How Life Insurance Underwriting Works in NZ (2026): From Application to Decision

Underwriting is how a NZ insurer decides whether to offer you cover, on what terms, and at what price. Here is what insurers ask, when they request a medical or GP report, how long it takes, and how an adviser helps the result land in your favour.

Underwriting is the step between asking for life insurance and being offered it. It is where a New Zealand insurer looks at your health, history and circumstances, then decides whether to offer cover, on what terms, and at what price. For most people it is straightforward and quick. For others it involves a phone interview, a medical, or a report from their GP. This guide explains what insurers ask, what triggers extra evidence, how long it usually takes, and where an adviser can make the process smoother and the result better.

TL;DR: Underwriting is how a NZ insurer assesses your health and risk before offering life cover. Most applications complete in about 2-3 weeks ¹, with no-evidence cases sometimes settled in days and fully underwritten cases (medical or GP report) taking around 2-6 weeks ². Providing your medical information upfront is the single biggest thing that speeds it up ¹. Whether a claim is later paid still depends on the policy terms and your disclosure.

What is underwriting and why does the insurer do it?

Underwriting is the assessment an insurer carries out before it agrees to cover you. Life insurance pools risk across many people, so the insurer needs a fair picture of the risk each applicant brings before setting a price. Without that, premiums could not be priced sensibly and the people who are healthier would end up subsidising risks that were never disclosed.

In practice, underwriting answers three questions: will we offer this cover, on what terms, and at what premium. The insurer weighs your age, health, medical history, occupation, pastimes and family history against its published underwriting criteria ⁸. A clean, low-risk application is often accepted at standard terms with little fuss. A more complex one may need more evidence before the underwriter can decide.

It is worth being clear about one thing from the start. Underwriting happens at the application stage so that, when a claim comes, the insurer is not re-investigating your health from scratch. That is why full and accurate disclosure now is what protects a claim later. Whether a claim is ultimately paid depends on the terms, conditions, exclusions, stand-down periods and underwriting of the specific policy, and on your disclosure. This is a summary only — always read the policy wording or product disclosure statement.

What information does a NZ insurer ask for on a life application?

Most of the assessment comes from the application form and a personal statement about your health. You will typically be asked about:

• Personal details — age, sex, and contact information.
• Smoking and nicotine use — whether you currently use, or have recently used, cigarettes, vapes or other nicotine products.
• Height and weight — used to calculate your body mass index (BMI).
• Medical history — current and past conditions, surgeries, medications, and recent tests or specialist visits.
• Family history — certain conditions in close relatives, such as heart disease, stroke, cancer or diabetes, where they appeared at a younger age.
• Occupation — some jobs carry higher injury or illness risk.
• Pastimes and travel — activities such as diving, aviation or motorsport, and time spent in higher-risk regions.
• Alcohol and other lifestyle factors.

The personal statement and application form are time-limited. Under one major NZ insurer's underwriting guide, a completed personal statement is valid for 90 days, after which a Declaration of Continued Good Health is needed, and a full new application is required after 12 months ³. That matters if your application stalls — leave it too long and you may have to update or redo parts of it.

The level of detail asked usually scales with your age and the amount of cover. A modest sum insured for a healthy 30-year-old asks less than a large sum insured for someone in their 50s. Naming the product type correctly matters too — life cover, trauma and total and permanent disability (TPD) cover are underwritten against different criteria, even on the same application.

When will they request a medical, blood test or GP report?

Many applications are decided on the form alone. Extra evidence is requested when something in your answers, your age, or the amount of cover crosses an insurer's threshold. Common triggers include a large sum insured, older age, a disclosed condition that needs clarifying, or a borderline result that the underwriter wants to confirm.

The usual forms of additional evidence are:

A PMAR — a Private Medical Attendant's Report — is a summary the insurer requests from your GP, drawn from your medical notes. It is one of the most common reasons an application takes longer, because it depends on your doctor's turnaround rather than the insurer's. The same applies to medicals and blood tests: the more evidence required, the longer the decision tends to take.

If you are reapplying or your application drags on, the validity periods above come back into play. Bloods and exams generally hold good for 12 months, but an abnormal blood result may need repeating sooner ³.

How long does underwriting usually take in NZ?

Most New Zealand life insurance applications complete underwriting within about 2-3 weeks ¹. The single biggest factor is how much evidence the underwriter has to gather, and how quickly third parties — usually GPs — respond.

As a rough guide:

• No additional evidence required — a clean application can sometimes be decided in a few days to about a week ².
• Fully underwritten — where a medical exam or GP report is needed, expect roughly 2-6 weeks, with doctor or GP turnaround being the main cause of delay ².

The most effective way to keep things moving is to provide your medical information upfront with the application. Doing so reduces the back-and-forth caused by underwriters having to request more evidence after the fact ¹. These are general timeframes, not promises — individual cases vary with complexity, the insurer, and how responsive medical providers are.

What decisions can an underwriter make besides yes or no?

It is a common misconception that underwriting is pass or fail. In reality there are four broad outcomes, and most non-standard cases land somewhere between a clean acceptance and an outright decline:

• Standard terms — cover offered at the normal price for your age and profile.
• Loading — cover offered, but at a higher premium to reflect added risk (often expressed as a percentage, for example "+50%").
• Exclusion — the policy is issued, but claims relating to a specific condition or activity are not covered, while everything else is.
• Decline — the insurer will not offer that cover type, or defers a decision until more information is available.

An exclusion is not the same as a decline. Plenty of people hold valuable cover with one condition carved out and everything else fully protected. Terms can also be revisited later — if your health or circumstances improve, it can be worth asking the insurer to reassess a loading or exclusion at review time.

