Te Kupenga - which means 'the fishing net' - is the second such survey, with the first in 2013.
Stats NZ spokesperson Jason Attewell said the questionnaire would be sent in the post to 11,500 people, randomly selected, who had indicated in the 2018 census they had Māori ancestry.
"We gain all sorts of insights into Māori cultural well-being.
"For example, in 2013, we learnt that 55 percent of Māori were able to speak te reo. We know that 89 percent of Māori know what their iwi is," he said.
This year's survey will include some new questions, such as the importance of te reo Māori and how well whānau are doing.
The survey closes on 26 August.
