# S-P08-C-03: I'm worried we could lose all our belongings in a flood. How do we work out how much contents cover we need? Collected 11 October 2026 [Home and contents insurance study](https://nzbrands.ai/research/insurance/home-contents-insurance) ## ChatGPT Answer ID: e1cfcbc3-5eb1-46ac-a8fb-561822f9b240 It's completely understandable to worry about this. Flooding can happen quickly, and the thought of losing everything in your home is frightening. The good news is that there are practical ways to work out how much contents insurance you need, so you're not left trying to replace your belongings out of your own pocket. **The key is to calculate what it would cost to replace everything you own if your home were flooded and your belongings were all destroyed.** Don't base the figure on what you paid for things years ago or what you think they're worth second-hand. Here's how I'd approach it in New Zealand. ## 1. Work out what you'd need to replace Imagine that you had to move into an empty home tomorrow and buy everything you currently own. Go through your home room by room and estimate what it would cost to replace each item. Use the cost of buying an equivalent new item where your policy provides replacement cover. | Room or category | What to include | |---|---| | Living room | Sofas, armchairs, television, entertainment system, rugs, lamps, curtains and decorations | | Kitchen | Fridge, freezer, microwave, kettle, toaster, pots, pans, crockery, cutlery and food | | Bedrooms | Beds, mattresses, bedside tables, wardrobes, dressers, bedding and clothing | | Bathroom | Towels, toiletries, hairdryers and other personal items | | Laundry | Washing machine, dryer, laundry equipment and cleaning supplies | | Home office | Computers, monitors, printers, desks, chairs and other electronics | | Garage and storage | Tools, gardening equipment, bicycles, sports gear and camping equipment | | Personal valuables | Jewellery, watches, handbags, artwork, musical instruments and collectibles | | Miscellaneous | Books, toys, children's belongings, ornaments, suitcases and seasonal decorations | **Don't overlook the small things.** Towels, shoes, underwear, kitchen utensils, cleaning products and children's toys can add up to thousands of dollars when you need to replace everything at once. Also include belongings belonging to other household members, where your policy covers them. Consumer NZ explains the importance of estimating the total replacement cost of your belongings rather than simply considering your most valuable possessions.

Use a contents insurance calculator You don't have to price every single item yourself. Several New Zealand insurers provide free online calculators that estimate how much it would cost to replace your household contents. Here are two places to start: - **[NZI Contents Sum Insured Calculator](https://www.nzi.co.nz/personal-cover/contents-insurance/contents-calculator)** — estimates the replacement value of your belongings based on information about your household. - **[ASB Contents Insurance Calculator](https://www.asb.co.nz/home-and-contents-insurance/contents-insurance-calculator.html)** — helps estimate the cost of replacing your household contents. These calculators can give you a useful starting figure in just a few minutes. However, they are estimates, so you should check whether they adequately account for your possessions, particularly if you have expensive furniture, electronics, jewellery or collections. [nzi.co.nz](https://www.nzi.co.nz/personal-cover/contents-insurance/contents-calculator?utm_source=chatgpt.com), [asb.co.nz](https://www.asb.co.nz/home-and-contents-insurance/contents-insurance-calculator.html?utm_source=chatgpt.com) **My recommendation:** Use one calculator first, then check the result against the actual belongings in your home. If the estimate seems surprisingly low, investigate before settling on that amount. ## 3. Remember that replacement costs can be much higher than you expect This is one of the biggest traps when choosing contents cover. You might think your belongings are worth $40,000 because you've accumulated them over many years. But if you had to buy everything again at today's prices, the total could be considerably higher. For example, imagine a household with the following replacement costs: | Category | Illustrative replacement cost | |---|---:| | Lounge furniture and television | $8,000 | | Beds, mattresses and bedroom furniture | $10,000 | | Clothing, shoes and personal belongings | $8,000 | | Kitchen appliances and equipment | $7,000 | | Computers, phones and electronics | $5,000 | | Garage tools, bicycles and outdoor equipment | $6,000 | | Curtains, linen, towels and household items | $4,000 | | Books, toys, decorations and miscellaneous items | $4,000 | | **Total** | **$52,000** | These figures are illustrative only, not a recommended insurance amount. Your actual total could be much lower or substantially higher. The important point is that **you need enough cover to replace everything at the same time**, rather than just enough to replace your biggest purchases. ## 4. Check that your policy actually covers flood damage Because flooding is your main concern, this step is especially important. Before choosing your sum insured, ask your insurer to confirm: - **Flood damage:** Does the policy cover household contents damaged by flooding from heavy rain, overflowing rivers or surface water? - **Stormwater and runoff:** Are there exclusions or special conditions for water entering your home from outside? - **Replacement cover:** Will the insurer replace eligible belongings with new equivalents, or pay their depreciated, second-hand value? - **Valuable items:** Are jewellery, watches, artwork, bicycles and electronics subject to individual limits? - **Temporary accommodation:** If flooding makes your home uninhabitable, will your policy help pay for somewhere else to stay? - **Removal and storage:** Is there cover for moving or storing your belongings if your home becomes unsafe? Policy wording matters because cover and limits vary between insurers. Consumer NZ notes that comprehensive contents policies commonly provide a combination of replacement-value cover and present-value cover, depending on the item and policy conditions. Temporary accommodation benefits may also apply following a natural disaster. [consumer.org.nz](https://www.consumer.org.nz/money/insurance/house-and-contents-insurance/guide?utm_source=chatgpt.com) One further point: New Zealand's Natural Hazards Commission (NHC Toka Tū Ake) does not cover household contents. You need to rely on your contents policy for those belongings, so make sure you understand its specific flood provisions. [consumer.org.nz](https://www.consumer.org.nz/money/insurance/house-and-contents-insurance/guide?utm_source=chatgpt.com) If you're particularly worried about flooding, ask your insurer to explain the cover for your circumstances in writing. ## 5. Make sure expensive items are covered separately if necessary Most contents policies have limits on certain categories of possessions. For example, you might own a $12,000 engagement ring, an expensive camera or a valuable collection. Even if your overall contents sum insured is high enough, a policy's limit for that particular category might not be. Check whether these items need to be individually listed on your policy, sometimes called *specified items*. Also check whether fitted carpets and curtains are covered by your contents or house insurance. The distinction can vary between policies.

