Health and underwriting

Heart conditions and insurance underwriting

A cardiac history is one of the areas where underwriting is most evidence-driven and most insurer-specific. Time since the event, the investigations on file and the current specialist position do most of the work.

In short

  • Expect a detailed cardiac questionnaire and a request for specialist reports and investigation results.
  • Time since the event is the single most influential factor in most cardiac rating tables.
  • Recent events usually produce a deferral, not a decline — insurers wait for the position to settle.
  • Trauma cover is where a cardiac history bites hardest, because heart events are core listed conditions.
  • Terms range from a loading through cardiovascular exclusions to a decline, depending on the whole file.
  • Appetite in this area moves as reinsurers revise their view, so an old answer is not a current one.

What this is, plainly

Cardiac underwriting is detailed because insurers have a great deal of claims data and a great deal of clinical information to work with. Where a heart condition has been investigated, there is usually a specialist report, an imaging result and a treatment record — and underwriters would far rather assess those than a summary written by an applicant.

The pattern across the market is that recent events are deferred and older, stable, well-documented histories are rated. An application made a few months after a significant cardiac event is very likely to be postponed to a review date rather than refused. That is a timing decision, and it is worth understanding as such rather than reading it as a rejection.

What is asked and what is requested

The follow-up questions are among the longest in any application.

  • The exact diagnosis, the date, and the clinician who made it.
  • What investigations were done and what they showed.
  • What treatment or procedure was carried out, and when.
  • Current medication and whether it has changed.
  • Frequency of specialist review and the date of the most recent one.
  • Whether you have returned to full normal activity and to work.
  • Other cardiovascular factors — blood pressure, cholesterol, build, smoking, family history.

Evidence commonly requested

  • A cardiologist’s report, usually the most recent one.
  • Investigation results and any procedure record.
  • Full GP notes rather than a summary.
  • Occasionally a further cardiac test arranged and paid for by the insurer.
A cardiac history across the four products
Cover typeHow this history usually lands
Life coverOften available once sufficient time has passed, usually with a loading.
Trauma coverThe most affected product; cardiovascular conditions are commonly excluded.
TPDAssessed on the whole file; availability varies widely.
Income protectionFrequently restricted, with a cardiovascular exclusion or a decline both realistic.

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

What tends to improve the position over time is the passage of time itself, combined with a documented return to normal activity, a settled medication regime, no further events or admissions, and a recent specialist letter confirming a stable position. Insurers also read the surrounding risk factors as part of the same assessment, so changes recorded in build or smoking status are relevant to how the file is viewed.

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 a deferral after a recent event is normal and usually converts to an offer later.
  • Whether an exclusion is written narrowly to the diagnosis or broadly across the cardiovascular system.
  • That trauma cover and life cover will be answered differently, sometimes very differently.
  • That a specialist letter in the file at the outset changes the tone of the assessment.
  • That any existing cover you already hold is now extremely valuable and should not be cancelled.

Where an adviser makes a difference

Every New Zealand insurer writes applications with a cardiac history 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.

  • Cardiac appetite is one of the most variable things in the New Zealand market and moves with reinsurance treaties.
  • An adviser can pre-assess anonymously so that testing several insurers does not create a decline record.
  • Assembling the cardiology report and investigation results before applying materially improves the process.
  • Where trauma cover is unavailable, an adviser can look at what a life or TPD structure can achieve instead.
  • An adviser can advise on when to apply — sometimes waiting for a scheduled review is worth several months.

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

Can I get life insurance after a heart attack in New Zealand?

In many cases yes, once enough time has passed and the position is documented as stable. Insurers commonly defer applications made soon after a cardiac event and reassess later. Terms usually involve a loading, and the range of outcomes between insurers is unusually wide.

Why does a heart condition affect trauma cover more than life cover?

Because heart attack and related conditions are core listed events in a trauma policy. Insuring someone against a lump-sum payment for exactly the condition they already have is a very different proposition from insuring their life, so exclusions are common on trauma while life cover may still be written.

What is a cardiac deferral and how long does it last?

It is a postponement while the insurer waits for the position to settle and for review evidence to exist. The insurer will state a review point. Most deferrals of this kind end in an offer when you reapply with the specialist evidence they asked for.

What evidence do insurers want for a heart condition?

Usually the most recent cardiologist’s report, the investigation results, the treatment or procedure record, full GP notes and current medication details. Supplying these at the outset shortens a process that otherwise runs for months.

Does a heart condition affect my existing life insurance policy?

No. A policy already in force cannot be re-rated, restricted or cancelled because your health changed afterwards — that is precisely what you bought. This is why existing cover should be protected rather than replaced when a cardiac event occurs.
