Adam Hamilton (20 August 1880 – 29 April 1952) was a New Zealand politician. He was the first non-interim Leader of the National Party during its early years in Opposition. Early life Hamilton was born in Forest Hill, near Winton, Southland. He originally trained to become a Presbyterian minister, but later decided not to pursue this course. He married Mary Ann McDonald in 1913, and in 1914, he and his brother John Ronald Hamilton started a grain business in Winton. In World War I, he was rejected for service on medical grounds. Member of Parliament In the 1919 election, Hamilton was elected to Parliament in the Southland seat of Wallace, standing as a Reform Party candidate.

Hamilton denied knowledge of the jamming, but his reputation was nevertheless damaged. In 1935, Hamilton was awarded the King George V Silver Jubilee Medal. Having served as a member of the Executive Council for more than three years, Hamilton was granted the retention of the title of "Honourable" following the 1935 election. Party leader In 1936, after losing power to the Labour Party, Reform and United agreed to merge, creating the National Party. Despite his somewhat tarnished public image, Hamilton was selected to lead the new party, taking over from interim leader George Forbes. Hamilton was essentially a compromise candidate – Forbes and his main opponent, Gordon Coates, refused to serve under each other, and the Coates faction backed Hamilton as an
