Hīkoi participants are beginning to arrive in Wellington's Waitangi Park where they'll travel to Parliament.  

Police say traffic on State Highway 1 is starting to build and people should avoid travelling this morning.  

Traffic management plans are in place, but people should also expect delays around central Wellington. 

Wellington Police District Commander Corrie Parnell told Mike Hosking that a month's work of planning has gone into it. 

He says there’s been a lot of meetings across different departments, but they’re well prepared for today’s events.
