# Port Hills (New Zealand electorate)

Port Hills was a parliamentary electorate of New Zealand that existed for the 2008 through 2017 general elections. Ruth Dyson of the Labour Party had previously held the Banks Peninsula electorate since the 1999 election that was largely replaced by Port Hills, and held Port Hills for its entire existence before retiring ahead of the 2020 election. The Port Hills electorate was mostly urban, and lost the more rural Banks Peninsula areas of the old electorate to the Selwyn electorate that was also formed for the 2008 election.
Ahead of the 2020 election, the boundaries were again adjusted and Port Hills abolished. Most of its area is now covered by the Banks Peninsula electorate.

## Population centres

Port Hills was created after a review of electoral boundaries conducted in the wake of the 2006 census of population and dwellings. The bulk of Port Hills came from the old Banks Peninsula electorate, including the suburbs of Opawa and Woolston, the suburban areas around the Cashmere Hills, and the towns on the north coast of Lyttelton Harbour. The south Christchurch suburbs of Bromley and Sydenham have been added from Christchurch East and Wigram, respectively. Most of the electorate was urban.
The following suburbs, in alphabetical order, were at least partially located in the electorate: Balmoral Hill, Beckenham, Bromley, Cashmere, Cass Bay, Clifton, Corsair Bay, Ferrymead, Governors Bay, Heathcote Valley, Hillsborough, Huntsbury, Linwood, Lyttelton, Moncks Bay, Moncks Spur, Mount Pleasant, Murray Aynsley Hill, Opawa, Te Rāpaki-o-Te Rakiwhakaputa, Redcliffs, Richmond Hill, Scarborough, St Andrews Hill, St Martins, Sumner, Sydenham, Taylors Mistake, Waltham, and Woolston.
Port Hills was one of the electorates worst affected by the 2010 and 2011 earthquakes and suffered minor population loss as a result. The 2013 redistribution resulted in the electorate losing the areas around Bromley and Sydenham but regaining Halswell back from Selwyn.
Port Hills was abolished for the 2020 general election, being replaced largely by a recreated Banks Peninsula. This was to absorb population growth in neighbouring Selwyn.

## History

Because the new suburbs were strong Labour-voting areas, Banks Peninsula MP Ruth Dyson retained the electorate despite a nationwide swing to the National Party in 2008. This was also one of the electorates which elected a Labour MP but where the National Party won the party vote. National's candidate in 2008 was Terry Heffernan (1952–2010), who at that time was already weakened by cancer.
In the 2011 election, Dyson contested the electorate against David Carter. Dyson and Carter had contested before; in 1993, Dyson was successful in the Lyttelton electorate, but in 1996 in Banks Peninsula, Carter had the upper hand. In 1999, 2002, and 2005, Dyson was always in first place, and she was again successful in 2011.
In the 2014 election, the National Party put up Nuk Korako against Dyson; Carter had in the meantime been elected Speaker of the House of Representatives and as such, was not contesting an electorate any longer. Based on preliminary counts, Dyson has a majority of 1,865 votes over Korako.
In the boundary review of 2019/2020, the Representation Commission decided to make large changes to the boundaries of Port Hills, taking area in Halswell and parts of Bromley out and adding Banks Peninsula in, to manage large changes in population in the Christchurch and Selwyn areas. The electorate was also re-recreated as Banks Peninsula.
