Health Insurance Benefits and Limits Compared by Insurer - Southern Cross vs AIA vs nib vs Partners Life vs Unimed and more
Compare health insurance benefits from Southern Cross, AIA, nib, Partners Life and Unimed - we compare surgical limits, cancer cover, mental health and more side-by-side.
Updated 13 February 2026
Summary
Our guide covers:
- Health insurance policies are difficult to compare - our health insurance comparison shows the price differences, but there's a lot more to understand to make an informed decision.
- For example, two policies at similar prices can offer different benefit limits - it's only when you claim that you find out if you're covered. The fine print is critical to every health insurance policy.
- Based on our research for this guide, cancer treatment limits, mental health coverage, diagnostic testing restrictions, and overseas treatment options vary dramatically between insurers.
- We have analysed the published benefit maximums from five major health insurers and broken them down by benefit category, so you can see exactly what each insurer pays for specific treatments.
- Whether you are buying health insurance for the first time, reviewing your existing policy, or considering switching providers, this comparison helps you understand what you are actually paying for.
Our guide covers:
- Health Insurers We Compared
- Three Insurers Offering the Most Comprehensive Overall Coverage
- Insurer Profiles: Strengths and Limitations
- Benefit Comparisons by Category - Know This First
Know This First: The $2,000-$10,000+ you pay annually for health insurance buys you access to private treatment and lets you skip public waiting lists, which are at all-time highs. But not all policies are created equal:
- Some insurers offer unlimited surgical cover while others cap it at $600,000.
- Some cover mental health treatment while others exclude it entirely.
- Some will pay for treatment in Australia, while others will not.
- Our guide to explaining Southern Cross Health Insurance policy cost increases highlights the increasing costs insurers pay and why it's important to ensure you have sufficient cover.
- Understanding these differences before you buy - or before you need to claim - is critical to selecting the right policy.
Most New Zealanders overpay on health insurance every year simply because they don't compare prices or benefits.
- In the next 30 seconds, you can see real quotes from Southern Cross, AIA, nib and others - all side-by-side.

Health Insurers We Compared
This guide compares benefit limits from five major New Zealand health insurers and the various policies they offer. All insurers have investment-grade financial strength ratings, meaning they have the financial capacity to pay claims when you need them. The insurers we review and compare include:
Important: AA Insurance also offers health insurance, but its policy structure differs from those of the insurers listed above. For this reason, we have not included them in the detailed benefit comparisons.
A Note on How We Present Our Tables
- Southern Cross - New Zealand's largest health insurer with over 900,000 members, and known for its strong brand recognition.
- AIA - A global insurer with a strong presence in New Zealand, having acquired Sovereign Insurance in 2018. AIA is known for its comprehensive coverage options.
- nib - An Australian-owned insurer operating in New Zealand since 2012.
- Unimed - A New Zealand-owned cooperative insurer, known for unlimited surgical limits and straightforward pricing.
- Partners Life - A New Zealand-owned insurer focused on life and health products and well-known for comprehensive overseas treatment cover.
Important: AA Insurance also offers health insurance, but its policy structure differs from those of the insurers listed above. For this reason, we have not included them in the detailed benefit comparisons.
A Note on How We Present Our Tables
- The source data (LifeDirect/Quality Product Research) compares individual policies - for example, "Southern Cross Wellbeing One" versus "Southern Cross Wellbeing Two" or "nib Ultimate Health" versus "nib Ultimate Health Max".
- Each insurer typically offers a base hospital-only policy and a more comprehensive policy that adds Specialist & Tests cover.
- For readability, we've consolidated the PDF into an insurer-level comparison.
- Where we show a single figure, we've generally used the higher-tier policy (e.g., Wellbeing Two, Private Health Plus, Ultimate Health Max).
- Where limits differ significantly between tiers, we show a range.
- Why this matters to you: If you're comparing quotes, make sure you know which policy tier you're being quoted on. A "Southern Cross" quote could be Wellbeing One or Wellbeing Two - with meaningfully different benefits.
- Top Tip: Always confirm the specific policy name and check its benefit limits before purchasing.
Three Health Insurers Offering the Most Comprehensive Overall Coverage
Our research examines benefit limits across many categories, and we have shortlisted three insurers that stand out for offering the most comprehensive overall coverage. This does not mean they are right for everyone, or they offer the best value for money - your individual circumstances, health history, and budget are critical to making the right choice. We believe these three insurers consistently offer strong limits across multiple benefit categories.
1. AIA - Most Comprehensive Overall
AIA consistently delivers strong coverage across the widest range of categories.
Why we believe AIA stands out:
Where AIA falls short (compared to other insurers)
AIA may suit:

