What affects life insurance costs with diabetes?

With diabetes, a life insurer usually adds a loading, which is a percentage on top of the standard premium. The only NZ insurer position we found published is Chubb Life's: Type 1 diabetes is most commonly offered life cover only, with a loading of at least 100%, and a Type 2 diagnosis made around age 60 that is well controlled may carry 50 to 75%. Other insurers publish no figures, and your own terms come from underwriting.

In short

What a loading is

A loading is an extra percentage on the standard rate. A 100% loading doubles the standard premium; a 50% loading adds half. Insurers can also respond to an existing condition by adding a stand-down period or excluding the condition permanently or for a set time, and Asteron says it can usually still offer cover that way (Asteron). Which response you get depends on the insurer and on you.

What Chubb Life publishes

Chubb Life's underwriting article for advisers is the only public statement with loading figures that we found. The other insurers' guidance did not give them, so this is one insurer's position, not a market range.

Situation What Chubb Life says
Type 1 diabetes Most commonly offered life cover only, with a loading of "at least 100%". Other benefits are the exception, for example when diagnosed at 40 or over, well controlled and without complications.
Type 2 diabetes Terms depend on control, age at diagnosis and duration. A younger diagnosis means a higher loading.
Type 2, diagnosed later Someone diagnosed at about 60, with good control and no complications, "may have a loading of 50-75%".
Recent Type 2 diagnosis Cover is often deferred for 12 months to assess understanding, compliance and blood sugar control.
Pre-diabetes Terms rest on current and past HbA1c results. If results suggest diabetes is possible but it is not diagnosed, cover will likely be deferred until investigated.
Gestational diabetes Medical records are needed. Standard life terms are possible once they show good control or full recovery.

Chubb adds that BMI, smoking status, cholesterol, liver function, blood pressure and other conditions also affect terms, and that GP medical records are usually required. It recommends a pre-assessment conversation with an underwriter for anyone with diabetes. Fidelity Life says a pre-assessment is not an offer of cover and not a binding final assessment (Fidelity Life underwriting guide).

What a loading does to a premium: an illustration

QuoteHub's Premium Index prices standard rates only, without loadings. For $500,000 of stepped life cover at age 50, non-smoker, class 1 occupation, the range across the six insurers priced on 8 September 2026 was $90 to $120 monthly for a man and $80 to $100 for a woman (Premium Index; method on the methodology page).

The table applies percentages to those ranges. It is arithmetic on the Index, rounded to the nearest dollar. It is not an insurer's offer, and it does not say what loading you would be given at 50.

Loading Man, $500,000, age 50 (monthly) Woman, $500,000, age 50 (monthly)
None (standard) $90 to $120 $80 to $100
50% $135 to $180 $120 to $150
75% $158 to $210 $140 to $175
100% $180 to $240 $160 to $200

These are stepped premiums, so they rise each year with age, and a loaded premium rises from a higher base. We do not publish a 10-year total because we have no sourced step rates.

A fully underwritten policy and Quick Life, side by side

The two routes treat diabetes differently. The first prices it; the second does not ask about it, and limits cover for the first 2 years instead.

Fully underwritten, through an adviser Momentum Quick Life
Ages Varies by insurer 18 to 65
Health questions Yes; GP records usually required for diabetes None
What diabetes does to the price May add a loading, a deferral, an exclusion, or a decline Nothing; the premium uses age, gender, smoking status and cover amount
Cover amount Varies by insurer $50,000 to $300,000, with 3% increases each anniversary to a $500,000 cap per life
Premium shape Stepped or level, depending on the insurer Stepped to age 75, then fixed
First 2 years Terms as offered Accidental death and new conditions are covered. Pre-existing conditions and suicide are excluded.
Diabetes-related death in that window Depends on the terms offered No benefit; premiums are refunded if death is from a pre-existing condition and no claim is payable
After 2 years Terms as offered Pre-existing conditions covered, except a few that can be permanently excluded in the policy schedule

Quick Life's wording defines a pre-existing condition as illness, a condition or symptoms in the 2 years before cover starts, and says it includes "very high blood pressure, cholesterol over 7.0, a BMI over 40, or complications related to diabetes" (Momentum Life: Quick Life Insurance Policy Wording, November 2025). Diabetes treated in the 2 years before the start appears to fit that definition, and Momentum decides at claim time. On that reading, a death from diabetes or a related complication in the first 2 years is not paid. The 2 years restart if you cancel and rejoin, so do not cancel other cover until the window has passed.

Which route costs less is a question only quotes answer. A healthy person can usually get more cover for less with fully underwritten cover through an adviser. For someone with diabetes we publish no comparison, because the underwritten price depends on a loading we cannot predict.

Why complete answers matter

Underwriters price what you tell them, and a loaded price assumes your answers are complete. IFSO reported a case in which the insurer applied 50% loadings retrospectively after a non-disclosure finding and paid a reduced stroke claim (IFSO). The Contracts of Insurance Act 2024 changes how misrepresentation is judged from 15 November 2027 (not yet in force). Until then, answer every question fully.

Frequently asked questions

Can I get life insurance with Type 1 diabetes?

Chubb Life says it is most common to offer life cover only, with a loading of at least 100%, and other benefits only in rarer cases. Other insurers publish no position. Guaranteed acceptance asks no health questions, with the 2-year limit above.

What if I was diagnosed recently?

Chubb Life says a recent Type 2 diagnosis often means cover is deferred for 12 months. Pre-diabetes without a diagnosis may also be deferred until investigated.

Does Quick Life ask about diabetes?

No. Quick Life has no health questions. Its wording treats complications related to diabetes as a pre-existing condition, which is not paid if death results from it in the first 2 years.
