Yes. In New Zealand, there are several ways to shop around for home insurance when your house is near a river, without concealing the flood risk or giving up important protection.

The key is to get insurers to assess the same accurate information about your property, then compare not just the premium but also what each policy would actually cover if the river flooded.

## 1. Try these ways to find better quotes

- Use an independent insurance broker. A broker can approach multiple insurers, explain the property's flood exposure and look for insurers willing to consider it. Ask whether they can access specialist or non-standard underwriting options, not just standard online quotes.
- Approach insurers directly as well. Different insurers can assess flood exposure differently, so a refusal or high premium from one company doesn't necessarily mean every insurer will offer the same terms.
- Ask for alternative policy structures. For example, ask whether the insurer can offer a higher excess for flood damage, a different excess specifically for flooding, or cover with clearly defined flood-related exclusions. Compare the financial risk before accepting a cheaper policy.
- Ask your current insurer for a review. If the premium has increased, ask what is driving the price and whether updated property information, risk-mitigation measures or a different excess would change the quote.
- Compare home and contents insurance separately. A cheaper combined package isn't necessarily better if the contents policy has restrictive flood exclusions or limits.

## 2. Make your property easier for insurers to assess

Prepare a small information pack before requesting quotes. This can help insurers distinguish between a house that is genuinely exposed to flooding and one that is near a river but has a lower level of risk.

Include, where available:

- Flood history: whether the house or land has flooded, when it happened and the depth of any water.
- Council flood information: flood hazard maps, floor-level information and any available property-specific assessments.
- House details: floor height, construction, drainage and whether living areas or essential equipment are elevated.
- Risk-reduction work: drainage improvements, flood barriers or other measures already installed.
- Previous insurance history: claims, declined applications and any special terms imposed by earlier insurers.

Be factual about what you know, and don't describe an unverified property as flood-free. The Insurance Council of New Zealand specifically identifies flood exposure as a risk that may need to be disclosed.

## 3. Compare the cover, not just the premium

| What to check | Why it matters |
| --- | --- |
| Flood damage to the house | Is river flooding covered, limited or excluded? |
| Contents cover | Are furniture, appliances and belongings covered after a flood? |
| Flood excess | How much would you pay yourself for a claim? |
| Gradual water ingress | Is damage from rising groundwater or ongoing seepage excluded? |
| Rebuilding costs | Would the sum insured cover rebuilding the house? |
| Land and retaining structures | What damage is covered, and what is excluded? |

Pay particular attention to exclusions that use terms such as flooding, surface water, stormwater, overflow and groundwater. The wording can matter more than the insurer's general description of the policy.

Also, don't assume that Natural Hazards Commission (NHC) cover will pay for all river-flood damage to your house. Ask your insurer to explain which parts of a flood loss are covered by your home policy and which, if any, fall under NHC cover.

## 4. What to say when requesting quotes

You can use this message with a broker or insurer:

Subject
:   Home insurance quote request – property near a river

Hello,

I'm looking for competitive home and contents insurance for my property, which is located near a river.

I want to be transparent about the property's flood exposure and ensure that any quote accurately reflects the risks. I'm interested in comparing insurers, premiums, excesses and the actual extent of flood cover available.

Could you please advise:

- Whether you can obtain quotes from multiple insurers, including any that consider properties with flood exposure.
- What property information or flood assessments you need from me.
- Whether river flooding is covered, subject to an excess, or excluded under the available policies.
- Whether any risk-reduction measures or additional property information could affect the premium or terms.

I'd appreciate options that balance affordability with meaningful protection against flood damage.

Kind regards

## Let’s narrow down the best approach for your house

One detail would help me make the next steps more specific: has the house itself ever flooded, or is it near a river that creates a mapped or potential flood risk?

That distinction can help guide which documentation to gather, what questions to ask insurers and how to approach a broker.

Yes, you can look for alternative quotes without hiding your flood risk, and doing so is critical. In New Zealand, insurance contracts are governed by the principle of utmost good faith, meaning you have a legal duty to disclose all "material information" (anything that would influence an insurer's decision to accept the risk or set the price). Hiding a flood risk can lead to a policy being voided or a future claim being declined entirely.

Fortunately, many New Zealand insurers and digital platforms price risk dynamically using address-level data and council flood maps. This means you don't need to manually explain the geography—the system often already knows. 

Ways to shop around transparently and manage costs include:

*   **Use Address-Lookup Insurers:** Many online-first providers (such as Initio or various broker networks) automatically pull council hazard and flood-zone layers when you type in your address. This gives you an upfront, transparent quote reflecting the actual risk without risking non-disclosure.
*   **Engage an Insurance Broker:** A broker (especially one part of a network like Rothbury or Abbott) acts as your advocate. They know which underwriters have a higher risk appetite for flood-prone properties and can negotiate or source specialist policies that standard comparison sites might reject or price out automatically.
*   **Opt for a Higher Flood Excess:** If premiums are high because of the river proximity, ask insurers if they offer a **flood-specific excess** (e.g., agreeing to pay the first $2,500 or $5,000 of a flood-related claim yourself). Accepting a higher, compartmentalized excess often lowers the overall annual premium significantly.
*   **Check for Community Mitigation Works:** If your local council has built or planned stopbanks, drainage upgrades, or flood-mitigation infrastructure near your property, let prospective insurers know. Insurers increasingly factor completed community-level protections into their pricing.
*   **Mitigate Property-Level Risk:** If you have made any physical modifications to protect the house (such as raising electrical outlets, improving localized drainage, or installing flood barriers), highlight these features to underwriters as risk-reduction steps.

