Contents Insurance Sum Insured NZ (2026): How to Value What You Own Without Guessing

How to set the right contents insurance sum insured in NZ for 2026: a room-by-room valuing method, the special-limits trap on valuables, new-for-old vs indemnity, and why guessing leads to underinsurance.

Contents insurance asks you to put a single number on everything you own — and most people guess low. That guess is the figure your insurer uses to settle a claim, so getting it close to reality matters more than the policy logo on the front. This article sets out a room-by-room way to value your contents, the special limits that catch people out on valuables, and how new-for-old and indemnity cover differ.

It is general information, not advice about your situation, but it should help you sense-check your own sum insured before you ever need to claim.

How is contents insurance different from house insurance in NZ?

TL;DR: House insurance covers the building; contents insurance covers the things inside it that you'd take with you if you moved. You set a contents sum insured — a dollar figure for replacing it all. Most New Zealanders under-value contents by roughly 30% to 50% ², and unlike buildings, contents are no longer covered by the government natural-hazard scheme ⁷, so getting the number right sits with you.

House insurance and contents insurance answer two different questions. House cover deals with the structure — walls, roof, fixed kitchen, built-in wardrobes — and is usually set on a rebuild cost. Contents cover deals with the moveable items: furniture, appliances, clothing, electronics, tools, sports gear, and the contents of the garage and shed.

A useful test is the "tip it upside down" one. If you turned your home upside down, everything that fell out is broadly contents; everything that stayed fixed is broadly the building. Carpets, curtains and light fittings can sit in either column depending on the policy, which is one reason reading the wording matters.

Contents insurance is not only a homeowner concern. Around one-third of New Zealand tenants do not hold contents insurance, compared with about 92% of homeowners who do ¹ — yet a renter's furniture, clothing and electronics can cost just as much to replace as an owner's. The building is the landlord's problem; the contents are the tenant's.

How do you actually value your contents room by room?

Guessing a round number for the whole house is where under-valuing starts. A more reliable method is to value one room at a time and add the rooms together. It is slower, but it catches the things a single guess misses.

Work through each space and note the replacement cost of what's in it — what it would cost to buy the item new today, not what you paid or what it's now worth second-hand:

• Living areas: sofas, TVs, sound systems, rugs, curtains, bookshelves and books, artwork, lamps.
• Kitchen: small appliances, cookware, crockery, glassware, cutlery, pantry contents.
• Bedrooms: beds and mattresses, wardrobes of clothing and shoes, linen, drawers of accessories.
• Bathrooms and laundry: towels, the washing machine and dryer if not built in, cleaning gear.
• Home office: computers, monitors, printers, desks, chairs.
• Garage, shed and outdoors: tools, the lawnmower, bikes, BBQ, camping and sports equipment, outdoor furniture.

Two areas are routinely undercounted: clothing (a full wardrobe replaced new adds up fast) and the garage and shed (tools and outdoor gear quietly total thousands). Most major insurers — Vero, AMI, State, AA and NZI among them — offer an online contents calculator that walks you through rooms and totals a suggested figure ². Using one as a cross-check against your own room-by-room tally is sensible; if the two numbers are far apart, it's worth understanding why before you settle on a figure.

The reason the room-by-room method matters is in the data. Estimates drawn from NZ contents calculator methodology put under-valuation at roughly 30% to 50% ². On a home that would genuinely cost $90,000 to refurnish, a 40% gap means insuring for around $54,000 — and carrying the rest yourself.

What are 'special limits' and why do they catch people out?

Your sum insured is the overall ceiling, but it is not the only limit in the policy. Most contents wordings apply special limits — smaller per-item and per-event caps on particular categories such as jewellery, watches, cameras, bicycles, money and artwork — unless those items are specified (listed individually) on the policy.

This is the trap. You can hold a $100,000 sum insured and still find a single ring is only covered to a few thousand dollars, because the jewellery sub-limit applies regardless of how much total cover you hold. The limits vary widely between insurers, which is why like-for-like comparison matters. The figures below are examples from current published wordings, not a recommendation of any one insurer, and they are not the whole market — always check the specific policy wording.

The point of the table is the spread. One insurer caps unspecified jewellery at $3,000 per item; another at $8,000. If you own an engagement ring, a good camera, an e-bike or a watch worth more than the relevant sub-limit, the usual fix is to specify the item — list it by description and value, sometimes with a valuation — so it's covered for its full amount rather than the default cap. Specifying often costs a little extra premium, but it closes a gap that a high overall sum insured does not.

Should you insure for new-for-old or indemnity value?

Contents policies settle on one of two bases, and the difference is large at claim time.

Replacement (new-for-old) cover replaces a lost or damaged item with a new equivalent, subject to age limits and your sum insured ⁶. Your ten-year-old TV is replaced with a current model rather than its depreciated value.

Indemnity (present value) cover pays the depreciated value of the item at the time of loss ⁶ — what the used item was actually worth, accounting for age and wear. The same ten-year-old TV is settled at its second-hand value, which may be a fraction of a replacement.

New-for-old is the more common choice for standard household contents because it avoids depreciation, but it carries a higher premium and may still apply age limits to certain items. Indemnity cover is cheaper but pays less, particularly on older possessions. Which suits a given household depends on the mix and age of what they own and their budget — there is no single right answer, and the policy wording sets out exactly how each basis applies.

