The Chair of the Motu Koita Assembly also holds the office of Deputy Governor of National Capital District.

The capital city of Port Moresby was established on the traditional lands of the Motu and Koitabu people in the late 1800s.

[2] In recognition of this, the Motu Koitabu Interim Assembly was established under the National Capital District Government Act 1982.

It was given powers and rights to legislate in the ten recognised Motu and Koitabu villages and exercise authority over their customary land, which lies within the Port Moresby boundaries.

[4] The objectives of the Act are: to protect and strengthen the identity of the Motu Koitabu people as the original landowners of the National Capital District; to promote equal opportunity and popular participation in government by the Motu Koitabu people; to provide for the Motu Koitabu people especially the basic human needs for water, health, education, transportation, communication, accommodation and social order through economic self-reliance; and to protect the customary land and natural resources of the Motu Koitabu people.
