RNZ reports Baron Waqa accused the foreign media of using Nauru as a punching bag.
The President's comments, in an article in the Australian newspaper, came two weeks after the publication of more than 2,000 reports of abuse or mistreatment of inmates in the Australian-run detention centre on the island.
This was preceded by a review conducted by Amnesty International that graphically detailed the extent of the abuse and ill treatment.
But Mr Waqa said Nauru hosted the refugees and asylum seekers with compassion, understanding and professionalism.
