The 1884 Thorndon by-election was a by-election held on 13 May 1884 for the Wellington urban electorate of Thorndon during the 8th Parliament. 
Wellington businessman William Levin resigned due to ill-health.[1] 
He was replaced by Dr Alfred Newman.[2] 
One of the losing candidates, Henry Bunny had represented the Wairarapa electorate from 1865 to 1881. He was widely expected to win.[3] 
Thomas Dwan did not impress one reporter at the opening meeting of the campaign, saying that he did not give his usual "political mountebank" speech but a deadly dull one, and that he showed he knew as much about the country districts as a "Hindoo does about skating".[4]
