Do I Still Need to Declare Cancer If I've Been Cancer-Free for Years?
This is one of the most common questions we receive — and the answer is unequivocal:
Yes. Always. No matter how long ago it was.
Whether it was 2 years ago or 20 years ago, a cancer diagnosis must be declared on every New Zealand travel insurance application. Here's why, what happens if you don't, and how it affects your premium.
The instinct behind not declaring is understandable: "My cancer was treated years ago, I've been given the all-clear, it feels irrelevant." But from an actuarial perspective, historical cancer is not irrelevant.
Even in complete remission for 10 years, certain cancers carry a statistically elevated long-term recurrence risk compared with someone who has never had cancer. Insurers use this statistical risk to price your policy accurately. If you do not disclose, you obtain a policy at an incorrect price — which constitutes non-disclosure of a material fact.
Most NZ travel insurance application forms ask questions like: - "Have you or any person to be insured ever been diagnosed with or received treatment for any of the following: cancer, tumour, growth?" - "Do you have any pre-existing medical condition, illness, or injury?"
Note "ever" — not "in the last 3 years" or "currently". Even under SCTI's 3-year lookback definition, many insurer application forms separately ask about cancer history.
Non-disclosure of a material fact gives your insurer the right to void your policy. The consequences:
If you make a cancer-related claim: The claim is declined. This was predictable — the cancer wasn't declared.
If you make a non-cancer claim: This is where non-disclosure truly hurts. If you fail to declare cancer and then make a claim for, say, a broken ankle, a dental emergency, or a trip cancellation due to a family bereavement — the insurer may still void your entire policy on the grounds that it was obtained through non-disclosure. You receive nothing.
The financial stakes: A voided policy during a serious medical event overseas can result in bills of: - NZ$5,000–$50,000 for a hospitalisation in Australia - NZ$50,000–$200,000 for a hospitalisation or evacuation from the USA or Europe - NZ$25,000–$80,000 for an air ambulance from the Pacific Islands
The additional premium from declaring historical cancer is a fraction of these potential costs.
The additional premium for historical cancer is generally modest compared with recent or active cancer, reflecting the lower ongoing risk. As rough indicators:
- Thyroid cancer, 5+ years ago, no recurrence: +10–25% on base premium
- Breast cancer Stage 2, 7 years ago, completed treatment, no recurrence: +25–50%
- Prostate cancer, 4 years ago, on active surveillance: +20–40%
- Melanoma Stage 1, 8 years ago: +20–40%
These are indicative only. The actual premium depends on cancer type, original stage, destination, trip duration, and age.
SCTI's 3-Year Lookback
Southern Cross Travel Insurance defines a pre-existing condition as any condition for which you have had symptoms, treatment, investigations, or consultations within the past 3 years. For cancer treated and discharged more than 3 years ago with no subsequent monitoring, this may mean SCTI does not classify your cancer as a pre-existing condition.
However — even if this is the case, many travellers choose to mention their cancer history when asked general health questions on the form, as these are sometimes separate from the pre-existing condition definition. When in doubt, declare.
"All Clear": What It Means (and Doesn't Mean) for Insurance
"All clear" is not a standardised medical term. When people say they've been given the all-clear, it may mean: - A clear scan result at one point in time - Being discharged from specialist follow-up (no further monitoring needed) - Reaching a specific survival milestone (e.g. 5 years post-diagnosis)
None of these circumstances remove the requirement to declare your cancer history. What they do is positively affect the insurer's risk assessment — which may result in a lower additional premium.
If your oncologist has formally discharged you from all cancer-related follow-up (meaning they consider ongoing monitoring unnecessary), mention this specifically in your application. It is a genuinely positive signal.
A Simple Rule
When in doubt, declare.
The worst outcome from declaring is a slightly higher premium. The worst outcome from not declaring is being left with a six-figure medical bill overseas, with no insurance to help. These are not comparable risks.
Declare honestly, pay the additional premium, and travel with the peace of mind that your policy is valid.