- People whose main concern is surgical treatment rather than ancillary benefits.
Our View
However, our research suggests leaders worth considering:
1) AIA offers the most comprehensive overall package for the majority of New Zealanders.
2) Southern Cross remains a sensible choice if you want solid core coverage without the extras.
3) Partners Life offers specific benefits that others do not match.
- Health insurance is not a one-size-fits-all product. We have not considered pricing in this guide because policy costs vary by age, risk, and lifestyle.
- The "right" insurer depends entirely on what matters most to you. A 30-year-old planning a family has different priorities than a 55-year-old concerned about cancer treatment.
However, our research suggests leaders worth considering:
1) AIA offers the most comprehensive overall package for the majority of New Zealanders.
- The combination of unlimited surgical cover and strong ancillary benefits, including pregnancy and fertility cover, makes it a solid offering.
- The lack of psychiatric hospitalisation cover is a notable gap, but their consultation cover benefit partially addresses this.
2) Southern Cross remains a sensible choice if you want solid core coverage without the extras.
- Their unlimited surgical and radiotherapy limits protect you against the most expensive treatments, even if the ancillary benefits are limited.
3) Partners Life offers specific benefits that others do not match.
- They offer the strongest protection for your family in worst-case scenarios - death benefits, overseas treatment for rare conditions, and mental health support.
Most New Zealanders overpay on health insurance every year simply because they don't compare prices or benefits.

Health Insurer Profiles - Strengths and Limitations
Each insurer has a distinct profile of strengths and weaknesses - it's important to understand these patterns and match an insurer to your priorities. The following profiles summarise what each insurer does well and where they fall short:
| Insurer | Financial Strength | Notable Strengths | Limitations |
|---|---|---|---|
| Southern Cross | S&P A+ (Strong) | Unlimited surgical, unlimited radiotherapy, competitive pricing, strong brand, $750 allergy services | Limited mental health, 6-month diagnostic restriction, no Australian treatment, no funeral benefit |
| AIA | Fitch AA (Very Strong) | Unlimited surgical, infertility cover, $500k non-surgical, 100% Australia cover | No skin lesion cover, no psychiatric hospitalisation, no funeral benefit, no allergy services |

Southern Cross
Southern Cross is New Zealand's largest and most recognised health insurer. Founded in 1961, they operate as a not-for-profit friendly society, which means any surplus goes back to members through better benefits or lower premiums rather than shareholder dividends.
Their Wellbeing One and Wellbeing Two policies serve as the basis for our comparison. Wellbeing Two adds Specialist & Tests cover to the base hospital policy. Both offer unlimited surgical procedures and unlimited radiotherapy - two of the most expensive potential treatments.

AIA
AIA is a global insurance group headquartered in Hong Kong, with operations across Asia-Pacific, including New Zealand. Their financial strength (Fitch AA rating) is among the highest of any insurer operating in New Zealand, providing strong assurance they will be around to pay claims.
Their Private Health and Private Health Plus policies offer what we consider the most comprehensive overall coverage in the market and are worth considering as part of any price and policy comparison.

nib
nib is an Australian-owned insurer that entered the New Zealand market in 2012 through acquisition. They bring scale and systems from their Australian operations, though their New Zealand-specific policy features sometimes differ from local competitors.
Partners Life
Partners Life is a New Zealand-owned insurer that has grown rapidly since launching in 2011. They focus on life and health insurance products and have built a reputation for comprehensive coverage and strong relationships with advisers.
Their Private Medical + S&T policy offers the strongest ancillary benefits in the market. The $60,000 limit for treatment unavailable in New Zealand is double what most competitors offer. The $10,000 funeral benefit is the highest.
The main weakness is diagnostic testing. Partners Life applies a 12-month restriction - the strictest in the market - meaning tests must occur within 12 months before surgery or serious illness diagnosis to be covered. Their surgical limit caps at $600,000 rather than being unlimited.

