Terence Michael "Terry" Heffernan (3 February 1952 – 13 March 2010) was a New Zealand politician who stood for Parliament on eight separate occasions. Heffernan was originally a member of the Social Credit Party before joining the New Zealand First Party and later, the New Zealand National Party.
He was born in Oamaru and attended St Bede's College in Christchurch. He obtained a degree in history and economics at the University of Canterbury after starting an accounting degree. He taught at Christchurch Boys' High School and Xavier College, but with a passion for politics became a parliamentary researcher for Bruce Beetham and then Winston Peters. He admired 1930s Labour politicians Savage and Lee.
Heffernan stood in the Wanganui electorate in five general elections:
- in 1981 for the Social Credit Party
- in 1984 for the Democratic Party
- in 1987 for the Democratic Party
- in 1990 for the Alliance Party
- in 1993 for the New Zealand First Party
Heffernan died in Christchurch on 13 March 2010, and his funeral was celebrated in St Joseph's Catholic Church in Papanui, Christchurch. A notice of motion in remembrance was lodged by Ruth Dyson in parliament on 18 March 2010.
