Citizenship and nationality The British Nationality and New Zealand Citizenship Act 1948 established the legal concept of New Zealand citizenship; prior to this, all people born or naturalised in New Zealand had the status of "British subject", just as those born or naturalised in the United Kingdom, or any of the other dominions. At a similar time, those in the dominions were omitted from a new status, defined in the British Nationality Act 1948, of "Citizen of the United Kingdom and Colonies", a forerunner to the modern concept of British citizenship. New Zealand passports carried the wording "British Subject" until the Citizenship Act 1977. Economic relations Britain tied itself somewhat to European trade in recent years though its membership of the European Union between 1973 when it first joined what was then known as the European Communities (the Common Market) and 2020 when it left the bloc, forcing New Zealand and Australia to seek new markets and trade with the Asia-Pacific region. New Zealand has a large influence over former British colonies in the Pacific and the British territory of Pitcairn. Up to about the 1960s, New Zealand also had extremely close economic relations with the United Kingdom, especially considering the distance at which trade took place. As an example, in 1955, Britain took 65.3 percent of New Zealand's exports, and only during the following decades did this dominant position begin to decline when the United Kingdom joined the European Economic Community (now the European Union) in 1973, with the share of exports going to Britain having fallen to only 6.2 percent in 2000. Historically, some industries, such as dairying, a major economic factor in the former colony, had even more dominant trade links, with 80–100% of all cheese and butter exports going to Britain from around 1890 to 1940. According to the New Zealand Ministry of Foreign Affairs and Trade, recent annual New Zealand exports to the United Kingdom have accounted for at least NZ$1.76 billion worth of trade, and over NZ$1 billion