Unimed
Unimed is a New Zealand-owned cooperative insurer with a long history in the market. Unimed have a separate exclusions document. Here is a list of approved surgical procedures - if the surgery is not specifically on that list, it will not be covered.
Health Insurance Benefit Comparisons by Category - Know This First
The following sections break down specific benefit limits by category. We explain what each benefit means, why it matters, and how insurers compare. Use these comparisons to focus on the categories that matter most to your situation.
How to read these tables:
How to read these tables:
- Dollar amounts show the maximum the insurer will pay per policy year (unless stated as "lifetime" or "per event").
- "Covered" means the benefit falls under another limit (usually surgical or non-surgical) rather than having its own cap.
- "Not covered" means the insurer does not offer this benefit under any circumstances.
Cancer and Oncology Treatment Benefits
Cancer is the leading cause of death in New Zealand, and cancer treatment is often the most expensive medical care you can receive. A course of chemotherapy can cost $50,000 to $100,000. Radiation therapy can cost $20,000 to $50,000. Immunotherapy drugs can exceed $150,000. Understanding your cancer coverage is essential.
| Benefit | Southern Cross | AIA | nib | Partners Life | Unimed |
|---|---|---|---|---|---|
| Chemotherapy | $60,000 | Covered | Covered | Covered | $65,000 |
| Immunotherapy | Covered | Covered | Covered | Covered | Not covered |
| Brachytherapy | Covered | Covered | Covered | Covered | Not covered |
| Radiotherapy | Unlimited | Covered | Covered | Covered | $65,000 |
| Prophylactic Treatment | $40,000 lifetime (loyalty) | Covered | Not covered | Covered | $40,000 lifetime (loyalty) |
Know This: All insurers cover chemotherapy, but with different structures. Some insurers include chemotherapy under their general surgical or non-surgical benefits, without a specific chemo cap, meaning your overall surgical/non-surgical limit applies. This is why comparison of benefits is critical.
Most New Zealanders overpay on health insurance every year simply because they don't compare prices or benefits.

Non-Pharmac Drug Cover Benefits
Pharmac is the government agency that decides which medicines are subsidised in New Zealand. Drugs not on the Pharmac schedule - "non-Pharmac drugs" - must be paid for privately. Many cutting-edge cancer treatments, biological medicines, and specialty drugs fall into this category. A single course of non-Pharmac cancer treatment can cost $50,000-$150,000 as outlined in this historical Stuff.co.nz article.
This is one of the most important areas of your health insurance policy to understand - and one of the easiest to get wrong.
What You Need to Know
Optional Add-Ons Matter
Our View:
This is one of the most important areas of your health insurance policy to understand - and one of the easiest to get wrong.
What You Need to Know
- All five insurers we reviewed offer some level of non-Pharmac cancer drug cover as standard, but the limits vary. Most insurers cap this benefit at $10,000, while one offers up to $20,000. These limits may sound significant, but when a single course of treatment can cost $50,000-$150,000, even the highest standard benefit covers only a fraction of potential costs.
- Non-cancer non-Pharmac drugs - specialty medications for conditions other than cancer - are far less commonly covered. Some insurers include limited cover as standard, others do not cover non-cancer non-Pharmac drugs at all. If you rely on or may need specialty medications not funded by Pharmac, this is a gap worth investigating before you buy.
Optional Add-Ons Matter
- Several insurers offer optional add-ons that increase your non-Pharmac drug cover for an additional premium. These add-ons vary by insurer - some cover cancer drugs only, while others extend to non-cancer medications. The cost of adding non-Pharmac cover depends on your age and the level of cover selected.
- Whether the add-on is worth it depends on your personal risk profile, family health history, and budget. If you have a family history of cancer or a condition requiring specialty medication, the additional premium could be one of the most valuable parts of your policy.
Our View:
- Non-Pharmac drug cover is complex and the differences between insurers are significant. Policy wordings change, add-on options differ, and what is covered under one insurer's standard policy may require an add-on or may not be available at all with another.
- We strongly suggest discussing non-Pharmac cover with a qualified insurance adviser who can review the latest policy wordings and match cover to your specific health needs. Getting this wrong could leave you tens of thousands of dollars out of pocket at exactly the time you can least afford it.
- If you are comparing policies yourself, ask each insurer directly - what is my non-Pharmac cancer drug limit, what is my non-cancer non-Pharmac limit, and is there an add-on available to increase it? Get the answers in writing.

