If you have a pre-existing medical condition, finding the right travel insurance is essential but can feel complicated. Disclosure is mandatory, premiums may be higher, and some conditions may be excluded. However, many NZ travellers with conditions like diabetes, heart disease, and cancer history successfully obtain comprehensive cover. Compare your options below.
Southern Cross offers an online medical screening process that allows many pre-existing conditions to be assessed and covered. Their comprehensive plans provide unlimited medical cover, which is particularly important for travellers with existing health conditions - click below to get a quote.
A pre-existing medical condition is any illness, injury, or medical condition that you have been diagnosed with, treated for, or experienced symptoms of before purchasing your travel insurance policy. This includes conditions you are currently being treated for, conditions that are stable and well-managed, and conditions you have had in the past - even if they are currently in remission.
Disclosure is not optional. Every NZ travel insurance provider requires you to declare all pre-existing medical conditions when purchasing a policy. This typically involves completing an online medical screening questionnaire that asks about your conditions, medications, treatments, and medical history. Based on your answers, the provider will either cover the condition at standard premium, cover it with an additional premium loading, exclude the specific condition from cover, or decline to offer you a policy.
The consequences of non-disclosure are severe. If you fail to declare a pre-existing condition and subsequently make a claim related to that condition - or in some cases any claim at all - your insurer can decline the claim and void the entire policy. Insurers routinely request medical records from your NZ GP when assessing claims, so undisclosed conditions are regularly discovered. The Insurance & Financial Services Ombudsman (IFSO) handles disputes, but non-disclosure cases are difficult to win.
The good news is that many common conditions can be covered. Controlled high blood pressure, well-managed type 2 diabetes, stable heart conditions, mild asthma, high cholesterol on medication, and many other conditions are routinely covered by NZ travel insurance providers - often with a modest additional premium or sometimes at no extra charge. The key factors are stability (how long the condition has been stable), severity, and treatment compliance. See our full NZ travel insurance comparison for provider details.
Understanding the risks and common pitfalls helps you avoid claim disputes and find appropriate cover.
| Risk | Level | Details | Insurance Impact |
|---|---|---|---|
| Non-disclosure and Claim Denial | High | Failing to disclose a pre-existing condition is the number one reason travel insurance claims are declined in New Zealand. Insurers have the legal right to request your full medical records from your NZ GP when assessing a claim. If they discover an undisclosed condition - even one unrelated to the claim in some policy wordings - the claim can be denied and the policy voided. The IFSO reports that non-disclosure is the most common issue in travel insurance complaints. | Always declare every condition, medication, and medical event - no matter how minor you consider it. If in doubt about whether something counts as pre-existing, declare it anyway. It is far better to pay a higher premium or accept a specific exclusion than to have an entire claim denied. |
| Condition Flare-up Overseas | High | Pre-existing conditions can worsen or flare up while travelling due to changes in routine, diet, climate, altitude, time zones, and stress. Diabetics may struggle with blood sugar management across time zones. Heart conditions can be exacerbated by altitude or heat. Respiratory conditions can worsen in polluted cities or at high altitude. Mental health conditions can be triggered by travel stress. | If your pre-existing condition is declared and covered, treatment for a flare-up is typically covered under the medical expenses section. If the condition is excluded, treatment related to that condition is not covered. Ensure you understand exactly what is and is not covered before travelling. |
| Medication Issues While Travelling | Moderate | Running out of medication, lost medication, customs confiscation, and difficulty obtaining prescriptions overseas are all risks for travellers on regular medication. Some countries do not stock the same medications available in NZ, and obtaining a prescription overseas can be complicated and expensive. Certain medications (particularly controlled substances) are restricted or illegal in some countries. | Travel insurance typically covers emergency replacement of lost or stolen medication. However, routine prescription refills and medication you simply forgot to pack are not covered. Check import restrictions for your medications at your destination using the SafeTravel website. |
| Trip Cancellation Due to Health Changes | Moderate | A change in your condition before departure - a new diagnosis, worsening symptoms, or a medical event - may force you to cancel your trip. Whether this cancellation is covered depends on whether the condition was declared and covered, and whether the policy's cancellation triggers include changes to pre-existing conditions. | Check the cancellation section of your policy carefully. Some policies cover cancellation due to a worsening of a declared and covered pre-existing condition. Others only cover cancellation for new, unrelated medical events. This distinction is critical if your condition is unstable or has a history of fluctuation. |
| Multiple Conditions Compounding Costs | Moderate | Many Kiwi travellers - particularly older travellers - have multiple pre-existing conditions. Each condition increases the premium loading and the complexity of the medical screening. The interaction between conditions (for example, diabetes and heart disease) can further increase risk assessments. | Be prepared for higher premiums if you have multiple conditions. Some providers assess each condition individually, while others take a holistic view. If one provider's premium is prohibitively high, try another - assessment methodologies differ. Consider whether the premium is worth the cover by comparing it against the potential medical costs overseas. |

Pre-existing conditions are a major premium factor, but the impact depends on several variables.
