New Zealand has trumped Australia as a happier country in a survey ranking the well-being of nations.
The New Economics Foundation's Happy Planet Index rated New Zealand as the world's 28th-happiest country - well above Australia's ranking of 76.
Costa Rica was rated the happiest country, ahead of Vietnam and Colombia. Bottom, in 151st place, was Botswana
The survey based its rankings on data from the Gallup World Poll, which asked people where they stood on the happiness ladder, from zero to 10. This was then compared with the life expectancy and ecological footprint of a country to determine its standing.
New Zealand and Australia had very poor ecological footprints - the measure of land needed to sustain a country's consumption.
