The total volume of retail sales rose 1.7 per cent, seasonally adjusted, to $17.94 billion in the second quarter of this year from a 0.9 per cent growth in the first three months of 2013, according to Statistics New Zealand.
Spending at bars, cafes and restaurants jumped by a record 4.5 per cent to $1.8 billion, seasonally adjusted, in the June quarter.
Dun & Bradstreet New Zealand general manager Lance Crooks said the financial stress index was falling in line with general optimism created by strong house prices, a robust kiwi dollar and positive trade activity.
"With the job market firming and the continuation of low interest rates, we are also seeing consumers more willing to spend on discretionary items, which is something New Zealand's businesses will be hoping builds in the lead-up to Christmas and into the New Year," Crooks said.
Dun & Bradstreet's economic adviser, Stephen Koukoulas, said further easing in consumer financial stress was another sign of improvement in New Zealand's economic conditions.
"With interest rates staying low, employment and wages growth on a steady trend higher, the health of consumer finances continues to improve," Koukoulas said. "An important aspect of the reduction in consumer financial stress is the positive implications this has for further economic activity. The healthier consumer finances are the more likely consumers are to spend."
