Health and underwriting

Back injuries and insurance underwriting

This is the clearest example in underwriting of a history that is close to irrelevant for one product and decisive for another. A back injury rarely touches life cover. On income protection it frequently produces a spine exclusion that never comes off.

In short

  • Life cover is usually unaffected by a back injury history.
  • Income protection commonly carries a spine or musculoskeletal exclusion, and it is often permanent.
  • The wording is everything — a named disc is very different from “any condition of the spine”.
  • Physiotherapy, ACC claims and chiropractic treatment are all disclosable and all appear in records.
  • Surgery, time off work and recurrence are the details that widen an exclusion.
  • Some insurers exclude more narrowly than others, which is the whole argument for comparing.

What this is, plainly

Ask an underwriter what a back injury means and they will ask which product you are applying for. On life cover, the answer is usually nothing at all — a spine problem is very unlikely to be a cause of death, and it barely registers in the rating. On income protection, the answer is often an exclusion, because back problems are among the most frequent causes of time away from work in the country.

That asymmetry catches people out. Applicants who have had a manageable back problem for years are frequently surprised to be offered full life cover and an income protection policy with the spine written out of it. It is not inconsistent. It is two different products answering two different questions about the same history.

The exclusion is also usually permanent. Insurers review exclusions less readily than loadings, and a spine exclusion applied on income protection tends to stay. That makes the wording, at the moment it is first offered, one of the most consequential things in the whole application.

What is asked, and why the wording decides everything

Expect detailed questions and expect the record to be checked.

  • When the injury or first episode occurred, and how.
  • What treatment was given — physiotherapy, chiropractic, injections, surgery.
  • Whether an ACC claim was made, and when.
  • Whether there has been any recurrence, and how often.
  • How much time off work was taken, and when the most recent episode was.
  • Whether any imaging was done and what it recorded.
  • Your occupation, which weighs heavily on income protection.

Evidence commonly requested

  • A GP report covering consultations, referrals and treatment.
  • Imaging or specialist reports where they exist.
  • Occasionally an ACC claim history.
A back injury history across the four products
Cover typeHow this history usually lands
Life coverUsually standard rates. This history rarely affects life cover.
Trauma coverUsually standard, since spine conditions are not typically listed trauma events.
TPDOften restricted, since musculoskeletal problems are a recognised cause of permanent incapacity.
Income protectionThe decisive product. A spine or musculoskeletal exclusion is a very common outcome.

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

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.

  • The precise scope of any exclusion offered, including whether it extends to conditions “arising from” the injury.
  • That physiotherapy and chiropractic treatment are disclosable, and appear in records.
  • That an ACC claim history is a record the insurer can ask about.
  • That a spine exclusion on income protection is usually permanent.
  • That your occupation interacts with this history more than with almost any other.

Where an adviser makes a difference

Every New Zealand insurer writes income protection applications with a back 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.

  • Insurers word spine exclusions very differently, and the difference is worth more than any premium saving.
  • An adviser can obtain indicative wordings from several insurers before you commit to one.
  • Where a narrow exclusion is achievable, it is usually because someone asked for it with evidence attached.
  • An adviser can weigh whether a loading, where offered as an alternative, is better value than the exclusion.
  • After a long clear period with no treatment, an adviser can put a review request together.

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 a back injury affect life insurance in New Zealand?

Rarely. Life cover is usually issued at standard rates with a back injury history, because a spine problem is very unlikely to be a cause of death. It is income protection where this history matters, and it matters a great deal there.

Why does income protection exclude my back?

Because back problems are among the most common causes of time away from work. Income protection insures exactly that event, so an insurer looking at a documented back history will often remove it rather than price it. The rest of the policy continues to cover every other cause of disability.

Can a spine exclusion be removed after a few years?

It is harder than removing a loading and insurers grant it less often, but it is worth asking after a long documented period with no treatment, no consultations and no time off work. Expect a no more often than a yes, and ask what evidence would change the answer.

Do I have to disclose physiotherapy for my back?

Yes. Physiotherapy, chiropractic treatment and osteopathy are all disclosable, whether or not a diagnosis was made and whether or not you paid privately. They appear in referral records and in ACC histories, and an omission is far more damaging than the treatment itself.

How much does the wording of a back exclusion matter?

More than almost anything else in the policy. An exclusion naming a specific disc leaves most of your income protection working. One covering any musculoskeletal condition removes a large share of the claims the policy would otherwise pay. Ask for the exact words before you accept the offer.
