Emergency services had to remove the driver from the vehicle involved.
Their condition is not known, but they were taken to hospital for treatment.
The incident is understood to have happened shortly after the Government announced New Zealand would be going into a snap level 4 lockdown after a Covid-19 positive case was confirmed in the community.
A 58-year-old man tested positive for the virus after becoming symptomatic over the weekend.
He had travelled with his wife to the Coromandel last Friday where they spent the weekend, before returning to Auckland.
The man and his family are from Devonport, on Auckland's North Shore.
