The need for the New Zealand government to promote national interests during the Depression and the Second World War created a renewed appreciation of the role of the family within society.
By the late 1940s all New Zealand children had a medical examination on entering school, and were seen by a nurse at standards two and six. These examinations helped identify those who were not 'thriving' in their home environment.
As a consequence of the post-war economic boom there was increasing demand for consumer goods. The 1956 census revealed that more than half of New Zealand homes possessed washing machines, refrigerators and electric ovens.
