The legal mandate of the Tonga Statistics Department is derived from the Statistics Act 2020 which was a review of the Statistics Act 2015. The Act states that the Department:

“shall be the principal authority for the official statistics of Tonga.”(Section 3.1)

“shall collect, from people, businesses and other organisations in the Kingdom, information relating to their activities and economic and social situation, in order to compile, analyse, abstract and publish official statistics relating to the condition of commerce, people, their communities and the environment, as well as the activities, performance and impact of the Government.” (Section 3.2)

Coupled with the Cabinet decision (No.167) of February 2021 that “all surveys that have implications at the National level to be referred to the Statistics Department for clearance first, and prior to the results being released, be approved”
