Tai Tokerau Border Control says it's frightened by the number of people being allowed through the checkpoints around Auckland.
The group - which imposed a lockdown of the Far North in March and April - says it was alarmed to hear reports more than 50,000 vehicles had been let through checkpoints set up on Auckland's northern and southern borders since Wednesday.
Spokesperson Hone Harawira says the police are being too accommodating and should be turning more people away.
Harawira said he was also concerned by the number of people who left the city before the Alert Level 3 restrictions came into place.
He told Morning Report volunteers saw queues of traffic leaving the city before midday.
"That sort of traffic only ever happens at Christmas, or a Covid-19 crisis."
