John Key

Key led the National Party to victory, winning 58 seats to Labour's 43. He became Prime Minister, succeeding Helen Clark, and formed a minority government with support from ACT, United Future, and the Maori Party.

Key's government implemented a series of economic stimulus measures, including tax cuts, infrastructure spending, and a deposit guarantee scheme. New Zealand avoided recession and recovered faster than many comparable economies.

Key's government coordinated the national response to the Christchurch earthquake that killed 185 people. The government established the Canterbury Earthquake Recovery Authority and committed billions to rebuilding.

Key's government supported the Marriage (Definition of Marriage) Amendment Act, legalizing same-sex marriage in New Zealand. The bill passed 77-44, making New Zealand the first Asia-Pacific country to legalize same-sex marriage.

Key unexpectedly resigned as Prime Minister and National Party leader, citing family reasons. He was succeeded by Bill English. Key left with high approval ratings and a stable economy.
