- Key concern: Distance from the city centre means higher rebuild costs and longer wait times. Some properties have septic systems that fail in liquefaction events.
3) Central City
CBD/Four Avenues
- Risk factors: Mix of new builds and older structures. Body corporate complications for apartments. Some buildings still have unresolved earthquake damage. High crime affecting contents claims.
- Key concern: The rebuild created a patchwork of building standards. Your modern apartment might share walls with an earthquake-damaged structure.
Richmond/St Albans South
- Risk factors: Older housing stock on variable ground conditions. River proximity creates lateral spread risk. Many properties need foundation work, but owners can't afford it.
- Insurance reality: Insurers want detailed engineering reports before offering coverage. A bad report can make your property uninsurable.
Addington/Sydenham
- Risk factors: Mix of residential and light industrial. Some TC2/TC3 land near Hagley Park. Flooding where you wouldn't expect it, due to changes in ground levels.
- Rebuild challenges: Commercial neighbours can complicate residential insurance claims. Contamination issues from former industrial use.
4) Hill Suburbs
Cashmere/Huntsbury/Westmorland
- Risk factors: Rockfall risk was dramatically demonstrated in 2011. Some properties still have boulder protection structures. Access challenges on steep sites.
- Key concern: While the rocks have been cleared, the cliff faces remain unstable. Insurance specifically excludes some addresses from rockfall coverage.
Sumner/Redcliffs/Mount Pleasant
- Risk factors: Spectacular seaside location with spectacular problems. Rockfall from above, erosion from below, and earthquake risk all around.
- Insurance reality: Some clifftop properties are uninsurable. Others face premiums exceeding $8,000 annually. Several streets have been abandoned.
Port Hills/Governors Bay
- Risk factors: Remote location with single access routes. Fire risk in dry summers. Steep sites require significant engineering.
- Rebuild challenges: Distance and access add 30-40% to standard rebuild costs. After the Port Hills fires, insurers are nervous about fire risk.
5) Western Suburbs - The "Safe" Zone
Fendalton/Merivale/Strowan
- Risk factors: Generally excellent ground conditions (TC1), but some river proximity issues. Older character homes need earthquake strengthening.
- Insurance advantage: These suburbs have the most competitive premiums in Christchurch. Multiple insurers compete for these lower-risk properties.
Ilam/Riccarton/Upper Riccarton
- Risk factors: Mostly TC1 land with good drainage. University proximity means student rental issues. Some flood risk near the Waimairi Stream.
- Key concern: While technically low-risk, premiums still reflect Christchurch's overall risk profile. You pay more just for being in Christchurch.
Burnside/Harewood/Bishopdale
- Risk factors: Solid ground, newer infrastructure, but increased surface flooding as the climate changes. Airport noise doesn't affect insurance, but it affects property values.
- Insurance reality: Best insurance rates in Christchurch, but still 20-30% higher than comparable properties in other cities.
6) Southern Suburbs
Halswell/Wigram/Aidanfield
- Risk factors: Newer developments on former farmland. Some areas have high water tables. Rapid growth means infrastructure struggles to keep pace.
- Recent issues: Flooding in areas marketed as flood-free. Some TC2 land wasn't disclosed to buyers who discovered it when seeking insurance.
Hillmorton/Hoon Hay/Spreydon
- Risk factors: Mix of older and newer properties. The proximity of the Heathcote River creates flood risk. Some unexpected TC3 patches.
- Key concern: These middle-ring suburbs are seeing premium increases as insurers recognise previously unmapped risks.
Woolston/Opawa/Waltham
- Risk factors: Industrial history means potential contamination. Heathcote River flooding. A mix of TC categories creates confusion about risk levels.
- Insurance impact: Variable premiums depending on exact location. One street might be fine, the next faces massive loadings.

