Alfred Cadman Liberal James McGowan Liberal The Thames by-election of 1893 was a by-election held during the 11th New Zealand Parliament in the electorate of Thames.

The by-election was caused after the resignation of Liberal Party MP Alfred Cadman.

The Liberals selected the incumbent Mayor of Thames, James McGowan as their candidate for Cadman's seat.

After a large public gathering, it was decided not to run another candidate against McGowan in light of a general election being only months away, resulting in McGowan being elected unopposed.
