Question: Who married the man who wanted to reform the institution behind the denomination constituting 12.6% of Christians in New Zealand?

Passages:
Christianity is the predominant religion in New Zealand, although its society is among the most secular in the world. In the 2013 census, 55.0% of the population identified with one or more religions, including 49.0% identifying as Christians. Another 41.9% indicated that they had no religion. The main Christian denominations are, by number of adherents, Roman Catholicism (12.6%), Anglicanism (11.8%), Presbyterianism (8.5%) and "Christian not further defined" (i.e. people identifying as Christian but not stating the denomination, 5.5%). The Māori-based Ringatū and Rātana religions (1.4%) are also Christian in origin. Immigration and demographic change in recent decades has contributed to the growth of minority religions, such as Hinduism (2.1%), Buddhism (1.5%), Islam (1.2%) and Sikhism (0.5%). The Auckland Region exhibited the greatest religious diversity. Many Christians still practice their traditional cultural beliefs and rituals along with Christianity. The Catholic Church has fused some aspects of local culture into its services. For example, the singing of hymns during services has developed into a local and traditional way of singing (a repetitive call and response style) in Sesotho, the indigenous language, as well as English. In addition priests are seen dressed in local dress during services. Although there had been significant earlier attempts to reform the Catholic Church before Luther -- such as those of Jan Hus, Peter Waldo, and John Wycliffe -- Martin Luther is widely acknowledged to have started the Reformation with the Ninety - five Theses. Luther began by criticising the sale of indulgences, insisting that the Pope had no authority over purgatory and that the Catholic doctrine of the merits of the saints had no foundation in the Bible. The Protestant Reformation, however, would come to incorporate doctrinal changes such as a complete reliance on Scripture as a source of proper belief (sola scriptura) and the belief that faith in Jesus, and not good works, is the only way to obtain God's pardon for sin (sola fide). The core motivation behind these changes was theological, though many other factors played a part, including the rise of nationalism, the Western Schism that eroded loyalty to the Papacy, the perceived corruption of the Roman Curia, the impact of humanism, and the new learning of the Renaissance that questioned much traditional thought. Katharina von Bora (; 29 January 1499 – 20 December 1552), after her wedding Katharina Luther, also referred to as "die Lutherin" ("the Lutheress"), was the wife of Martin Luther, German reformer and a seminal figure of the Protestant Reformation. Beyond what is found in the writings of Luther and some of his contemporaries, little is known about her. Despite this, Katharina is often considered one of the most important participants in the Reformation because of her role in helping to define Protestant family life and setting the tone for clergy marriages.
