Wellington business owners are expecting a peaceful protest.  The Hīkoi mō te Tiriti march has arrived in Wellington and will soon march to Parliament, protesting ACT’s Treaty Principles Bill.  Up to 30,000 people are expected to join the protest, disrupting traffic in the city.  Business Central Chief Executive Simon Arcus expects a "low impact" day.  But he told Mike Hosking there is some anxiety, particularly for businesses in the area around Parliament and the Wellington Railway Station.  LISTEN ABOVE  See omnystudio.com/listener for privacy information.
