Types of cover

Special events and future insurability

A special events benefit lets you increase your cover after a defined life event without answering health questions. It is free, it is under-used, and it expires quickly after the event that triggers it.

In short

  • Special events options allow an increase in cover without new medical underwriting.
  • Triggers typically include buying a home, increasing a mortgage, marriage, a birth or adoption, and a significant pay rise.
  • The window to apply is short — commonly 30 to 90 days from the event — and missing it forfeits the option.
  • Increases are capped, both per event and as a total across the life of the policy.
  • The increase inherits your existing policy terms, including any loading or exclusion already applied.
  • It is one of the few ways to grow cover after a diagnosis has made ordinary underwriting difficult.

What this is, plainly

A special events increase — some insurers call it future insurability or a guaranteed insurability option — is a promise made at the start of the policy: if a listed life event happens, you may increase your cover by a stated amount without providing any medical evidence. You still pay for the extra cover at your then-current age, but the insurer does not get to reassess your health.

It is valuable precisely because health rarely stays still. The person taking out cover at 30 is unlikely to be the same underwriting risk at 40, and the events that create the need for more cover — a bigger mortgage, a second child, a promotion — tend to arrive at the same time as the first health complications.

It is also routinely wasted, because the option is tied to a deadline nobody diarises. Settlement day comes and goes, the family moves house, and three months later the window has closed. This is the single most common piece of value that policyholders leave on the table.

Triggers, windows and caps

Common special event triggers
Typical triggerWhat usually needs to be shown
Buying a first or subsequent homeSale and purchase agreement or the loan offer
Increasing an existing mortgageThe bank’s revised loan documentation
Birth or adoption of a childBirth or adoption certificate
Marriage or civil unionMarriage certificate
A significant salary increaseEmployment letter or evidence of new income
Taking on business debtLoan agreement, often with a shareholding requirement

Triggers, evidence requirements and dollar limits are set by each insurer and differ. Check your own policy wording.

Two limits usually apply. There is a maximum increase per event — often expressed as a percentage of the original sum insured or a dollar cap, whichever is lower — and a lifetime maximum across all events. There is also typically an age limit, after which the option no longer operates at all.

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 exact list of qualifying events, which is not standard between insurers.
  • The number of days you have after the event to exercise the option.
  • The per-event cap and the lifetime cap on increases.
  • The age at which the benefit ceases to be available.
  • Whether existing loadings or exclusions carry across to the increase, which they usually do.
  • Whether the option is available on trauma and TPD benefits or only on life cover.

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.

  • Event lists, windows and caps differ enough that this benefit is worth weighting when choosing an insurer, particularly for people in their twenties and thirties.
  • An adviser who reviews annually will catch events you did not think to mention — a mortgage top-up is easy to forget.
  • Where health has changed, an adviser can compare exercising the option against a fresh application, since the option avoids underwriting but the fresh application might get better pricing.
  • Business events, such as taking on debt or increasing a shareholding, sometimes qualify under a separate business increase option.

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 a future insurability benefit?

A right, built into your policy at the start, to increase your cover after a defined life event without providing medical evidence. You pay for the additional cover at your current age, but the insurer does not reassess your health.

Which life events let me increase cover without underwriting?

Commonly buying a home or increasing a mortgage, marriage or civil union, the birth or adoption of a child, a substantial pay rise, and taking on business debt. Each insurer publishes its own list, and they are not identical.

How long do I have to use a special events option?

Usually between 30 and 90 days from the event. Miss the window and the option for that event is gone, although a later qualifying event may create a new one. Check your policy wording for the exact period.

Is there a limit on how much I can increase?

Yes, generally two: a maximum per event, often a percentage of the original sum insured or a dollar cap, and a lifetime maximum across all increases. There is also an age beyond which the option stops operating.

Will my existing exclusion apply to the increased cover?

Almost always. The increase is written on the same terms as the original policy, so a loading or exclusion applied at underwriting carries across. That is the trade-off for not being reassessed.
