Health (Medical) Insurance FAQ

Health insurance in New Zealand covers the cost of private medical treatment, including specialist consultations, surgery, diagnostics, and cancer care, allowing you to skip public hospital waiting lists and access treatment you might not otherwise have access to.

New Zealand has a publicly funded health system that provides free emergency care and essential hospital treatment. However, elective procedures can involve waiting lists of 6–18 months, and specialist appointments through the public system can take months. Health insurance sits alongside the public system, it doesn't replace it, giving you the option to go private when waiting isn't something you can afford to do.

Approximately 30% of New Zealanders hold private health insurance. Southern Cross is the largest provider with around 60% market share, followed by nib, AIA, Partners Life, Accuro, and UniMed. Policies range from basic surgical cover to comprehensive plans including specialists, diagnostics, cancer treatment, and optional add-ons like GP visits and dental.

If you want faster access to treatment, more choice over your specialist and hospital, and the peace of mind that comes with knowing you can go private when needed, health insurance is worth considering. Elan can compare health insurance options from NZ's leading providers at no cost to you.

Health insurance in NZ works by covering the cost of eligible private medical treatment. You pay a monthly premium to maintain your policy. When you need medical treatment, you seek prior approval from your insurer (where possible), receive treatment at a private hospital or clinic, and the insurer pays the provider directly, minus any excess you've chosen to pay. Some health insurers will reimburse you instead of paying the provider directly.

The process in practice:

1. A health issue arises requiring treatment (e.g. you need surgery or a specialist consultation)

2. Your GP refers you to a specialist or confirms the treatment needed

3. You contact your insurer for prior approval before the procedure (Elan can assist with this)

4. Treatment is provided at a private facility

5. Your insurer pays the provider directly or reimburses you (minus your chosen excess)

Health insurance in NZ covers elective and non-emergency treatment, it's not designed for emergencies (public hospitals handle those for free). It also works alongside ACC: if your treatment is injury-related, ACC pays first and health insurance can top up any shortfall.

Unlike income protection (which replaces lost income), health insurance specifically funds the medical treatment itself. Elan can help you understand which NZ providers offer the best fit for your specific healthcare needs and budget.

Health insurance in New Zealand typically costs between $50 and $300 per month for an adult, depending on your age, the level of cover, your chosen excess, and the provider. Premiums increase with age and as healthcare costs rise.

As a rough guide:

- A healthy 30-year-old on a mid-tier plan might pay $60–$100/month

- A 50-year-old on the same plan might pay $150–$250/month

- Adding optional benefits (GP visits, dental, specialists and tests) increases the premium

One important factor: NZ health insurance premiums have been increasing by 10–15% per year recently due to elevated medical inflation post covid. It is believed that medical inflation will likely return to a lower level from 2026 onwards, however this is not guaranteed. It is therefore important to account for this in your selection of insurer and future options.

Your excess also affects cost: choosing a higher excess (e.g. $500 per claim rather than $0) lowers your annual premium significantly. If you're healthy and rarely need treatment, a higher excess policy can deliver good value.

Elan's advice is free, and they can compare health insurance from Southern Cross, nib, AIA, Partners Life, and others to find the right balance of cover and cost for your situation.

Yes — ACC and health insurance cover completely different things and are not alternatives to each other. ACC only covers treatment costs arising from accidents and injuries. It does not cover illness of any kind, including cancer, heart disease, diabetes, or any other medical condition.

If you need surgery, specialist consultations, or diagnostics for a health condition (rather than an injury), ACC provides nothing. This is where health insurance fills the gap: it covers private treatment for illnesses, regardless of whether an accident was involved.

Even for injury-related treatment, ACC doesn't always fully fund the cost of private care. Health insurance can top up the ACC payment to cover any shortfall, allowing you to receive private treatment rather than waiting in the public system.

The combination of ACC and a good health insurance policy gives you the most comprehensive coverage: ACC handles accident-related treatment, while health insurance ensures you can access private care for any illness-related condition without waiting for the public system.

If you're not sure what ACC actually covers in your situation, the Elan team can walk you through the gap between ACC and health insurance clearly.

