The MOSAIC Type allocated to each of New Zealand's 1.4 million residential households is based on a number of statistical measures originating from exclusively New Zealand data sources available at different geographic levels:

• Housing Valuations Data provided by Quotable Value NZ including property type, size, value and owner status for 1.4 million NZ households.

• 2001 NZ Census Information including age, income, occupation, education, household, car ownership and so on for all 38,365 Census Meshblocks.

• Market Research on attitudes, media, activities and shopping habits provided by Roy Morgan Research from Single Source Surveys.

• Motor Vehicle Data provided by Cadmus outlining what types of vehicles are popular within the clusters.

In total over 140 variables were used to build MOSAIC and further 350+ variables used to describe the segments.
