Insurance paperwork can feel like it is written in another language. This plain-English glossary breaks down 40+ common insurance terms used in New Zealand - so you can read your policy with confidence and know exactly what you are signing up for.
Insurance documents are packed with technical terms that can make even straightforward policies feel overwhelming. But understanding what these words mean is not just an academic exercise - it directly affects your cover, your costs, and what happens when you need to make a claim.
According to Citizens Advice Bureau (CAB), one of the most common reasons people run into trouble with insurance is that they did not fully understand the terms and conditions of their policy. The Insurance and Financial Services Ombudsman (IFSO) also reports that misunderstandings around policy wording are a frequent source of disputes.
This glossary is designed to help. We have grouped the most common NZ insurance terms into categories so you can quickly find what you need - whether you are buying a new policy, reading a renewal notice, or working through a claim. For a broader overview of how insurance works, see our guide to how insurance works in NZ.
These are the foundational terms you will encounter on almost every insurance policy in New Zealand. Understanding these gives you a solid base for reading any insurance document - whether it is for your car, home, health, or anything else.
Every policy has a set structure: who is covered (the insured), what is covered (the scope), what is not covered (the exclusions), and under what conditions. The terms below are the building blocks of that structure.
| Term | What It Means in Plain English |
|---|---|
| Policy | Your insurance contract. It is a legal agreement between you and the insurer that sets out what is covered, what is excluded, and the conditions that apply. |
| Policy Wording | The detailed document (sometimes called the Product Disclosure Statement or PDS) that spells out exactly what your insurance covers and does not cover. Always worth reading - not just the summary. |
| Policyholder / Insured | The person (or business) who holds the insurance policy. This is usually the person who took out the policy and is named on it. |
| Insurer / Underwriter | The company that provides the insurance cover and agrees to pay valid claims. In NZ, insurers must be licensed by the Reserve Bank of New Zealand. |
| Period of Insurance | The dates your policy runs from and to. Cover only applies during this period. Most policies in NZ run for 12 months and then come up for renewal. |
| Endorsement | An official change or addition to your policy. For example, if you add a named driver to your car insurance, that change is documented as an endorsement. |
| Certificate of Insurance | A summary document confirming that you have insurance. It typically lists the key details - who is insured, what is covered, the policy number, and the dates of cover. |
| Renewal | When your policy period ends, the insurer offers to continue your cover for another term - usually another 12 months. Your premium may change at renewal. |
When something goes wrong and you need to use your insurance, the claims process kicks in. The terms in this section cover what happens between the event and the payout - and the language used to describe what your policy will and will not pay for.
For a step-by-step walkthrough of the claims process, see our guide to making an insurance claim.
| Term | What It Means in Plain English |
|---|---|
| Claim | A formal request to your insurer asking them to pay for a loss or event that your policy covers. You normally need to provide evidence of the loss (photos, receipts, a police report, etc). |
| Exclusion | Something your policy specifically does not cover. Exclusions are listed in the policy wording. Common exclusions include wear and tear, intentional damage, and certain natural disasters depending on the policy. |
| Indemnity | The principle that insurance aims to put you back in the same financial position you were in before the loss - no better and no worse. You are not meant to profit from an insurance claim. |
| Benefit | The amount or service the insurer provides when you make a valid claim. For health insurance, this might be a cash payment towards surgery. For car insurance, it might be covering repair costs. |
| Liability | Legal responsibility. Liability insurance covers costs if you are found legally responsible for injuring someone or damaging their property. Third-party car insurance is a common example. |
| Third Party | Someone other than you and the insurer. In car insurance, third-party cover pays for damage you cause to other people or their property - but not for damage to your own vehicle. |
| Subrogation | After your insurer pays your claim, they may have the right to recover the cost from whoever caused the loss. For example, if another driver caused a crash, your insurer may pursue that driver or their insurer for reimbursement. |
| Total Loss / Write-Off | When the cost of repairing something (usually a vehicle) exceeds its value, so the insurer declares it a total loss and pays out the insured value instead of repairing it. |
How your insurer values what is being covered matters a lot - especially at claim time. The difference between agreed value, market value, and sum insured can mean thousands of dollars in a payout. These terms crop up most often in car insurance and house insurance.