How do unspecified vs specified valuables work?

This follows directly from special limits. Unspecified items are covered under the general contents sum insured but only up to the relevant special limit — for example, jewellery to $3,000 per item under one common wording ⁴. You don't list them individually; the trade-off is the cap.

Specified (or scheduled) items are listed individually on the policy with a description and value, and are covered for that amount rather than the default sub-limit. Specifying is the usual route for higher-value possessions:

• Engagement and wedding rings, and other valuable jewellery.
• Expensive watches.
• Cameras and lenses.
• High-end bicycles and e-bikes.
• Artwork, collections and antiques.

Specifying typically adds a small premium and may require a recent valuation or receipt, and it can extend cover beyond the home (for items worn or carried away) depending on the wording. The decision is a straightforward weigh-up: the extra premium against the size of the gap the default sub-limit would otherwise leave.

How does underinsurance affect a contents claim?

Underinsurance is the practical cost of guessing low. If your sum insured is below the true replacement cost of your contents, you carry the shortfall — and the gap shows up most painfully in a total loss, such as a house fire, where the claim is capped at your sum insured no matter what the contents were really worth.

This is why the under-valuation finding matters so much. With Kiwis estimated to under-value contents by 30% to 50% ², a household that should insure for $80,000 but nominates $50,000 is exposed by $30,000 if everything is lost. The insurer pays up to the nominated figure; the rest falls on the household.

A second pressure is cost. The average New Zealand contents premium was around $863 a year (about $72 a month) in late 2025, up on earlier years amid claims inflation ⁸. Rising premiums tempt people to trim cover by lowering the sum insured — which quietly widens the underinsurance gap at the very moment replacement costs are also climbing. Cutting the number to cut the premium is the most common way households drift into being underinsured.

It's also worth knowing what your policy no longer falls back on. Residential contents are not covered by New Zealand's government natural-hazard scheme: the former $20,000 EQC contents cover was phased out over 12 months from 1 July 2019, and under the Natural Hazards Insurance Act 2023, contents must be fully insured privately ⁷. (The scheme's building cap is generally $300,000 plus GST per dwelling per event ⁷, but that is buildings, not your belongings.) After an earthquake, your contents claim rests entirely on your private contents policy and the sum insured you set — there is no public backstop. The same principle for buildings is covered in [our guide to house insurance](blog-post-house-insurance).

Figure: Typical contents value by household type

Source: ICNZ guidance and insurer contents calculators; illustrative of where each household type typically under-insures ¹². Values vary by household — use a room-by-room tally or insurer calculator for your own figure.

The takeaway from the figure is that the gap shows up differently for each household: renters by going uninsured, families by under-valuing the whole, and downsizers by leaving valuables unspecified. None of these is fixed by a bigger round number — they're fixed by valuing properly and specifying where needed.

How often should you update your contents sum insured?

Contents change more than buildings do. New appliances, a replaced TV, a new bike, a growing wardrobe, gifts and inherited items all push the real figure up over time, while an unchanged sum insured slowly falls behind.

A reasonable rhythm is to review the figure once a year, usually at renewal, and again after any significant purchase or change — a house move, a major appliance upgrade, a new e-bike, or receiving valuable jewellery. At each review, two checks do most of the work: is the overall sum insured still close to the room-by-room replacement total, and are any newly valuable items above the special limits and worth specifying.

One date-sensitive cost to be aware of in 2026: the Fire and Emergency NZ (FENZ) levy on a contents policy. The maximum FENZ levy on contents was $23.90 as at early 2026, scheduled to drop to $21.48 from 1 July 2026 ⁹ — a small figure, but one that changes mid-year.

Frequently asked questions

How much contents insurance do I need in NZ? Enough to replace everything you own at today's prices. The most reliable way to find the figure is a room-by-room tally of replacement costs, cross-checked against an insurer's contents calculator. Most New Zealanders under-value contents by roughly 30% to 50% ², so a quick round-number guess usually falls short.

Are my valuables fully covered under my contents sum insured? Not automatically. Most policies apply special limits — for example, unspecified jewellery capped at $3,000 per item under one common wording ⁴, or $8,000 under another ⁵ — regardless of your total sum insured. Items worth more than the relevant sub-limit usually need to be specified individually to be covered in full ³⁴⁵.

What's the difference between new-for-old and indemnity contents cover? New-for-old (replacement) cover replaces a lost item with a new equivalent, subject to age limits and your sum insured. Indemnity cover pays the depreciated, present-day value of the used item instead ⁶. New-for-old usually costs more but pays more, especially on older possessions.

Does renters' insurance cover my contents? Renters' (contents) insurance covers a tenant's own belongings; the landlord's policy covers the building, not your things. Around a third of NZ tenants hold no contents cover ¹, leaving furniture, clothing and electronics uninsured. The sum-insured and special-limit rules work the same way as for homeowners.

Are my contents covered for earthquake damage? Only through your private contents policy. The former $20,000 EQC contents cover was removed, phased out from 1 July 2019, so under the Natural Hazards Insurance Act 2023 contents must be fully insured privately ⁷. There is no public scheme behind your belongings — the sum insured you set is the limit.

How often should I review my contents sum insured? Around once a year at renewal, and again after any major purchase, a house move, or receiving valuable items. Check that the overall figure still matches a room-by-room replacement total, and that newly valuable items above the special limits are specified ²³.
