Prime Minister Tuilaepa Sailele Malielegaoi said on his weekly national radio programme that the country was governed by nearly 300 statutes.
But he said more than 100 of these needed to be repealed.
Tuilaepa said there were laws that needed to be reviewed and set for amendment in Parliament.
He said one of the pressing laws in need of reform was the Electoral Act, and the amendment bill had gone through its first and second readings.
"This law needs to be passed now as it will be used to govern the next General Elections," he said.
He was speaking on the Samoa Law Reform Commission reaching 10 years of service.
