Their ancestors were taken as political prisoners from Taranaki in the 19th century to work in Dunedin.
Will Edwards, Te Korowai o Ngaruahine chairman in Taranaki, said the journey was to host a hikoi honouring the prisoners of the past.
''They were pacifists, revolutionaries, and stood up for what they believed in.
''It [the journey down] is also to seek resolution - the city council has already started to do that.''
Both young and old attended, and Mr Edwards said some of the older members of the gathering could be great-grandchildren of the prisoners.
The hikoi featured formal and sacred waiata (songs), speeches, a poi performance and a gathering around the kohatu (memorial stone).
