AbstractA ministerial system of government has been developed in the tiny micro state of Niue, and in this article the pattern of ministerialization is compared with a typology derived from a study of the ministerial systems in other countries with ministries and ministerial departments. In Niue while the foundations of responsible government were being laid, and functions and powers transferred to an elected executive committee, no corresponding moves were made to reorganize established public service departments and there is, therefore, a mismatch between ministers and departments. Niue like New Zealand has a form of ministerialization that initially appears to conform to the least developed mode in the typology. Niue, however, has a unique arrangement in having a Secretary to Government who is the head of the public service and chief administrative officer with control over all departments, and with a right to attend Cabinet meetings and speak on any matter. Niue, as a consequence, has a ministerial system which overall does not conform with the typology and has interest as an attempt to develop a form appropriate to a micro state.
