New Zealand swears in new prime minister Christopher Luxon

Former airline executive Christopher Luxon is sworn in as New Zealand's next prime minister.

He heads a three-way coalition, in which his two deputy prime ministers, David Seymour and Winston Peters, will each hold the position for half of the government's three-year term.

The two deputies have in the past traded barbs and been involved in high-profile social media spats, but Luxon has downplayed the friction.

National's election win in October brought the curtain down on six years of Jacinda Ardern's Labour party.
