Types of cover

Life cover vs mortgage-specific cover

You can insure a mortgage with an ordinary life policy or with a product designed around the loan. The ordinary life policy is usually more flexible, more portable and no more expensive.

In short

  • Plain life cover sized to the mortgage clears the debt on death and leaves any surplus to your family.
  • Mortgage-specific life cover is often decreasing, following the loan balance down.
  • Decreasing cover is cheaper but leaves nothing spare at the point the family needs flexibility.
  • Lender-arranged cover may be assigned, so the benefit reduces the loan rather than reaching your family.
  • Ordinary life cover is portable across lenders, houses and refinances.
  • Level cover with periodic reviews is usually the better structure, and reducing it later is always possible.

What this is, plainly

A mortgage is a debt, and a life policy is a sum of money. If the sum of money is at least as large as the debt, the debt can be cleared — it does not matter whether the policy has the word mortgage in its name. What differs between the two routes is flexibility, portability and who controls the money.

Mortgage-specific life cover is frequently structured as decreasing term: the sum insured falls each year in line with an assumed amortisation schedule. It is cheaper, because the average sum insured over the term is lower. It is also rigid, because it assumes your loan will reduce on schedule, that you will not top it up, and that your family needs the debt cleared and nothing else.

Plain level life cover sized to the mortgage at the start does something better. As the loan reduces, the surplus grows — and that surplus is what a surviving partner lives on while deciding whether to keep the house, move, or stop work for a year. Insurance that clears the debt and leaves nothing else has solved the bank’s problem rather than the family’s.

Deciding how to structure it

Two ways to insure the same debt
Decreasing mortgage coverLevel life cover
Sum insuredFalls with the assumed loan balanceStays as set until you change it
CostLowerHigher, but you keep the surplus
If you top up the loanCover may no longer match the debtSurplus absorbs it, up to the sum insured
If you refinance or moveMay end with the loanContinues unchanged
Who controls the moneySometimes the lender, by assignmentYour estate or beneficiary

There is one honest argument for decreasing cover: affordability. If the choice is between decreasing cover you can pay for and level cover you cannot, take the decreasing cover. But price both before deciding, because the gap is often smaller than expected — and reducing a level policy later is always possible, while increasing one requires underwriting.

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.

  • Whether the policy is level or decreasing, and what schedule a decreasing policy assumes.
  • Whether the policy is assigned to the lender, and what that means for who receives the money.
  • Whether the cover ends when the loan is repaid or refinanced.
  • Whether the terminal illness benefit is included and what life expectancy it requires.
  • Whether the sum insured can be increased later without underwriting after a mortgage top-up.
  • Who is nominated to receive the payment, and whether that nomination is current.

Where an adviser makes a difference

Every New Zealand insurer writes mortgage protection in new zealand 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.

  • Special events benefits allow cover to be increased without medical evidence after a mortgage increase — an option that mortgage-specific products may not include.
  • An adviser can compare a lender’s product against the wider market on both wording and price, which the lender cannot.
  • Where an existing bank policy is in force, an adviser will confirm the new cover is issued before anything is cancelled.
  • Structuring life cover to sit above the mortgage rather than exactly on it is a small change with a large effect on the family’s options.

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

  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 it better to use life insurance or mortgage insurance for a home loan?

Ordinary level life cover sized to the loan is usually the better structure. It is portable across lenders and houses, the money goes to your family rather than the bank, and any surplus as the loan reduces is exactly what a household needs alongside a cleared mortgage.

Should mortgage life cover decrease with the loan?

Only if affordability requires it. Decreasing cover is cheaper but assumes your family needs the debt cleared and nothing more. Level cover leaves a growing surplus as the loan reduces, and you can always reduce the sum insured later without underwriting.

Will the bank get my life insurance payout?

Only if the policy is assigned to the lender. A personally owned policy pays your estate or nominated beneficiary, who then decides whether to clear the loan. Ask who owns and who benefits from any cover arranged through a lender.

What if I increase my mortgage later?

If your policy includes a special events or future insurability benefit, you can usually increase the cover without medical evidence within a short window of the loan increase. Without that benefit, an increase requires a new application and fresh underwriting.

Does life cover pay out if I am terminally ill rather than dead?

Most New Zealand life policies include a terminal illness benefit that advances the sum insured when a specialist certifies a life expectancy below a stated period, commonly 12 months and sometimes 24. That can allow a mortgage to be cleared before death.
