How life insurance underwriting works

An insurer is agreeing to pay a large sum of money on the happening of an event it cannot control. Underwriting is how it works out how likely that event is for you specifically, and prices accordingly. It is not a moral judgement and it is not a health check. It is a pricing exercise performed on incomplete information, under time pressure, by someone who has never met you.

The consequence is that underwriting rewards evidence. An underwriter who can see a specialist letter saying a condition is stable and reviewed annually can offer standard rates. One who sees a tick-box answer and a gap in the records has to price for the worst version of what that gap might contain.

Underwriting is also front-loaded. Once the policy is issued, the insurer cannot re-underwrite you because your health changed — that is the whole point of the contract. What it can do is examine the application again at claim time. Getting the disclosure right at the start is what makes the policy work later.

The sequence is fairly consistent across New Zealand insurers, even though the software and the turnaround times are not.

1. 1

   Application and health statement

   A structured set of questions — personal details, occupation, income, existing cover, smoking status, build, pastimes, travel, family history and a long medical section. Most insurers now run this as a reflexive online interview, where a yes opens follow-up questions specific to that condition.

2. 2

   Automated assessment

   Straightforward applications are decided by rules engines within minutes. If every answer is clean, the system can issue standard terms without a human ever looking at it.

3. 3

   Referral to an underwriter

   Anything the rules cannot resolve goes to a person. That is where judgement enters, and where the quality of the supporting information starts to matter.

4. 4

   Evidence gathering

   The underwriter may request a condition-specific questionnaire, a report from your GP, a specialist letter, recent test results, a nurse visit, or a financial questionnaire on larger sums insured.

5. 5

   The offer

   The insurer sets out terms in writing: the premium, and any loading, exclusion or special condition attached. You are not obliged to accept, and an adviser will often go back and argue the point or take the same evidence to a different insurer.

6. 6

   Acceptance and issue

   You accept the terms, the first premium is arranged, and the insurer issues the policy. Cover starts on the date the policy schedule says it starts — not on the day you applied.

Timeframes range from minutes to a couple of months. An application involving GP notes, a specialist report and a nurse visit commonly takes four to eight weeks, most of which is spent waiting for a medical practice to send records.

Six categories of information do most of the work. The weighting differs by product — income protection underwriting is far more interested in your occupation and your musculoskeletal and mental health history than life cover underwriting is.

Age and sum insured

These two set the size of the risk and therefore how much evidence the insurer will buy. Every insurer runs a medical evidence grid: below certain age and sum-insured thresholds, nothing is required beyond your answers. Above them, bloods, a nurse visit or a full medical are triggered automatically regardless of how healthy you are.

Personal medical history

What you have been diagnosed with, investigated for, treated for or referred about. Underwriters care about how recent it was, how well documented the current position is, and whether there is any sign it is progressing. Symptoms you have not yet had investigated are also disclosable.

Family history

Usually limited to immediate family — parents and siblings — and to conditions with a known heritable component appearing before a specified age. A parent diagnosed with heart disease at 45 matters. A grandparent diagnosed at 80 generally does not.

Build, smoking and alcohol

Height and weight, nicotine and vaping use within the insurer’s stated period, and typical weekly alcohol intake. These are not moral questions; they are actuarial inputs with established loadings attached.

Occupation, pastimes and travel

Occupation drives income protection and TPD terms more than anything else, through the occupation class system. Pastimes — motorcycling, diving, aviation, climbing, contact sport — usually affect cover through an exclusion or a per-activity loading rather than a decline. Extended travel or residence in certain countries can produce a deferral until you are back.

Financial justification

For larger sums insured the insurer asks why you need that much. Income, assets, debts and the purpose of the cover are checked against multiples it is willing to write. This is separate from the medical assessment — you can be medically standard and still be offered less cover than you asked for.

Every application ends in one of five places. Four of them are still cover.

Loadings and exclusions are not interchangeable. A loading costs money but the cover is complete. An exclusion costs nothing but carves a hole in the policy exactly where your history suggests a claim is most likely. Where an insurer offers you the choice, take advice rather than defaulting to the cheaper one.