Mental Health Benefits
Mental health coverage is one of the most variable categories across insurers. Some offer meaningful cover while others exclude mental health entirely. Given the prevalence of mental health conditions and the cost of private psychiatric care, this is an important category to understand.
| Benefit | Southern Cross | AIA | nib | Partners Life | Unimed |
|---|---|---|---|---|---|
| Psychiatric Hospitalisation | $3,500 | Not covered | Not covered | Not covered | $5,000 |
| Psychiatrist/Psychologist Consultations | $750 | Covered | $800 for cardiac/cancer-related only | $2,500 | Not covered |
Psychiatric hospitalisation covers inpatient treatment for acute mental health conditions. Unimed leads with $5,000 cover. Southern Cross offers $3,500. AIA, nib, and Partners Life do not offer psychiatric hospitalisation cover. Given that a single inpatient stay can cost $10,000-$30,000, even the highest limit provides only partial protection.
Outpatient consultations with psychiatrists and psychologists vary significantly. Partners Life leads with $2,500. Southern Cross offers $750. AIA covers consultations under other benefits. nib, and Unimed do not offer outpatient mental health cover. At $200-$400 per session, even $2,500 covers only 6-12 sessions.
Important: If mental health coverage is important to you, consider Unimed for hospitalisation and/or Partners Life for outpatient consultations. Be aware that no insurer offers comprehensive mental health coverage - all limits are relatively modest compared to potential treatment costs.

Surgical Procedures Benefits
Surgical cover is the core of any health insurance policy. This covers the cost of operations, surgeon fees, anaesthetist fees, hospital stays, and related expenses. Complex surgeries can cost $50,000-$150,000 or more.
| Benefit | Southern Cross | AIA | nib | Partners Life | Unimed |
|---|---|---|---|---|---|
| Surgical Procedures | Unlimited | Unlimited | $600,000 | $600,000 | Unlimited |
| GP Minor Surgery | Not covered | $3,000 | $1,500-$5,000 | $3,000 | Unlimited |
| Skin Lesion Removal | $5,000 | Not covered | $6,000 | $5,000 | Covered |
| Oral Surgery | Covered | $5,000 | $5,000 | $5,000 | Unlimited |
Know This: Southern Cross, AIA, and Unimed offer unlimited surgical cover - meaning no cap on what they will pay for surgery in any policy year. nib and Partners Life cap surgical cover at $600,000.
For most people, $600,000 is sufficient for a single year. However, if you face multiple surgeries, complications requiring repeat procedures, or extended hospitalisation, unlimited cover provides peace of mind. The premium difference between $600,000 and unlimited cover is often modest - worth checking when you get quotes.
GP minor surgery covers small procedures performed in GP clinics rather than hospitals, such as minor skin procedures, injections, and small removals. Benefits vary:
Skin lesion removal is worth noting, given New Zealand's high skin cancer rates.

