Norman John Kirk (27 June 1947 – before 4 March 2024) was a New Zealand politician from the Labour Party who served as the Member of Parliament for Sydenham in the South Island.

He returned to New Zealand and worked with the Waikato Times so his family could live in close proximity to Green Lane Hospital in Auckland after his daughter became seriously ill (and later died).

[5] When his father died in office in 1974, John Kirk contested the resulting by-election in the same year and succeeded him as MP for Sydenham.

His father had previously talked to his close colleague Warren Freer very frankly about his family, and made it quite clear that if any of his sons wished to have a political career, he hoped it would be Robert or Philip, but not John.

Constituents in Sydenham complained that he did not show up for public functions and did not address their concerns while other MPs feeling he was self-centred and opinionated.

[13] In July 1983 John Kirk announced that he would not seek the Labour Party's nomination for Sydenham in the 1984 election, having been informed by his local electorate committee they would not be supporting him for re-selection.

Kirk served out the remainder of his parliamentary career as an Independent MP after declaring that he would never again vote with the Labour Party.
