The Norwegian capital of Oslo topped the list as the world's most expensive city, but its wages were lower than some other cities so its real wages came out fractionally below Auckland's.
In real terms, UBS's home city of Zurich in Switzerland was the richest in the world with real incomes 56.7 per cent higher than in Auckland. American cities Miami, Los Angeles and New York came next in real terms despite the plunging US dollar.
The Australian dollar, which has risen even more strongly than the kiwi against the greenback and the euro, made Sydney the world's seventh most expensive city.
In real-wages terms Sydneysiders are sixth-richest in the world, just ahead of Geneva and Dublin and much richer than once powerful capitals such as Tokyo, Berlin and London.
Melbourne tourist John Boyle, 40, interviewed outside Auckland's Sky Tower yesterday, said New Zealand's cheapness was one of the reasons he chose to holiday here rather than in Sydney or Brisbane.
"Even your fruit is cheaper," he said. "We're paying $11 or $12 a kilo for bananas."
British visitor Susan Cox, who is staying with daughter Helen Ashton in Bayswater, said foods such as fruit and vegetables were better quality than in Britain so she felt she was getting "good value for our money".
But Brazilian English language students Daniel Silva, 26, and Leonardo Fastarol, 23, said they were surprised at the cost of many items here.
"The food is the most expensive, and public transport is expensive," they said.
"But clothes and electronics are cheaper than in Brazil."
UBS New Zealand senior economist Robin Clements said international comparisons were always fraught because of the difficulty of collecting the same information in each country.
"Whether we are 24th or 23rd or 25th is open to debate, but the relative position of Auckland versus Zurich is probably pretty safe," he said.
He said the fact that the survey found real wages in Auckland higher than in Norway, France, Spain and Italy, which all have higher gross domestic products per person, reflected the fact that New Zealanders on average were spending beyond their means.
"We are still running a current account deficit and it's going to get worse," he said.
But he said the survey also showed how well Australia was doing in world terms, with the world's sixth highest gross domestic product per person last year.
