In the space of a few months their rates bill shot up from $1300 to $2000, and they have had to stop using the dishwasher.

Family Budgeting Services Federation chief executive Raewyn Fox said the financial picture had changed for Kiwi families since 1992, and not for the better.
There was now a growing number of middle-income families among budget service clientele.
"Back in 1992, unless you were a beneficiary, you were pretty much surviving okay unless a disaster happened," Ms Fox said.
"Now it's right across the board. We are seeing families that may have had reasonable mortgages on a good income, and then there's been a redundancy and all of that changes - we are seeing people really struggle to replace their jobs."
Client numbers had sat between 29,000 and 31,000 for three to four years before leaping up to 41,000 last year and to a record 55,000 this year.
There had also been a near doubling in total debt by clients, jumping from $230 million in 2008 to $441 million this year, of which $110 million was in arrears.
"We are seeing people get in to debt just to tick off the basics, borrowing money to replace the car or because the fridge is broken."
The top five sources of debt were mortgages, government departments, finance companies, bank loans and retailers.
Budgeting services had not seen more consumption, she said.
"Power bills have just soared in the last few years. For a family that is just coping, every time the power goes up $10, that's $10 to take off the food budget - there's nowhere else to take it from."
