Insurance Underwriting in NZ: What Happens After You Apply

You have decided to get life insurance, income protection, or trauma cover. You have filled in the application form, answered dozens of personal questions, and hit submit. Now what?

For most New Zealanders, the underwriting process is a complete black box. Your application disappears into the insurer's system and you wait, sometimes for weeks, with little idea of what is happening behind the scenes. This guide changes that. Here is a transparent, step-by-step look at how insurance underwriting works in New Zealand, what the possible outcomes are, and how you can give yourself the best chance of a smooth result.

What Is Underwriting?

Underwriting is the process a New Zealand insurance company uses to assess the risk of insuring you, with an underwriter reviewing your application, medical history, occupation and lifestyle to decide whether cover is offered and on what terms. Every personal insurance application in New Zealand goes through underwriting, and the assessment ends in one of five possible outcomes.

Every personal insurance application in New Zealand goes through underwriting. It is how insurers make sure they are charging a fair premium that reflects the actual risk, rather than applying a one-size-fits-all price. Without underwriting, premiums would need to be much higher across the board to account for unknown risks.

The Underwriting Process: Step by Step

Underwriting in New Zealand follows five steps, starting with the application form and detailed health and lifestyle questions, then a GP report or medical examination where required, followed by assessment by the underwriter and the decision. Health questions typically span the last five years in detail, and medical examinations become more likely as the sum insured rises, with each insurer setting its own threshold.

Step 1: The application form

Everything starts with the application form. This is far more detailed than most people expect. You will be asked about:

• Your personal details (age, gender, residency status)
• Your occupation and daily duties
• Your medical history, including past and current conditions, surgeries, medications, and GP visits
• Your family medical history (parents, siblings)
• Your lifestyle, including smoking, alcohol consumption, recreational drug use, and hazardous activities
• Your travel plans, particularly to high-risk countries
• Your financial situation (for income protection and high-sum-insured applications)

The application form is the foundation of the entire underwriting process. The more complete and accurate your answers, the smoother the rest of the process will be.

Step 2: Health and lifestyle questions

Within the application, the health section is the most detailed. You will typically be asked about conditions and symptoms spanning the last five years, with broader questions covering your lifetime medical history. Common areas include:

• Heart and circulatory conditions
• Cancer history
• Mental health conditions (depression, anxiety, and others)
• Musculoskeletal issues (back pain, joint problems)
• Respiratory conditions
• Neurological conditions
• Diabetes and metabolic conditions
• Any symptoms you have experienced but not yet had investigated

Insurers also ask about lifestyle factors: how much you exercise, your height and weight (to calculate BMI), whether you smoke or vape, how much alcohol you drink, whether you participate in activities like skydiving, motorsport, or scuba diving, and whether you have any upcoming travel to regions with elevated health or security risks.

Step 3: GP report or medical examination

Depending on your answers and the amount of cover you are applying for, the insurer may request additional medical information. This usually takes one of two forms:

GP report (Attending Physician's Statement). The insurer writes to your GP requesting your medical records for a specified period. This is the most common form of additional evidence. It typically covers the last five years and includes details of consultations, diagnoses, test results, referrals, and prescriptions.

Medical examination. Above a certain sum insured, which each insurer sets for itself and which is typically lower for trauma and income protection than for life cover, the insurer may require you to attend a medical exam. This can include blood tests, a urine sample, blood pressure readings, an ECG, and a physical examination conducted by a nurse or doctor arranged and paid for by the insurer.

Some insurers also use telehealth assessments, where a nurse calls you to go through your medical history in detail over the phone.

Step 4: Assessment by the underwriter

Once the underwriter has all the information they need, they assess your application against the insurer's risk guidelines. They consider:

• Your health history. Current and past conditions, how well they are managed, and the statistical risk they represent.
• Family history. A family history of cancer, heart disease, or other serious conditions can influence the outcome, particularly for trauma and life cover.
• Occupation. Manual or hazardous occupations carry higher risk than office-based roles. Trades, farming, and emergency services roles may attract loadings or specific terms.
• BMI. Insurers use height-to-weight ratios as one indicator of health risk. A BMI outside the normal range may trigger additional questions or a loading.
• Smoking and vaping. Smokers pay significantly higher premiums across all types of personal insurance. Most insurers classify anyone who has smoked or vaped in the last 12 months as a smoker.
• Lifestyle and hobbies. High-risk activities like aviation, motorsport, rock climbing, and diving can result in exclusions or loadings.
• Travel. Extended or frequent travel to countries with limited healthcare infrastructure or elevated security risks may affect your terms.
• Financial profile. For income protection, the insurer will verify your income to ensure the benefit amount is appropriate. For very high sums insured, they may also ask for evidence of financial justification.

