Husbands and boyfriends, beware. Kiwi women are twice as likely as men to go snooping through their partners' mobile phones without permission.
A survey of 2144 mobile phone users by market researcher Canstar Blue found 13 per cent had secretly looked through their partners' phones. Women were twice as likely as men to do this.
People aged 18 to 29 were the main offenders, with 26 per cent of them admitting to having had a sneaky peek. Those aged 30 to 44 were not far behind, on 20 per cent.
Those aged 45 and older were the most trusting age group. Only 5 per cent of them said they had snooped on their spouses.
That was no surprise to private investigator Julia Hartley Moore, who said mobile phones were the first thing people checked if they suspected their partners were cheating.
Women tended to be more awake to the telltale signs of an affair, such as their partners looking at their phones a lot, taking them into the bathroom with them, and grabbing their phones whenever their partners went near them.
"Just as many women have affairs as men do, that's a fact, but women are far more intuitive and they use that intuition," she said.
"Guys don't use their intuition. They don't think anyone is going to follow them, they don't think their partner is going to check anything. They just don't think."
Men were also terrible at deleting incriminating evidence from their phones if they were sneaking around.
"Women are way craftier than men when it comes to having affairs. They're far more manipulative, cunning and calculated," she said. "They make sure they cover their bases, whereas guys don't. That's why guys get caught."
According to the survey, the most suspicious spouses live in Auckland and Waikato, where 16 per cent and 15 per cent respectively said they had spent time sifting through call histories and text messages.
Those living in Otago (12 per cent), Canterbury (11 per cent) and Wellington (10 per cent) had slightly better self-control.
The Canstar survey put a range of other mobile phone habits under the microscope.
It found 11 per cent regularly texted or talked on their phones while driving.
Again, the practice was most common among people aged 18 to 29. Nearly 1 in 5 of the people in that age group admitted to flouting the law when it came to mobile phones in cars.
