The order, which was confirmed yesterday (June 14), has been imposed since a suicide attack on a police bus carried out in November 2015.
The incident followed the terror attack in the resort of Sousse in which 30 British holidaymakers were killed, two years ago later this month.
After the extension was confirmed, the Foreign Office (FCO) said: “Since the terrorist attack in Sousse in June 2015 which targeted tourists, the UK government has been working closely with the Tunisian authorities to investigate the attack and the wider threat from terrorist groups in Tunisia.
