Statistics New Zealand aims to ensure that official statistics provide a consistent and coherent picture of New Zealand's economy, society and environment. This allows comparisons to be readily made over time and across geographic areas, industries and other domains. Data produced from different sources and at different times can be brought together to provide a richer dataset for analysis. Data can also be used beyond the initial purpose for which it was produced.
Statistics New Zealand uses three key strategies to facilitate such data integration, both across statistics produced by Statistics New Zealand and with other official statistics:
Under the Statistics Act 1975, the Government Statistician is required to "define, lay down and promote standard concepts, procedures, definitions and classifications for use in official statistics".
