One of her sons, Nicholas, said his mother could afford to pay the rates, but the family were livid at getting "absolutely whacked", particularly when their mother hardly used any council services.
Nicholas said he had bought into the Super City vision and had some sympathy for Mayor Len Brown facing severe financial constraints and hurdles to meet Auckland's growth and infrastructure costs.
The National Party voter said the rates system was fundamentally flawed and he was disappointed that John Key recently dismissed alternative funding mechanisms.
"The basis for setting rates is so far out of whack. We have to have a serious look at how to collect revenue," said Nicholas, who suggested a stamp duty on property being made available to councils.
"Just hitting us with a 48 per cent rates rise. Give us a break.
"Len can't be proud of this," said the son.
In a statement, Mr Brown said no one liked the fact some Aucklanders were facing significant rates increases.
"Unfortunately, that is a consequence of the current rating system based on property valuations in a time of dramatic and varied price rises," he said.
Mr Brown said everyone had sympathy for seniors on fixed incomes facing big rates increases and encouraged them to consider options such as the postponement of rates.
Local Government Minister Paula Bennett is overseas and could not be reached for comment about alternative funding mechanisms to property rates.