The underwriter weighs all of these factors together. Two people with the same condition can receive different outcomes depending on their overall profile.

Step 5: The decision

After completing their assessment, the underwriter issues a decision. There are five possible outcomes.

Possible Underwriting Outcomes

New Zealand underwriters issue one of five decisions on an insurance application: standard terms, a loading, an exclusion, a deferral, or a decline. A loading raises the premium by a percentage such as +50% or +75%, an exclusion removes claims arising from a specific condition, and a deferral asks you to reapply after a set period. Loadings and exclusions can be combined.

It is worth noting that loadings and exclusions can be combined. You might receive an offer with a 50% loading and an exclusion for a specific condition. Your adviser can help you understand whether this represents a reasonable outcome or whether it is worth approaching a different insurer.

A decline from one insurer does not mean all insurers will decline you. Different companies have different risk appetites and underwriting guidelines. This is one of the key reasons to work with an licensed financial adviser who understands the market.

What Underwriters Are Really Looking At

Underwriters in New Zealand look for stability and management rather than reasons to decline, and the vast majority of applications are accepted on standard or near-standard terms. Well-managed conditions with stable test results, consistent treatment compliance and improving markers such as lower blood pressure or better HbA1c are viewed favourably, and some insurers review a loading after three years of stable health.

Here is what matters most:

• Stability and management. A well-managed chronic condition with stable test results is viewed very differently from an uncontrolled condition with complications.
• Time since diagnosis or treatment. The longer ago a condition was diagnosed and resolved, the more favourably it is viewed. Many insurers will review loadings or exclusions after a specified period.
• Compliance with treatment. Underwriters look positively on applicants who follow their treatment plans, attend regular check-ups, and take prescribed medication consistently.
• Trends. Improving health markers (weight loss, lower blood pressure, better HbA1c levels) work in your favour.

If you have a pre-existing condition, it does not automatically mean you will face higher premiums or exclusions. It means the underwriter needs enough information to assess the risk fairly.

How Long Does Underwriting Take?

Underwriting in New Zealand takes one to three business days for simple applications with no medical issues, two to four weeks for standard applications requiring a GP report, and four to eight weeks for complex cases involving specialist reports or high cover amounts. The GP report is the single biggest source of delay.

Simple applications (no medical issues, younger applicant, moderate cover amount): These can be assessed in as little as one to three business days, sometimes on the same day through digital underwriting platforms.

Standard applications (minor medical history, GP report required): Typically two to four weeks. The main delay is usually waiting for your GP to return the medical report.

Complex applications (significant medical history, specialist reports required, high cover amounts): Four to eight weeks is not uncommon. Multiple specialist reports, additional testing, and internal referrals to senior underwriters can all extend the timeline.

The single biggest source of delay is the GP report. Some medical practices take two to three weeks to process insurer requests, and if the report comes back incomplete, the insurer may need to go back for further information.

How to Speed Up the Process

Completing the application in full, pre-arranging your GP report, and responding quickly to underwriter queries are the fastest ways to shorten an insurance application in New Zealand. Because some medical practices take two to three weeks to process an insurer's request, asking your GP practice in advance to prioritise the report removes the largest single delay.

1. Complete the application thoroughly. Answer every question in full. Vague or incomplete answers trigger follow-up queries, which add days or weeks to the process.
2. Pre-arrange your GP report. Ask your GP practice in advance if they can prioritise the insurer's report request. Some practices offer faster turnaround if you let them know a request is coming.
3. Respond quickly to queries. If the underwriter asks for additional information, respond as soon as possible. Every day of delay on your side adds to the overall timeline.
4. Gather documents in advance. If you know you have a complex medical history, have recent test results, specialist letters, or discharge summaries ready to provide.
5. Work with an adviser. An experienced adviser knows what information underwriters need and can help you present your application in the most complete way from the start, reducing back-and-forth.

Your Duty of Disclosure

When you apply for insurance in New Zealand, you have a legal obligation to disclose all information that is relevant to the insurer's decision. Under the Contracts of Insurance Act 2024, this means you must answer all questions on the application form honestly and completely.

What you must disclose:

• All medical conditions, past and present, whether or not you think they are relevant
• Any symptoms you have experienced, even if you have not seen a doctor about them
• All medications you take, including over-the-counter and supplements prescribed by a doctor
• Any specialist consultations, investigations, or referrals
• Lifestyle factors such as smoking, recreational drug use, and hazardous activities
• Occupation details, including any hazardous aspects of your work

What happens if you do not disclose?

