Life stages

Life insurance for first home buyers

Buying a house converts a manageable life into a six-figure obligation with your name on it. The insurance question is not whether you need cover — it is which cover, sized how, and bought from whom.

In short

  • A mortgage is usually the first debt large enough that the family cannot absorb it if one income stops.
  • The bank will offer you cover at or near settlement. That is one insurer’s product sold under the bank’s brand, not a comparison.
  • You are not required to buy the bank’s insurance to get the loan. Declining it does not affect your approval.
  • Decreasing cover sized to the loan is cheap; level cover sized to the household is what most families actually need.
  • Get underwritten before you go unconditional, not after. If your health complicates the application, you want to know while you still have options.
  • Two borrowers usually need two policies, not one joint policy — the loan does not halve when one of you dies.

What this is, plainly

The mortgage is the event that turns life insurance from a theoretical good idea into an arithmetic problem. Before the loan, a household without dependants can usually absorb the loss of one income by moving, downsizing or leaning on family. After it, there is a fixed payment due on the same day every month for the next twenty-five to thirty years, and the bank has security over the roof.

The cover that answers that problem is not complicated. Enough life cover that the loan can be cleared or reduced to a level the survivor can service on one income. Enough income protection that a long illness does not force a sale. Usually some trauma cover, because the most common threat to a young household’s finances is not death — it is a serious diagnosis that stops one of you working for a year while the mortgage keeps running.

What is complicated is the sales environment. Somewhere between conditional approval and settlement, a bank or mortgage adviser will raise insurance. That conversation happens when you are exhausted, on a deadline, and inclined to sign whatever gets you the keys. It is the single worst moment in the whole process to make a twenty-year decision.

How to do this in the right order

The sequence matters more than the product choice, because the sequence is what protects your options. Underwriting takes time and can come back with terms you did not expect.

  1. 1Get pre-approval, then start the insurance conversation — before you find the house, if you can.
  2. 2Complete the application and let the insurer underwrite you while you are still house-hunting. Underwriting is free and does not commit you to anything.
  3. 3If an insurer comes back with a loading, an exclusion or a request for GP notes, you now have weeks to shop it rather than days.
  4. 4Set the start date to align with settlement, so you are not paying premiums on a mortgage you do not yet have.
  5. 5Once you are unconditional, confirm cover is in force before settlement day. Cover in force means the insurer has accepted, not that you have submitted a form.

Decreasing cover or level cover

Decreasing cover tracks down alongside the loan balance, so it is cheap and it always matches the debt. The problem is that clearing the mortgage is not the same as replacing a parent. A family with a mortgage-free house and no income has solved one problem and kept the other.

The usual answer for a household with children, or planning them, is level cover sized to the mortgage plus a few years of income, held long enough to matter. If money is tight at the start, take a smaller level sum insured rather than a larger decreasing one — you can add to level cover later, and the health you have at 28 is the best you will ever have to buy with.

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 you are offered at settlement is life cover on you, or a payment-protection product that only covers the repayments for a set period.
  • Who owns the policy. If the bank is the owner or the loss payee, the money goes to the loan and not to your family’s choice.
  • Joint policies pay once. On a two-borrower loan, a single joint policy leaves the survivor uninsured at exactly the moment they need cover most.
  • Low-deposit lending sometimes comes with a lender’s mortgage insurance premium. That protects the bank, not you, and is not life insurance.
  • Whether the cover has a special events benefit letting you increase it without new medical evidence when you have a child or increase the loan.
  • Whether income protection has been sized against the mortgage payment alone or against your actual income. The first is usually not enough.

Where an adviser makes a difference

Every New Zealand insurer writes mortgage-related cover 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.

  • Underwriting appetite differs sharply between insurers on the health histories young buyers commonly have — mental health treatment, sports injuries, family history.
  • An adviser can time the application so cover starts at settlement rather than months earlier.
  • Splitting cover between two lives and two structures, part level and part decreasing, is where most of the savings on a first-home policy actually sit.
  • If the bank has already issued a policy, an adviser can compare it side by side and tell you honestly if it is fine — sometimes it is.

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 buy insurance from the bank to get my mortgage approved?

No. Lending decisions in New Zealand are made on your income, deposit and servicing capacity. A bank may raise insurance as part of the conversation, and it may feel connected, but declining the insurance does not change the loan approval. If you feel it does, ask for that in writing.

Should I insure the mortgage or insure my income?

Both, in that order of urgency but not of importance. Life cover clears the debt if you die. Income protection keeps the payments going if you cannot work, which is far more likely. A household with only one of the two has a visible gap.

When should I apply — before or after I find a house?

Before. Underwriting can take weeks if the insurer wants a GP report, and an unexpected loading or exclusion is much easier to handle when you are not counting down to settlement. Applying early costs nothing and you can set the start date later.

Is decreasing mortgage cover cheaper than level life cover?

Yes, meaningfully, because the insurer’s exposure falls every year. The trade-off is that it eventually reduces to very little, and it only ever solves the debt. It suits a couple with no children and a firm plan to be mortgage-free. It suits a young family less well.

We are buying together — one policy or two?

Two, in almost every case. The loan does not reduce by half when one borrower dies, so each of you needs cover sized to what the survivor would have to carry. A joint policy pays once and then ends, leaving the survivor to buy new cover at their new age and their new health.

What if one of us has a health condition?

Apply anyway, and apply early. Insurers differ enormously in how they treat the same history, and an adviser can approach the one most likely to accept it on standard terms. A loading on part of the cover is far better than the cover you did not apply for.
