He later obtained a Bachelor of Laws from Victoria University of Wellington, and worked as a lawyer
He was an Member of Parliament from 1978 to 2002, representing the National Party. He served for three years as Speaker of the House of Representatives. From 1960 to 1964, he served in the New Zealand Army Territorial Force as a bombardier gunlayer.
He also had business interests in aquaculture, forestry, and wine making.
Kidd was first elected to Parliament in the 1978 election, becoming Member of Parliament for Marlborough. In the government of Jim Bolger, Kidd held a number of minor ministerial portfolios, including Fisheries, Energy and Labour.
He held his Marlborough electorate until the 1996 election, when the electorate was abolished and most of its area incorporated into the new and larger Kaikoura electorate. Kidd came first in Kaikoura in 1996 and held the electorate until the 1999 election, when he opted to become a list Member of Parliament. He was succeeded in Kaikoura by Lynda Scott.
Status of the Unborn Child Bill
In 1983 Kidd"s pro-life Status of the Unborn Child Bill (a private members bill) was drawn from the lot.
The bill was prompted by Wall v Livingston, which clarified that embryos and fetuses had no legal status in New Zealand and that third parties could not appeal to the courts on their behalf. The bill was supported by groups such as Society for the Protection of the Unborn Child (now Voice for Life and Right to Life New Zealand) but defeated by pro-choice groups led be Marilyn Waring. Speaker of the House
After the 1996 election, Kidd was elected Speaker of the House of Representatives.
Derek Quigley also contested the position.
He replaced Peter Tapsell, a Labour Party Member of Parliament who had held the speakership because National did not want to lose a vote by appointing a Speaker from its own ranks. As the government"s majority was now not so precarious, and as Tapsell had lost his seat in any case, National was able to appoint Kidd without difficulty.
Kidd lost the speakership when the National Party lost the 1999 election, being replaced by Jonathan Hunt of the Labour Party. After serving a term in Opposition, he chose to retire from politics at the 2002 election.
He was appointed to the Waitangi Tribunal in 2004.
