The Police Commissioner Fuiavaili'ili Egon Keil has cautioned against violence in the process.
"Our plea to the families in this area is to keep the peace and let the police do their job," he said.
Last week a member of one of the families involved told the Samoa Observer newspaper that she would not vacate the land.
"They can dig a mass grave and bury us in it, or kill us," said Aiga Tokuma.
"Only then they [the Government] can occupy this land; but we will not go down without a fight," she said.
