Paraparaumu College principal Gregor Fountain was at college on Saturday trying to write a prizegiving speech when he received a surprise text message from Jacinda Ardern.
She inquired if he would like to attend her swearing-in as the new Prime Minister of New Zealand - the answer was a very positive yes.
Mr Fountain's first teaching job was at Morrinsville College, in 1995, where he taught Ardern social studies [she was in his form class too] and then history over the next two years.
The pair have kept in contact and Ardern has spoken twice at Paraparaumu College's student leadership camp and spent a day at the college last year during Youth Week where she met with a range of students, worked with student leaders and spoke at a student led Pink Ribbon afternoon tea.
Mr Fountain was among various politicians and guests who took a bus from Parliament to Government House yesterday for the swearing-in as well as morning tea with Governor General Dame Patsy Reddy.
