New Zealand Health Insurance Complaints Rose 91%: What to Check Before Comparing Policies

Health insurance complaints to New Zealand's Insurance and Financial Services Ombudsman Scheme (IFSO) rose 91 percent in the year to June, making health cover the largest category of disputes the scheme investigated for the first time, ahead of house and motor vehicle insurance. Ombudsman Karen Stevens links the increase to household financial pressure, problems in the public health system, and insurers tightening claim practices, including wider use of clauses that cap what they pay at what they consider 'reasonable' and a reduced willingness to make ex gratia payments. Most disputes are not about whether someone has cover at all, but about what the fine print actually covers. IFSO cannot force an insurer to pay, and Stevens says there is no remedy for people caught between a surgeon's charge and what their insurer will pay. The practical response is to read exclusions, waiting periods and benefit limits before comparing policies, and to get answers about cover in writing.

What the IFSO figures actually show

• Health insurance disputes rose 91 percent in the year to June 2026 and became the single largest category of disputes investigated by IFSO for the first time, overtaking house and motor vehicle insurance, which had historically dominated the complaint tables.
• The scheme completed a record 833 dispute investigations over the year, up 46 percent, and handled 3,977 cases in total including 2,602 complaints.
• More than 92 percent of the disputes accepted were insurance-related, consumers received more than $1.39 million in payments through the scheme, and disputes took an average of 46 days to investigate and close.
• Completed disputes have roughly tripled from 285 in 2022 to 833 this year; health, life and disability cover made up 21 percent of disputes in 2023/24 and 29 percent in 2024/25, before health alone took the top spot.
• Around 1.45 million New Zealanders, or 37 percent of the population, hold health cover, many of them through a workplace scheme.
• Travel insurance was the other large mover, with disputes over travel cover rising 32 percent over the year.

Two features of these numbers matter more than the headline percentage. First, the scale of the base: complaints are arriving at a scheme that is already handling record volumes, so a 91 percent move in one product line shifts the whole complaint profile. Second, the cause is different from past spikes, which tended to follow floods, storms and earthquakes, when thousands of home and car claims hit insurers at once.

Why the ombudsman says complaints are rising

Stevens told RNZ the jump came from people being under financial pressure and from issues with the public health system, and she said health insurance has tightened up in terms of what it used to be. She singled out ex gratia or goodwill payments: complaints that used to be resolved that way are less likely to be now, because from the insurer's perspective paying outside the terms and conditions of the policy affects all of its customers.

On the public system side, the New Zealand Treasury's Pre-election Economic and Fiscal Update 2026 records significant operating deficits at Health New Zealand and describes health sector infrastructure as being in poor condition. Regulators are watching the same ground: the FMA's second annual Financial Conduct Report, released in July 2026, named product design, complaints data and fraud detection as focus areas.

The pattern is not confined to one scheme. Financial Services Complaints Limited ombudsman Susan Taylor described the sharpest increase in complaints in 15 years, citing economic stress, debt and the growing use of AI to lodge complaints. FSCL is a separate dispute scheme covering many lenders, KiwiSaver providers and some insurers.

The fine print that decides most claims

Stevens put the disputes in plain terms: many of them involved disagreements about policy exclusions, benefit eligibility, limits, or changes to policy terms. Reporting on the same results describes the fights as being about what the fine print covered rather than whether someone was insured at all.

Readers comparing policies should check these areas first:

• Pre-existing conditions and waiting periods. Insurer guidance differs, and waiting periods for pre-existing conditions are usually longer than for other claims. In nib's published guide to its Standard Hospital and Premium Hospital policies, no claims directly or indirectly relating to a pre-existing condition are paid in the first three years following the join date; after three years of continuous cover, eligible pre-existing conditions may be covered, while some are never covered. nib also advises disclosing conditions you have previously had, even after a doctor has given the all-clear.
• Terms that sit outside the comparison sheet. Policies may include stand-down periods, exclusions, terms and conditions, and premium loadings that are not listed in summary material, and optional add-on benefits come at an extra cost.
• Annual benefit ceilings. Plans have differing maximum claim amounts per policy year, and higher limits can matter for conditions such as cancer while being less relevant for other procedures.
• What happens when you switch. If you move to a different insurer or plan and have pre-existing conditions, they may not be covered, or may be limited, under the new plan.

Reading is the weak link. Stevens said most people do not read their policies, that there is a lot of fine print even though it is better than it used to be, and that people take out a policy and assume they are covered. Her warning is that a policy is a legal contract, and if it does not cover something you assumed it would, nothing can be done retrospectively to make that cover materialise.

'Reasonable cost' and the surgeon-insurer gap

Part of the rise in health disputes came from insurers using clauses that allowed them to limit the amount they spend on a claim to what they deem to be 'reasonable'. Stevens said there was fresh debate on what the word 'reasonable' meant and how it was interpreted, and she acknowledged that some surgery costs were eye-watering and had gone up considerably in recent years.

