While Aucklanders strap in for two weeks in level 3, many residents made attempts to get through Auckland's northern and southern checkpoints.
A police spokesperson said officers dealt with a "significantly higher volume" of vehicles attempting to travel through the checkpoints.
Those who were turned around included people attempting to relocate to a new home, travel for shared childcare arrangements or because they did not have an exemption.
People wanting to move house are allowed to, as long as their place of departure is not in level 3. The same rules apply for those wanting take a child to and from a shared caregiver's place of residence.
As of 11.59pm on Thursday, the majority of travellers aged 12 and above must have a Covid-19 test before they travel.
