New Zealand's Sister Cities Directory
An interactive directory of all 98 formal sister city and sister province relationships across 35 New Zealand cities — with economic, education, and cultural data for each partnership.
New Zealand's International City Partnerships — In One Place
This directory brings together verified data on formal sister city and sister province relationship held by a New Zealand local authority. It covers 35 cities across all regions, 98 bilateral partnerships, and 12 partner countries — making it the most comprehensive public resource of its kind in New Zealand.
For each partnership you will find economic data (GDP per capita, household income, consumer market size, key industries and exports), education statistics (student enrolments at all levels, international student flows), cultural highlights, and a record of documented activities between the two cities.
The directory is produced and maintained by Eastern Bridge, New Zealand's leading sister city relationship management company. Data is sourced from individual council websites, Wikipedia, the World Bank, MFAT, and Global Cities New Zealand, and is updated regularly.
