Jacinda Ardern was officially replaced on Wednesday as New Zealand prime minister, after stunning the country by announcing her abrupt departure from the role last week. New Prime Minister Chris Hipkins, 44, was sworn in by New Zealand’s governor-general during a ceremony in the capital, Wellington. Ardern said last week she no longer had “enough in the tank” after steering the country through natural disasters, its worst-ever terror attack and the COVID-19 pandemic.
