The next census is on Tuesday, 6 March 2018 and the data from this will be used to make decisions by many different types of organisations. Government agencies use the data to help guide where new facilities are built and where resources should be spent; councils use the data for growth planning; private companies use the data to determine customer bases.
There is a lot of data gathered and if you are not sure how this could benefit your companies decision making, then head along to one of the meetings Statistics New Zealand has planned around the country.
