Final notices are being sent to households that have not completed their Census forms and people can complete the Census online until June, Stats NZ says.
By 9am today, 4.4 million people had returned individual forms, however, the agency said this was not the official response rate as it would include duplicate forms and forms from overseas visitors.
The official response rate will be determined in a post-enumeration survey conducted after the Census.
The Census is an official count of people living in New Zealand and is used by the Government as well as iwi, community organisations, councils and businesses to make decisions about communities.
It’s mandatory – and was meant to be completed on Census night, March 7, by everyone except those in the areas most impacted by Cyclone Gabrielle (the Far North, Te Tairāwhiti and Hawke’s Bay), who have until June.
