She wrote a book New and complete manual of Māori conversation : containing phrases and dialogues on a variety of useful and interesting topics : together with a few general rules of grammar : and a comprehensive vocabulary which was published in Wellington by Lyon and Blair in 1885.

[8] Although Aubert's childhood illness slowed her education, she quickly made up lost ground at a boarding school under the care of the Benedictine nuns of La Rochette.

Aubert went on to study music, fine arts, needlework, languages, and literature; she was an exceptional reader and read classical and devotional books.

[11] In 1859 Bishop Pompallier, visited his home town, Lyon, to recruit missionaries for his Auckland diocese and Aubert accepted the invitation.

[14] In 1862, Aubert and the Sisters of Mercy formed a new religious congregation in Freeman’s Bay named ‘The Holy Family’, under the jurisdiction of Bishop Pompallier, who was responsible for the teaching of Māori girls.

[15] Aubert's mentor in all things Māori was Hoki, known also as Peata, an influential and gifted relative of the powerful Ngapuhi chief, Rewa.

[17] Aubert, unwilling to give up and return to France, left Auckland to live and work at the Marist Māori mission station at Meanee in Hawke’s Bay with Father Euloge Reignier.

Aubert's Māori pupils went back to their Kainga, or villages, and Peata, now blind, returned home to Northland and died not long after.

[18] Aubert, now 35 years old and no longer a member of a religious congregation, arrived in Hawke's Bay to play her own part in the revitalization of the Catholic Māori mission.

Aubert settled into the French household, helped on the farm, taught catechism, trained the local choir, played the harmonium, embroidered and prepared the church for religious festivals, and soon became well known for her skillful nursing capabilities.

In 1879, Father Christophe Soulas arrived from France, familiarized himself with Māori families in the district, and constructed a new church at Pakipaki.

In 1883, Father Soulas and Suzanne Aubert left Hawke's Bay to go to Hiruharama, or Jerusalem, 60 kilometers up the Whanganui River.

The Sisters at Hiruharama, in addition to the usual customs of religious life, taught and nursed, farmed newly cleared bush, tended an orchard, made and marketed medicines, sold fruit to tourists and raised homeless children, as a result the community grew and thrived.

The much-needed home they planned for permanently disabled people would require trained nurses; so the Sisters of Compassion completed a St. John Ambulance Association course.

[20] Aubert and the Sisters pushed wicker collecting prams, begged for food, and cast-off clothing for distribution to the needy, becoming a familiar part of the city's daily life.

[22] In April 1917—four years and four months after Aubert arrived in Rome—Pope Benedict granted the Decree of Praise to the Daughters of Our Lady of Compassion.

[24] The process for Aubert's canonisation as a saint was commenced with the appointment in 2010 of Maurice Carmody as postulator or advocate for that cause; it is currently before the authorities in Rome.