Diagnostic Testing Benefits
Diagnostic testing - MRIs, CT scans, ultrasounds, biopsies, blood tests - often occurs before surgery to determine what treatment you need. This is one of the most complex areas of health insurance because each insurer structures their diagnostic benefits differently. Some bundle diagnostics into surgical or non-surgical limits, others offer separate benefit pools, and most apply time restrictions that catch people out.
Understanding how your insurer covers diagnostics - and what restrictions apply - is critical. If your GP orders an MRI to investigate symptoms and you ultimately do not need surgery, or surgery happens outside the insurer's time window, you may need to pay out of pocket. We outline key information about each insurer below.

Understanding how your insurer covers diagnostics - and what restrictions apply - is critical. If your GP orders an MRI to investigate symptoms and you ultimately do not need surgery, or surgery happens outside the insurer's time window, you may need to pay out of pocket. We outline key information about each insurer below.
Southern Cross
- Southern Cross provides three separate diagnostic benefit pools under Wellbeing Two: $60,000 for diagnostic imaging, $5,000 for cardiac tests (which must be performed by an affiliated provider only), and $3,000 for diagnostic tests.
- Time restrictions depend on your policy tier. Wellbeing One applies a 6-month rule - tests must occur within six months either side of surgery to be covered. Wellbeing Two does not apply this restriction, meaning your diagnostic tests are covered regardless of when surgery occurs.
- If you are comparing Southern Cross quotes, confirm whether you are being quoted on Wellbeing One or Wellbeing Two - the diagnostic flexibility is meaningfully different.
AIA
- AIA does not have a standalone diagnostic benefit pool in the traditional sense. If your diagnostic imaging and tests relate to a private hospital admission, they fall under the relevant surgical, non-surgical, or cancer care benefit maximums, and a 12-month time restriction applies - tests must be performed within twelve months before or after surgery. AIA also covers diagnostics on a specified list up to a maximum of $200,000.
- As an optional add-on, AIA offers a separate Diagnostics Benefit list that pays up to $100,000. This add-on increases your premium but provides an additional pool of cover.
nib
- nib includes unlimited diagnostic investigations (from a specified list) as standard in their base cover — a genuine standout feature. Hospital-related diagnostics fall under the surgical or non-surgical benefit limit respectively.
- As an optional add-on, nib offers $3,000 for diagnostic tests and $60,000 for cardiac tests. If cardiac health is a concern, this add-on is worth considering.
Partners Life
- Partners Life offers a Major Diagnostics benefit list with a maximum of $200,000. If diagnostic testing relates to a surgical or non-surgical admission, it is covered under those respective limits, and a 12-month time restriction applies.
- Partners Life also offers an optional Tests benefit limited to $10,000 for diagnostics outside the major benefit list.
Unimed
- Unimed's diagnostic imaging benefit is an optional add-on only, with a limit of $7,500. This covers imaging such as X-rays, mammography, ultrasounds, and nuclear scanning.
- Separately, some imaging is covered under a $300,000 combined maximum, but this applies specifically to surgery-related imaging with a 6-month admission rule — tests must be performed within six months before or after surgery. If you do not require surgery, this larger pool does not apply.
- Be aware that Unimed's diagnostic structure means you could face significant out-of-pocket costs for standalone diagnostic testing if you have not opted into the imaging add-on.
Specialist Consultations by Insurer
Specialist consultations - seeing a surgeon, physician, or other medical specialist — are covered differently depending on whether the consultation relates to a private hospital admission or not. This distinction matters because most insurers bundle admission-related consultations into your surgical or non-surgical limits, while standalone consultations (where you are not admitted to hospital) may require an optional add-on or have a separate, lower cap.
Southern Cross
AIA
nib
Partners Life
Unimed
Southern Cross
- Under Wellbeing One, specialist consultations are covered up to $5,000 if they relate to a private hospital admission under surgical, non-surgical, or cancer care benefits. The 6-month rule applies. Consultations not related to a private hospital admission are not funded under Wellbeing One.
- Wellbeing Two adds $5,000 for consultations not relating to private hospital admission - a meaningful upgrade if you need specialist advice outside of a hospital pathway.
AIA
- If you have a private hospital admission, specialist consultations fall under the surgical, non-surgical, or cancer care benefit maximums, with a 12-month time restriction.
- AIA also offers an optional benefit of $10,000 for consultations not related to a private hospital admission.
nib
- nib covers specialist consultations between $3,000 and $5,000, depending on the policy tier and the type of consultation.
Partners Life
- Partners Life follows the same structure as AIA. Admission-related specialist consultations fall under the surgical, non-surgical, or cancer care benefit maximums with a 12-month time restriction.
- An optional benefit of $10,000 is available for consultations not related to a private hospital admission.
Unimed
- Admission-related specialist consultations fall under the surgical, non-surgical, or cancer care benefit maximums. A 6-month time restriction applies to specialists and some imaging.
- Unimed offers an optional benefit of $5,000 for consultations not related to a private hospital admission.
Recovery and Rehabilitation Benefits
Just as important to any treatment is the recovery. Recovery benefits cover the support you need after treatment - physiotherapy, home nursing, speech therapy, and similar services. These benefits help you get back to your normal life, but they vary significantly between insurers.
| Benefit | Southern Cross | AIA | nib | Partners Life | Unimed |
|---|---|---|---|---|---|
| Physiotherapy | $300 | $750 | $750-$1,000 | $750 | $500* |
| Dietitian | $300 | $500 | $500-$750 | $500 | $500* |
| Speech/Language Therapy | $300 | $500 | $500-$750 | $500 | $500* |
| Home Nursing | $2,800 | $5,000 | $5,000-$6,000 | $3,000/event | $5,000 |
| Ambulance | $1,000 | $1,000 | $1,000 | $1,000 | $1,000 |
*Surgery, chemotherapy, or radiation-related only
Physiotherapy limits range - at $80-$120 per session, even the highest limit covers only 8-12 sessions. Unimed only covers physio if related to surgery, chemotherapy, or radiation - not for standalone treatment.
Home nursing covers nursing care at home after hospital discharge. Most insurers offer $5,000 to $6,000. Southern Cross offers $2,800 (lowest). Partners Life structures it as $3,000 per event rather than per year.
Be aware that Unimed limits all recovery benefits (dietitian, speech therapy, physiotherapy) to surgery, chemotherapy, or radiation-related treatment only. If you need rehabilitation for any reason other than a covered condition, Unimed will not cover it.