Health insurance in New Zealand typically covers private treatment for medical conditions that aren't caused by accident (which is ACC's territory). Standard coverage across most NZ policies includes:

Core cover (included in most plans):

- Surgical procedures (elective and non-emergency)

- Cancer treatment (chemotherapy, radiotherapy, surgery)

- Specialist consultations (related to a surgical claim)

- Diagnostic tests and scans (related to a surgical claim)

- Private hospital accommodation and theatre fees

Optional add-ons (available with most providers):

- Specialists and tests (independent of a surgical claim)

- Non-PHARMAC funded coverage (increasingly important)

- Dental and optical

What health insurance does not cover: GP visits (unless added), day-to-day dental (unless added), cosmetic surgery, fertility treatment, pregnancy (except complications), overseas treatment in most cases, and ACC-covered injuries.

The specifics vary meaningfully between providers, Southern Cross, nib, AIA, Partners Life and others all structure their plans differently. Elan can compare plan details side by side to make sure your policy covers what matters most to you.

Understanding what's excluded from health insurance in NZ is as important as knowing what's included. Standard exclusions across most policies include:

Not covered by default:

- GP visits (available as an optional add-on with some providers)

- Day-to-day dental costs like fillings or check-ups (oral surgery is usually covered)

- Cosmetic surgery or procedures

- Fertility treatment (IVF, IUI, and related investigations)

- Pregnancy and childbirth (minor complications may be covered; routine maternity is not)

- Overseas medical treatment (NZ policies generally cover NZ treatment only)

- Emergency treatment (handled free by the public system)

- ACC-covered injuries (ACC pays for accident-related treatment)

Pre-existing conditions:

Pre-existing health issues are typically excluded from cover. These exclusions are assessed individually at application and disclosed to you before your policy starts. If you non-disclose at application and try to claim on a pre-existing condition, it will likely be found out due to the medical reporting & notes from GP’s and Specialists. An insurer then has the ability to modify your policy terms based on this non-disclosure.

It's important to read your policy's exclusion list carefully. A lower-cost plan may have more restrictions than you expect. Elan can review policies from all major NZ providers and flag any exclusions that might matter for your specific health history.

Not as standard. GP visits are excluded from most base-level health insurance policies in New Zealand. Most NZ health insurers focus their standard cover on specialist consultations, surgery, cancer treatment, and diagnostics rather than primary care.

However, GP cover is available as an optional add-on with several NZ providers including Southern Cross (HealthEssentials plan), nib, and Accuro. Adding GP cover increases your premium, so it's worth calculating whether the additional cost is justified by how frequently you visit your GP.

A few things to note:

- If your GP visit leads to a referral for specialist treatment or surgery, those downstream costs are typically covered under your standard plan

- Some providers offer "everyday healthcare" plans that include GP, dental, and optical as core benefits, though these are more expensive than surgical-only plans

- Southern Cross's RegularCare plan specifically targets GP and everyday healthcare needs

For most healthy adults, keeping GP cover optional and choosing a higher-tier surgical and specialist plan is often better value. Elan can model both options and help you decide whether adding GP cover makes financial sense for your usage pattern.

Pre-existing conditions are generally excluded from health insurance in New Zealand. A pre-existing condition is defined as any illness, injury, or symptom you had before your policy started, whether diagnosed or not.

At application, each insurer assesses your medical history and notifies you of any exclusions that will apply to your policy before you accept. Common outcomes include:

- Standard acceptance with no exclusions (for healthy applicants)

- A specific condition excluded (e.g. back problems excluded due to prior treatment)

- A stand-down period before a condition can be claimed (typically 2–5 years of symptom-free time)

- Automatic exclusion of pre-existing conditions without individual assessment (non-disclosure basis)

Some NZ insurers now offer more flexible approaches, for example, covering pre-existing conditions after a specified symptom-free period, or reviewing exclusions after a set time. Providers differ significantly in how they handle this.

Critically: if you switch health insurers, conditions covered under your old policy may become excluded under the new one. Always maintain your existing cover until you fully understand what the new insurer will and won't cover for you.

Elan can help you navigate insurers' approaches to pre-existing conditions and identify which provider is most likely to offer fair terms for your health history.

An excess is the portion of a medical bill that you agree to pay yourself, with the insurer covering the rest. For example, if your excess is $500 and your claim is $8,000, you pay $500 and your insurer pays $7,500.

Choosing a higher excess lowers your annual premium, the insurer takes on less risk because you're absorbing the first portion of any claim. This can be a smart trade-off if you're generally healthy and unlikely to claim frequently.

Common excess options in NZ health insurance:

- $0 excess: highest premium, no out-of-pocket cost at claim time

- $250–$500 excess: popular mid-point, meaningfully lowers premium

- $1,000+ excess: lowest premium, best suited to those who want coverage for serious issues only

Important: how excess applies varies between providers. Some apply the excess per claim, others per policy year, and some apply it only to surgical or hospital claims rather than all benefits. Understanding this before you choose your excess amount is important.

