The Australasian Catholic Press Association annual award for the best news story was announced at the organisation's annual conference this week in Auckland.
The article is credited with influencing authorities to reverse the ban.
The judges said: "By shining the light onto the clash between secular and bureaucratic rules and spiritual beliefs it emphasised the danger of blind adherence to regulations."
Abraham's article was published in the country's national Catholic newspaper NZ Catholic. The paper won the other major award, the Bishop Phllip Kennedy memorial prize for the best newspaper.
The judges said NZ Catholic is "in touch with the community", and does not fall into the trap of simply "reproducing religious tracts".
The Bishop Phllip Kennedy memorial prize for the best religious magazine went to Echo from Africa, produced by the Missionary Sisters of St Peter Claver.
