Police are growing concerned about an Auckland woman who's been missing for nearly a week

Ella Davenport has been missing from her Hain Avenue home in Mangere East since Friday 20 June.

An initial appeal for information was put out at the weekend, but the 57-year old has still not returned home.

Acting Detective Senior Sergeant Rob Kerr says there was a sighting of her near Woolworths Mangere East, on Massey Road on the day she disappeared.

She says Ella was wearing a dark blue long sleeve top, maroon pants and dark coloured shoes.

Kerr says anyone who sees her, should call police immediately.