Overseas Treatment Benefits
Overseas treatment coverage matters if you may need medical care that is unavailable in New Zealand, or if you want the option to seek treatment in Australia or elsewhere. This is separate from travel insurance - it specifically covers planned medical treatment overseas.
| Benefit | Southern Cross | AIA | nib | Partners Life | Unimed |
|---|---|---|---|---|---|
| Treatment in Australia | Not covered | 100% reasonable NZ charges | Efficient Market Price | UCR charges | Covered |
| Medical Tourism (elective overseas) | Not covered | 75-85% NZ charges | Not covered | 75% | $30,000 (loyalty) |
| Treatment Unavailable in NZ | $30,000 | $30,000 | $30,000 | $30,000-$60,000 | Not covered |
| Travel/Accommodation | Included | Included | Included | Included | Included |
Most insurers cover treatment in Australia, but not all. AIA covers 100% of reasonable New Zealand charges. nib covers at "Efficient Market Price". Partners Life covers "UCR" (Usual, Customary, Reasonable) charges. Southern Cross does not cover treatment in Australia at all.
Medical tourism - choosing to get treatment overseas when it is available in New Zealand - is rarely covered. AIA covers 75-85% of reasonable New Zealand charges. Partners Life covers 75%. Unimed offers a $30,000 loyalty benefit. Most insurers do not cover elective overseas treatment.
Treatment unavailable in New Zealand - when no facility in New Zealand can provide the treatment you need - is covered by most insurers at $30,000. Partners Life stands out with $30,000-$60,000 (the highest). Unimed does not cover this at all, which is a significant gap for rare conditions.

