He wrote an 1000-page description of the nun's life. It was unanimously approved by church historians in 2013, and then by a committee of church theologians.
Next a group of cardinals and bishops can declare Suzanne Aubert a "woman of heroic virtue", giving her the title of Venerable. Fr Carmody is hoping that will happen this year.
To get full sainthood, miracles will have to be attributed to her. This can happen if a person who needs medical help asks Mother Aubert to intercede with Christ for them.
If those prayers are successful, the cure can be deemed a miracle.
Fr Carmody is now the priest at St Theresa's Catholic Church in Plimmerton. He said he had put the case as far as he can.
Meanwhile Wellington's Sisters of Compassion are about to build an annex to their Island Bay chapel. Mother Aubert's remains are to be moved there, where people can visit them.
