A website for people looking for a bit of hanky panky on the side arrives in New Zealand this month.
Adulterers can sign up to www.ashleymadison.com for free, according to media reports.
Like any dating website, users create a profile and search for their perfect mate.
However they must buy credits to communicate with other users to arrange the affair meeting places.
Creator Noel Biderman told reporters he brought the service here to because so many Kiwis tried to sign up on the Australian site which launched last week.
"Four to five thousand people were trying to log in from New Zealand. We thought while we were (in Australia) we should grab that opportunity," he said.
The site's slogan is "Life is short, have an affair".
Biderman created the site in Canada in 2001 before expanding to the US and UK.
It has 5.7 million anonymous members.
The 38-year-old former lawyer and sports agent said he was a "happily married" father of two and would be "devastated" if his wife cheated on him.