Loyalty and Lifestyle Benefits
If you stay with your insurer for 2-3 years, you will (usually) unlock extra benefits. Switch providers and you lose them.
| Benefit | Southern Cross | AIA | nib | Partners Life | Unimed |
|---|---|---|---|---|---|
| Weight Loss Surgery | $7,500 lifetime | $7,500 lifetime | Not covered | $10,000 | 50% up to $8,000 lifetime |
| Bilateral Breast Reduction | $15,000 | $7,500 | $7,500 | $7,500 | $7,500 |
| Post-Mastectomy Symmetry | $10,000 | $5,000 | $5,000 | $5,000 | $5,000 |
| Sterilisation | $2,500 | $2,500 | $2,500 | $2,500 | $5,000/year |
| Health Screening | Not covered | $500-$750 | Not covered | Not covered | Bowel screening kits |
Weight loss surgery is a loyalty benefit at several insurers - Partners Life pays up to $10,000, Southern Cross and AIA offer $7,500, and Unimed covers 50% to $8,000. nib doesn't cover it. You'll need to meet medical criteria to qualify.
Health screening cover is patchy. AIA pays $500-$750 (more for Vitality members), and Unimed provides bowel screening kits. Southern Cross, nib, and Partners Life don't offer screening benefits.

Support and Allowance Benefits
Support benefits help with costs beyond direct medical treatment - accommodation, travel, public hospital stays, and complications from treatment.
| Benefit | Southern Cross | AIA | nib | Partners Life | Unimed |
|---|---|---|---|---|---|
| Support Person Accommodation | $150/night, $3,000 max | $150/night, $3,000 max | $150/night, $3,000 max | $150/night, $3,000 max | $150/night, $3,000 max |
| Public Hospital Cash Grant | Not covered | $3,000 | $3,000 | $3,000 | $1,800 |
| Medical Misadventure | Not covered | $30,000 | $30,000 | $30,000 | Not covered |
Public hospital cash grant pays you a daily amount if you are treated in a public hospital instead of going private (for example, during an emergency admission). Most insurers offer $3,000/year. Unimed offers $1,800. Southern Cross does not offer this benefit.

Family and Child Features and Benefits
If you have children or are planning a family, understanding newborn addition terms, parent accommodation, and pregnancy coverage is important.
| Benefit | Southern Cross | AIA | nib | Partners Life | Unimed |
|---|---|---|---|---|---|
| Parent Accommodation Allowance | $150/night, $3,000 max | $150/night, $3,000 max | $150/night, $3,000 max | Not covered | $150/night, $3,000 max |
| Add Child Without Underwriting | 3 months | 3 months | 4 months | 6 months + first 6 months free | 1 month |
Adding newborns without underwriting allows you to add your baby to your policy without medical questions or potential exclusions - but you must act within a limited timeframe. Partners Life offers 6 months free, and you get 6 months. nib gives you 4 months. Southern Cross and AIA give you 3 months. Unimed gives you just 1 month - miss this window and your child faces full underwriting.
| Benefit | Southern Cross | AIA | nib | Partners Life | Unimed |
|---|---|---|---|---|---|
| Obstetrics/Pregnancy | Limited | $3,500/year (incl. $1,500 loyalty) | $2,000-$4,000 (high-risk only) | Limited | Limited |
| Infertility Diagnosis/Treatment | Not covered | Covered (only insurer) | Not covered | Not covered | Not covered |
Pregnancy coverage is limited across all insurers. AIA offers the most comprehensive cover at $3,500/year (including a $1,500 loyalty benefit). nib covers $2,000-$4,000 but only for high-risk pregnancies. Most other insurers offer minimal or no pregnancy cover. Note that routine maternity care and IVF remain excluded across the industry.
Infertility diagnosis and treatment is covered only by AIA. All other insurers explicitly exclude it. If fertility treatment is a priority, AIA is currently the only option.

