The beatification process was set to commence in Bolzano after rights for the cause transferred from Bamberg to Bolzano on 23 February 1991.
However, the cause did not receive the formal approval from the Congregation for the Causes of Saints until 30 September 2005 at which point he was granted the title Servant of God and the diocesan process could begin.
The diocesan process spanned from 24 February 2006 until 19 March 2007 when all documents collated were sent to Rome for further inspection.
The decree of validity on the process was granted several years later on 23 April 2010 and allowed for the postulation to draft the Positio on his martyrdom.
The Positio was submitted to the C.C.S. in January 2015.

It had been reported that Mayr-Nusser's beatification would take place in Bolzano in 2016 since theologians advising the C.C.S. had approved the cause on 29 October 2015 and passed it to the members of the C.C.S. itself for their decision on 21 June 2016 who also approved it.

Pope Francis approved the beatification on 8 July 2016 and he was beatified in Bolzano on 18 March 2017 with Cardinal Angelo Amato presiding over the celebration on the pope's behalf.

The current postulator of the cause is Carlo Calloni, O.F.M. Cap.
The first postulator assigned was Josef Innerhofer.