Yes, there are honest, transparent ways to look for alternative home insurance quotes. In New Zealand, insurance companies have shifted firmly from "community rating" to **address-level, risk-based pricing**. This means automated systems already pull data directly from council GIS hazard maps, NIWA models, and historical flood files the moment you input your specific address.

You do not need to hide anything; instead, you can actively shop around, test the market, and leverage tools to ensure you are getting the fairest rate.

1\. Use Independent Insurance Brokers

 * **The Approach:** Instead of using automated online quote engines, engage a registered **NZ insurance broker**.

 * **Why it works:** Brokers have direct access to specialized underwriters and can manually advocate for your case. They can present any private mitigation work you’ve done (e.g., retaining walls, raised floor levels) that standard corporate algorithms ignore.

 * **Action:** Look for brokers registered with bodies like the **Financial Services Complaints Ltd (FSCL)** or **Insurance & Financial Services Ombudsman Scheme (IFSO)**.

2\. Test the Major NZ Underwriting Groups Directly

The NZ home insurance market is heavily consolidated, but pricing algorithms differ between the major groups. You should gather quotes across the distinct underwriting backbones:

 * **IAG Group:** Brands include **AMI** , **State** , and **NZI** (via brokers).

 * **Suncorp Group:** Brands include **Vero** (via brokers) and **AA Insurance**.

 * **Tower Insurance:** Operates independently and relies heavily on its own advanced, granular digital risk-mapping technology.

3\. Strategic levers to lower your premiums legally

If you are struggling with high quotes due to the river proximity, use these adjustments with prospective insurers to lower the premium cost:

Strategy| Action| Impact on Premium
---|---|---
**Increase Voluntary Excess**| Raise your standard excess (e.g., from $500 to $2,000 or $5,000).| **High reduction**. You take on more minor risk, which lowers your ongoing premium.
**Audit Sum Insured**| Use the Cordell Calculator to accurately recalculate your exact house rebuild cost. Do not include land value.| **Medium reduction**. Prevents over-insuring your asset.
**Inquire About Higher Special Excess**| Ask if the provider offers a specific, higher excess strictly for flood events while keeping standard excess low for fires/theft.| **Variable**. Can make an otherwise "uninsurable" or high-premium home affordable.

⚠️ A Note on the NZ Market Reality

Be aware that the cost of home insurance across New Zealand has risen **916% since 2000** , heavily driven by climate risks and reinsurance costs. If you find a competitive quote, ensure it includes full flood cover and isn't excluding natural disasters. According to Consumer NZ, more Kiwi households are being squeezed out of affordability. If an alternative company offers you cover, secure it before canceling your current policy.

To help narrow down your options, what **company** are you currently insured with, and have you checked your council's **flood mapping tools** to see exactly how your property is classified?

Yes, you can absolutely shop around and compare quotes transparently. In _New Zealand_ , private insurers don't rely solely on what you verbally declare about natural hazards; they use sophisticated, automated geographic information systems (GIS) and mapping data provided by councils, NIWA, and the [Natural Hazards Commission Toka Tū Ake](https://www.naturalhazards.govt.nz/insurance-and-claims/cover-for-storm-flood-and-landslide-damage/) to assess flood risk the moment you enter your address.

Hiding or failing to disclose known material risks can breach your duty of utmost good faith or disclosure requirements under New Zealand insurance contract law, potentially invalidating a claim later.

Strategies to look for better quotes transparently include the following:

 * * Use online comparison and direct quoting: Go directly to multiple insurer websites (such as [Tower Insurance NZ](https://www.tower.co.nz/house-insurance/) or [AMP NZ](https://www.amp.co.nz/my-insurance/home-insurance)) or independent broker networks. Because they pull property-specific hazard maps using your physical address, the flood risk is priced in automatically from the start without you needing to manually unpack or guess how to frame it.

 * Adjust your excess: Raising your voluntary excess (the amount you pay out-of-pocket before insurance kicks in) can substantially lower your annual or monthly premium. Just ensure it is set to an amount you could comfortably afford if a non-flood claim occurred.

 * Review your sum insured vs. area replacement: Understand whether your policy calculates payouts via a fixed maximum sum insured or a broader area-replacement/total-rebuild model, and adjust your coverage parameters accurately to avoid paying for over-insurance.

 * Mitigate and document property risk: If you have implemented any flood-mitigation measures (such as improved local drainage, retaining structures, or raising electrical components), explicitly mention these to insurers or brokers. Documented mitigation can sometimes offset the high-risk penalty applied to a riverside location.

 * Speak to an insurance broker: An independent broker has access to multiple mainstream and niche insurers (including wholesale or specialist markets) and can advocate for your property by presenting its true risk profile alongside any protective factors you've established.

 *

If you'd like, let me know:

 * Have you already checked **specialist brokers** or only major direct insurers?
 * What kind of **mitigation steps** (if any) have been done on the property?

I can help suggest next steps for **optimising your coverage and premium**.
