The Greens' new Mt Albert candidate, who will be going toe-to-toe with Jacinda Ardern come September 19, was one of 14 teenagers who was kicked out of Parliament last year.
Luke Wijohn, 17, received a one-year ban from Parliament grounds after causing a disturbance in the public gallery in August.
After Question Time, Wijohn and the other 13 sang the Māori waiata Tutira Mai Nga Iwi while flying the Tino Rangatiratanga flag in gallery.
They said it was a peaceful action meant to draw MPs' attention to the Ihumātao hikoi, which was making its way to Prime Minister Jacinda Ardern's Mt Albert office at the time.
They were kicked out by Speaker Trevor Mallard, who banned them from Parliament for a year.
