For Boxing Day, deals at clothing and jewellery stores (+16.5 per cent), appliance and whiteware stores (+16.6 per cent), electronics retailers (+12 per cent), and floor covering and furniture stores (+17.5 per cent) brought the shoppers in.
"Yesterday was a continuation of the growth in Boxing Day sales we've seen in recent years. It's also an indication that consumer confidence is high due to the improved economy we're seeing at present _ a win-win for retailers as far as we're concerned.''
It was good to see some of the small regions reaping the benefits, he said.
"Gisborne saw the highest growth on Christmas Eve, up almost 36 per cent on the previous year. And yesterday Wairarapa saw an extra $200,000 injected into its local economy, an increase of 17.2 per cent on 2012.''
Auckland/Northland shoppers spent 13.2 per cent more than last year in Boxing Day sales, while Canterbury shoppers spent 15.1 per cent more.
On Christmas Eve, food / liquor retailers (+28 per cent) and department stores (+23.2 per cent) were amongst the biggest winners.
"The huge queues seen at the supermarkets on Christmas Eve were certainly reflected in our stats for the day, as people rushed to get their fresh produce for Christmas lunches and dinners,'' Mr Whiston said.
