In the 1907 electoral redistribution, a major change that had to be allowed for was a reduction of the tolerance to ±750 to those electorates where the country quota applied. The North Island had once again a higher population growth than the South Island, and three seats were transferred from south to north. In the resulting boundary distribution, every existing electorate was affected, and three electorates were established for the first time, including the Taumarunui electorate. These changes took effect with the 1908 election.[1]
In the 1918 electoral redistribution, the Taumarunui electorate was abolished, and the vast majority of its area went to the Waitomo and Waimarino electorates.[4]
