Abby Hartley case causes spike in customers discussing pre-existing conditions with insurers

There's been a sharp increase in the amount of customers talking to travel insurers about pre-existing medical conditions following the death of Abby Hartley in Bali.

The 41-year-old mother of two's family wasn't covered by her travel insurance policy due to a non-declared pre-existing medical condition.

Hartley died in Bali on Sunday after her family had embarked on fundraising campaigns to cover medical expenses and bring her home.

Insurance and assistance provider Allianz Partners says since the Hartley case made headlines, they've been receiving more calls about pre-existing conditions daily than they usually get in a whole week.

Will Ashcroft of Allianz Partners said travellers are being particularly diligent about disclosing their medical history and are paying closer attention to their policy wording.

"It's extremely important to read the policy wording at the time of purchase," he said.

"All policies are different so ensure you select one that meets your needs. If you have questions, talk to your insurer."

Ashcroft said it's also important to make sure your children's pre-existing conditions are covered in your policy too, if you are travelling with them.

The Ministry of Foreign Affairs and Trade said they deal with more than 200 cases of medical emergencies or medical situations every year and and about 3000 New Zealanders are helped every year abroad.
