A car has ploughed into a house in a central Auckland suburb this morning.

Fire Service shift manager Jaron Phillips said people were being treated for minor injuries after the car hit the house on Great North Rd in Waterview at about 6.30am.

Mr Phillips said it was not clear how many people were injured or if they were all travelling in the vehicle when the accident happened.

The crash is on one of Auckland's busiest arterial roads that leads to the Northwestern Motorway.
