Ardern (37) is New Zealand's youngest leader in 150 years
New Zealand will get its youngest prime minister in more than 150 years after the small, nationalist New Zealand First Party agreed to form a new government with Labour Party leader Jacinda Ardern, ending the National Party's decade in power.
The outcome caps a remarkable rise for Ardern (37), who only took over the party's top job in August, and marks another victory for a youthful global leader promising change.
The election on September 23 gave neither Labour nor National enough seats to form a majority in parliament.
"Their tighter immigration proposals and more restrictive housing policy all suggest economic growth could be a little bit weaker than the National's policy," Paul Dales, chief Australia and New Zealand economist at Capital Economics, said.
