Health Insurance Claim Declined in NZ: The Four Reasons, and What to Do
A declined health claim is nearly always one of four things. Working out which one you are dealing with decides whether there is anything to argue about.
1. Pre-existing condition
The most common reason. The insurer has decided the condition existed before your cover started, or before the relevant waiting period ended.
The definitions are wider than most people expect. They generally capture conditions that existed before the policy began whether or not they had been diagnosed, and often whether or not you knew. Symptoms mentioned to a GP count. An investigation that found nothing counts.
Where there is room to argue: the date of onset. If the insurer has drawn a line from a GP note that mentioned a symptom, your specialist may be able to say plainly that the current condition is unrelated to it. A letter from the treating specialist addressing causation directly is the single most effective document in this kind of dispute.
2. Non-disclosure
You did not tell the insurer something when you applied, and they have found it in your records.
New Zealand policies carry a duty to give true, correct and complete information at application and to keep the insurer updated. Chubb's Life & Living general terms state the position plainly: the insurer can take action if it receives information that is untrue, incorrect or incomplete.
Almost all non-disclosure is accidental. People genuinely forget a consultation from six years ago.
Where there is room to argue: materiality and intent. Whether the undisclosed information would actually have changed the underwriting decision matters. An omitted consultation for something unrelated to the claim is a different case from an omitted diagnosis that goes to the heart of it.
Insurers can request your medical records as part of assessing a claim, and generally do. We cover what they can access in can insurers access your medical records.
3. A benefit limit or sub-limit
Not a decline so much as a partial payment, and the most avoidable of the four.
The claim is legitimate, the cover applies, and the policy simply does not pay that much. The usual culprits are sub-limits buried inside larger benefits, a $10,000 non-Pharmac drug allowance inside a $60,000 chemotherapy benefit, for example, or a $65,000 chemotherapy cap inside a $200,000 hospital admission benefit.
Where there is room to argue: very little, if the limit is clearly written. This is a reading problem, not a dispute. The fix is to find these numbers before treatment rather than after.
4. Provider network
The treatment was covered, but not where you had it.
Southern Cross requires chemotherapy to be performed by an Affiliated Provider contracted for chemotherapy, and requires cardiac tests to be performed by a contracted Affiliated Provider on referral from a specialist in private practice. Other insurers operate similar networks.
Where there is room to argue: whether you were told. If you sought prior approval and were directed to a provider, that correspondence matters. If a covered procedure was genuinely unavailable within the network in a reasonable timeframe, that is worth raising.
The process, in order
1. Get the decline in writing, with the clause. Ask the insurer to identify the specific policy provision it is relying on. "Pre-existing condition" is not an answer; a clause reference is.
2. Read that clause in your own policy document. Not the brochure, not the website. The document that governs your policy, from the date your cover started.
3. Get a letter from the treating specialist if the dispute is medical. Ask them to address the insurer's specific reasoning rather than describing your condition generally.
4. Use the insurer's internal complaints process. Every licensed insurer has one and it is free. Momentum Life, for example, publishes a four-step process ending in a letter of deadlock.
5. Go to the dispute scheme. Every financial service provider in New Zealand must belong to one, and they are free to consumers. The Insurance & Financial Services Ombudsman Scheme can be reached at ifso.nz or 0800 888 202. Others operate as well; your insurer's disclosure documents name the one it belongs to.
Time limits apply. Momentum's wording gives three months from a letter of deadlock to take a complaint to IFSO. Check the deadline that applies to you as soon as you receive a final decision.
What actually helps
In QuoteHub's experience the two things that change outcomes are a clause reference and a specialist letter addressing causation. Everything else, length, tone, frustration, does not.
The two things that do not help are arguing that the premium was expensive, and arguing that the decline is unfair without engaging with the wording. Neither is a ground a dispute scheme can act on.
If you used an adviser, this is what they are for. An adviser who arranged the policy can put the case to the insurer directly, and they know which arguments the assessor will accept.
