"Household sector saving is positive for the first time in more than a decade, after borrowing first began to decline several years ago," economic statistics development acting manager Vannessa Turner said in a statement.
However, the impact of the recession on tax revenue, and the one-off hit from the Christchurch earthquakes has been severe for the central and local government sector's savings figures.
In 2007, at the height of the debt boom and when the government was running large Budget surpluses, government sector saving peaked at $11.8 billion. In the year to March 2011, however, the government sector spent $2.4 billion more than it earned.
Overall, New Zealand's national saving was $1.2 billion in the year ended March 2011, compared with $2.0 billion the previous year.
