Bay of Plenty is a New Zealand electoral division returning one member to the New Zealand House of Representatives. The current representative is Todd Muller of the National Party, first elected at the . He replaced Tony Ryall, also of the National Party, who retired after representing the seat since . Population centres In the 1892 electoral redistribution, population shift to the North Island required the transfer of one seat from the South Island to the north. The resulting ripple effect saw every electorate established in 1890 have its boundaries altered, and eight electorates were established for the first time, including Bay of Plenty. Bay of Plenty was created for the change to the mixed-member proportional (MMP) representation voting system; it was carved out of parts of the old seats of Kaimai, Tarawera and Eastern Bay of Plenty. Its original incarnation was based mostly around Whakatane and Opotiki districts, with the remaining population coming from Te Puke and parts of greater Tauranga. The current Bay of Plenty electorate is wrapped around Tauranga city, but does not include the city. Up until the 2019–20 review, it included Matakana Island. Prior to the 2007 boundary review, it did not extend to the western side of Tauranga or to Matakana Island. Instead it comprised a section of the central Bay of Plenty coast, from the eastern periphery of the Tauranga urban area to outside the main populated part of Whakatane. It included the towns of Te Puke, Edgecumbe and Papamoa. Rapid population growth around Tauranga has driven considerable boundary change at each review. For the 2008 election, the eastern boundary moved far westwards to the eastern fringe of Te Puke, in the process abandoning sections of the central coast to the Rotorua and East Coast seats.
