Flash your black and silver New Zealand passport almost anywhere around the world and you'll get a positive response.
But if it's power you're after, you may want to get your hands on a passport from the land of the free.
After analysing how many countries it allows access to, investment opportunities and quality of life indicators, a study released on Monday found American passports to be the most powerful.
Created by Immigration investment consultancy firm Global Citizen Solutions, the Global Passport Index used a quantitative scoring system to rank passports across different criteria and categories.
With a total score of 96.4, the US was the world's strongest passport. It ranked fourth in the investment index, 10th in the enhanced mobility index but 23rd in the quality-of-life index.
