New Zealand has increased its ranking to seventh in a list assessing the reputations of 55 countries. Last year it was eighth.
Canada has beaten last year's leader Switzerland to top the 2015 "RepTrak" rankings, issued by the Reputation Institute, which has offices in many countries.
Since the survey began in 2010, Canada has ranked first all but two years and has not been placed lower than second.
The institute gathered information online for its rankings from more than 48,000 people in G8 countries.
It says this enables it to "measure the public's perception of 55 countries based on three dimensions: effective government, appealing environment, and advanced economy".