Our guide to agreed value vs market value goes into much more detail on this topic. The Insurance Council of New Zealand (ICNZ) also has helpful consumer information on how valuations work.
| Term | What It Means in Plain English |
|---|---|
| Agreed Value | You and the insurer agree on a set value for the insured item when you take out the policy. If it is a total loss, the insurer pays that agreed amount. Common with car insurance. See our agreed value guide. |
| Market Value | The insurer pays what the item was worth on the open market at the time of the loss - not what you paid for it or what it would cost new. Market value can be lower than you expect, especially for older vehicles. |
| Sum Insured | The maximum amount the insurer will pay out under your policy. For house insurance, this is the total amount available to rebuild your home. It is important to set this figure accurately to avoid being underinsured. |
| Replacement Value / New for Old | The insurer pays the cost of replacing the lost or damaged item with a brand-new equivalent, rather than paying what the old item was worth. Common with contents insurance policies. |
| Underinsurance | When the sum insured or cover amount on your policy is not enough to fully cover the actual cost of a loss. For example, if your house would cost $600,000 to rebuild but you only have $450,000 in cover. The Sorted.org.nz underinsurance guide has useful tips on avoiding this. |
| Specified Item | A specific high-value item listed separately on your policy (e.g. an engagement ring or laptop). Specifying items ensures they are covered for their full value, including outside the home. |
Health and life insurance come with their own set of jargon. Many of these terms relate to your medical history, what conditions are covered, and how long you need to wait before certain benefits kick in. The Financial Markets Authority (FMA) has further guidance on understanding insurance products in NZ.
If you are weighing up whether health cover is right for your situation, our guide on health insurance in NZ covers the key considerations.
| Term | What It Means in Plain English |
|---|---|
| Pre-existing Condition | A health condition or injury you already had (or had symptoms of) before you took out the policy. Most health and life insurance policies exclude or limit cover for pre-existing conditions. |
| Waiting Period / Stand-Down Period | A set period of time after your policy starts during which you cannot claim for certain conditions or treatments. Common in health insurance - for example, a 3-month stand-down for non-urgent surgery. |
| Underwriting | The process an insurer uses to assess your risk before offering you a policy. For health and life insurance, this often involves reviewing your medical history, age, occupation, and lifestyle. The insurer decides whether to offer you cover and on what terms. |
| Medical Underwriting | A deeper level of underwriting where the insurer reviews your specific health details - sometimes requiring a medical exam, GP notes, or blood tests - before deciding whether to cover you. |
| Guaranteed Renewal | A policy term meaning the insurer cannot cancel your policy at renewal time as long as you continue paying your premiums. They can still change the premium, but they cannot refuse to renew. |
| Benefit Limit | The maximum amount your health insurer will pay for a particular treatment or in a given year. For example, a $50,000 annual limit on surgical benefits means the insurer will not pay more than that in one year. |
| Trauma / Critical Illness Cover | A type of life or health insurance that pays a lump sum if you are diagnosed with a specified serious illness, such as cancer, heart attack, or stroke. The payout is a fixed amount regardless of actual medical costs. |
These terms relate to your legal obligations as a policyholder, the regulatory framework around insurance in New Zealand, and what happens if things go wrong. New Zealand has strong consumer protections for insurance, overseen by bodies like the FMA, the Reserve Bank, and the IFSO scheme.
If you ever feel you have been treated unfairly by an insurer, our guide to complaining about an insurer walks through your options step by step.
| Term | What It Means in Plain English |
|---|---|
| Duty of Disclosure | Your legal obligation to tell the insurer everything that is relevant to the risk they are covering - honestly and completely. Under NZ law, failing to disclose important information can void your policy entirely. |
| Utmost Good Faith | A legal principle (also known as uberrimae fidei) that means both you and the insurer must deal with each other honestly and fairly. Neither side should withhold important information. |
| Material Fact | Any piece of information that could influence the insurer's decision to offer you cover or set your premium. For example, a previous claim, a medical condition, or security features on your car. |
| IFSO (Insurance and Financial Services Ombudsman) | A free, independent dispute resolution service in NZ. If you cannot resolve a complaint directly with your insurer, you can take it to the IFSO scheme at no cost. |
| FMA (Financial Markets Authority) | The NZ government agency that regulates financial markets, including insurance. The FMA sets conduct standards for insurers and protects consumers. |
| EQC (Earthquake Commission / Toka Tu Ake) | A NZ government body that provides natural disaster insurance for residential property. EQC cover is automatically included when you buy home or contents insurance. Learn more in our EQC guide. |
| Void / Avoidance | When an insurer cancels your policy from the start - as if it never existed - usually because of non-disclosure or misrepresentation. A voided policy means no claims will be paid. |
| Statute of Limitations | The time limit within which legal action must be taken. In NZ, the general limitation period for insurance disputes is six years from the date of the event. |
Knowing the jargon is half the battle. The other half is knowing where to look and what to pay attention to when you sit down with an actual policy document. Here are some practical pointers for getting the most out of your policy wording.