The consequence shows up as a gap complaint. Stevens said there was a growing number of complaints over people having to pay the difference between what their surgeons charged and what their insurance was willing to pay, and that this was a real worry because the IFSO Scheme has no ability to make insurers pay and no remedy for consumers stuck between a surgeon's costs and what the insurer will pay.

The legal frame sits alongside this. The Contracts of Insurance Act 2024 requires a consumer to take reasonable care not to make a misrepresentation to the insurer before a consumer insurance contract is entered into or varied, and requires the insurer, before the contract is entered into or varied, to take reasonable steps to ensure the policyholder is clearly informed of specified matters. It is also an implied term of every contract of insurance that the insurer must pay any sums due on a claim within a reasonable time.

Practically, this means the useful questions before treatment are written ones: what the surgeon will charge, what the insurer will accept as reasonable for that procedure, and what the policy wording says about the difference. None of that changes the contract, but it moves the surprise from after the claim to before it.

What IFSO can and cannot do

The IFSO Scheme has provided a free and independent service since 1995 and resolves complaints about insurance and financial services, with Participants including insurers, superannuation and KiwiSaver providers, credit providers, finance companies and financial advice providers.

The process has a sequence:

• IFSO first checks whether you have told your financial services provider about the complaint, because the provider must be given a chance to resolve it.
• If the complaint has not been through the provider's internal complaints process, IFSO will usually refer it back; in about 90 percent of cases the provider reaches an acceptable outcome without a formal investigation.
• If the provider has considered the complaint and cannot resolve it, it will usually give you a letter of deadlock and refer you to IFSO, and you must contact IFSO within three months of receiving that letter.
• IFSO can only investigate providers that belong to the scheme, and only if the complaint is made by a customer of that provider or someone acting on their behalf.

The limits are explicit. Stevens said the scheme cannot make insurers pay, and that there is no remedy for consumers caught between a surgeon's costs and what their insurer is willing to pay. A complaint can test whether an insurer applied its own policy correctly; it cannot rewrite what the policy covers.

A checklist before you compare or renew

• Read the policy wording and make sure you understand at least the basics of what you are and are not getting.
• Ask specifically about exclusions, benefit limits and any letters about changed terms, and get the answer in writing.
• Treat pre-existing conditions and waiting periods as the first thing to verify, not the last, and disclose past conditions when asked.
• If you are switching, check what happens to conditions you already have before you cancel the old cover.
• Use an adviser for the complicated products. Stevens said financial advisers are the best people to advise on trauma cover, income protection and disability cover, because they are complicated products that you often need help walking through.
• Visitors who are not eligible for publicly funded health services should note that the New Zealand Government strongly advises holding comprehensive health insurance.

Questions readers ask

What exactly did IFSO report about health insurance complaints?

Health disputes rose 91 percent in the year to June 2026 and became the largest category of disputes investigated by IFSO for the first time, overtaking house and motor vehicle insurance. The scheme completed a record 833 investigations, up 46 percent, handled 3,977 cases including 2,602 complaints, and paid consumers more than $1.39 million.

Are the complaints about being denied cover altogether?

Mostly not. Stevens said many disputes involved disagreements about policy exclusions, benefit eligibility, limits, or changes to policy terms, and reporting on the same results describes the disputes as being about what the fine print covered rather than whether someone was insured at all.

What does 'reasonable' mean, and why does it matter to a claim?

It matters because insurers are using clauses that let them limit what they spend on a claim to what they deem reasonable, and Stevens said there is fresh debate about how that word is interpreted. Separately, the Contracts of Insurance Act 2024 makes it an implied term that an insurer must pay sums due on a claim within a reasonable time.

How long do I have to bring a complaint to IFSO?

You must raise it with your provider first, and only after the provider has considered it without resolving it will you usually get a deadlock letter and a referral to IFSO; you must then contact IFSO within three months of receiving that letter.

Can IFSO make my insurer pay, or cover the gap with my surgeon's bill?

No. Stevens said there is no ability for the IFSO Scheme to make insurers pay and no remedy for consumers stuck between a surgeon's costs and what the insurer will pay. Her advice is to read the policy, understand at least the basics of what is covered, and use an adviser for complex products such as trauma cover, income protection and disability cover.

How these figures were compiled

The core event and the ombudsman's quotes come from RNZ, published 29 September 2026. Volume and dispute-mix figures are drawn from B2B News, 24 September 2026, and Newswire, 24 September 2026, both reporting the IFSO Scheme's results for the year to June 2026. The complaints process, eligibility and three-month deadlock time limit come from the IFSO Scheme's published frequently asked questions, dated 10 August 2022, used here as background on how the scheme operates. Legal obligations are cited from the Contracts of Insurance Act 2024 on New Zealand Legislation.

One boundary is worth restating: these are New Zealand figures from a New Zealand dispute scheme. They should not be read as a global trend, and the exclusions, waiting periods and benefit limits that matter are the ones written into an individual policy document.
