If your partner supports National, has a PC, drinks Coke, eats meat, has a tattoo, smokes and is a Christian, be warned - they could be a cheater.
Figures collected from the infidelity website AshleyMadison.com have profiled the New Zealanders most likely to sign up.
They are most likely to be a Christian (58.7 per cent), support the National Party (33.3 per cent) and have had two extramarital affairs (13.6 per cent).
Cheaters are also more likely to own a PC over a Mac (79 per cent), drink Coke rather than Pepsi (84 per cent), eat meat (95.3 per cent) and be three times more likely than the national average to have a tattoo and twice as likely to smoke.
A promiscuous 10 per cent of respondents admitted having six to 10 affairs.
The website also identified the "cheating hotspots" in New Zealand, charting where its 54,000 members live to create a "cheaters per capita" table.
The distribution was fairly evenly spread - the website said 1.26 per cent of Christchurch people were signed up, making it the top hotspot , while Auckland and Hamilton were second with 1.23 per cent of their populations on the site.
Wellington (1.22 per cent) and Dunedin (1.2 per cent) rounded out the top five.
As well as coming second for the largest number of members, the City of Sails was also found to have the highest proportion of females hooking up outside their marriage.
Thirty-six per cent of Auckland members were women, 7 per cent higher than the national average of 29 per cent.
The founder of AshleyMadison.com, Noel Biderman, said the study demonstrated that "infidelity is part of human nature".
"It transcends geography, age, political disposition and religion."
The site, which uses the slogan "Life is short, have an affair", was launched in New Zealand in April 2010.
It started in Mr Biderman's native Canada in 2001 before expanding to the United States and Britain. Membership of the website doubled last year.
