LGBT Labour MP Kiri Allan has been appointed Conservation Minister, replacing Green MP Eugenie Sage.
Three ministers of the 20-strong Cabinet are also of Pasifika descent - Poto Williams, Carmel Sepuloni and Kris Faafoi.
"It is both a Cabinet with huge merit and talent, which also happens to be incredibly diverse," Ardern told reporters on Monday following her announcement.
"I think it’s an important point to make - these are individuals who have been promoted for what they bring to the cabinet, they also reflect the New Zealand that elected them."
Here's what the headlines are saying:"Ardern's changes to the Cabinet represent a bold political statement that places women, Māori and other minority groups in important decision-making roles," the Financial Times reported.
"It should help silence internal critics on the political left, who have alleged her government will be incrementalist rather than transformative, said Bronwyn Hayward, politics professor at University of Canterbury."
The Guardian reported New Zealand's diverse new government would focus on "COVID-19 containment and economic recovery".
"Of the 20-strong Cabinet, eight are women, five are Māori, three are Pasifika and three are LGBT," contributing writer Phil Taylor wrote from Auckland.
Nanaia MahutaThe majority of the news around New Zealand's new Cabinet focused on the appointment of Mahuta as Minister of Foreign Affairs.
The Guardian article referred to Mahuta as a "trailblazing MP", noting her milestone achievement as the first woman to hold the portfolio.
The Financial Times called her appointment the "biggest surprise" in the new Cabinet.
