What are Tier 1 statistics?

Tier 1 statistics are the most important official statistics, essential to understand how well New Zealand is performing, as they measure the performance and progress of the economy, society and the environment.

All agencies producing Tier 1 statistics are required to comply with the principles and protocols for producers of Tier 1 Statistics.

More information, including a list of all Tier 1 statistics, is available on the Statistics New Zealand website.
