Chris Knox is the Data Editor and Head of Data Journalism for the New Zealand Herald.
Chris Knox is a scientist turned data-journalist who investigates the stories behind the numbers, and creates interactives for Herald readers to explore them. After completing a PhD in physical chemistry and moving to California to research air pollution, Chris decided a life in the lab wasn't for him and serendipitously found a new role researching ways of bringing data to life using computers. He has spent more than 20 years making data more accessible in academia, industry, government - and now in the media. Chris's interactive map for Whenua: Our Land, Our History won the 2025 Voyager Award for Best Innovation in Digital Storytelling. In 2023, his analysis of polling place results uncovered errors in New Zealand's General Election results. Please contact Chris if you have an interesting dataset you think New Zealanders should see, or if you have seen data that just doesn't add up.
