British Dominion After
World War One, New Zealand signed the
Treaty of Versailles (1919) and joined the
League of Nations. Wellington trusted
Conservative Party governments in London, but not
Labour. When the British Labour Party took power in 1924 and 1929, the New Zealand government felt threatened by Labour's foreign policy because of its reliance upon the
League of Nations. The League was distrusted and Wellington did not expect to see the coming of a peaceful world order under League auspices. What had been the Empire's most loyal
Dominion became a dissenter as it opposed efforts the first and second British Labour governments to trust the League's framework of arbitration and collective security agreements. The governments of the
Reform and
United Parties between 1912 and 1935 followed a "realistic" foreign policy. They made national security a high priority, were sceptical of international institutions such as the League, and showed no interest on the questions of
self-determination,
democracy, and
human rights. However the opposition
Labour Party was more idealistic and proposed a liberal internationalist outlook on international affairs. From 1935 the
First Labour Government showed a limited degree of idealism in foreign policy, for example opposing the
appeasement of
Nazi Germany and
Japan.
Second World War When
World War II broke out in 1939, New Zealand whole-heartedly joined in the defence of Britain, with Prime Minister
Michael Joseph Savage declaring that "where Britain goes, we go; where Britain stands, we stand". New Zealand soldiers served in
North Africa,
Italy and the
Pacific, and airmen in England and the Pacific, throughout the war, even when New Zealand had concerns about invasion by the
Japanese.
Since 1945 During World War II the New Zealand government created a Department of External Affairs (now the
Ministry of Foreign Affairs and Trade) for the first time in 1943, taking control of foreign policy that had previously been run by the Dominions Office in London. In 1947 New Zealand ratified the 1931
Statute of Westminster with the
Statute of Westminster Adoption Act 1947, which made New Zealand fully independent of Britain. The
Fall of Singapore during World War II made New Zealand realise that she could no longer rely on Britain to defend the British Empire. New Zealand troops supported the British in the successful battle against
Communist insurrection in Malaysia and maintained an air-force fighter squadron in Singapore, and later on Cyprus, again supporting British forces. New Zealand diplomats sought an alliance with the
United States of America, and in 1951 adhered to the
ANZUS Treaty between New Zealand, Australia and the US. In return for America's guarantee of protection, New Zealand felt obliged to support America in its wars, and New Zealand committed forces to the
Korean War (1950–1953) under
United Nations Command auspices and to the
Vietnam War. By the 1970s, many New Zealanders began to feel uncomfortable with their country's support for the US, particularly in Vietnam and regarding the visits of nuclear-powered and armed
United States Armed Forces warships. The
Third Labour government (1972–1975) pulled New Zealand troops out of the Vietnam War and protested against
French nuclear testing in the Pacific, at one stage sending a warship to act as disapproving witness to the tests.
Britain's entry into the European Economic Community in 1973 forced New Zealand into a more independent role. The British move restricted New Zealand's trade access to its biggest market, and it sought new trading partners in Asia, America and the Middle East. Australia and New Zealand signed the free-trade
Closer Economic Relations agreement in 1983. The election of the
Fourth Labour Government in 1984 marked a new period of independent foreign policy.
Nuclear-powered and nuclear-armed ships were banned from
New Zealand waters, effectively removing New Zealand from the ANZUS pact. Immigration laws were liberalised, leading to a massive increase in
immigration from Asia. The
Fourth National Government (1990–1999) liberalised trade by removing most
tariffs and
import restrictions. In 2008,
Minister of Foreign Affairs Winston Peters announced what he called "a seismic change for New Zealand's foreign service", designed to remedy the country's "struggling to maintain an adequate presence on the international stage". Peters said that the Ministry would receive additional funding and increase the number of New Zealand diplomats serving abroad by 50%. ==Participation in international organisations==
