The most diverse cabinet in New Zealand's history was sworn in on Friday (November 6).
It includes the first female foreign minister - Nanaia Mahuta - who also happens to be Maori and has a facial tattoo.
She sang as she entered the ceremony, and chose to recite her oath in her indigenous language.
Of the 20-strong body eight are women, five are Maori, and three are LGBT.
Finance minister Grant Robertson takes up the post of Deputy Prime Minister, he's the first openly gay man to hold the position.
Ardern acknowledged the attention her appointments had drawn, but emphasised their experience and talent:
"This group of people have been described in public in many different ways. I'd say simply that sitting at this table is Aotearoa, New Zealand. They collectively represent a range of different perspectives. They represent huge talent, they represent enormous experience and as you would expect at any time of crisis, as New Zealanders, they have a huge commitment to serving this country."
Last month, Ardern's Labour Party won its best election result in half a century.
Labour increased its parliamentary majority further on Friday, after the result of postal and other special circumstance votes came in.
Labour now has 65 seats in the 120-seat assembly.
