Christchurch police are appealing for the public's help in locating missing mother Katrina Hill.
Police say Hill, 56, was last seen at 2pm on Wednesday on Westmorland's Ravensdale Rise.
"Police and her family are very concerned about her as it is extremely out of character for her not to be in touch with them," said a police spokesperson.
Police are continuing to look for Hill, but are asking anyone who may have seen her to contact police "urgently".
Hill was last seen wearing a baby blue hoodie, black pants and possibly black shoes. She usually wears glasses.
"Her family want to know that she is okay."
Police are asking anyone with information to contact police on 111 and quote file number 231005/9268
