Winston Raymond Peters (born 11 April 1945) is a New Zealand politician and leader of New Zealand First, a political party he founded in 1993. Peters has had a successful and turbulent political career since entering Parliament in 1978, first serving as a Cabinet Minister in the Bolger Government before being sacked in 1991. As leader of New Zealand First, he held the balance of power after the 1996 election and formed a coalition with National, securing the positions of Deputy Prime Minister and Treasurer. However, the coalition dissolved in 1998 following the replacement of Bolger by Jenny Shipley as Prime Minister.

In 1999 New Zealand First returned to Opposition before entering into a government again with the Labour Party in 2005, in which he served as the Minister of Foreign Affairs. On 29 August 2008 he stood down as a Minister pending a police investigation into a funding scandal involving Peters and New Zealand First.

In the 2008 general election, New Zealand First failed to reach the five percent threshold and Peters did not regain his seat. As a result, neither Peters or New Zealand First were returned to Parliament. However, in the 2011 general election New Zealand First experienced a resurgence in support, winning 6.59 percent of the party vote to secure eight seats in Parliament.

John Phillip Key (born 9 August 1961) is the 38th Prime Minister of New Zealand, in office since 2008. He has led the New Zealand National Party since 2006.

Born in Auckland before moving to Christchurch when he was a child, Key attended the University of Canterbury and graduated in 1981 with a bachelor of commerce, also later undertaking management studies at Harvard University in Boston. He began a career in the foreign exchange market in New Zealand before moving overseas to work for Merrill Lynch, in which he became head of global foreign exchange in 1995, a position he would hold for six years. In 1999 he was appointed a member of the Foreign Exchange Committee of the Federal Reserve Bank of New York until leaving in 2001.

Key entered the New Zealand Parliament representing the Auckland electorate of Helensville as one of the few new National members of parliament in the election of 2002 following National's significant defeat of that year. He has held the seat since then. In 2004, he was appointed Finance Spokesman for National and eventually succeeded Don Brash as the National Party leader in 2006. After two years as Leader of the Opposition, Key led his party to victory in both the November 2008 and the November 2011 general elections.
