Health and underwriting

Type 1 diabetes and insurance underwriting

Type 1 is underwritten separately from type 2, on its own rating basis. Cover is regularly written in the New Zealand market, but the spread of outcomes between insurers is wider here than for almost any other condition.

In short

  • Insurers rate type 1 on its own table, not the type 2 one. The questions asked are similar; the pricing is not.
  • Age at diagnosis, duration, current management approach and whether related conditions are recorded all feature.
  • A specialist report is more likely to be requested than for type 2.
  • Life cover is commonly available with a loading. Income protection is frequently excluded or declined.
  • Continuous monitoring and pump therapy are asked about and are relevant to how an underwriter reads the file.
  • This is a condition where the difference between the best and worst insurer response is very large.

What this is, plainly

New Zealand insurers assess type 1 as a distinct risk with its own questionnaire and its own rating basis. The practical effect is that the answers a person with type 1 gets bear little relation to what someone with type 2 is offered, and applicants who read general diabetes guidance often arrive with the wrong expectations in both directions.

The core of the assessment is the management record. Underwriters want to see a long, consistent, well-documented pattern of review and stability, and they want it from a clinician rather than from the applicant. A file that includes a recent specialist letter is treated very differently from one that consists of a tick box and a date.

The shape of the assessment

The questions follow the diagnosis rather than the label, and they go further than the type 2 set.

  • Age at diagnosis and years since.
  • Current management approach, including whether a pump or continuous monitoring is used.
  • Frequency of review and which clinician provides it.
  • Recent results, usually across several time points rather than one.
  • Whether any related eye, kidney, nerve or circulatory findings are recorded.
  • Any hospital admissions related to the condition, and when.

Evidence commonly requested

  • A specialist or diabetes clinic report, requested more often than for type 2.
  • Full GP notes rather than a summary, in many cases.
  • A run of recent laboratory results rather than a single figure.
Type 1 diabetes across the four products
Cover typeHow this history usually lands
Life coverRegularly available with a loading, with the level varying widely by insurer.
Trauma coverSometimes available, often with related conditions excluded.
TPDAssessed cautiously; availability depends heavily on the wider file.
Income protectionThe hardest of the four. Exclusions and declines are common.

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

What underwriters look at over time is duration with stability — years of consistent review, no new related findings, no admissions, and no long gaps in the record. Because the rating tables for type 1 have moved considerably over the past decade as reinsurers have revised their view, a decline or a heavy loading from several years ago is worth revisiting rather than treating as settled.

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 type 2 answer tells you nothing about what you will be offered on type 1.
  • Whether an exclusion covers the diabetes only or all related conditions.
  • That gaps in the review record read poorly, even where nothing was wrong.
  • That income protection may need to be replaced with TPD or trauma cover rather than fought for.
  • That an older decline should be retested, because appetite in this area has changed.

Where an adviser makes a difference

Every New Zealand insurer writes applications involving type 1 diabetes 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.

  • The gap between the most and least generous insurer on type 1 is large enough to change the entire outcome of an application.
  • An adviser can approach several underwriters anonymously with a summary and compare indications before any record exists.
  • Where income protection is unavailable, an adviser can build an alternative structure from TPD, trauma and mortgage repayment cover.
  • An adviser will make sure a specialist report is in the file at the outset rather than four weeks in.
  • Terms declined some years ago are worth re-testing, and an adviser will know whether the market has moved.

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

Is type 1 diabetes underwritten differently from type 2?

Yes. Insurers use a separate questionnaire and a separate rating basis, so outcomes for the two are not comparable. Reading general diabetes information can leave people expecting either better or worse terms than they will actually be offered.

Can someone with type 1 diabetes get life cover in New Zealand?

It is regularly written, usually with a loading. The level of that loading varies more between insurers for type 1 than for almost any other condition, which makes comparing the market unusually valuable here.

Do insurers ask about insulin pumps and continuous glucose monitoring?

Yes. They are part of the standard question set because they tell the underwriter about the management approach and the level of clinical involvement. Answer them factually — this is information the underwriter uses, not a test you pass or fail.

Why is income protection so hard to get with type 1 diabetes?

Because income protection insures time away from work, which is a broader and more frequent event than death. Where an insurer will accept a loaded life risk, it may not accept the same file for a monthly disability benefit. This is an underwriting judgement about claim frequency, not a comment about the person.

Should I reapply if I was declined for insurance with type 1 diabetes years ago?

It is worth having the case retested. Reinsurer views on type 1 have changed over the past decade and insurer appetite has moved with them. Have an adviser pre-assess anonymously first, so testing the market does not create a second recorded decline.
