Prime Minister Jacinda Ardern is set to feature in Vogue magazine, following in the footsteps of former US First Lady Michelle Obama and Canadian Prime Minister Justin Trudeau.

An interview has already been done, a spokesperson for Ms Ardern confirmed to NZME, and a photoshoot featuring all Kiwi designers will take place this weekend.

Ms Ardern will appear in the American edition of what's been described as "fashion's bible", but not on the cover.

The magazine has never featured a female politician on its cover, although Ms Obama and Hillary Clinton both appeared as First Lady.

Ms Ardern gained worldwide attention during her election campaign, which saw Labour climb in the polls to win 36.9 percent of the vote come September 23.

After New Zealand First leader Winston Peters announced a coalition with Labour, boosting Ms Ardern to Prime Minister, Mr Trudeau was among the first of the world's leaders to offer congratulations, along with the UK's Theresa May, who called Ms Ardern directly.

Britain's The Guardian called her a "reluctant leader", lauding her "political nous", "youth and energy" and "uncultivated charm and humour", while The Independent said she was "good news for New Zealand".

BBC analyst Hywel Griffith was less optimistic, saying she had plenty on her to-do list and would find it a challenge to deal with the fractious relationship of Mr Peters and Greens leader James Shaw.

Among the more obscure celebrities offering their congratulations was US comedian Greg Proops, of Whose Line is it Anyway? fame, who called Ms Ardern "a progressive woman".

Now, it seems, the international interest in the 37-year-old continues.
