Compare insurers

nib vs Southern Cross Life

Both come at insurance from the health side, and both offer life and living cover alongside it. The trap is comparing them as one thing when they are two decisions.

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

In short

  • nib operates primarily as a health insurer and also offers life and living cover.
  • Southern Cross Life & Living Insurance is sold under the Southern Cross brand and underwritten by Chubb Life.
  • Health cover and risk cover are different products with different underwriting and should be compared separately.
  • Non-Pharmac drug cover produces the largest single-claim differences between New Zealand health policies.
  • Health premiums are age-rated and repriced annually; life cover on a level structure behaves differently.
  • Switching health insurers restarts pre-existing condition assessment, which is why people stay put.

What this is, plainly

nib operates in New Zealand primarily as a health insurer, with a range extending to life and living or serious-illness cover. Southern Cross Life & Living Insurance is the life and living cover sold under the Southern Cross brand, and it is underwritten by Chubb Life.

So on one side of this comparison the brand and the risk underwriter are the same organisation, and on the other they are not. That is not a mark against either — brand and underwriter are separated all over the market — but it changes who you should be asking about wording and claims.

The bigger discipline is separating the two decisions. A health policy is judged on cover tier, non-Pharmac drug limits, specialist and diagnostic cover, excess structure and how premiums behave with age. A life or living policy is judged on definitions. The best answers are frequently at different companies.

The six things that actually differ

Run the health comparison and the risk comparison separately. These six cover both.

What actually differs, and what to ask
What differsWhat to askWhy it matters
Health cover tierBase surgical, or comprehensive with specialist consultations and diagnostics?The gap between the two tiers is where most unexpected health shortfalls appear.
Non-Pharmac drug coverIncluded or optional, and to what annual and lifetime limit?It is the benefit that produces the biggest single-claim differences between policies.
Pre-existing conditionsHow is pre-existing defined, how far back does it look, and can an exclusion be reviewed after good health?It is the clause that makes switching health insurers expensive later.
Risk underwriterWhich licensed insurer underwrites the life and living cover on each side?Southern Cross Life & Living is underwritten by Chubb Life, so that is the company assessing those claims.
Risk definitionsTerminal illness at 12 or 24 months, and how are the major trauma conditions defined?A serious-illness benefit and a full trauma product can read alike and pay very differently.
Premium behaviourWhat do the health premiums look like at 55, 65 and 75, and is the risk cover stepped or level?Two different pricing models sitting on one direct debit is how people get surprised.

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 a condition excluded on a health policy may still be accepted on risk cover, and the reverse.
  • That switching health insurers restarts pre-existing condition assessment at the new insurer.
  • Whether a member or multi-policy discount is conditional on holding both policies.
  • Whether the risk cover offered is fully underwritten or simplified.
  • Whether the maximum sums insured on the risk cover are enough for your mortgage and dependants.

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 compares health wordings on sub-limits and exclusions, which summaries do not describe accurately.
  • Before any health switch, an adviser can establish in writing which conditions would become pre-existing at the new insurer.

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

Is Southern Cross Life the same company as Southern Cross Health Society?

The life and living cover sold under the Southern Cross brand is underwritten by Chubb Life, which is a different company from the entity behind the health membership. If you are comparing risk cover, the underwriter is the company whose wording applies, whose underwriters assess your application and whose dispute resolution scheme you would use.

Which health insurer is better, nib or Southern Cross?

Neither in general. Compare the specific policies on cover tier, non-Pharmac drug limits and whether they are annual or lifetime, specialist and diagnostic cover, excess structure and how premiums behave at 65 and 75. Where those are equivalent, price and service decide; where they are not, the gap is what you are trading.

Should I hold health and life cover with the same brand?

Only if you would have chosen both wordings on their own merits. A multi-policy discount is real money, but health and risk cover are judged on entirely different criteria and there is no requirement to hold them together. Splitting lets you take the best of each rather than compromising for a discount.

Will switching health insurers cost me cover for existing conditions?

Usually yes. Switching restarts pre-existing condition assessment, so anything that has developed since you took the current policy is likely to be excluded at the new insurer. Get the new insurer’s exclusions in writing before cancelling anything, and ask whether cover can be transferred on existing terms.

Is living cover the same as trauma insurance?

Not necessarily. Serious-illness and living cover benefits vary in how many conditions they list and how those are defined, and are not automatically equivalent to a full trauma product. Compare the definitions of the major conditions, and check whether severity-based partial payments and a buy-back are offered.
