Northland MP Matt King has called on the police to uphold the law and shut down illegal road checkpoints.
Mr King said he had heard from a growing number of Northlanders who were feeling intimidated and harassed at illegal checkpoints that had been set up by "local vigilantes" across the Mid and Far North.
"We live under New Zealand law, and vigilante groups can't just make up their own rules, however well-intentioned," he said.
"Police must intervene and protect those who are just trying to go about their lawful business, including food shopping or moving to essential employment.
"I encourage everyone to stay in their bubble and respect social distancing rules, and for the police to get these illegal checkpoints under control."
