AIA vs AA Life

Both can be bought quickly. That similarity hides the more important question: whether the policy you end up with was individually underwritten, or sold with a general exclusion attached.

Last reviewed 4 September 2026 · Written and checked by the Best Life Insurance editorial team · How we get paid

In short

  • AIA operates across the full risk range and also sells simpler products through more direct channels.
  • AA Life sells under a consumer brand, with a licensed insurer underwriting the policy behind it.
  • Speed of purchase is not the same as breadth of cover — check which underwriting basis applies to each.
  • A general pre-existing condition exclusion is assessed at claim, not at application.
  • Maximum sums insured on simplified routes are commonly below what a mortgage requires.
  • Neither price nor brand tells you how your health history would be treated.

What this is, plainly

AIA is a licensed New Zealand life insurer with the full personal risk range, sold through advisers and, at simpler tiers, more directly. AA Life sells life and related cover under a familiar consumer brand, underwritten by a licensed insurer behind it.

Someone comparing these two is usually looking for a straightforward purchase. Both can provide one. The thing to check is what kind of contract the easy purchase produces, because there are two quite different models sitting under the same convenience.

In one, you answer detailed questions and an underwriter decides in writing what is covered and what is not, before you pay anything. In the other, you answer few questions and a general pre-existing condition exclusion sits in the wording, to be applied when you claim. Both are legitimate. Only one tells you where you stand in advance.

The six things that actually differ

Six comparisons, starting with the one that decides what you actually own.

What actually differs, and what to ask
What differsWhat to askWhy it matters
Underwriting basisIs the policy individually underwritten, or is there a general pre-existing condition exclusion in the wording?It decides whether you learn what is covered at application or at claim.
Who underwritesWhich licensed insurer carries the risk, and which dispute scheme applies?For a brand that is not itself the insurer, this is the company whose decisions matter.
Maximum sum insuredWhat is the highest cover available through each route?Simplified products commonly cap below the level a household with a mortgage needs.
Product tierIf this is AIA, is the quote for the full product or an entry tier, and what is missing from the cheaper one?An entry tier priced against a full product is not a comparison.
Stand-downs and renewabilityIs there a stand-down before full benefits apply, and is the cover guaranteed renewable?A stand-down means an early illness claim may return premiums rather than pay the sum insured.
Future insurabilityCan I increase cover after a life event without new medical evidence?If your needs will grow, a product without this benefit means re-applying at your future health.

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 words simplified, guaranteed acceptance and underwritten are being used precisely in the material you have been given.
  • How far back a general pre-existing condition exclusion looks.
  • Whether the sum insured available covers the mortgage plus income replacement.
  • Whether level premiums are available at all on either route.
  • That your duty of disclosure is identical however short the form is.

Where an adviser makes a difference

Every New Zealand insurer writes life and living 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.

  • An adviser quotes both insurers on matched terms — same sum insured, same structure, same waiting and benefit periods — which is the only way the numbers mean anything.
  • Where a health history is not straightforward, an adviser can pre-assess it anonymously with both insurers before any formal application exists, so an unfavourable answer never lands on your record.
  • Policy fees and multi-benefit discounts mean the cheaper per-benefit rate is often not the cheaper household total. An adviser models the total.
  • An adviser can run one fully underwritten quote alongside the simplified product so you can see whether standard terms are available to you.
  • Where full underwriting would accept a condition outright, that is almost always better than a general exclusion you never see applied until you claim.

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 difference between simplified and fully underwritten life cover?

Fully underwritten means an underwriter assesses your medical history at application and states in writing what is covered, what is excluded and what is loaded. Simplified means few or no health questions, with a general pre-existing condition exclusion applied at claim instead. The first tells you where you stand; the second defers the question to the worst moment.

Is AA Life easier to apply for than AIA?

Application length and underwriting depth vary by product and tier rather than simply by brand, and AIA itself sells at more than one tier. Ask each provider directly whether the specific product in front of you is individually underwritten or carries a general pre-existing exclusion, because that is what determines the answer.

Can a simplified policy be declined at claim time?

A claim can be declined if it falls within an exclusion, including a general pre-existing condition exclusion, or if there was material non-disclosure at application. That is precisely why full underwriting is worth the extra fortnight for most people: it converts an unknown into a written answer before you start paying premiums.

How much cover can I get without a medical?

It depends on your age and the insurer’s evidence limits, and it is usually well short of what a household with a mortgage needs. Ask each insurer what sum insured you can apply for before tests are required — that figure is knowable in advance, unlike underwriting appetite, and it often decides which route is realistic.

Does a well-known brand mean a better insurance policy?

No. What decides a claim is the policy wording, the underwriter’s assessment of it, and the dispute scheme behind that underwriter. Where the brand and the underwriter are different companies, brand familiarity tells you about the marketing rather than about the contract.