Non-disclosure can have serious consequences. If the insurer discovers that you withheld or misrepresented material information, they can:

• Void your policy from the start date, as though it never existed
• Decline a claim, even if the claim is unrelated to the undisclosed information
• Refuse to pay out to your beneficiaries

The consequences are particularly severe if the non-disclosure is found to be deliberate. Even innocent non-disclosure can result in a claim being declined if the insurer can demonstrate that they would not have offered cover, or would have offered different terms, had they known the full picture.

The simple rule: if in doubt, disclose it. Let the underwriter decide whether it is relevant. Your adviser can help you understand what needs to be disclosed and how to present the information clearly.

Digital Underwriting: Faster Decisions for Simple Cases

Several New Zealand insurers now use digital underwriting platforms that assess straightforward applications in real time and issue an immediate or same-day decision, replacing manual assessment by a human underwriter. Digital underwriting typically suits applicants under 45 years of age with no significant medical history, moderate cover amounts, low-risk occupations and no smoking history.

Digital underwriting typically works for applicants who:

• Are under 45 years of age
• Have no significant medical history
• Are applying for moderate cover amounts
• Work in low-risk occupations
• Do not smoke

If you meet these criteria, your application may be assessed in real time as you complete the online form, with a decision issued at the end. No GP report, no waiting, no back-and-forth.

However, digital underwriting has limitations. If your application triggers any flags (medical history, high cover amount, hazardous occupation), it will be referred to a human underwriter for manual assessment. Digital underwriting also varies significantly between insurers. Some have invested heavily in this technology, while others still rely primarily on manual processes.

Your adviser can tell you which insurers offer digital underwriting and whether your application is likely to qualify.

The Role of Your Adviser

A licensed financial adviser plays a significant role in New Zealand underwriting even though the insurer makes the final decision, pre-assessing your application, choosing the insurer most likely to offer favourable terms, preparing and tracking the application, negotiating loadings or exclusions, and explaining the outcome. Advisers are paid by the insurer, so using one costs you nothing extra.

• Pre-assesses your application. Before submitting, your adviser reviews your situation and identifies potential issues. They can advise on which insurer is most likely to offer favourable terms for your specific profile.
• Prepares your application. A well-prepared application with complete, clear answers reduces the chance of delays and follow-up queries.
• Manages the process. Your adviser tracks the progress of your application, follows up with the insurer and your GP, and keeps you informed.
• Negotiates on your behalf. If the insurer offers terms you are unhappy with (for example, a loading or exclusion), your adviser can negotiate, provide additional evidence, or submit your application to a different insurer.
• Explains the outcome. Underwriting decisions can be confusing. Your adviser translates the insurer's response into plain English and helps you understand your options.

Frequently Asked Questions

Can I be declined for insurance in New Zealand?

Yes. Insurers can decline applications if the risk is assessed as too high. However, a decline from one insurer does not mean all insurers will decline you. Different companies have different risk appetites, and an adviser can help you find the right fit. For more on how conditions are assessed, see our guide to insurance with pre-existing conditions.

Does my GP report cost me anything?

Usually, no. The insurer covers the cost of requesting your GP report as part of the underwriting process. However, some GP practices may charge a fee for copying or summarising medical records. Check with your practice if you are unsure.

What if I forgot to mention something on my application?

Contact your adviser or the insurer as soon as possible to add the information. It is much better to correct an omission before your policy is issued than to have it discovered at claim time. Honest mistakes can usually be resolved without issue if addressed promptly.

Will a loading or exclusion last forever?

Not necessarily. Some loadings and exclusions are reviewed after a set period. For example, an insurer might apply a loading for a recently diagnosed condition but agree to review it after three years of stable health. Your adviser can negotiate review terms as part of the application process.

Can I apply to multiple insurers at the same time?

You can, but it is generally more effective to have your adviser identify the most suitable insurer for your profile first. Applying to multiple insurers simultaneously means multiple GP report requests and medical exams, which can be time-consuming and may not improve your outcome. A targeted approach, guided by an adviser who knows the market, is usually more efficient.

What is the difference between a loading and an exclusion?

A loading increases your premium to reflect higher risk, but you still have full cover. An exclusion means a specific condition or cause of claim is not covered, but your premium may remain at standard rates. Some policies have both. See our insurance jargon guide for more definitions.

Does digital underwriting mean I do not need an adviser?

Digital underwriting speeds up the assessment process, but it does not replace the advice component. An adviser helps you understand how much cover you need, which type of cover is appropriate, and which insurer suits your profile. The underwriting method is just one part of the process.
