"On 28 May 2011 Father Couture, the District Superior, came to visit our Convent. He had been delegated by Bishop Fellay to receive the vows of Mother Mary Micaela as she transferred from the Congregation of the Dominican Sisters of New Zealand to the Dominican Sisters of Wanganui. [A congregation "friendly" with the Priestly Fraternity of Saint Pius X - FSSPX / SSPX.]
"She had special permission from the Congregation for Religious and Secular Institutes in Rome to do this. As far as we know this is a world first, that a Sister would be allowed to transfer from a Novus Ordo congregation to a congregation set up by Bishop Fellay. The whole procedure implies a recognition of our Congregation, and of the religious of Tradition, by Rome."
