New Zealand Prime Minister Jacinda Ardern, who became the first world leader in more than 30 years to give birth in office, announced that she plans to return to work soon after a six-week maternity leave.

The 37-year-old prime minister appeared in the video along with her daughter, Neve Te Aroha Ardern Gayford, whom she gave birth to on June 21.

“It’s really heartening to be spending the first week back on deck on issues that really matter to me but also really matter to this government and to the Labor Party,” Ardern said in a live video on her Facebook page.

Ardern also said in the video that she plans to focus on issues like mental health once she makes her return to office on Thursday.

Ardern, who is the second elected world leader to give birth in office, also thanked New Zealand First leader and Deputy Prime Minister Winston Peters for serving as acting prime minister in the country while she was on maternity leave.

“We’re all doing really, really well,” Ardern said.

Ardern became prime minister in October. She is the country's youngest premier since 1856.

The prime minister giving birth while in office has been touted as a sign of progress for women. Former prime minister Helen Clark praised the prime minister and her partner’s parenting arrangement last month as an example of gender equality after the birth.
