Health and underwriting

Asthma and insurance underwriting

Asthma is one of the most common disclosures and one of the least consequential for most applicants. The assessment turns on how it is controlled, not on the diagnosis.

In short

  • Insurers ask about medication, frequency of symptoms, and any hospital or urgent care attendance.
  • Well-controlled asthma on standard preventer treatment is frequently accepted at standard rates.
  • Hospital admissions, oral steroid courses and time off work are the details that change the assessment.
  • Smoking status is read alongside asthma and materially affects the outcome.
  • A GP report is often requested, mainly to confirm the medication and consultation pattern.
  • Income protection may attract questions where symptoms have caused time away from work.

What this is, plainly

Asthma is on a very large number of New Zealand applications and in most cases it changes nothing. Underwriters distinguish between a controlled condition managed on routine preventer treatment and a pattern involving frequent symptoms, escalating medication, urgent care attendance or time off work. Those sit at different places in the rating table.

The single biggest interaction is with smoking. Asthma in a non-smoker with settled treatment is usually a non-event. The same asthma alongside a smoking history is assessed considerably more cautiously, and that combination is where loadings appear.

The questions and what they establish

The follow-up set is short and focused on control.

  • When it was diagnosed and whether it is childhood or adult onset.
  • What medication you use, including preventers and relievers, and how often.
  • How frequently you have symptoms.
  • Whether you have had any hospital or urgent care attendance, and when.
  • Whether you have needed oral steroid courses, and how often.
  • Whether you have taken time off work because of it.
  • Your smoking and vaping status.

Evidence commonly requested

  • A GP report confirming the medication and consultation record.
  • Occasionally lung function results where the picture is more involved.
Asthma across the four products

Income protectionStandard in most cases; rated where symptoms have caused time away from work.

General market practice, not a rule. Appetite differs by insurer and changes over time.

What underwriters look at over time is a settled medication regime, a low frequency of symptoms, no urgent care attendance and no time off work in the record. Smoking status is read alongside, and a documented change there is one of the clearest things that alters the combined assessment. A loading applied to a more involved picture is worth revisiting once there is a longer settled record.

Not sure what cover you actually need?

That is the question an adviser is there to answer. Tell us your situation and a licensed New Zealand adviser will compare the market and come back with a written recommendation — including where you can cut cover you do not need.

No cost to you and no obligation. General information only — not personalised financial advice.

What to watch for

These are the details that decide whether the cover does what you expected. Read them before you compare on price.

  • That the assessment is about control, not the diagnosis itself.
  • That hospital and urgent care attendances are asked about specifically and will appear in your notes.
  • That smoking status interacts with asthma more than with most other conditions.
  • That childhood asthma with no current treatment is still disclosable.
  • That frequent reliever use is a question, and an honest answer is better than an optimistic one.

Where an adviser makes a difference

Every New Zealand insurer writes applications involving asthma 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.

  • Insurers set their thresholds for asthma differently, particularly where a smoking history sits alongside.
  • An adviser can present the medication and consultation record clearly rather than leaving it to be inferred.
  • Where a loading is applied for a more involved picture, an adviser can diarise a review.
  • For applicants who have stopped smoking, an adviser knows which insurers recognise that soonest.

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.

What happens if you get in touch

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.

Frequently asked questions

Does asthma affect life insurance premiums in New Zealand?

For most people, no. Well-controlled asthma on routine treatment is frequently accepted at standard rates. Loadings appear where the record shows frequent symptoms, escalating treatment, urgent care attendance or time off work — and particularly where a smoking history sits alongside.

Do I need to disclose childhood asthma?

Yes, if the question asks about it, which most do. A childhood diagnosis with no current treatment is generally a very mild factor, but it is still material and it will usually appear in your records.

Will an insurer ask for lung function tests for asthma?

Sometimes, where the disclosed picture is more involved or where the sum insured is large. In most straightforward cases a GP report confirming medication and the consultation record is enough.

Does asthma affect income protection?

It can, where the record shows time away from work. Income protection underwriting asks about work absence directly, so an asthma history that has never affected work is generally assessed much more lightly than one that has.

How much does smoking change an asthma assessment?

Considerably. Asthma in a non-smoker with settled treatment is usually a non-event, while the same asthma alongside a smoking history is assessed far more cautiously. The two are read together rather than separately.
