Women and people living on the South Island are the most likely to be stressed among New Zealanders, according to a survey.
Roy Morgan Research found that 22.1% of women had reported feeling stressed in the last year, considerably more than the 13.1% for men.
The survey indicated that 19.4% of South Islanders had felt stress, compared to 17.2% of people on the North Island.
This was a big change from Roy Morgan's 2011 survey, said the firm's general manager.
"A wide range of factors can contribute to stress, including work, finance, health and family matters," said Pip Elliott.
"In terms of how this has changed historically for the North and South Island, the biggest increase was among those who live in the South Island, increasing from 16.5% in 2011 to 19.4% in 2012," he said.
The younger generations were more likely to say they had experienced stress in the last year. Those born between the early 1980s and the early 2000s had a stress rate of 22.4% - the highest of the demographic cohorts.
Stress among the pre-baby boom generation dropped from last year's survey.
Generation X (people born between 1965 and 1980) remained fairly static, with almost one-in-five reporting experiencing stress.
