One of the amendments is to extend the term of parliament to five years from the current four.
It will also include a new definition of what constitutes the '"people of Vanuatu."
This aims to encompass indigenous and naturalised citizens and the descendants of naturalised citizens.
The changes will allow cabinet to be increased to 17 members from 13.
Another feature of the amendments would be to allow those with dual citizenship to hold public office, in certain circumstances which are in the public interest.
