Forget gold digging - more money doesn't necessarily mean more happiness in a relationship, a recent survey in the UK has found.
The survey, as reported by The Telegraph, found two-thirds of the 500 participants earning more than NZ$200,000 admitted to having relationship problems at home.
In addition to the survey, the latest research from the UK's national statistics office also reported most British people were happy with only their basic wants and needs being met.
A UK scientist says there's an optimal earnings point that could make people happier in their relationships and day to day life. Behavioural science professor Paul Dolan said, as reported by The Telegraph, that salary is anywhere between NZ$80,000 and $117,000.
One unnamed man who quit his six-figure job for a lower-paid career spoke to the publication about his lifestyle change.

The UK research is backed up by a study out of Canada. A poll conducted for Global News in December by market researcher Ipsos found Canadians weren't feeling as good about romance, but were in fact feeling better about their finances.
"While many Canadians are feeling better about their financial security, it may be at the expense of their romantic life.
"The Ipsos poll found that 59 percent of Canadians rate their sex or romantic life as good. That's a three percent point decline over the last year," reports Global News, citing the poll results.
