New Zealand cultures today

The changing nature of our populations is one reason that developing competence in working with cultural diversity is so important. In 2006:

In terms of ethnicity, Pakeha (New Zealanders of European descent) have dropped from being over 90% of the population to just over 60%, with Māori, Pasifika and Asian peoples representing increasing proportions.
There has been a similar drop amongst those identifying as ‘Christian’, with a dramatic increase in those not giving a religious affiliation.
While the majority of New Zealanders were born here, the diversity of other places has increased… those born overseas have lived here for fewer years.
During the same period, the population generally has been steadily aging, which is also reflected in the workforce.
The proportion of women in the workforce has been steadily increasing since the 1950s.
All of these factors contribute to diversity in the workplace.
