Father of the House
In New Zealand, the term "Father of the House" (alternatively, "Mother of the House"), as an unofficial title, designates the longest-continuously-serving MP of the House of Representatives. The Father of the House has no official role in Parliament. Speaker Trevor Mallard became the longest-serving member in June 2021, having served continuously since the 1993 general election, with a previous period of service from 1984 to 1990.
