In October 2013, Statistics New Zealand announced that there would be one additional North Island general electorate, bringing the total number of North Island general electorates to 48 and the overall number of electorates to 71. Growth in Auckland saw three existing electorates, Auckland Central, Helensville and Hunua, exceed their quota by at least 14 percent. Population changes in Christchurch following the 2011 earthquakes meanwhile saw the Christchurch East electorate drop to 23 percent below quota, while the urban fringe electorate of Selwyn grew to 14 percent above quota.
