No mention of what they’re protesting but hopefully this isn’t some sort of attempt to repeat the literal shit-show from last year.
Edit: apparently it’s people gluing themselves to roads to promote trains. https://www.newstalkzb.co.nz/news/national/traffic-disruption-warning-by-police-ahead-of-restore-passenger-rail-protest/
As I said in another comment, it’s hard to ignore a protest of tens of thousands of people that literally cannot fit on Parliament grounds.
Sheer numbers is the way to get a protest noticed.