Elan can compare how different NZ providers apply their excess and help you calculate whether a higher excess combined with lower premiums makes financial sense over a 3–5 year horizon.

Mental health coverage in New Zealand health insurance varies significantly between providers and plan levels. Basic surgical plans typically offer limited or no mental health benefits. More comprehensive plans may include:

- Inpatient psychiatric care (admission to a private mental health facility)

- Day patient mental health treatment

- Psychological consultations (in some plans, as part of specialists cover)

- Online mental health support tools

What health insurance generally does not cover for mental health:

- Ongoing outpatient counselling or therapy sessions as a standalone benefit

- Treatment for substance abuse or addiction

- Conditions that existed before the policy started

Mental health cover through health insurance is primarily designed for acute episodes requiring inpatient or day-patient treatment, rather than ongoing management of chronic mental health conditions.

For mental health-related income loss (unable to work due to anxiety, depression, burnout), income protection insurance is the more relevant product, as it pays a monthly benefit if you can't work, rather than funding the treatment itself.

If mental health coverage is important to you, Elan can compare which NZ providers offer the most meaningful mental health benefits and flag the specific policy definitions you should look at.

For most New Zealanders who value timely access to specialist care and private treatment, health insurance is worth it. The public health system is excellent for emergencies and essential care, but elective procedure wait times, often 6–18 months, mean that when you genuinely need treatment, speed matters.

In many cases, private healthcare can give you access to treatments that simply aren’t available in the public system, irrespective of wait time. This could be for a less serious health issue, right up to a non-PHARMAC funded cancer treatment in which strong private health insurance could be life-saving.

Health insurance is particularly valuable if:

- You have a family history of conditions requiring specialist intervention

- You're in your 40s–60s when health issues become more likely

- You have children who may need specialist care

- You want choice over your specialist and hospital

- You want access to private cancer treatment

The real value of health insurance is tested at claim time, when you or a family member needs treatment quickly and the public system's wait times are not acceptable, or in many cases the public system may refuse to even put you on the waitlist as they deem your issue ‘not serious enough’ to warrant treatment. The monthly premium buys you the option to act and have access to the best healthcare available.

Elan can walk you through the real cost-benefit of health insurance for your specific life stage and family situation.

Yes, children can be added to a family health insurance policy or insured under their own policy in New Zealand. Most insurers allow you to add children to your existing plan for an additional premium, with the children covered up to a specified maximum age (typically 21, or 25 if in full-time education).

Getting children covered early has a significant advantage: any health conditions that develop after the policy starts are covered (they're not yet pre-existing), whereas waiting until a child has developed a health issue may result in exclusions being applied.

Children's health insurance premiums are generally lower than adult premiums due to their lower risk profile. Adding one or two children to an existing adult policy is often quite affordable.

A few things to know:

- Children over age 16 often need their own application (you can still pay the premium)

- Coverage for children typically mirrors the plan you hold as the policyholder

- Some NZ providers offer family premium structures that reduce per-person cost

If you're considering whether to include your children on your health plan, Elan can model the cost and help you determine whether a family plan or individual children's policies makes better financial sense.

Yes, health insurance premiums in New Zealand increase every year, for two reasons: your age, and medical inflation.

Age-based increases: As you get older, your health risk increases and insurers adjust premiums to reflect this. Most NZ health insurers apply age-based stepped increases at regular intervals.

Medical inflation: Healthcare costs in NZ have been rising significantly, premiums increased by 10–15% per year across major providers in recent years, driven by rising specialist fees, new medical technologies, and increased demand for private care. Unfortunately, many health insurers are still losing money despite the premium increases, primarily because medical providers are charging increasing amounts. NZ’s largest health insurer Southern Cross lost $50mil NZD in 2025 alone but aims to turn this around over the coming years.

What this means in practice: a policy that costs $100/month today might cost $150/month in five years and $250/month in ten. It's worth factoring this trajectory into your long-term financial planning rather than only comparing today's premium.

Things that can help manage premium increases:

- Reviewing your excess each year (increasing it can reduce the premium)

- Reviewing optional add-ons, removing ones you don't use

- Comparing providers at renewal, though switching risks new exclusions for changed health

Elan reviews their clients' policies annually at no cost and can flag whether your current cover remains competitive, or whether adjustments would give you better value.
