The Thames by-election of 1909 was a by-election held during the 17th New Zealand Parliament.
The by-election was caused after the resignation of Liberal Party MP James McGowan, who had been appointed to the Legislative Council. McGowan announced his resignation by advertisement in the Thames Star on 7 January 1909, and in the same edition, the Mayor of Thames, Archibald Burns, announced his candidacy.[1]
In the end, five candidates contested the election, but Burns was not among them. William Henry Lucas, a unionist, was the official representative of the liberal government.[2] Edmund Taylor and Thomas William Rhodes were also Liberal Party member. Frederick Henry Haselden was the official candidate of the conservative opposition, but Ernest Deeble also stood for opposition interests.[3] [4]

That election was held on 4 February 1909, and was won by Taylor.
