Mrs Kaur, 35, of East Bowling, Bradford, the mother of a three-year-old daughter, has now been missing for over a week.
She was last seen on the canal towpath in Roberts Park, Saltaire, at about 1pm on Wednesday, 23 October 2013 after failing to attend nursery school to collect her child.
West Yorkshire Police are increasingly concerned for her welfare because she was taking medication for depression.
Seemberjeet Kaur is described as Asian, 5ft 4ins tall, slim, with straight black shoulder-length hair.
Anyone who has seen her, or has any information about her whereabouts, is asked to contact Bradford CID, via the non-emergency number 101 with details.
A reward is being offered for details or information of the whereabouts or leading to the safe return of Seemberjeet Kaur. For details please contact Sikh Channel in confidence at [cryptex][email protected][/cryptex].
