Health and underwriting

Fertility treatment and insurance underwriting

Fertility treatment is a disclosable medical history like any other. Life cover is commonly issued on ordinary terms, while benefits sensitive to a foreseeable short-term claim are more often deferred until treatment concludes.

In short

  • Insurers ask what treatment is under way or has been completed, and when.
  • Any underlying condition identified during investigation is assessed on its own terms.
  • Life cover is usually available on ordinary terms.
  • Income protection is the benefit most likely to be deferred while treatment is in progress.
  • Where a pregnancy results, the usual temporary pregnancy restrictions apply.
  • Applying with a temporary restriction is generally better than waiting uninsured.

What this is, plainly

Insurers treat fertility treatment as a medical history to be disclosed and assessed, not as a category that raises questions about you. What an underwriter wants to establish is what treatment is under way or has been completed, whether any underlying condition was identified during investigation, and whether a pregnancy is currently in progress.

The underlying condition, where one has been identified, is usually the substantive part of the assessment. Fertility investigation sometimes identifies a condition that would be underwritten in its own right regardless of the context, and it is that condition rather than the treatment which drives the terms.

What is asked and how it is handled

The questions are practical and are aimed at the current position.

  • What treatment is under way or has been completed, and the dates.
  • Whether any underlying condition has been identified during investigation.
  • Whether any medication is currently prescribed.
  • Whether a pregnancy is currently in progress.
  • Whether any complications have been recorded.
  • Where income protection is applied for, your current earnings and work pattern.

Evidence commonly requested

  • A GP report, and a specialist report where an underlying condition has been identified.
  • Occasionally results relating to that condition rather than to the treatment itself.
Fertility treatment across the four products
Cover typeHow this history usually lands
Life coverUsually available on ordinary terms, subject to any underlying condition.
Trauma coverUsually available; an identified underlying condition is assessed on its own basis.
TPDUsually available on the same basis.
Income protectionThe benefit most likely to be deferred while treatment is in progress.

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

Deferrals in this area are timing decisions. Insurers prefer to assess a disability benefit once a treatment cycle has concluded and the position is settled, and they will state when to return. Where an underlying condition has been identified, the assessment of that condition follows its own rules and its own timeline, quite separately from the fertility treatment itself.

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 an underlying condition identified during investigation is assessed in its own right.
  • That a deferral on income protection is about timing rather than about the treatment.
  • That any resulting pregnancy brings the usual temporary pregnancy restrictions.
  • That life cover is usually available now rather than after treatment concludes.
  • That waiting to apply means being uninsured in the meantime.

Where an adviser makes a difference

Every New Zealand insurer writes applications during fertility treatment 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 differ on how they handle applications during active treatment, particularly for income protection.
  • An adviser can sequence benefits so cover is put in place where it is available now.
  • Where an underlying condition has been identified, an adviser can make sure it is presented with the right evidence.
  • An adviser can diarise the point at which a deferred benefit should be reapplied for.

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

Do I have to tell an insurer I am having fertility treatment?

Yes. It is a medical history like any other and it will appear in your records. Disclosure is straightforward and, for life cover, usually makes no difference to the terms offered.

Can I get life insurance during IVF treatment?

In most cases yes, on ordinary terms, subject to any underlying condition identified during investigation. It is generally the disability benefits rather than life cover that are affected by treatment being in progress.

Why is income protection deferred during fertility treatment?

Because insurers prefer to assess a disability benefit once a treatment cycle has concluded and the position is settled. It is a timing decision, the insurer will say when to return, and it is not a comment on the application.

Does an underlying fertility-related condition affect my cover?

Where investigation has identified a condition, that condition is assessed in its own right on its own rules — separately from the fertility treatment. It is usually the substantive part of the assessment, and it may require its own evidence.

What happens to my application if I become pregnant during the process?

The usual approach to applications during pregnancy applies: life cover generally proceeds on ordinary terms, a temporary pregnancy-related restriction may be applied to some benefits, and income protection may be deferred until a period after the birth.
