"We will definitely finish resettlement by January 31 and by that date we will close down all camps", Minister of Resettlement Rishath Bathiyutheen told reporters here Monday.
Bathiyutheen said some 100,000 still left to be resettled after action that had seen to the resettlement of over 150,000.
Over 275,000 Tamil civilians were displaced from the north and east regions when the war with the Tamil Tigers ended in mid May.
The civilian population living in the former Tamil Tiger regions were housed since May in welfare camps in the northern town of Vavuniya.
Following international criticism of camp conditions the government allowed free access and made them open camps enabling inmates to move in and out freely.