Keep a record of what you own This is a simple step that can make a big difference if you ever need to make a claim. I'd suggest doing the following: - Take a video walking through every room, opening cupboards and showing what's inside. - Photograph expensive items individually. - Keep receipts or order confirmations for major purchases where available. - Save the photos, video and inventory somewhere outside your home, such as cloud storage. - Keep a copy of your insurance policy and policy schedule. You don't need to document every teaspoon. A video of your kitchen, for example, can help demonstrate how much equipment you owned before a flood. Consumer NZ also recommends taking photographs and videos when documenting damage for an insurance claim.

Review your cover regularly Once you've established a reasonable figure, check it at least annually and whenever you acquire significant new possessions. Your belongings and replacement costs change over time. A sum insured that was adequate three years ago might not be enough today. Remember, too, that the sum insured is generally the maximum amount available for a claim, subject to your policy's terms, limits and excess. You don't necessarily receive the entire sum insured just because you make a claim.

That will give us a starting point for estimating the replacement cost of your belongings and identifying the items people commonly forget. We can then refine the figure to suit your household, without you having to list every possession individually. ## Gemini Answer ID: 8927fc24-d341-499e-9d83-19e50b283929 It is completely understandable to feel anxious about protecting your home and belongings, especially with weather events becoming more unpredictable. Working out the right amount of contents insurance ensures you won't be left financially stretched trying to replace everything at once. Here is a practical, step-by-step guide to calculating your contents cover accurately: --- ### Step 1: Conduct a Room-by-Room Inventory The most accurate way to figure out your sum insured is to walk through your home and list everything it would cost to replace brand new. Don't forget to look in cupboards, drawers, the garage, and the shed. * **Living Areas:** Couches, TV, entertainment systems, rugs, lamps, books, and curtains. * **Kitchen:** Microwave, toaster, kettle, fridge/freezer, cookware, crockery, and cutlery. * **Bedrooms:** Beds, mattresses, linen, wardrobes full of clothes, shoes, and accessories. * **Garage & Outdoors:** Lawnmowers, tools, bicycles, outdoor furniture, and sports equipment. ### Step 2: Use an Online Calculator Most major New Zealand insurance providers (such as AMI, State, Tower, or AA Insurance) offer free **Contents Insurance Calculators** on their websites. You plug in the size of your household and general lifestyle, and it generates an estimated replacement value based on current market averages. This is a great baseline to check against your own inventory. ### Step 3: Account for Inflation and Replacement Costs When calculating, remember that insurance generally works on a **New for Old** basis (replacement value, not second-hand or trade-in value). * **Rising Costs:** The cost of furniture, electronics, and appliances has risen. Make sure you estimate what it costs to buy these items *today*, not what you paid for them five years ago. * **The "Under-insurance" Trap:** Many people accidentally under-insure by only counting major items. Make a list of your wardrobe—replacing every single piece of clothing and pair of shoes for a whole family can easily add up to tens of thousands of dollars. ### Step 4: Check for Special Limits on Valuables Most policies have **sub-limits** or single-item limits for high-value items. If you own expensive jewellery, fine art, high-end cameras, or designer watches, these may not be fully covered under a standard "general contents" limit. You may need to list them separately as specified items on your policy. --- ### Helpful Resources in New Zealand * **Insurance Council of New Zealand (ICNZ):** Offers great guidance on understanding sums insured and what standard policies cover. * **Your Provider's Calculator:** Visit your current insurer's website to use their specific sum insured calculator.

