Mr Peterson said he suspected history will look upon the Peace Hikoi as being as important in the nation's development as the Dame Whina Cooper land march. A feature of the hikoi had been the spirit in which it had been carried out, and received.
"There were no placards, no protesters anywhere and no abuse from drivers who passed us," he said.
Mr Peterson said people should keep in mind the commitment to the Treaty of Waitangi was bipartisan on a national level and that as the young people of today grew into adulthood their views would be "further along the continuum" than now exists and far in advance of attitudes in years gone by.
While in Taranaki Mr Peterson had the chance to meet and talk with the organiser of the hikoi, New Plymouth mayor Andrew Judd, who was formerly from Masterton.
Mr Judd has gone on record to pledge his support for a Masterton District Council decision to appoint two iwi representatives to its standing committees with full speaking and voting rights.
Mr Peterson said reflecting on the debate that followed that decision, and in light of the hikoi, he feels even more confident the decision was the right one.
"I have more understanding as to why we made the decision, having had a chance to chat about it with people I know and respect.
"I know some people feel it is racist and is an erosion of democracy but it is not that.
"It does not undermine democracy," he said.
