Three months after the deadly violence on Manus Island there is still not a full-time psychiatrist on Manus Island's detention centre, despite Immigration Minister Scott Morrison assuring human rights organisations there was.

Amnesty International raised concerns with the immigration department after witnessing shocking living conditions on the island, following a tour of the centre in March. They also questioned whether a full-time psychiatrist was present in the centre.

In an email obtained by Fairfax Media, Mr Morrison wrote to Amnesty International on April 28 saying: ''The IHMS [International Health Medical Services] on-site team includes general practitioners, nurses, paramedics, mental health nurses, psychologists, counsellors and a full-time psychiatrist.''

Mr Morrison has conceded his department gave him the wrong information and the team had not yet hired a full-time psychiatrist.
