Getting cover

How to buy life insurance

There are seven decisions, and they have a right order. Most people start at the last one — which insurer — and work backwards, which is why so much New Zealand cover is the wrong size on the wrong structure.

In short

  • Decide what you are insuring against before you decide how much, and how much before you decide with whom.
  • There are three routes: direct from an insurer, through a bank, or through an adviser with a panel.
  • The premium is the same whichever route you take — commission is built into the rate table regardless.
  • Premium structure is the decision with the largest lifetime cost, and it is made in about ten seconds by most buyers.
  • Ownership and beneficiary nomination decide how fast the money reaches your family. They are not paperwork.
  • Full disclosure at application is what makes the policy payable. Nothing else you do matters as much.

What this is, plainly

Buying life insurance well is mostly about sequence. The market presents it as a shopping problem — compare prices, pick a brand — and that framing produces households with $250,000 of stepped life cover, no income protection and a $600,000 mortgage.

The order that works starts with the events you are insuring against, moves to the size of the loss each one would cause, then to the structure that keeps the cover alive long enough to be there, and only then to which insurer will write it best for you.

The other thing worth knowing before you begin is that the route you choose does not change the price. Insurers build distribution cost into their rate tables whether or not an adviser is involved. Going direct does not buy you a discount; it buys you the job of doing the comparison yourself.

The seven decisions, in order

  1. 1

    What are you insuring against

    Death, a serious diagnosis, being unable to work, or the mortgage specifically. Different products, different probabilities. Most households need more than one and can rarely afford everything at once.

  2. 2

    How much

    Debt to clear, plus income to replace for a defined number of years, plus final costs, less what you already hold. Do the arithmetic before you look at any price.

  3. 3

    For how long

    Take the later of the date your mortgage is repaid and the date your youngest child is independent. That is the horizon the cover has to survive.

  4. 4

    Stepped or level

    The decision with the biggest lifetime cost. Short horizons favour stepped; anything you intend to hold past your mid-fifties usually favours level. Ask for cumulative cost, modelled at more than 3% a year.

  5. 5

    Structure and ownership

    Accelerated or standalone trauma. Single or joint policies. Who owns the policy, and who is named as beneficiary. These decide how the money is taxed, who controls it, and how quickly it arrives.

  6. 6

    Which insurer

    On price for your profile, on the wordings that matter to you, and on which one will take your health history on the best terms. That last one is often decisive and is not published anywhere.

  7. 7

    Apply, disclose fully, and check the terms offered

    The offer of terms is the real contract, not the quote. Read the exclusions and loadings before you accept, and get written confirmation of the date cover starts.

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.

  • Buying the product you have heard of rather than the one you are most likely to claim on.
  • Choosing a sum insured that fits a monthly budget rather than the loss it is meant to cover.
  • Accepting stepped premiums by default because they are cheaper on the quote in front of you.
  • Leaving the beneficiary nomination blank, which sends the money through your estate and slows it down.
  • Rushing disclosure to hit a settlement date. This is the one shortcut that can cost the whole claim.
  • Cancelling existing cover before the new policy is confirmed in force.

Where an adviser makes a difference

Every New Zealand insurer writes life insurance 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.

  • An adviser runs the sequence in the right order, which is the single biggest determinant of whether cover works.
  • They can access a panel, so your health history is shopped rather than tested against one insurer’s appetite.
  • They handle ownership and beneficiary structuring, which most people get wrong and never find out about.
  • They are the person who presents the claim, which is when the quality of the original advice becomes visible.

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

What is the first step in buying life insurance in New Zealand?

Working out what you are insuring against and how large the loss would be. Everything else — insurer, price, structure — follows from that. Starting with a price comparison is the most common reason people end up with cover that is the wrong size.

Is it cheaper to buy life insurance direct?

No. Insurers build distribution costs into their rate tables whether or not an adviser is involved, so the premium is the same. What differs is whether anyone compares the market for you, explains the wording, and handles the claim.

What documents do I need to buy life insurance?

For a quote, nothing. For an application, identification, and for larger sums insured or self-employed income, financial evidence such as tax returns or financial statements. Medical records are requested by the insurer from your practice rather than supplied by you.

How long does the whole process take from start to cover?

A straightforward case can be days from application to policy issue. Add a week or two if blood screening is required, and several weeks if the insurer needs a report from your GP. The variable is your disclosure, not the insurer’s speed.

Can I buy life insurance for someone else?

You can own a policy on another person’s life if you have an insurable interest — a spouse, a business partner, a co-borrower — and that person consents and completes the health disclosure. Ownership decides who receives the money, so structure it deliberately.
