WELLINGTON—Jacinda Ardern was sworn in as New Zealand’s 40th Prime Minister on Thursday, Oct. 26, more than a month after a tight election result.

Ardern became New Zealand’s third female prime minister and its youngest leader since 1872. The 37-year-old leader said her Labor-New Zealand First-Greens coalition has a responsibility to lead a “strong and empathetic” government for all New Zealanders.
