Wellington, Sep 19 (TIWN) One third of residents in New Zealand's biggest city of Auckland are considering leaving the city in the next five years due to increasingly high cost of living, traffic congestion, and decreasing sense of safety, a new survey revealed on Monday.

According to the survey conducted by the local media outlet, Stuff, people living in Auckland are “the most unhappy region of the country”, with only two in five respondents saying they were happy, reports Xinhua news agency.  The survey covered about 5,500 New Zealanders, 33 per cent of whom were from Auckland.  “Stuff weighted the data to reflect nationally representative samples for gender, age and region,” it said.
