At the end of 1918, William Massey's government revived a pre-war immigration scheme and began advertising for immigrants in Britain. The international economic collapse in 1929 dragged New Zealand's economy down with it, though, and depression set in during the early 1930s. After 1929 the assisted immigration scheme was to all intents and purposes in abeyance, although domestic servants continued to be given assistance until 1931. Only 125 people were assisted to New Zealand after that year until the declaration of war in 1939.
The composition of the inflow from Britain and Ireland was quite different from the composition of the United Kingdom as a whole. By comparison with the distribution of population in the homelands, there were generally fewer English than might be expected and considerably more from Ireland and especially Scotland.
