Rongotai is a New Zealand electorate, returning a single member to the New Zealand House of Representatives. The current MP for Rongotai is Julie Anne Genter of the Green Party. She has held this position since the 2023 general election.

The Rongotai electorate is centred on the southern and eastern suburbs of Wellington City. It stretches from Miramar in the east to take in the suburbs of Rongotai, Kilbirnie, Lyall Bay and Hataitai and runs from the south coast at Island Bay up through the southern section of the Brooklyn Hill to an east–west border next to Wellington Hospital in Newtown. Because Wellington Airport is within Rongotai's boundaries, the constituency also contains the Chatham Islands. It is named after the suburb of Rongotai which is roughly in its centre. Other suburbs include Berhampore, Ōwhiro Bay, Seatoun, and Roseneath.

A revision after 1996 pulled the boundary southwards, moving the suburbs around the Basin Reserve and the Massey University campus into the Wellington Central electorate.^{[citation needed]} In the 2002 redistribution, the area covered by the Rongotai electorate did not change.^[1] Changes to boundaries were done in the 2007 redistribution,^[2][3] but no further changes were done in the 2013/14^[4] or 2019/20 redistributions.^[5]

Rongotai was one of the original 65 mixed-member proportional (MMP) representation electorates drawn in 1994 ahead of the 1996 election. It is the successor to the old Island Bay and Miramar electorates, though the areas in these seats in the orbit of the central city were incorporated into a redrawn Wellington Central electorate.

Labour's Annette King was elected and re-elected as the member of parliament for Rongotai at all seven elections from 1996 to 2014.^[6] In five out of the seven elections, Labour also won the party vote; the exception being in 1996 when National out-polled Labour by just 68 votes,^[7] and in 2014, when National's majority was 852 votes.^[8] Chris Finlayson of the National Party opposed King, his distant cousin, since the 2008 election. After the 2014 election, he told his supporters that on current trends, he should be able to win the electorate by 2038.^[9]

King announced in March 2017 that she was stepping down from her role as Labour's deputy leader and would retire from politics at the 2017 general election.^[10] The electorate of Rongotai was won in the election by Paul Eagle, retaining it for Labour.^[11]

During the 2020 general election, Eagle retained Rongotai for Labour based on preliminary results.^[12] Eagle announced in June 2022 that he would contest the 2022 Wellington City mayoral election and should he be successful, he would resign from Parliament and trigger a by-election.^[13]
