"So being insured can be the difference between managing travel hiccups and having it ruin your holiday - and finances beyond - particularly because research tells us that the public won't necessarily come to the party and pick up unexpected bills."
New Zealand has reciprocal health agreements with Australia and the UK so travellers could access some health services in those countries, but White said it was a different story in other countries.
Last year alone Southern Cross paid out for 10 medical claims that exceeded $200,000 each, including a half a million dollar case of encephalitis in Africa.
White said there were few places overseas where Kiwis could access free healthcare and although most New Zealanders understood this, unexpected bills for illness or injury could be difficult to front up for.
"While we all hope we'll escape our holiday without falling sick or suffering an injury, considering potential risks and preparing yourself for the unexpected will always pay off," White said.
"Especially when we know most people back home are probably not going to fork out for your bills."