Dangerous Shortcuts to Avoid include:
- Underestimating rebuild costs to lower premiums
- Excluding contents to save money
- Ignoring flood risk to get coverage
- Skipping annual reviews
The Bottom Line for Christchurch Homeowners Looking for Robust and Affordable House Insurance
Christchurch homeowners face ongoing challenges - living with TC land categories, managing properties that range from brand new to earthquake-damaged, dealing with new flood risks from settlement, all while insurance premiums climb annually as insurers better understand Canterbury's complex risk profile.
We believe many Christchurch homeowners are significantly underinsured. Sum insured policies might leave you hundreds of thousands short, especially for TC3 properties where foundation costs alone can exceed standard calculations. The city has already experienced what happens when demand overwhelms supply - rebuild costs doubled, and homeowners waited years.

Frequently Asked Questions
Why is Christchurch house insurance so much more expensive than in most other parts of New Zealand?
Christchurch insurance costs reflect the ongoing reality of living in a post-earthquake city. The 2010/2011 earthquakes fundamentally changed how insurers view Canterbury risk. TC3 land requires specialised foundations, which can add $150,000+ to rebuild costs. The city has identified liquefaction risk affecting thousands of properties. Rebuild costs run $3,000-4,500/sqm (versus $2,200+ elsewhere) due to enhanced engineering requirements.
The earthquakes generated over $40 billion in claims - insurers haven't forgotten. Many properties have unresolved damage or ongoing settlement issues. The limited pool of experienced builders means any new event creates immediate shortages and price spikes. Add in new flood risks from changed ground levels, and you understand why Christchurch premiums are 30-50% higher than comparable cities.

Is my area considered high risk for insurance?
High-risk suburbs, where you can likely expect 50-100% higher insurance costs, include:
- TC3 land zones: Bexley, Parklands, Queenspark, Horseshoe Lake, Brooklands, Spencerville
- Flood-prone: Flockton Basin, St Albans, Mairehau, Richmond, Heathcote Valley
- Coastal/erosion: South New Brighton, Southshore, Sumner, Redcliffs
- Liquefaction zones: Aranui, Wainoni, Avondale, Dallington, parts of Kaiapoi
- Multiple hazards: Eastern suburbs generally, riverside properties
How does land categorisation affect my insurance, even if my home wasn't damaged?
Every Christchurch property is now viewed through the lens of TC categories. Even if your property performed well in the earthquakes, being on TC2 or TC3 land means higher premiums. Insurers price for potential risk, not past performance. Your undamaged TC3 property still needs expensive foundations for any rebuild.
The massive earthquake claims pushed up everyone's premiums - insurers spread risk across all Canterbury properties. Additionally, the earthquakes revealed previously unmapped risks. Properties that seemed safe are now recognised as vulnerable, reflected in pricing even without a claims history.

My apartment body corporate says I'm covered - do I really need separate home insurance?
Yes - Body corporate insurance typically covers only the building structure and common areas; however, you will need to check this, as cover varies.
How much more does area replacement cost in Christchurch?
Area replacement premiums are typically 10-20% more than sum insured premiums nationwide, though this varies by property and insurer. If your sum insured policy costs $6,000 annually, expect to pay an extra $900 to $2,000+ per year.
However, the upside can be significant - if you're underinsured by 30% on an $800,000 rebuild, you will face a $240,000 shortfall. That's 320 years' worth of premium savings wiped out in one claim. For Christchurch properties where rebuild costs are volatile and disasters increasingly common, Area Replacement is cost-effective protection.

Our View: If you're buying a home in a known flood zone, make insurance a condition of purchase - get confirmed coverage before going unconditional.
- Try MAS and FMG
- Use an insurance broker who knows which insurers are still accepting risk
- Be prepared for high premiums and excesses
- Never let existing coverage lapse

What should Christchurch apartment owners know about the "body corporate insurance gap"?
The biggest insurance mistake Christchurch apartment owners make is assuming body corporate coverage is enough - it’s essential to read the policy purchased and understand it. We suggest considering getting your own contents insurance, and consider "improvements" coverage for any upgrades you've made.

- Approval process: 2-4 months
- Builder availability: 6-18 months wait
