The Tongan government is reported to have lifted a state of emergency declared in November 2006.
It was imposed across the kingdom after much of the centre of the capital, Nuku'alofa, was destroyed when violence erupted during demonstrations in support of democratic reforms.
It was later restricted to the centre of the capital.
The prime minister's adviser, Lopeti Senituli, has confirmed that the emergency regulations have not been renewed.
However, the Tongan authorities have yet to make a public announcement to that effect.
Throughout the time the measure was in place the Government maintained it was needed because of the threat posed by elements supporting the pro-democracy movement.