Whatever the outcome, the offer comes with a policy wording that sets out exactly what is and is not covered, including stand-down periods and exclusions. Reading that wording before you accept is part of the job. Once you accept the offer and the insurer confirms cover, the policy is in force.

How do height, weight, smoking and family history affect the outcome?

These are some of the most common factors that move an application off standard terms, and each is judged on detail rather than the label.

Height and weight (BMI). Insurers use BMI as one risk indicator. A modestly raised BMI on its own is often a small loading or no change; a very high BMI, especially alongside other factors such as high blood pressure, has a larger effect because the risks compound. Each insurer publishes its own thresholds in its product underwriting guide ⁸.

Smoking and nicotine. Smoker status has one of the clearest effects on premium. To be classed as a non-smoker, applicants generally need to be completely nicotine-free for at least 12 months ⁴. Vaping and e-cigarettes are treated the same as smoking, and an insurer may require a cotinine (COTS) test to confirm your status ⁴. If you have given up, this is worth knowing: former smokers who have been completely smoke-free, including vape-free, for 12 months are generally eligible to ask their insurer to reclassify them from smoker to non-smoker, which can lower premiums ⁵.

Family history. Certain conditions in close relatives — heart disease, stroke, some cancers, diabetes — can affect terms, particularly where they appeared at a younger age. Family history tends to nudge rather than decide an outcome, and it is weighed alongside your own health.

The common thread is that underwriters price the detail and the combination, not the diagnosis on its own. A single, well-managed factor is treated very differently from several stacked together. Because each insurer sets its own criteria and weights these factors differently ⁸, two insurers can reach different answers on the same person — which is exactly why where you apply matters. We cover that in how advisers compare insurers in NZ.

How can an adviser speed up and improve your underwriting result?

An adviser's value in underwriting is partly speed and partly placement. Because advisers can access insurers' underwriting and appetite guides, they can anticipate likely outcomes before an application is ever lodged ⁸. In practice the process tends to run like this:

1. Build the full picture first — conditions, dates, readings, medications and any earlier insurance decisions, the same detail an underwriter will eventually want.

2. Pre-assess before applying — an informal, no-names enquiry to insurers tests likely terms without lodging a formal application, so early declines don't pile up on your record.

3. Place the application with the right insurer — because appetite varies, the case goes to the insurer most likely to offer acceptable terms for your profile.

4. Submit medical information upfront — front-loading evidence is what cuts the back-and-forth and the delays ¹.

5. Manage the file — chasing GP reports, adding context, and answering underwriter questions so the assessment is complete and accurate.

6. Review the offer in full — comparing terms, loadings, exclusions and wording before you accept.

There is also a duty behind that work. Under the financial advice regime — in force since 15 March 2021 under the Financial Services Legislation Amendment Act 2019 ⁷ — an adviser must give priority to your interests where there is a conflict, take reasonable steps to ensure you understand any limits on the advice (for example that it covers only certain providers), and not give information that is false or misleading ⁶. A comparison form carries none of those duties.

Two further points sit alongside this. Full, accurate disclosure during underwriting is what protects a future claim — leaving things out is one of the fastest ways to have a claim challenged, which we cover in non-disclosure and life insurance claims. And once cover is in place, structuring it properly — ownership, beneficiaries and how it is split — is its own job, set out in how an adviser structures life cover.

We work with a panel of selected insurers, listed in our disclosure, rather than every provider in the market. We're generally paid by commission from the insurer when you take out a policy through us; this doesn't change the premium you pay, and we manage any conflicts of interest in line with our duty to prioritise your interests — full details are in our disclosure.

Frequently asked questions

How long does life insurance underwriting take in NZ?

Most applications complete within about 2-3 weeks ¹. A clean application needing no extra evidence can sometimes be decided in a few days to a week, while a fully underwritten case requiring a medical or GP report typically takes around 2-6 weeks ². Providing your medical information upfront is the best way to keep it moving ¹.

Will I need a medical or blood test for life insurance?

Not always. Many applications are decided on the form alone. A medical exam, blood test or GP report (PMAR) is usually requested when the sum insured is large, you are older, or a disclosed condition needs clarifying. The more evidence required, the longer the decision tends to take ²³.

How do insurers decide if I'm a smoker or non-smoker?

To be classed as a non-smoker you generally need to be completely nicotine-free for at least 12 months ⁴. Vaping is treated the same as smoking, and an insurer may ask for a cotinine (COTS) test to confirm ⁴. If you have been smoke-free and vape-free for 12 months, you are generally eligible to ask your insurer to reclassify your status, which can lower premiums ⁵.

What can an underwriter decide besides accepting or declining me?

Four outcomes are common: standard terms, a loading (a higher premium), an exclusion (a specific condition or activity is carved out, everything else covered), or a decline. Many non-standard cases end in a loading or exclusion rather than a decline, and terms can sometimes be reviewed later if your health improves.

Does it matter which insurer I apply to?

Yes. Each insurer underwrites against its own published criteria and weights factors like BMI, smoking and family history differently ⁸, so two insurers can reach different answers on the same person. Placing an application where it is most likely to succeed — rather than applying blind — is a key part of what an adviser does.

How long is my application valid if underwriting drags on?

Validity periods apply. Under one major NZ insurer's guide, a personal statement is valid for 90 days (after which a Declaration of Continued Good Health is needed) and a full new application is required after 12 months; medical exams and blood tests are valid for 12 months, with abnormal bloods repeated sooner ³. Front-loading your evidence helps avoid hitting these limits.
