He also criticised the Constitution's amendment provisions, which says that you can't change a single line in the Constitution unless you have three-quarters of Parliament and three-quarters of registered voters in a referendum.
He says this is an impossibility as you never get three-quarters of registered voters voting ever.
He says people were effectively being prevented from changing a Constitution that was never approved through such a process.
He criticised the current electoral system, saying party leaders receive the overwhelming majority of votes while many MPs enter Parliament with very little personal support.
INSERT: Narsey on electoral system 6th July
Professor Narsey also criticised the current ballot paper, saying the system of identifying candidates by numbers creates unnecessary confusion for voters.
He recalled that during the 2014 General Election, an unknown candidate received more than 4,000 votes because his candidate number closely resembled that of the party leader.
He says the Electoral Reform Commission proposed replacing the current nationwide constituency with 25 open constituencies, using existing voter registration information and polling station boundaries.
Professor Narsey also urged the Constitution Review Commission to retain the Electoral Reform Commission's proposal for 25 reserved seats for women, saying they are necessary to improve women's representation in Parliament.
He says the Commission recommended creating 25 reserved seats for women using exactly the same constituency boundaries as the 25 open constituencies, adding that every woman in Fiji would then have a woman Member of Parliament representing her area.
He says women's organisations had been calling for stronger parliamentary representation for decades.
He says the effectiveness of the system could instead be reviewed after 15 years if women were then competing on a genuine level playing field.
Professor Narsey also proposed reducing the electoral threshold from five percent to two percent to allow smaller political parties and independent candidates a greater opportunity to enter Parliament.
Professor Narsey also proposed restoring the Senate to provide stronger checks and balances on the powers of the Government.
He says his proposed Upper House would include nominees of the Prime Minister, the Leader of the Opposition, the Great Council of Chiefs and religious organisations.
Professor Narsey urged the Commission to remove the immunity provisions contained in the 2013 Constitution, arguing they have never been approved by Parliament or through a referendum.
He distinguished them from the immunity provisions in the 1997 Constitution, saying those were debated and approved by a democratically elected Parliament.
He also questioned whether immunity should extend to serious acts committed after the 2006 coup and said no Constitution should place anyone above the law.
He warned that if you have immunity provisions in the Constitution, you are always giving the message to the people of Fiji that they can remove the Government, hold on to the Government for eight years or ten years, put their own electoral system in place, have a rigged election and then give themselves immunity.
He says that cycle would never end unless Fiji drew the line here and now.
Professor Narsey also called for the removal of Section 131 of the 2013 Constitution, saying the Republic of Fiji Military Forces should have no role in civilian governance.
He says responsibility for internal security belongs to the Police, while the military should deal only with external threats.
He argued that Section 131, which assigns the military responsibility for the security, defence and well-being of Fiji and all Fijians, is an invitation to the military to do a coup when they feel like it.
Professor Narsey welcomed recent comments by the Republic of Fiji Military Forces Commander supporting the removal of constitutional immunity provisions and says he was very happy the Commander had taken that position.
He says every coup pushed Fiji backwards, with the country taking years to recover before returning to normal growth, but never recovering the ground that had already been lost.
He also said the full truth behind Fiji's coups has never emerged.
He questioned who was really behind the 1987 and 2000 coups and said there are still unanswered questions about the events leading up to the 2006 coup.
