The Republic of North Korea enforces strict entry and exit laws and can arrest, fine and deny entry to passport holders arriving without a visa.
Kiwis do manage to get one over the Aussies though - we don't need a visa to enter Brazil, the Australians do. However, they don't need a visa to enter South Africa.
Other countries where we edge our trans-Tasman neighbours are Turkey, Oman and Brunei - Australians need to show their visa on arrival.
There are other 22 countries sitting above New Zealand on the power index - Germany and Singapore take the top spot with 159 countries. Sweden, South Korea, United Kingdom and the United States also rank higher.