A deferral is not a rejection. It means the insurer cannot price the risk while something is unresolved — a pending test result, a recent change of medication, a recent operation — and would rather look again when it can. Most deferrals convert to an offer when you reapply.

A decline is serious mainly because of what it does to future applications. Every insurer asks whether you have ever been declined, loaded or had special terms applied, and you must answer honestly. That is why the order of operations matters so much, and why anyone with a complicated history should be pre-assessed before a formal application is ever submitted.

People assume underwriting is standardised. It is not. There is no shared New Zealand rule book. Each insurer sets its own underwriting manual, and behind that manual sits a reinsurance treaty — an agreement with a global reinsurer that carries part of the risk and, in practice, sets the limits of what the insurer can accept without referring the case upward.

Those treaties get renegotiated. Reinsurers change their view on a condition as new claims data arrives, and an insurer’s appetite can shift within a quarter with no public announcement. A condition routinely loaded last year may be standard this year at one insurer and excluded at another.

• One insurer may load a well-controlled condition where another accepts it at standard rates.
• One may exclude a body system entirely where another excludes only the specific joint or diagnosis.
• Mental health appetite in particular varies enormously and moves faster than most other categories.
• Some insurers underwrite a condition well on life cover but very conservatively on income protection.
• Maximum sums insured available with a loading differ, so a large case can be placeable at one insurer only.

This is the strongest argument for using an adviser rather than applying direct. Applying direct gets you one insurer’s current view, and if the answer is a decline you carry it into every future application. An adviser who places business across the market knows roughly where each insurer sits, and can test a difficult case anonymously before anyone signs anything.

Every New Zealand insurer writes underwriting to its own wording, and the words are where the money is. Two policies that look identical on price can pay very differently when it matters. Closing that gap is the entire job of an adviser.

• A pre-assessment can be run without your name attached, so a negative response from one insurer does not become a recorded decline.
• The adviser assembles the evidence — the right specialist letter, the right test results — before the underwriter has to ask, which changes the tone of the assessment.
• If an offer comes back loaded or excluded, an adviser can put the same file in front of another insurer whose current appetite is different.
• Advisers see the pattern across many cases and know which insurers have recently moved on a condition — something no published guide can tell you.
• Where cover has to be split across two insurers to get the best total outcome, an adviser can structure and manage that.
• An adviser will also tell you when to wait. Applying three months after a resolved investigation sometimes turns an exclusion into standard terms.

There are three ways to buy life cover in New Zealand, and they are not equivalent. You can buy direct from one insurer, which means you see one product range and one underwriting appetite. You can buy through your bank, which usually means a single insurer’s product sold under the bank’s brand, often with narrower definitions. Or you can go through an adviser, who quotes several insurers at once and is required to put your interests first.

The premium you pay is the same either way. Insurers build adviser commission into their pricing whether or not an adviser is involved, so going direct does not get you a discount — it just removes the person whose job is to argue your corner at application and at claim time.

• An adviser can see which insurer is currently taking your health history on standard terms, and which one will load or exclude it.
• An adviser can structure cover across two insurers if that produces a better outcome than putting everything with one.
• An adviser handles the underwriting back-and-forth, and is the person who chases the claim when a family is least able to.
• An adviser has to document why the recommendation suits you, which is a written record you can hold them to.

We are a referral service, not an insurer. We do not quote premiums and we do not sell policies. What we do is put you in front of one licensed New Zealand adviser who can compare the market properly.

1. 1

   You tell us what you are looking at

   The form takes about a minute. Nobody asks for your medical history on a web form — that conversation happens with the adviser, properly, and only once you have decided to proceed.

2. 2

   An adviser calls you

   A licensed New Zealand adviser talks through your situation: who depends on you, what you owe, what you already have in place, and what you are actually worried about.

3. 3

   They compare the market

   The adviser quotes across the major insurers, checks which of them will take your health history on the best terms, and puts the options side by side in writing.

4. 4

   You decide, in your own time

   There is no obligation and no cost to you. If the answer is that you already have enough cover, a good adviser will tell you that.
