Regional gross domestic product (regional GDP) is a geographic breakdown of national-level GDP, which is New Zealand's official measure of economic activity.

Regional GDP is presented in current (nominal) prices, and measures the value of production in the prices prevailing at the time (inflation is not removed). The series is consistent with published national accounts industry and total GDP.

Regional GDP provides coherent statistics about the economic activity of regions, using a well-recognised macroeconomic concept. The release is in response to current interest in regional economies, reflected in regional GDP being added to the list of Tier 1 official statistics.

It supports Stats NZ’s objective of providing the information New Zealand needs to grow and prosper.
