Rotorua is a New Zealand parliamentary electorate, returning one Member of Parliament to the New Zealand House of Representatives. It was first established in 1919, and has existed continuously since 1954. The current MP for Rotorua is Todd McClay of the National Party, who won the electorate in the 2008 general election from incumbent Labour MP Steve Chadwick.
In the 1918 electoral redistribution, the North Island gained a further three electorates from the South Island due to faster population growth. Only two existing electorates were unaltered, five electorates were abolished, two former electorate were re-established, and three electorates, including Rotorua, were created for the first time.
The original electorate, which was formed through the 1918 electoral redistribution, had a long coastline along the Bay of Plenty, and incorporated, beside Rotorua, the towns and villages of Whakatane, Taupo, Tokoroa, Putaruru, Mangakino, Edgecumbe, Taneatua, and Murupara. In the 1922 electoral redistribution, the electorate lost some area to the Bay of Plenty electorate, and a larger area to the Waikato electorate. The 1927 electoral redistribution saw Rotorua become landlocked, with the Tauranga electorate taking the coastline including Taneatua and Edgecumbe, and Whakatane going to the Bay of Plenty electorate. The electorate moved south and took in Lake Taupo, with Turangi just beyond the southern boundary located in the Waimarino electorate. The electorate also grew in the north-west, gaining the town of Matamata.