In New Zealand, most contents policies pay out up to a maximum set dollar limit called the **sum insured**. If you underestimate this amount, you will have to cover the financial shortfall yourself after a major flood. The most accurate way to find this number is to avoid guessing and use a structured estimation strategy. * * * 1\. Use an Online Contents Calculator Most New Zealand insurers use an independent database managed by **Sum Insured Pty Ltd**. This tool automatically estimates replacement values based on your house size, location, and family setup. You can access this calculator through major providers: * Use the AA Insurance Contents Calculator or Vero Home Contents Calculator to map out a room-by-room estimate. * Try the AMI Contents Calculator or State Insurance Inventory Tools to customize values based on the quality of your furnishings. 2\. Take a "Total Loss" Inventory When calculating for a flood, imagine your house was completely submerged and every single item had to be bought fresh from a store. Go room by room and include: * **The Big Items:** Furniture, beds, whiteware, TV, and computers. * **The Hidden Costs:** Clothing, shoes, bed linen, curtains, and even food in the freezer. * **The Small Details:** Cookware, pots, pans, toiletries, and books. These add up to thousands of dollars very quickly. 3\. Check for Item Sub-Limits Standard Kiwi policies have hidden caps on specific types of high-value items. If you own items that exceed these standard limits, you must **specify them individually** on your policy: * **Jewelry and watches** * **Bicycles and e-bikes** * **Cameras and laptops** * **Collections and fine art** Calculating your Contents Value | Tower Insurance NZContents Sum Insured - AMIContents Insurance | Get a Quick Quote & Buy Online | AMI NZContents Insurance Calculator NZ 2026 | Sum Insured for 4\. Add an Inflation and Clean-Up Buffer Always round your final estimate upward. Building in a **10% to 20% buffer** ensures you are protected against sudden retail price increases, missing items you forgot to count, and potential post-disaster inflation. * * * To help point you toward the right insurance adjustments, could you tell me: * Are you **renting or do you own** the home? * Roughly how many **bedrooms** do you have? * Do you own any highly valuable items like **e-bikes or high-end jewelry** that might need special listing? ## Google AI Mode Answer ID: cc21becc-1c38-4832-8239-3d0b095e1dad Working out the right amount of contents cover for a total loss—like a severe flood—means calculating what it would cost to replace every single item brand new today, rather than what you originally paid or what the items are worth second-hand. Guessing a round number often leads to being underinsured, so a systematic room-by-room approach is safest. * **Room-by-Room Inventory** : Walk through your home space by space and estimate the current replacement cost of everything. * Living areas: sofas, TVs, electronics, rugs, curtains, books, and artwork. * Kitchen: appliances, cookware, crockery, cutlery, and pantry food. * Bedrooms & Wardrobes: beds, linen, and every item of clothing and shoes (wardrobes add up fast). * Bathrooms & Laundry: towels, portable appliances, and cleaning gear. * Garage, Shed & Outdoors: tools, lawnmowers, bikes, BBQs, and sports/camping gear (routinely undercounted). [Smiths Insurance and KiwiSaver] * **Check Special Limits** : Look at high-value items like jewellery, artwork, or high-end tech. Insurers often place single-item sub-limits or maximum payouts on these categories, so you may need to "specify" certain valuables individually on your policy. * **Include GST and Buffers** : Ensure your final total includes Goods and Services Tax (GST), and add a safety buffer of 10% to 15% to account for overlooked drawers, utility items, and inflation in replacement costs. [nzcalculator.co.nz] * **Use Insurer Tools** : You can cross-check your manual tally by using online calculators provided by major New Zealand providers, such as the NZI Contents Calculator or guidance from Consumer NZ. How to get the best house and contents insurance - guideContents Sum Insured Calculator - NZI If you'd like, let me know: * **The approximate size** of your home (number of bedrooms) * Do you have any **high-value specialty items** (like fine jewellery, extensive tool collections, or high-end art)?
