Credit growth remained feeble over 2011, Reserve Bank figures show.
The total amount households, farmers and businesses owe their banks rose by $3 billion, or just 1 per cent, in the year.
Households remained wary of debt. Annual growth in mortgage debt in December at 1.2 per cent was down from 1.8 per cent a year earlier and 3.5 per cent in December 2009. Consumer debt fell 0.3 per cent.
By contrast turnover in the housing market in December was 21 per cent higher than a year earlier, according to the Real Estate Institute, though still 30 per cent below the December average between 2003 and 2007.
Infometrics economist Matt Nolan said it appeared households had been trading houses among themselves rather than using mortgage money to buy new builds or consumer goods.
