Police are reminding the public to make sure they have the correct documentation to leave or drive through Auckland.
If required, police advise motorists to apply for an exemption if they want to enter Auckland.
As Potaka Maipi from Te Ao Māori explains, the first arrest was made today in Hamilton today when a motorist failed to stop at a checkpoint on State Highway One in Mercer.
"So there are fears for others who may attempt to leave through the exit south of Auckland towards Waikato."
Police have also clarified the location of Auckland's lockdown checkpoints, following confusion north of Auckland where residents report being turned away from the police-manned stations.
Eight checkpoints were set up around Auckland's regional boundaries as the city entered alert level 3 at midnight on Sunday, while the rest of the country is at alert level 2.
