A newspaper in Fiji reports the interim military administration has invoked Public Emergency Regulations which effectively place the country under emergency rule.
The Fiji Times says the police arrived at its offices on Good Friday afternoon with papers indicating that Public Emergency Regulations have been put in place.
Editor Netani Rika told Radio New Zealand the protocol will see all political stories monitored by the Ministry of Information.
The Court of Appeal ruled on Thursday that Fiji's interim government was unlawful.
President Ratu Josefa Iloilo revoked the 1997 constitution on Friday.
Commodore Frank Bainimarama overthrew the elected government in December 2006. It was the fourth coup in Fiji since 1987. He was later appointed interim prime minister.
The ABC reports Commodore Bainimarama says he had nothing to do with the president's decision to annul the constitution.
He told Radio Australia's Pacific Beat programme he did not instruct Mr Iloilo to abolish the constitution.
Swearing-in being held
The President is holding a swearing-in ceremony at Government House in Suva on Saturday morning.
The Ministry of Information would not give any details as to was being sworn in at the ceremony, which was to start at 10am.
International media have been banned from attending.
