Stuff has this great article by Nile Bijoux about people being willing to lie to their insurer. Those are general insurers, but it seems a stretch to believe that the same people happy to lie on their car insurance application would suddenly become gravely honest when filling in a life application. Perhaps people don't really think of lying to their insurer as a big deal - so many do it. This is borne out in other markets too - in the UK it is estimated that it adds the equivalent of about $60 a year to every insurance policy. If that margin were applied to the 2.5 million life, trauma, IP, and TPD, policies in New Zealand it would mean about $150 million in fraud costs each year.
