Historical Data (1905-1993)

These excel files contain electorate by electorate data for all New Zealand elections between 1905 and 1993. They have been compiled over some years, and should now be free of errors. They include the totals, and both rounds, of the two Second Ballot elections in 1908 and 1911.

Users should note, however, that party labels for early elections were often fluid, and it has proven difficult to make party totals completely consistent with the official data reported in the successive E9 and earlier official results, and with the figures reported in Mackie and Rose's International Almanac of Electoral History. J. O. Wilson's New Zealand Parliamentary Record was used as a further source of data.

Thanks are due to the research assistants who worked on this: Philippa Miskelly, Jean Kite, and Sam Martin.
