New Zealand (NZ) has been used in the past as a testing ground quite a few times. In fact, it has been described as a ‘social laboratory’ due to its history of implementing progressive or experimental policies, particularly in the late 19th and 20th century. The reference to NZ is often attributed to the French political scientist and historian André Siegfried who used it in his book, Democracy in New Zealand (1914). https://www.google.co.nz/books/edition/Democracy_in_New_Zealand/tqomAAAAMAAJ?hl=en&gbpv=1&pg=PR3&printsec=frontcover
