Police say about 2000 people are walking from Petone to the Wellington train station along State Highway 2 this morning, as part of the hīkoi mō Te Tiriti.
The group set off at 4am, with cars travelling slowly alongside in support.
Tens of thousands of protesters are expected at Parliament today, as Hīkoi mō te Tiriti reaches its final destination.
It's the end of a nine-day trek for many who oppose the Treaty Principles Bill, which is being sponsored by the ACT party.
Those walking are flying hundreds of tino rangatiratanga flags, while many drivers are tooting as they pass the hīkoi.
Participants are aged from young children to the elderly.
Here's a sample of some of those taking part.
