She said it was awesome to see such a great turn out.
"It's important for me because I see so much value in te reo Māori. I wish that one day it'll be just as frequently spoken as English here in New Zealand."
Wellington City deputy mayor Jill Day was encouraged by the turnout.
She was the driving force behind the Te Tauihu policy that's hoping to make te reo more visible in Wellington and for it to become a te reo Māori capital by 2040.
The council had recently renamed Civic Square to Te Ngākau Civic Square, a name that was gifted by local iwi. Day said they were already working on other bilingual place names for the city.
She said she would love other councils to consider following in Wellington's footsteps.
"There's a real interest in our country...other councils are really keen to follow suit which is fantastic."
"The revitalisation of te reo has been happening for many years and it's great to see it start to really get legs and be seen in a different way."
Members of the public stopped to watch and take photos of the parade on their lunch break.
Many school students held signs as they marched. One said "Toku reo Toku ohoho" "My language is my awakening"
The hīkoi was met by a kapa haka group on the steps of the square.
