New Zealand by-election
The 1878 Waipa by-election was a by-election held on 24 July 1878 during the 6th New Zealand Parliament in the electorate of Waipa in the Waikato.
The by-election was caused by the resignation of the incumbent MP Alfred Cox on 13 June 1878.
The by-election was won by Edward Graham McMinn, described as a Government supporter. Special trains ran from Auckland to Mercer to poll the Auckland voters, with 60 to 70 availing themselves of this conveyance.
Frederick Alexander Whitaker opposed the government of George Grey. There were reportedly "nearly forty natives on the roll, besides some ninety votes about Auckland" (for whom the nearest polling booth was Newcastle). Whitaker lost the by-election, but won the seat in the 1879 election, and McMinn came third (Waipa voted on 10 September 1879).
