Who are we?

We are the country’s main source of national official statistics. Statistics produced by the CISO play a direct and significant role in the formation and monitoring of government policies.

During elections we also double as the Electoral Office.


We have been collecting and disseminating statistical information for more than 45 years

Our Functions

1. To collect, compile, analyse, abstract, and publish statistics on the Cook Islands economic, financial, production, environmental and social matters;

2. Make or construct statistical estimates, forecasts, projections and statistical models;

3. To define, lay down, and promote standard concepts, procedures, definitions and classifications for use in official statistics;

4. To inform other government departments on the suitability of statistical projects initiated or carried on by them


We administer the Statistics Act 2016. The Act authorises us to collect information concerning any or all of the classes of official statistics specified. 

Currently we have 13 permanent staff in the Statistics Office. Our chief executive, the Government Statistician is also the Chief Electoral Officer for the Cook Islands.