The specific condition and its severity are the primary factors. Controlled high blood pressure on a single medication may add little to your premium. A recent heart bypass or active cancer treatment could double it or more. Conditions affecting the heart, brain, and lungs typically attract the highest loadings.
How long your condition has been stable significantly affects the screening outcome. A condition stable for 12+ months with no medication changes is viewed more favourably than one diagnosed 3 months ago. Longer stability periods generally result in lower premium loadings.
Multiple pre-existing conditions compound the premium loading. Each additional condition is assessed individually, and the combined loading can be substantial. The interaction between conditions (e.g. diabetes plus cardiovascular disease) may increase the assessment further.
Your destination amplifies the impact of pre-existing conditions on your premium. Countries with very high medical costs (USA, Canada, Japan) result in higher loadings because the potential claim cost is greater. A heart-related claim in the USA could cost US$200,000+.
Age and pre-existing conditions interact to increase premiums. A 70-year-old with diabetes pays more than a 40-year-old with the same condition because the age-related risk compounds with the condition risk.
Providers look favourably on conditions that are well-managed with consistent treatment. Regular GP visits, medication compliance, and follow-up tests demonstrate responsible management. Conditions where treatment has lapsed or been inconsistent are viewed as higher risk.
How NZ travel insurance providers typically handle the most common pre-existing conditions. Individual outcomes vary by provider.
Includes high blood pressure, angina, previous heart attack, heart surgery, atrial fibrillation, and other cardiovascular conditions.
One of the most common pre-existing conditions among NZ travellers. Management and complications determine cover outcomes.
Cancer cover depends heavily on the type, stage, treatment timeline, and current status.
Includes depression, anxiety, bipolar disorder, and other mental health diagnoses. These conditions are increasingly recognised by travel insurers.
Practical guidance to help you navigate the medical screening process and find appropriate cover.
Declare every condition, medication, surgery, and medical investigation - no matter how minor you consider it. This includes conditions that are well-managed, conditions from years ago, and conditions you no longer take medication for. Controlled high blood pressure, a previous knee surgery, and mild asthma all count. If in doubt, declare it. An honest declaration that results in a higher premium is always better than a declined claim.
Medical screening outcomes vary significantly between providers. A condition declined by one provider may be covered by another with a modest loading. Complete the online screening with at least three providers before accepting an exclusion or a premium you consider too high. Provider screening methodologies are proprietary, so outcomes genuinely differ.
Before starting the screening process, gather your current medication list, recent test results (such as HbA1c for diabetes or blood pressure readings), and a summary of your medical history. Having this information at hand makes the screening process faster and more accurate. Your GP can provide a printed summary of your medical records.
If a condition is excluded from your policy, any claim arising from or related to that condition will not be covered. However, you are still covered for all other insured events - unrelated medical emergencies, trip cancellation, luggage, and personal liability. An exclusion does not mean you have no cover; it means you have no cover for that specific condition.
Ask your GP for a letter summarising your conditions, medications (including generic names and dosages), and treatment history. This letter serves multiple purposes: it helps overseas doctors treat you appropriately in an emergency, it helps customs officials understand your medications, and it supports your insurance claim documentation.
If your health changes between purchasing your policy and travelling - a new diagnosis, medication change, or hospitalisation - contact your insurer before you depart. Changes may affect your cover, and failing to notify your insurer of material health changes can void claims. This is particularly important for annual multi-trip policies where your health may change during the 12-month policy period.
