The Ministry of Immigration in Papua New Guinea says all asylum seekers detained on Manus Island are now free to come and go from the processing centre.
About 900 asylum seekers who were refused entry to Australia were detained on the island but the PNG Supreme Court ruled their detention is illegal.
The Deputy Chief Migration Officer Esther Gaegaming said the Immigration Ministry was committed to complying with the orders of the Supreme Court to cease detention.
Ms Gaegaming said all residents at the regional processing centre at Lombrum Naval Base were free to come and go.
She said they had been encouraged to relocate to the Manus Island Refugee Transit Centre in East Lorengau.
