succeed Key. Post-premiership Following his resignation, Key stated that he would leave Parliament before the 2017 general election. However, he stated that he would resign within six months of the election so as to not trigger a by-election in the electorate. He gave his valedictory speech in Parliament on 22 March 2017 and formally resigned the following month, on 14 April. In May 2017, Key was appointed to the board of directors of Air New Zealand, and took up the position on 1 September 2017. He was also appointed chairman of ANZ Bank New Zealand, taking up the position on 18 October 2017. On 31 March 2020, Key stood down as a director of Air New Zealand.

In 2013 he expressed support for same-sex marriage and voted for the Marriage (Definition of Marriage) Amendment Act 2013. In 2008 Key voted for an attempt to raise the legal drinking age from 18 back to 20, but ignored a Law Commission recommendation to increase levies on alcohol. He claimed there was "no appetite" for such a move. A report on public attitudes to alcohol law reform was later discovered, which indicated that in 2010, when he made this claim, 56% of New Zealanders supported a price increase.
