Today is Census day - a nationwide headcount of everyone in New Zealand and where they are living or staying.

It’s an important five-yearly data collection event that provides a snapshot of our nation at a point in time, including providing detailed information about New Zealand’s small communities.

It helps the Government know who you are, where you are, and what resources your community needs.

Census data is used to plan infrastructure like water and roads, and services like schools and hospitals.

NZ Herald Head of Newsroom Data Chris Knox joins Nick Mills to explain its importance.
