She said her mother was robbed of "every penny" she had.
Police investigating that attack and a spate of home invasions targeting elderly women yesterday arrested a man, William John Murphy. But they have reiterated that elderly people should remain vigilant.
A warrant to arrest Murphy, 36, was issued on Sunday after police identified him as a "key person of interest" in their investigation into the series of robberies involving elderly women in their homes.
Murphy has been charged in relation to one incident as the police investigation continues. Police described Murphy's arrest as "significant" but were still urging older citizens not to let their guard down. "The investigation still has a long way to go and it's important people keep an open mind," Detective Inspector Karyn Malthus said.
"We remain concerned about the safety of our elderly being targeted and are yet to determine the identity of the offender purporting to be a police officer in various guises. We therefore urge communities to be cautious about cold-callers and to remain vigilant about personal security."
Police had earlier released an image taken from bank security footage of a man using a bank card stolen from a 79-year-old woman during a robbery in Westmere.
Murphy was arrested after a dramatic escape attempt on Auckland's Northern Motorway about 8am yesterday. Police found him hiding in the Puhoi River after he allegedly crashed a stolen car just north of the Northern Motorway toll tunnel.
He will appear in the Auckland District Court today on two charges.
Murphy's family in Northland were reluctant to speak about him. "We don't want to know anything about it," said a male relative.
