After completing his mandatory residency, he was between 1989 and 1990 employed as the prison doctor at Ullersmo Prison. He worked as a physician from 1989 to 1994 and 1997 to 2000, and was chief physician at Aker University Hospital before becoming head of the psychiatric division at Ullevål University Hospital between 2004 and 2009.[1][5]
In 2011, Mæland was one of two applicants to the position as director of the National Police Directorate replacing outgoing Ingelin Killengreen. The other applicant was Christine Fossen, then Chief of Police in the Southern Buskerud Police District.[7] In the end, Mæland was selected. He was appointed on 27 May 2011, mere weeks before the 2011 Norway attacks. During most of the period following the attacks, Mæland was away on paternity leave[8][9] On 13 August 2012 the Gjørv Report was released. It found that the authorities in general, and the police in particular, failed massively in protecting the public during the 2011 Norway attacks.[10]
In the aftermath, Mæland stated that he fully accepted the criticism of the commission's findings and intended to remain in his post, there were calls for his immediate resignation which were repeatedly rejected. The same evening the report was released, Mæland himself appeared on television saying he would not resign.[11] Three days later on 16 August 2012, Minister of Justice Grete Faremo, which was Mæland's immediate superior, announced during a live television debate that she would henceforth recuse herself from all matters relating to him, as to avoid a conflict of interest.[12] This was allegedly due to the close professional relationship the two had when Mæland was state secretary for Faremo during the 90's.[13]
This was interpreted by the media as a sign that the minister lacked confidence in Mæland, and that it was a step in the process of removing him from the post altogether.[14] One scholar described it as a "humiliation" and a "sacking".[15] 25 minutes after the ministers announcement, Mæland publicly informed the Minister of his immediate resignation.[16]
Mæland is openly gay, and is married to psychotherapist and relationship counsellor Rolf Nicolay Aspestrand. The couple have two children, both of which were born through surrogacy in the United States and subsequently adopted.[3][17] Mæland and his family currently resides in the borough of Nordberg in Oslo.[2]
