Compare insurers
Westpac Life vs Asteron Life
The comparison people expect is about price. The one that matters is about portability: whether the policy is yours, or arranged around a loan you may not keep.

In short
- Westpac Life offers cover under a bank brand, almost certainly underwritten by a third-party licensed insurer.
- Asteron Life is a licensed New Zealand insurer distributing the core risk range through advisers.
- A bank channel offers one insurer’s product; an adviser quotes a panel.
- Cover arranged around a loan may reduce with the balance, be assigned to the lender, or end on refinance.
- Income protection is often the cover a working household needs most, and bank ranges are frequently narrower on it.
- Insurance is not a condition of getting a home loan.
What this is, plainly
Westpac Life offers life and related cover under a bank brand, with the risk typically carried by a third-party licensed insurer. Asteron Life is a licensed New Zealand life insurer writing life, trauma, TPD and income protection through Registered Financial Service Providers.
The difference that costs people most is not price. It is what happens to the cover when the mortgage changes. A policy you own continues regardless of who holds your lending. Cover arranged around a specific loan can reduce as the balance falls, be assigned to the lender, or terminate on refinance — and refinancing is exactly the moment when nobody is thinking about their life insurance.
The second difference is scope. A bank channel shows you one insurer, and often a narrower version of that insurer’s range, particularly on income protection and own-occupation TPD.
The six things that actually differ
Six questions. The first two are the ones that get skipped.
| What differs | What to ask | Why it matters |
|---|---|---|
| Portability | Does this cover survive a refinance to another lender, unchanged? | Cover that ends when your loan moves leaves you re-applying at an older age and current health. |
| Ownership and beneficiary | Do I own the policy, and does the money go to my family or to the lender? | Cover that pays the bank clears a debt. Cover that pays your family gives them the choice. |
| Who underwrites | Which licensed insurer carries the risk on the bank product, and which dispute scheme applies? | It is the entity whose wording and claims decisions apply to you. |
| Income protection | Is it available, on what definitions, and how does the offset clause treat ACC? | For a working household this is usually the most important cover and the one most often missing. |
| Sum insured shape | Does the cover reduce with the loan balance, and did I choose that? | Reducing cover is cheaper and leaves nothing spare once the debt is cleared. |
| Underwriting basis | Fully underwritten, or simplified with a general pre-existing condition exclusion? | It decides whether you learn what is covered at application or at claim. |
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.
- That personal insurance is not a condition of lending in New Zealand.
- Whether a banking package discount is conditional on keeping the policy.
- Whether the same underwriter offers a broader wording through advisers.
- Whether the occupation class assumed matches what you actually do.
- Whether you were given time to read the wording before signing.
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 arranges cover you own, which survives a change of lender and can be reviewed when the mortgage changes.
- An adviser is not on the other side of your lending decision, which removes an obvious conflict.
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
Will my bank life insurance continue if I move my mortgage?
It depends entirely on how the policy is written. Cover that is genuinely your own policy continues regardless of who holds your lending. Cover arranged around a specific loan may reduce, be assigned to the lender, or terminate on refinance. Ask for the answer in writing before you sign, because discovering it at refinance means applying again at an older age.
Is Asteron Life available through banks or only through advisers?
Asteron Life distributes through Registered Financial Service Providers rather than selling direct to the public. Because distribution cost is built into rates either way, using an adviser does not make the cover more expensive — it changes who compares the market and who handles the claim.
Does bank cover include income protection?
Sometimes, and often in a narrower form than a fully advised product. Income protection is the most technically complicated cover in the suite, and its value depends on the offset clause, the waiting and benefit periods and how partial disability is measured. Ask whether it is offered and compare the definitions before assuming it is equivalent.
Should mortgage cover reduce as the loan reduces?
It is cheaper if it does and less useful. The purpose of the cover is to keep a household in a house, not simply to extinguish a debt. Level cover sized to the original loan leaves a growing surplus as the balance falls, and that surplus funds the years afterwards. If budget forces reducing cover, take it — but make it a decision.
Can I keep my bank loan and insure elsewhere?
Yes. A lender can require you to insure the property, but personal cover on your life, health or income is your choice and can be arranged with any insurer. Declining the bank’s insurance has no bearing on a lending decision, and you are entitled to take the wording away and decide later.
