A car rolled into an Auckland supermarket after a serious crash in Mt Eden critically injured one person this morning.

A person at a local business told the Herald they heard a very loud crash and saw a black car rolling down the road.

Other cars were beeping at it before it hit the Farro gourmet food store on Dominion Rd.

The witness said the black car struck a silver car before rolling back down the road.

They told the Herald no pedestrians were hit.

Police said emergency services were called to the single-vehicle crash on Dominion Rd about 10.18am.
