Compare insurers
Partners Life vs AIA
Both are large insurers with the full personal risk range. The differences that matter are in premium structure options, definitions and underwriting appetite — not in which brand you have heard of more often.

In short
- Both operate across life, trauma, TPD, income protection and health cover.
- Partners Life distributes through advisers; AIA reaches customers through advisers and through simpler entry-level products.
- If the AIA quote is an entry tier, it is not comparable to a full Partners Life product — establish which you are being shown.
- Premium structure options, especially the level expiry ages available and what happens at expiry, differ between insurers and matter over decades.
- Published price rankings place them differently at different ages, so no single table settles it.
- Underwriting appetite is the deciding variable for anyone with a health history, and it is not published by either.
What this is, plainly
Partners Life and AIA are both licensed New Zealand life insurers with the full personal risk range — life cover, trauma, TPD, income protection and health insurance. On paper the product lists look similar, which is exactly why comparing them on the product list is a waste of an afternoon.
The first practical difference is distribution. Partners Life reaches customers through Registered Financial Service Providers. AIA reaches customers both through advisers and, for simpler products, through more direct channels. That matters because an entry-level product is a narrower contract with simpler underwriting, and comparing it against a fully advised product will tell you the entry product is cheaper, which is true and beside the point.
Once you have established that you are comparing like with like, the real work is the wording and the underwriting. Both are technical, both are where claims are won and lost, and neither appears in a price table.
The six things that actually differ
Compare these six, in writing, for both insurers. Where the answers are equivalent, price decides. Where they are not, the difference is what you are paying for.
| What differs | What to ask | Why it matters |
|---|---|---|
| Premium structure | Which level expiry ages are offered, can part of a policy be level and part stepped, and does a level policy end at expiry or convert to stepped at attained age? | This choice usually costs more over a lifetime than the difference between the two insurers’ base rates. |
| Product tier | Is this quote the full product or an entry-level version, and which benefits and definitions are absent from the cheaper tier? | An entry product priced against a full one is not a comparison. It is two different contracts. |
| Terminal illness | Does the wording require a certified life expectancy under 12 months or under 24 months, and does the early payment reduce the death benefit? | The 24-month version pays earlier and is materially easier to meet. |
| Trauma structure | Are severity-based partial payments made for early-stage diagnoses, and is a buy-back available to reinstate life cover after an accelerated trauma claim? | Severity structures change what an early cancer is worth to you; a buy-back protects the life cover your family relies on. |
| TPD definition | Is own-occupation available for your occupation class, and at what age does the definition convert to any-occupation or an ADL test? | Own-occupation is far more useful, and the conversion age determines what you actually hold in your sixties. |
| Future insurability | Which life events trigger an increase without new medical evidence, what is the cap per event and in total, and at what age does it end? | This is the benefit that protects you against your own future health, and the limits are not standard. |
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 trauma cover quoted is standalone or accelerated, because accelerated trauma reduces life cover when it pays.
- Whether income protection is quoted as agreed value or indemnity — the price gap is large and the claim gap larger.
- Whether indexation is switched on by default, since CPI increases lift both cover and premium each year.
- The occupation class each insurer has assigned you, which drives income protection and TPD availability more than it drives life pricing.
- Whether any multi-policy discount is conditional on keeping both policies, and what happens if you cancel one.
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.
- Where one insurer applies a loading or exclusion, an adviser can put the same history to the other and to insurers outside this pair.
- An adviser can tell you whether an entry-level product closes the gap you actually care about, or whether the full product is worth the difference.
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
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
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
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.

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 Partners Life or AIA better for someone with a health condition?
Neither, universally. Both reinsure their risk, their reinsurers take different views of the same condition, and appetite changes as treaties are renegotiated. The only reliable way to find out is a pre-assessment that puts an anonymised summary of your history to both — and to other insurers — before any formal application exists.
Do Partners Life and AIA offer the same trauma conditions?
Their condition lists differ in both count and definition, and counts are close to meaningless because insurers group and split conditions differently. Compare the definitions of cancer, heart attack, stroke and coronary artery surgery, whether severity-based partial payments are made, and whether a buy-back is offered.
Can I buy AIA cover directly but Partners Life only through an adviser?
Partners Life distributes through Registered Financial Service Providers rather than selling direct to the public, while AIA reaches customers through advisers and, for simpler products, more directly. Because distribution cost is built into rates either way, buying direct does not usually save money — it changes who does the comparison and who handles the claim.
Which of Partners Life or AIA is cheaper for life cover?
It depends entirely on the profile. Published comparisons order insurers differently at different ages and smoking statuses, and a table built on a 30-year-old non-smoker tells you very little about a 55-year-old smoker. Get quotes on matched terms for your own circumstances rather than relying on any published ranking.
Should I split cover between Partners Life and AIA?
Sometimes that is the right structure — for example putting life cover with the insurer that prices it best and income protection with the one whose offset clause suits your ACC position. The trade-off is a second policy fee and the loss of multi-benefit discounts, so it needs to be modelled rather than assumed.
