New Lynn is a New Zealand parliamentary electorate, returning one member to the New Zealand House of Representatives. The current representative is David Cunliffe, former leader of the Labour Party. In November 2016, Labour leader Andrew Little announced that Cunliffe would not seek re-election at the 2017 general election.
New Lynn is based in west Auckland, straddling the borders of the former Auckland City and Waitakere City. It contains the suburbs of Blockhouse Bay, New Lynn and Titirangi, and its borders extend to cover all the beach-side towns on the north coast of Manukau Harbour.
New Lynn was first formed for the 1963 election. It has always been held by members of the Labour Party. The electorate's first representative was Rex Mason, who had been an MP since 1926 and who retired at the end of the term. Mason was succeeded by Jonathan Hunt, who held the electorate for the next 30 years until he contested the Tamaki electorate in the 1996 election instead.Phil Goff became the representative in New Lynn in 1996.
The electorate was abolished in 1999 and Goff successfully stood in Mount Roskill. Titirangi replaced New Lynn in 1999 when population changes in Auckland lead to the creation of Mount Roskill, and Titirangi was won by David Cunliffe. Three years later, population growth in north Auckland led to the creation of Helensville. The flow-on effect of this was to pull Titirangi eastwards, resulting in the reclamation of its former name for the 2002 election. Since then, Cunliffe has represented the New Lynn electorate.
