Six people have been arrested after an "incredibly dangerous" protest saw them sit across State Highway 1 in Wellington, causing traffic queues back to Tawa.
The protesters, who forced the closure of the main motorway into Wellington during peak traffic, have been charged with wilful trespass and criminal nuisance and have been held in custody to appear in the Wellington District Court.
Wellington Area Commander Inspector Dean Silvester said while protest activity is legal, sitting on the motorway is not.
"Being on foot on the motorway is incredibly dangerous, not only for those individuals, but for motorists. We will not hesitate to take action in cases where safety is threatened."
It's the second time in three days the same protest group caused significant traffic delays.
