NZ Census 2018, explained

There's a digital-first push for this year's census with people being delivered access codes and encouraged to do the census online. It includes new questions about how much mould is in houses, whether they're warm, and how well the kitchen sink works. Around half a million people have already completed the census online, but there are concerns the elderly or those without access to computers will have trouble being counted, and stories of people in remote parts of the country being unaware it's census time. 2018 Census general manager Denise McGregor joins Susie Ferguson in the Wellington studio to explain.
