In New Zealand, spouses cheating on their partners are being blackmailed in exchange for money.

According to recent statistics, 18% out of 80,000 New Zealanders who sign up for infidelity websites have been taken advantage of by their paramours. Members of more high-profile dating sites have either had their personal details hacked or threatened with public exposure.

In a news report, an expert in infidelity investigations in NZ shared a few cases where clients were blackmailed for money.

One client filed a report against a lover who asked for a total of US$245,000 in exchange for concealing their affairs from the client's wife and family.

The investigator further explained that men are more likely to be blackmailed for money as they have “bigger have bigger egos and talk about their financial situation to just about anyone.”

Despite the risks of blackmail and jeopardising marriages and relationships, science explains that there is a genetic explanation for cheating and infidelity.

Scientists found a gene that controls the production of vasopressin – a hormone formed and stored in the pituitary glands. The hormone, apart from its main benefits to the kidneys and blood vessels, is believed to affect social behaviour and sexual motivation.

Studies suggest that men who inherited this gene were more likely to be unfaithful. In contrast, men who did not carry the gene were more attached and loyal.
