The country celebrated 36 years of independence at the weekend.
Charlot Salwai said these include reforms on motions of no confidence, in order to minimise instances of politicians crossing the floor for personal gain.
There had been calls for Mr Salwai to unite the English and French speaking MPs in the house.
Mr Salwai said of his reforms would have to be put to the people in the form of a referendum.
