A woman with a mental impairment has been missing for two days and police now say they hold grave concerns for her.
Mary Berrington, 62, has not been seen since Tuesday night.
A family member spoke to her at her home in Upper Hutt about 9pm. She has not been heard from since.
Now a large search and rescue effort made up of dozens of volunteers and members of the public has been working hard for the past two days in a bid to find Berrington.
A friend of the family's told the Herald tonight people had come from all over Wellington and even Wairarapa to help.
The man, who asked not to be named, said the last person to see or speak to Berrington was her adult daughter.
"She's quite upset, obviously."
An official search and rescue team made up of police officers, local volunteers and members of the public are also searching suburban areas in and around Wellington.
Police urged anyone who may have seen her in the last two days to get in touch immediately, given Berrington's condition.
"Mary has a degree of mental impairment and suffers bi-polar, so may not be in a position to help herself at the moment," a statement said.
"All residents in the Wallaceville and Whakatiki area of Upper Hutt are asked to check their backyards and any structures such as wood sheds or garages in case Mary is taking shelter in them.
"It is also likely that Mary may be hiding in bushes."
Authorities are asking those members of the public wanting to help in the search to stick to main streets, public areas and tracks.