Funeral and Death Benefits
These benefits support your family if the worst happens. They are separate from life insurance and are included as part of your health policy.
| Benefit | Southern Cross | AIA | nib | Partners Life | Unimed |
|---|---|---|---|---|---|
| Waiver of Premium on Death | Not covered | 2 years | 2 years | 3 years | 2 years |
| Funeral Support (Adult) | Not covered | Not covered | $5,000 | $10,000 | $2,400 |

Frequently Asked Questions
These questions address the most common areas of confusion about health insurance benefit limits.
What are non-Pharmac drugs and why do they matter?
Pharmac decides which medicines the government subsidises. Anything not on their list you pay for yourself - and that includes many newer cancer treatments, biologics, and specialty drugs. A single course of non-Pharmac cancer medication can run $50,000-$150,000, so a policy capping cover at $10,000 leaves a big gap.
Why do diagnostic testing time restrictions matter?
Most policies only cover diagnostic tests (MRIs, CT scans, biopsies) if they occur within 6 months before or after surgery. Real life often does not follow this neat timeline. Your GP might order tests to investigate symptoms, specialists might monitor a condition for months before deciding on treatment, or you might have tests that ultimately show you do not need surgery. In all these cases, you may need to pay for tests out of pocket.
What's the difference between "covered" and a specific dollar limit?
"Covered" means the treatment falls under another benefit - usually your surgical or non-surgical limit - rather than having its own cap. So if chemotherapy is "covered," your overall surgical limit applies. Check what that parent limit is to know your actual cover.
What is a loyalty benefit?
Extras you unlock after 2-3 years with the same insurer - things like prophylactic surgery, some overseas treatment, and health screening. Switch providers and you lose them, then have to re-qualify from scratch. It's a hidden cost of changing insurers that doesn't show up when you compare premiums.
What is prophylactic treatment, and why would I need it?
Prophylactic (preventive) treatment removes healthy tissue to prevent disease from developing. The most common example is preventive mastectomy for women with BRCA gene mutations who face high breast cancer risk - removing breast tissue before cancer develops. If you have a family history of genetic cancers, this coverage could be important.
Why does mental health cover vary so much between insurers?
Mental health treatment is ongoing, unpredictable, and expensive - hard for insurers to price. So many either exclude it or offer limited cover. Unimed goes furthest with $5,000 psychiatric hospitalisation limits, though even that only covers a fraction of potential inpatient costs. The differences between policies are significant, so check the specifics.
Can I add my newborn to my policy without medical questions?
Yes, but you must act within a limited timeframe that varies by insurer. Partners Life offers 6 months (the first 6 months are free). nib gives you 4 months. Southern Cross and AIA give you 3 months. Unimed gives you just 1 month. If you miss this window, your child faces full medical underwriting, which could result in exclusions for any conditions identified at birth or in early infancy. Put a reminder in your calendar when your baby is born.
What is medical misadventure cover?
Medical misadventure covers additional treatment needed due to complications or errors during your original treatment - for example, if a surgical wound becomes infected and requires further surgery, or if you have an adverse reaction to medication.
What does "waiver of premium on death" mean?
If the main policyholder dies, this benefit allows surviving family members (spouse, children) to continue their health cover without paying premiums for a specified period. This provides financial breathing room during a difficult time. Partners Life offers 3 years free cover. AIA, nib, and Unimed offer 2 years. Southern Cross does not offer this benefit at all.
Does health insurance cover infertility treatment?
AIA is the only insurer that covers infertility diagnosis and treatment. All other insurers explicitly exclude it. Note that IVF and assisted reproduction remain excluded industry-wide - even AIA does not cover IVF. If fertility investigation is a priority, AIA provides partial protection, but you should budget for high out-of-pocket costs regardless.
Should I choose unlimited surgical cover or is $600,000 enough?
$600,000 covers most people in most years. But multiple surgeries, complications, or extended ICU time can blow through that quickly. The gap between $600,000 and unlimited is often just $200-$400 a year - worth getting quotes for both to see the actual difference.
How do I know if my treatment will be covered?
Contact your insurer before treatment. Your GP or specialist can do this for you. Pre-approval avoids surprise bills and clarifies any limits or exclusions. Most insurers confirm within a few days. Don't assume you're covered based on general policy wording - get it in writing for your specific situation.
