Jacinda Ardern has invited one of her former high school teachers to the ceremony tomorrow when she will be sworn in as Prime Minister.
Ministers are allowed to bring two people, however, Ms Ardern has been allocated five seats for the ceremony at Government House in Wellington.
"So my father will be joining me, my partner and my old high school teacher," she told Breakfast today.
"I really credit my teachers in my life as playing a big role in where I am so it'll be lovely to have him join me."
Gregor Fountain, the now-principal of Paraparaumu College, taught Ms Ardern social studies at Morrinsville College.
Ms Ardern previously told Noted he had a memorable teaching approach.
"I think you remember these moments in education when you transition from just finding out information to finding out how to think, and he was my teacher when I found out how to think," she said.
"That was an incredibly important period."
Ms Ardern told TVNZ1's Breakfast that Mr Fountain was a "wonderful teacher".
